2020-2021 Recommendation Highlights

Influenza Activity During the 2019-2020 influenza Season

National

Influenza activity during the 2019-2020 season in the United States was characterized by two consecutive waves of activity, the first driven mostly by influenza B/Victoria viruses and the second driven by A(H1N1)pdm09 viruses. Overall, influenza A(H1N1)pdm09 viruses were the most commonly reported influenza viruses this season.  Laboratory confirmed influenza activity decreased quickly during March 2020 and has remained at low levels since early April, likely due in part to implementation of community prevention measures aimed at mitigating the spread and impact of SARS-CoV-2, the virus that causes COVID-19.

Influenza severity indicators (hospitalization and mortality rates) were moderate to low overall during the 2019-2020 season, but the relative impact of influenza on hospitalization rates differed by age group. Rates among children 0-4 years old and adults 18-49 years old were the highest CDC has on record for these age groups, surpassing the rates reported during the 2009 H1N1 pandemic. Hospitalization rates for school-aged children (5-17) were higher than any recent regular season but remain lower than rates experienced by this age group during the 2009 H1N1 pandemic. As of August 29, 2020 CDC reported 188 flu-related pediatric deaths during the 2019-2020 season.  This matches the highest recorded number of influenza associated pediatric deaths during a regular influenza season, which occurred during the 2017-2018 season. 

Massachusetts

Massachusetts also saw a first wave of influenza B/Victoria activity and then a second wave of Influenza A (H1N1) viruses. Influenza A (H1N1) activity began an uptick soon after the first of the year. Influenza-Like Illness (ILI) activity in Massachusetts remained high for several more weeks this flu season when compared to the last five flu seasons. However, with the likely influence of the COVID-19 pandemic, it is difficult to discern the influence of COVID-19 on ILI activity remaining elevated.  Hospitalizations among MA residents were higher than in the previous 2018-2019 season.  There was only 1 pediatric death due to influenza in MA last season.

Recommendations

Prevention and Control of Seasonal Influenza with Vaccines: Recommendations of the Advisory Committee on Immunization Practices — United States, 2020-2021 Influenza Season” has been published. CDC recommends annual influenza vaccination for everyone 6 months and older with any licensed, age appropriate flu vaccine (IIV, RIV4, or LAIV4) with no preference expressed for any one vaccine over another.

For more information on this year’s flu recommendations, see:

Flu Vaccine

What viruses will the 2020-2021 flu vaccines protect against?

There are many different flu viruses and they are constantly changing. The composition of U.S. flu vaccines is reviewed annually and updated as needed to match circulating flu viruses. Flu vaccines protect against the three or four viruses (depending on the vaccine) that research suggests will be most common.

For 2020-2021, trivalent (three-component) egg-based vaccines are recommended to contain:

  • A/Guangdong-Maonan/SWL1536/2019 (H1N1) pdm09-like virus (updated)
  • A/Hong Kong/2671/2019 (H3N2)-like virus (updated)
  • B/Washington/02/2019 (B/Victoria lineage)-like virus (updated)

Quadrivalent (four-component) egg-based vaccines, which protect against a second lineage of B viruses, are recommended to contain:

  • the three recommended viruses above, plus B/Phuket/3073/2013-like (Yamagata lineage) virus.

For 2020-2021, cell- or recombinant-based vaccines are recommended to contain:

  • A/Hawaii/70/2019 (H1N1)pdm09-like virus (updated)
  • A/Hong Kong/45/2019 (H3N2)-like virus (updated)
  • B/Washington/02/2019 (B/Victoria lineage)-like virus (updated)
  • B/Phuket/3073/2013-like (Yamagata lineage) virus

Are there any changes to the 2020-2021 Northern Hemisphere vaccines from what was included in this season’s 2019-2020 U.S. flu vaccines?

Yes, this season’s flu vaccines were updated to better match viruses expected to be circulating in the United States.

  • The egg-based H1N1 vaccine component was updated from an A/Brisbane/02/2018 (H1N1)pdm09-like virus to an A/Guangdong-Maonan/SWL1536/2019 (H1N1)pdm09-like virus.
  • The cell- or recombinant-based H1N1 vaccine component was updated from an A/Brisbane/02/2018 (H1N1)pdm09-like virus to an A/Hawaii/70/2019 (H1N1)pdm09-like virus.
  • The egg-based H3N2 vaccine component was updated from an A/Kansas/14/2017 (H3N2)-like virus to an A/Hong Kong/2671/2019 (H3N2)-like virus.
  • The cell- or recombinant-based H3N2 vaccine component was updated from an A/Kansas/14/2017 (H3N2)-like virus to an A/Hong Kong/45/2019 (H3N2)-like virus.
  • The B/Victoria lineage vaccine component was updated from a B/Colorado/06/2017 (B/Victoria lineage)-like virus to a B/Washington/02/2019 (B/Victoria lineage)-like virus.
  • The B/Yamagata lineage vaccine component was not updated.

Are there any new vaccines licensed for use during the 2020-2021 flu season?

There are two new vaccines licensed for use during the 2020-2021 flu season.

  • The first is a quadrivalent high-dose vaccine licensed for use in adults 65 years and older. This vaccine will replace the previously licensed trivalent high-dose vaccine.
  • The second new vaccine that will be available is a quadrivalent adjuvanted vaccine licensed for use in adults 65 years and older.
    • This vaccine is similar to the previously licensed trivalent vaccine containing MF59 adjuvant, but it has one additional influenza B component.

For more information: see new vaccines available this year.

What flu vaccines are recommended this season?

For the 2020-2021 flu season, providers may choose to administer any licensed, age-appropriate flu vaccine (IIV, RIV4, or LAIV4) with no preference for any one vaccine over another.  See Table 1 on page 3 of this season’s ACIP recommendations for summary of flu formulations by age, dose volume and route

Vaccine options this season include:

Do we need to get a flu vaccine earlier this year (i.e. July/August)?

There is no change in CDC’s recommendation on timing of vaccination this flu season. Getting vaccinated in July or August is too early, especially for older people, because of the likelihood of reduced protection against flu infection later in the flu season. September and October are good times to get vaccinated. However, as long as flu viruses are circulating, vaccination should continue, even in January or later.

For more information, see vaccination timing this year.

Will there be changes in how and where flu vaccine is given this fall and winter?

How and where people get a flu vaccine may need to change due to the COVID-19 pandemic. CDC works with healthcare providers and state and local health departments to develop contingency plans on how to vaccinate people against flu without increasing their risk of exposure to respiratory germs, like the virus that causes COVID-19, and has released Interim Guidance for Immunization Services during the COVID-19 Pandemic. More information is available in the ‘Administering Flu Vaccines during the COVID-19 Pandemic’ section below.

Some settings that usually provide flu vaccine, like workplaces, may not offer vaccination this upcoming season, because of the challenges with maintaining social distancing. For more information on where you can get a flu vaccine, visit Vaccine Finder.  This site has a link to MedFinder which lists places where prescriptions can be filled for flu antiviral medications.

Information on getting a flu vaccine safely this season is available in the ‘Getting a Flu Vaccine during the COVID-19 Pandemic’ section below.

How many flu vaccines are expected to be available for the 2020-2021 flu season?

Flu vaccine is produced by private manufacturers, so supply depends on manufacturers. For the 2020-2021 season, manufacturers have projected they will provide as many as 194-198 million doses of flu vaccine, which is more than the 175 million dose record set during the 2019-2020 flu season.

Are there delays in the availability of flu vaccine?

Currently, vaccine manufacturers are not reporting any significant delays in distributing flu vaccine this season. Because a record number of flu vaccine doses are being manufactured this year, the time to produce and distribute them will be longer. CDC will continue to provide weekly updates on total flu vaccine doses distributed throughout the 2020-2021 flu season. Use the VaccineFinder to find out where to get vaccinated near you.

Flu and COVID-19

What is the difference between Influenza (Flu) and COVID-19?

Influenza (Flu) and COVID-19 are both contagious respiratory illnesses, but they are caused by different viruses. COVID-19 is caused by infection with a new coronavirus (called SARS-CoV-2) and flu is caused by infection with influenza viruses. Because some of the symptoms of flu and COVID-19 are similar, it may be hard to tell the difference between them based on symptoms alone, and testing may be needed to help confirm a diagnosis. Flu and COVID-19 share many characteristics, but there are some key differences between the two.

While more is learned every day, there is still a lot that is unknown about COVID-19 and the virus that causes it. This table​ compares COVID-19 and flu, given the best available information to date.

To learn more about COVID-19, visit Coronavirus (COVID-19).

To learn more about flu, visit Influenza (Flu).

Will there be flu along with COVID-19 in the fall and winter?

While it’s not possible to say with certainty what will happen in the fall and winter, CDC believes it’s likely that flu viruses and the virus that causes COVID-19 will both be spreading. In this context, getting a flu vaccine will be more important than ever. CDC recommends that all people 6 months and older get a yearly flu vaccine.

Can I have flu and COVID-19 at the same time?

Yes. It is possible have flu, as well as other respiratory illnesses, and COVID-19 at the same time. Health experts are still studying how common this can be.

Some of the symptoms of flu and COVID-19 are similar, making it hard to tell the difference between them based on symptoms alone. Diagnostic testing can help determine if you are sick with flu or COVID-19. See also: CDC’s Antiviral Summary for Clinicians, which includes a section about the interpretation of diagnostic testing and antiviral treatment.

Is there a test that can detect both flu and COVID-19?

Yes. CDC has developed a test that will check for A and B type seasonal flu viruses and SARS CoV-2, the virus that causes COVID-19. This test will be used by U.S. public health laboratories. Testing for these viruses at the same time will give public health officials important information about how flu and COVID-19 are spreading and what prevention steps should be taken. The test will also help public health laboratories save time and testing materials, and to possibly return test results faster.

The Food and Drug Administration (FDA) has given CDC an Emergency Use Authorization for this new test. Initial test kits were sent to public health laboratories in early August 2020. CDC will continue to manufacture and distribute these kits. 

More information for laboratories is available.

Will the new test that detects both flu and COVID-19 replace other tests?

No. This new test is designed for use at CDC-supported public health laboratories at state and local levels, where it will supplement and streamline surveillance for flu and COVID-19. The use of this specialized test will be focused on public health surveillance efforts and will not replace any COVID-19 tests currently used in commercial laboratories, hospitals, clinics, and other healthcare settings.

CDC’s first viral test for SARS-CoV-2 (the CDC 2019-nCoV Real-Time RT-PCR Diagnostic Panel (ER-34)) will still be available for qualified laboratories to order through the International Reagent Resource (IRR). The new multiplex assay can also be ordered through the IRR. Check the IRR website for details.

For additional questions, please visit: Clinical Questions about COVID-19: Questions and Answers: Testing, Diagnosis and Notification.

Is COVID-19 more dangerous than flu?

Flu and COVID-19 can both result in serious illness, including illness resulting in hospitalization or death. While there is still much to learn about COVID-19, at this time, it does seem as if COVID-19 is more deadly than seasonal influenza; however, it is too early to draw any conclusions from the current data. This may change as we learn more about the number of people who are infected who have mild illnesses.

Will a flu vaccine protect me against COVID-19?

Getting a flu vaccine will not protect against COVID-19, however flu vaccination has many other important benefits. Flu vaccines have been shown to reduce the risk of flu illness, hospitalization and death. Getting a flu vaccine this fall will be more important than ever, not only to reduce your risk from flu but also to help conserve potentially scarce health care resources.

Getting a Flu Vaccine during the COVID-19 Pandemic

If coronavirus disease 2019 (COVID-19) is spreading in my community, should I still go out to get a flu vaccine?

Yes. Getting a flu vaccine is an essential part of protecting your health and your family’s health this season. To protect your health when getting a flu vaccine, follow CDC’s recommendations for running essential errands and doctor visits. Continue to take everyday preventive actions.

How can I safely get a flu vaccine if COVID-19 is spreading in my community?

When going to get a flu vaccine, practice everyday preventive actions and follow CDC recommendations for running essential errands.

Ask your doctor, pharmacist, or health department if they are following CDC’s vaccination pandemic guidance. Any vaccination location following CDC’s guidance should be a safe place for you to get a flu vaccine.

If I am at high risk for serious illness from COVID-19 or flu, where is the safest place for them to get a flu vaccine?

You can safely get a flu vaccine at multiple locations including your doctor’s office, health departments, and pharmacies. You can use VaccineFinder.org to find where flu vaccines are available near you. When going to get a flu vaccine, be sure to practice everyday preventive actions.

Ask your doctor, pharmacist, or health department if they are following CDC’s vaccination pandemic guidance. Any vaccination location following CDC’s guidance should be a safe place for you to get a flu vaccine. See the section below: Administering Flu Vaccine during the COVID-19 Pandemic for more guidance foe administration of vaccines during the pandemic.

Vaccination of people at high risk for flu complications is especially important to decrease their risk of severe flu illness. Many people at higher risk from flu also seem to be at higher risk from COVID-19. If you are at high risk, it is especially important for you to get a flu vaccine this year.

Are there special precautions my doctor, pharmacist, or health department should take this flu season to make sure flu vaccines can be given safely during the COVID-19 pandemic?

Yes. CDC has resources to help providers safely administer vaccine during the COVID-19 pandemic. Ask your doctor, pharmacist, or health department if they are following CDC’s vaccination pandemic guidance.  And protect yourself by practicing everyday preventive actions.

If an individual does not have a primary care provider, where can they get a flu vaccine?

If you don’t have a doctor that you regularly see, flu vaccines are also available at locations including health departments and pharmacies. You can use VaccineFinder.org to find where flu vaccines are available near you.

Flu Activity

Will new flu viruses circulate this season?

Flu viruses are constantly changing so it’s not unusual for new flu viruses to appear each year. More information about how flu viruses change is available.

When will flu activity begin and when will it peak?

The timing of flu is difficult to predict and can vary in different parts of the country and from season to season.

Administering Flu Vaccines during the COVID-19 Pandemic

Is there guidance for safely administering vaccines during the COVID-19 pandemic?

CDC has released Interim Guidance for Immunization Services during the COVID-19 Pandemic. This guidance is intended to help immunization providers in a variety of clinical and alternative settings with the safe administration of vaccines during the COVID-19 pandemic. This guidance will be continually reassessed and updated based on the evolving epidemiology of COVID-19 in the United States. Healthcare providers who give vaccines should also consult guidance from state, local, tribal, and territorial health officials.

For the complete interim guidance for immunization services during the COVID-19 pandemic.

Why is it important for influenza (flu) vaccines to be given during the COVID-19 pandemic?

Efforts to reduce the spread of COVID-19, such as stay-at-home and shelter-in-place orders, have led to decreased use of routine preventive medical services, including immunization services. Ensuring that people continue or start getting routine vaccinations during the COVID-19 pandemic is essential for protecting people and communities from vaccine-preventable diseases and outbreaks, including flu. Routine vaccination prevents illnesses that lead to unnecessary medical visits and hospitalizations, which further strain the healthcare system.

For the upcoming flu season, flu vaccination will be very important to reduce flu because it can help reduce the overall impact of respiratory illnesses on the population and thus lessen the resulting burden on the healthcare system during the COVID-19 pandemic.

A flu vaccine may also provide several individual health benefits, including keeping you from getting sick with flu, reducing the severity of your illness if you do get flu and reducing your risk of a flu-associated hospitalization.

Who should get their flu vaccine during the COVID-19 pandemic?

Annual flu vaccination is recommended for everyone 6 months of age and older, with rare exceptions, because it is an effective way to decrease flu illnesses, hospitalizations, and deaths.

During the COVID-19 pandemic, reducing the overall burden of respiratory illnesses is important to protect vulnerable populations at risk for severe illness, the healthcare system, and other critical infrastructure. Thus, healthcare providers should use every opportunity during the influenza vaccination season to administer influenza vaccines to all eligible persons, including;

  • Essential workers: Including healthcare personnel (including nursing home, long-term care facility, and pharmacy staff) and other critical infrastructure workforce
  • Persons at increased risk for severe illness from COVID-19: Including adult’s aged 65 years and older, residents in a nursing home or long-term care facility, and persons of all ages with certain underlying medical conditions. Severe illness from COVID-19 has been observed to disproportionately affect members of certain racial/ethnic minority groups
  • Persons at increased risk for serious influenza complications: Including infants and young children, children with neurologic conditions, pregnant women, adults aged 65 years and older, and other persons with certain underlying medical conditions

Should a flu vaccine be given to someone with suspected or confirmed COVID-19?

No. Vaccination should be deferred (postponed) for people with suspected or confirmed COVID-19, regardless of whether they have symptoms, until they have met the criteria to discontinue their isolation. While mild illness is not a contraindication to flu vaccination, vaccination visits for these people should be postponed to avoid exposing healthcare personnel and other patients to the virus that causes COVID-19. When scheduling or confirming appointments for vaccination, patients should be instructed to notify the provider’s office or clinic in advance if they currently have or develop any symptoms of COVID-19.

Additionally, a prior infection with suspected or confirmed COVID-19 or flu does not protect someone from future flu infections. The best way to prevent seasonal flu is to get vaccinated every year.

What steps can healthcare personnel take to safely give flu vaccine during the COVID-19 pandemic?

The potential for asymptomatic spread of the virus that causes COVID-19 underscores the importance of applying infection prevention practices to encounters with all patients, including physical distancing (at least 6 feet) when possible, respiratory and hand hygiene, surface decontamination, and source control while in a healthcare facility. Immunization providers should refer to the guidance developed to prevent the spread of COVID-19 in healthcare settings, including outpatient and ambulatory care settings.

To help ensure the safe delivery of care during vaccination visits, providers should:

  • Minimize chances for exposures, including steps such as these:
    • Screen patients for symptoms of COVID-19 and contact with persons with possible COVID-19 prior to and upon their arrival at the facility, and isolate symptomatic patients as soon as possible.
    • Limit and monitor points of entry to the facility and install barriers, such as clear plastic sneeze guards, to limit physical contact with patients at triage.
    • Implement policies for adults and children over the age of 2 years to wear cloth face coverings (if tolerated).
    • Ensure patients practice respiratory hygiene, cough etiquette, and hand hygiene.
  • Ensure all staff adhere to the following infection prevention and control procedures:
    • Follow Standard Precautions, which include guidance for hand hygiene and cleaning the environment between patients.
    • Wear a medical facemask at all times.
    • Use eye protection based on level of community transmission of the virus that causes COVID-19:
      • Moderate-to-substantial transmission: Healthcare providers should wear eye protection given the increased likelihood of encountering asymptomatic COVID-19 patients.
      • Minimal-to-no transmission: Universal eye protection is considered optional, unless otherwise indicated as a part of Standard Precautions.
  • Consider these additional steps during vaccine administration:
    • Intranasal or oral vaccines:
      • Healthcare providers should wear gloves when giving intranasal or oral vaccines because of the increased likelihood of coming into contact with a patient’s mucous membranes and body fluids. They should change their gloves and wash their hands between patients.
      • Giving these vaccines is not considered an aerosol-generating procedure and thus, the use of an N95 or higher-level respirator is not recommended.
    • Intramuscular or subcutaneous vaccines:
  • For patients (sick or well) presenting for care or routine visits, ensure physical distancing by implementing strategies, such as:
    • Separating sick from well patients by scheduling these visits during different times of the day (e.g., well visits in the morning and sick visits in the afternoon), placing patients with sick visits in different areas of the facility, or scheduling patients with sick visits in a different location from well visits (when space is available).
    • Reduce crowding in waiting areas by asking patients to remain outside (e.g., stay in their vehicles, if applicable) until they are called into the facility for their appointment.
    • Ensure that physical distancing measures, with separation of at least 6 feet between patients and visitors, are maintained during all aspects of the visit, including check-in, checkout, screening procedures, and postvaccination monitoring. Use strategies such as physical barriers, signs, ropes, and floor markings.
    • Use electronic communications as much as possible (e.g., filling out needed paperwork online in advance) to minimize patients’ time in the office as well as their sharing of materials (e.g., clipboards, pens).

Is there guidance for giving flu vaccine in settings other than a doctor’s office (e.g., pharmacies; temporary, off-site, or satellite clinics; and large-scale influenza clinics)?

Yes. Guidance has been developed for giving vaccines at pharmacies, temporary, off-site or satellite clinics and  large-scale influenza clinics. Other approaches to vaccination during the COVID-19 pandemic may include drive-through immunization services at fixed sites, curbside clinics, mobile outreach units, and home visits.

The general principles outlined for healthcare facilities should also be applied to alternative vaccination sites, with additional precautions for physical distancing that are particularly relevant for large-scale clinics, such as:

  • Providing specific appointment times or other strategies to manage patient flow and avoid crowding.
  • Ensuring sufficient staff and resources to help move patients through the clinic as quickly as possible.
  • Limiting the overall number of patients at any given time, particularly for populations at higher risk for severe illness from COVID-19.
  • Setting up a one-way flow through the site and using signs, ropes, or other measures to direct patient traffic and ensure physical distancing between patients.
  • Arranging a separate vaccination area or separate hours for persons at increased risk for severe illness from COVID-19, such as older adults and persons with underlying medical conditions, when feasible.
  • Selecting a space large enough to ensure a minimum distance of 6 feet between patients in line or in waiting areas for vaccination, between vaccination stations, and in postvaccination monitoring areas (the Advisory Committee on Immunization Practices recommends that providers consider observing patients for 15 minutes after vaccination to decrease the risk for injury should they faint).

Influenza disease burden

The burden of disease is great. CDC estimates that influenza has resulted in between 9 million and 45 million illnesses, between 140,000 and 810,000 hospitalizations and between 12,000 and 61,000 deaths annually since 2010.

CDC now posts preliminary estimates of the influenza disease burden.

The good news is this year’s influenza vaccines have been updated to better match circulating viruses.

Your strong recommendation is important!

A health care provider’s strong recommendation is a critical factor affecting whether your patent gets influenza vaccine. Patients listen to providers when providers strongly recommend vaccination.

  • There are many misconceptions about flu vaccine.  CDC addresses many of these misconceptions and provides a summary of the benefits of vaccination and selected scientific studies that support these benefits.
  • Flu vaccine is recommended for everyone 6 months of age and older who do not have contraindications.. While some flu formulations are not recommended for some patients and some patients should not receive flu vaccine at all, this is uncommon.  For more guidance on contraindications and precautions for influenza vaccine, please see Table 2 on page 5 and pages 14-16 in the 2020-2021 ACIP Influenza Recommendations.

Below are and links to the latest information and data that might inform your conversations with patients in the upcoming months:

  • Flu vaccine offers the best protection against flu-related illness, hospitalization, and death.  Flu vaccine reduces this burden of illness. For the latest information about vaccine effectiveness, see CDC’s Influenza Vaccine Effectiveness Studies website.
  • Influenza vaccination was found to reduce deaths in children. A study in Pediatrics was the first of its kind to show that influenza vaccination is effective in preventing influenza-associated deaths among children.  As of August 21, 2020, a total of 188 pediatric deaths had been reported to CDC during the season.  This is the highest number reported since the 2017-2018 season.
  • Influenza vaccination may make illness milder. While some people who get vaccinated may develop influenza, vaccination may make their illness milder. A 2017 study in Clinical Infectious Diseases (CID) showed that influenza vaccination reduced deaths, intensive care unit (ICU) admissions, ICU length of stay, and overall duration of hospitalization among hospitalized influenza patients.
  • Influenza vaccination has been found effective in preventing influenza-associated hospitalization during pregnancy.

For more information on questions and answers related to this flu season, please see the General information about flu page.

Vaccine supply

MDPH universally provides influenza vaccine, as well as other routinely recommended vaccines, to all children through 18 years of age. MDPH only provides influenza vaccine for uninsured adults seen at public sites. For more information on state-supplied vaccine, please see the Vaccine Management page. 

Nationally, manufacturers have projected they will provide as many as 194-198 million doses of flu vaccine this season, which is more than the 175 million dose record set during the 2019-2020 flu season.Information about the national vaccine supply can be found at CDC’s Seasonal Influenza Vaccine Supply & Distribution website.  

The Immunization Action Coalition (IAC) has a very helpful table of the Influenza Vaccine Products for the 2020-2021 Influenza Season.

When to vaccinate

Optimally, vaccination should occur before the onset of influenza activity in the community. CDC recommends flu vaccination by the end of October, if possible. This year it is particularly important that vaccination efforts continue into November, the winter months and throughout the season, as both flu and COVID-19 will be active in the U.S.  The duration of the influenza season varies from, year to year and influenza activity might not occur in certain communities until February or March. In New England, flu activity usually lasts until April and May.

To avoid missed opportunities, providers should continue to offer vaccination during routine health care visits and hospitalizations.  Immunization providers might need to adapt and extend the duration of vaccination campaigns to accommodate stay at home efforts and social distancing aimed at slowing the spread of COVID-19.

Safe influenza vaccine administration

CDC provides comprehensive vaccine administration resources, including Vaccine Administration eLearn at their Vaccine Administration website.
