Before getting vaccinated
Will I have to pay for the vaccine?
No. The vaccine is being provided free of charge to all individuals by the federal government. If you have insurance, it will be billed at no cost to you. However, you do not need to be insured to receive the vaccine. You will never be asked for a credit card number to make an appointment.
May undocumented immigrants receive the vaccine for free?
Yes. The vaccine itself is free for all individuals in Massachusetts. Health insurance (including Medicare and Medicaid) will cover the cost of administering the vaccine. For patients without health insurance, health care providers may request reimbursement from the federal government for the cost of administering vaccine to undocumented immigrants.
Can I still get the vaccine if I don't have an ID card?
Yes. You can get a vaccine even if you do not have insurance, a driver’s license or a Social Security number. For more information, visit How to prepare for your COVID-19 vaccine appointment.
Will getting the vaccine negatively impact a person’s immigration status?
No. The federal government has confirmed that it will not consider COVID-19 treatment (including a vaccine) as part of a determination of whether someone is a “public charge” or as it relates to the public benefit condition for certain individuals seeking an extension of stay or change of status, even if the vaccine is paid for by Medicaid or other federal funds.
Is a patient’s vaccination record protected from disclosure?
The Department of Public Health will maintain an electronic record of each patient in Massachusetts who receives the COVID-19 vaccine. The vaccine database is kept confidential like a patient’s medical record with his or her doctor.
Will I need to be tested for COVID-19 before getting the vaccine?
No, a COVID-19 test is not needed before getting the vaccine.
Should someone who is COVID-19-positive receive the vaccine?
No. People who are known to have COVID-19 should wait to be vaccinated until their isolation period has ended, usually 10 days after symptoms started or, if they didn’t have symptoms, 10 days after their test was positive.
Should people who have had COVID-19 be vaccinated?
Yes, people who have previously had COVID-19 should be vaccinated. Experts do not yet know how long you are protected from getting sick again after recovering from COVID-19. Evidence is emerging that people get better protection by being fully vaccinated compared with having had COVID-19. Even if you have already recovered from COVID-19, it is possible—although rare—that you could be infected with the virus that causes COVID-19 again.
Can people who live in another state or country part time (e.g. students, retirees, people with dual citizenship) get the COVID-19 vaccine in Massachusetts?
Yes. The Massachusetts COVID-19 Vaccination program is intended for individuals who live, work or study in the Commonwealth. You may also get your second dose in Massachusetts if you received the first dose in another state. Please be sure to keep the vaccination card you were given at the time of the first dose.
What are the benefits of getting a COVID-19 vaccine?
COVID-19 vaccination will help keep you from getting sick from COVID-19. All COVID-19 vaccines available in the U.S. have been shown to be very effective. Experts continue to conduct more studies about whether the vaccines also keep people from spreading COVID-19. Wearing masks and social distancing help lower your chance of getting the virus or spreading it to others, but these measures are not enough. The combination of getting vaccinated and following CDC’s recommendations to protect yourself and others will offer the best protection from COVID-19.
Will vaccines work against COVID-19 variants?
It is normal for viruses to change as they spread, and for new variants to appear. The CDC is monitoring virus changes in the United States, including changes with the Delta variant. Scientists are working to learn more about how easily each variant spreads, whether they could cause more severe illness, and whether the vaccines we already have will protect people against specific COVID-19 variants. So far, studies suggest that the vaccines provide protection from the known variants. Even when a vaccinated person gets infected with COVID-19, they are very protected against severe disease and death. Learn more at About Variants of the Virus that Causes COVID-19 | CDC.
Does the Johnson & Johnson COVID-19 vaccine provide as much protection as the Pfizer and Moderna vaccines?
All three FDA-approved or authorized COVID-19 vaccines are safe and highly effective against serious illness, hospitalization, and death. The Janssen (Johnson & Johnson) vaccine was also shown to be effective against some COVID-19 variants, with research conducted in countries with these more infectious variants including South Africa and Brazil. An added benefit is that the Janssen (Johnson & Johnson) vaccine requires only a single shot – so if you are offered it, you are “one and done” and don’t need to make a second appointment.
What is an Emergency Use Authorization?
Three vaccines – Pfizer, Moderna, and Janssen (Johnson & Johnson) – have received Emergency Use Authorization (EUA) from the federal Food and Drug Administration. Pfizer has also been approved for people ages 16 and older. Learn more about what this means – and other information about the vaccines – in the FDA fact sheets for recipients and caregivers: Comirnaty/Pfizer, Moderna, and Johnson & Johnson (Janssen).
What does it mean now that the Pfizer COVID-19 vaccine has FDA approval?
On 8/23/21, the U.S. Food and Drug Administration (FDA) approved the first COVID-19 vaccine. The vaccine has been known as the Pfizer COVID-19 Vaccine and will now be marketed as Comirnaty (koe-mir’-na-tee), for the prevention of COVID-19 in people 16 years of age and older. Comirnaty is the same vaccine as the Pfizer vaccine. The Pfizer vaccine is also still available under emergency use authorization (EUA) for people ages 5 through 15.
Compared to an EUA, FDA approval of vaccines requires even more data on safety, manufacturing, and effectiveness over longer periods of time and includes real-world data. The full approval by the FDA means that the Comirnaty vaccine now has the same level of approval as other vaccines routinely used in the U.S., such as vaccines for hepatitis, measles, chicken pox, and polio. The Pfizer COVID-19 vaccine was the first vaccine to receive emergency authorization, which is why it is the first to have enough data to receive full approval. It does not mean anything about the safety and effectiveness of the Moderna or Johnson & Johnson vaccine.
During your appointment
What can I expect at my appointment to get vaccinated for COVID-19?
Please visit Getting Your COVID-19 Vaccine | CDC for tips on what to expect when you get vaccinated, what information your provider will give you, and resources you can use to monitor your health after you are vaccinated.
Do I need to wear a mask when I receive a COVID-19 vaccine?
Yes, you must wear a mask that covers your nose and mouth during your appointment.
How long do I have to wait between the first and second dose of the COVID-19 vaccine for Pfizer and Moderna?
Your second shot is recommended at 21 days for Pfizer and 28 days for Moderna. However, if you get the second shot at any time after the recommended date, you are still considered fully vaccinated. You should not get the second dose earlier than 21 days for Pfizer or 28 days for Moderna. The Janssen (Johnson & Johnson) vaccine is only one dose.
How effective is one dose of a Pfizer or Moderna COVID-19 vaccine compared to two doses?
The Pfizer and Moderna COVID-19 vaccines were not studied for use as a single dose. People should get both doses of the vaccine to be fully vaccinated.
Will I be monitored after being vaccinated?
People who have a history of anaphylaxis (severe allergic reaction) from any cause are observed for 30 minutes. All others are monitored for 15 minutes.
Will I receive anything to show proof of vaccination?
You should receive a vaccination card or printout that tells you what COVID-19 vaccine you received, the date you received it, and where you received it. Please be sure to keep this card for your second dose. You may take a photo of your card as a backup digital copy.
You should receive a paper or electronic version of a fact sheet that tells you more about the specific COVID-19 vaccine you are being offered. Each COVID-19 vaccine has its own fact sheet that contains information to help you understand the risks and benefits of receiving that specific vaccine: Comirnaty/Pfizer, Moderna, and Johnson & Johnson (Janssen).
What should I do if I lose my COVID-19 Vaccination Record Card? (Updated 1/11/22)
You have a few options:
- Contact your healthcare provider or the location where you were vaccinated. They can print out another copy of your record.
- Get a digital copy of your vaccination record through MyVaxRecords.Mass.Gov.
- Your record will also be in v-safe, if you enrolled in the program.
- You can fill out an Immunization Record Request Form that goes directly to the state Department of Public Health. If you use this form, you will get a complete history of all vaccines you’ve gotten, not just the COVID-19 vaccine, and it can take up to 6 weeks to get your records.
- Please note that this form must be notarized before it is submitted and mailed in hard copy. You will receive a paper record of any immunizations you have received that were reported to the MIIS. You will not receive a COVID-19 vaccine card.
If you were vaccinated at a mass vaccination site, view the instructions for vaccination record requests.
After getting vaccinated
What should I do if I experience symptoms after receiving a COVID-19 vaccine?
Some people have side effects after being vaccinated (such as tiredness, headache, and pain at the injection site), which are normal signs that your body is building protection. These side effects may affect your ability to do daily activities, but they should go away in a few days. If you develop respiratory symptoms like runny nose, cough, or loss of sense of smell or taste, you should consider getting tested for COVID-19 or talk to your healthcare provider. It is possible to get COVID-19 even after you get the vaccine. Stay home if you are sick and avoid close contact with others. You may wish to check with your employer about how this will impact your work.
If you have any significant pain or discomfort, talk to your healthcare provider, who may recommend over-the-counter medicine, such as ibuprofen or acetaminophen. To reduce pain and discomfort where you got the shot apply a clean, cool, wet washcloth over the area, and use or exercise your arm. To reduce discomfort from fever, drink plenty of fluids and dress lightly. In most cases, discomfort from fever or pain is normal, but contact your healthcare provider if:
- the redness or tenderness where you got the shot increases after 24 hours
- your side effects are worrying you or do not seem to be going away after a few days
How do I report if I have any side effects after getting the COVID-19 vaccine?
V-safe is a smartphone-based tool that uses text messaging and web surveys to provide personalized health check-ins after you receive a COVID-19 vaccination. Through v-safe, you can quickly tell CDC if you have any side effects after getting the COVID-19 vaccine. Depending on your answers, someone from CDC may call to check on you and get more information. And v-safe will remind you to get your second COVID-19 vaccine dose if you need one. To sign up for v-safe, please visit V-safe After Vaccination Health Checker | CDC.
If you have any concerns, you can also call your healthcare provider. You or your provider can report any side effects to the Vaccine Adverse Event Reporting System (VAERS), which is a national system run by the federal government.
How long after getting the COVID-19 vaccine does it take to be effective?
It usually takes a few weeks for the body to build immunity after vaccination. That means it's possible a person could be infected with the virus that causes COVID-19 just before or just after vaccination and get sick. This is because the vaccine has not had enough time to provide protection. You are considered fully vaccinated if you have received two doses of either the Moderna or Pfizer COVID-19 vaccines or a single dose of the Janssen (Johnson & Johnson) vaccine more than 14 days ago.
How long does protection from the COVID-19 vaccines last?
It’s not yet known how long COVID-19 vaccine protection lasts. Recent studies show that protection against the virus may decrease over time. That is why the CDC recommends certain groups get a booster shot.
When can I get a booster shot?
For information about what boosters are, who is eligible, and how to get one, visit COVID-19 booster frequently asked questions | Mass.gov.
What guidance do I need to follow after I am fully vaccinated?
People who have been fully vaccinated can start to do some things that they had stopped doing because of the pandemic. For more information, please visit Guidance for people who are fully vaccinated against COVID-19 | Mass.gov.
Is the Johnson & Johnson vaccine safe?
All COVID-19 vaccines are safe and highly effective; they provide high levels of protection against serious illness, hospitalization, and death. There is a risk of rare but serious conditions involving blood clots and low platelets, or Guillain Barré syndrome (where the body’s immune system damages nerve cells, causing muscle weakness and sometimes paralysis), in people after receiving the J&J COVID-19 Vaccine. The chance of either of these happening is very low, and the benefits of vaccination outweigh these risks. Review the FDA’s Johnson & Johnson fact sheet for more information.
How do we know if the vaccine is safe?
It’s important to know that vaccines go through more testing than any other pharmaceuticals. First, small groups of people receive the trial vaccine. Next, vaccine is given to people with certain characteristics (e.g., age, race, and physical health). Then, vaccine is given to tens of thousands of people and tested for effectiveness and safety.
After that, the CDC’s Advisory Committee on Immunization Practices (ACIP) looks at the data to see whether the vaccine works and is safe. They give advice to the United States Food and Drug Administration (FDA). The FDA looks at the data and the advice from the ACIP and decides whether to approve the vaccine. The vaccine is only approved after all of these steps are done, and the experts are sure that it works and is safe.
Visit Ensuring the Safety of COVID-19 Vaccines in the United States | CDC for more information.
How is it safe if it happened so fast?
The timeline to develop a COVID-19 vaccine was sped up but never cut corners on safety. Here is how:
- We already had helpful information: The COVID-19 virus is a part of a coronavirus family that has been studied for a long time. Experts learned important information from other coronavirus outbreaks that helped them to develop the COVID-19 vaccine, so we weren’t starting from scratch.
- Governments funded vaccine research: The United States and other governments invested a lot of money to support vaccine companies with their work. Working together with other countries also helped researchers move quickly.
- A lot of people participated in clinical trials: Many people wanted to help by being in the vaccine studies. Companies didn’t need to spend time finding volunteers.
- Manufacturing happened at the same time as safety studies: Vaccine companies were able to make and store doses of vaccine at the same time as studies (called clinical trials) were happening to show that the vaccines were safe and effective. This meant vaccines were ready to be distributed once they were approved.
How is it safe if we don’t know the long-term side effects?
The Pfizer and Moderna COVID-19 vaccines are what experts call messenger RNA vaccines, or mRNA vaccines for short. The Janssen (Johnson & Johnson) vaccine is called a viral vector vaccine. Both types of vaccines have been studied in animal and human trials for years. On the other hand, COVID-19 has only been around for about a year and the long-term side effects of COVID-19 infection are mostly unknown and may be serious. Therefore, getting vaccinated is the best choice for long-term health and safety.
Experts will continue to track COVID-19 vaccine side effects. People in clinical trials will be tracked for 2 years. Other people who get the vaccine can use a tool called v-safe on their smartphones to quickly tell the CDC if you have any side effects after getting the COVID-19 vaccine. V-safe users can share information for up to one year after their vaccine. Learn more at cdc.gov/vsafe.
Do the COVID-19 vaccines have any side effects?
Some people may have side effects after being vaccinated, which are normal signs that your body is building protection. These side effects may affect your ability to do daily activities, but they should go away in a few days. The most common side effects are minor and include tiredness, headache, pain at the injection site, muscle and/or joint pain, chills, nausea and/or vomiting, and fever.
Can a COVID-19 vaccine make me sick with COVID-19?
No. The Pfizer, Moderna, and Janssen (Johnson & Johnson) vaccines do not contain the live virus that causes COVID-19. This means that a COVID-19 vaccine cannot make you sick with COVID-19. (source: Facts about COVID-19 Vaccines (cdc.gov). Therefore, if you test positive for COVID-19, even if you have gotten the vaccine, you would need to isolate.
Should someone with a history of allergies get the COVID-19 vaccine?
You should not get the Pfizer, Moderna or Janssen (Johnson & Johnson) COVID-19 vaccines if you have a history of severe allergic reaction (also called anaphylaxis) to any ingredient in the vaccine. If you have a history of a severe allergic reaction to something else that’s not in the vaccine, discuss with your health care provider before receiving the vaccine.
Although there is a small chance that the COVID-19 vaccines could cause a severe allergic reaction, this would usually happen within a few minutes to one hour after getting the vaccine. Everyone, even if they don’t have allergies, is monitored for at least 15 minutes after getting a COVID-19 vaccine.
What are the ingredients in the vaccine?
The vaccines do not contain eggs, gelatin, preservatives, or latex. COVID-19 vaccine fact sheets for recipients and caregivers list the ingredients of each vaccine on pages 2-3: Comirnaty/Pfizer, Moderna, and Johnson & Johnson (Janssen).
Yes. The CDC recommends COVID-19 vaccination for people trying to get pregnant now, or who might become pregnant in the future. There is no evidence that antibodies made following COVID-19 vaccination or that vaccine ingredients will cause any problems with becoming pregnant now or in the future. In fact, there is no evidence that any vaccines, including COVID-19 vaccines, cause fertility problems in women or men. Learn more at COVID-19 Vaccines for People Who Would Like to Have a Baby | CDC.
Can someone who is pregnant or breastfeeding get a COVID-19 vaccine?
Yes. The CDC and American College of Obstetricians and Gynecologists recommend COVID-19 vaccination for people who are pregnant or breastfeeding. COVID-19 infection during pregnancy increases the risk of severe illness and preterm birth. Evidence about the safety and effectiveness of COVID-19 vaccination during pregnancy has been growing. Data suggest that the benefits of receiving a COVID-19 vaccine outweigh any known or possible risks of vaccination during pregnancy.
Getting vaccinated is a personal choice for people who are pregnant or breastfeeding. If you have questions, discuss vaccination with your healthcare provider.
Are the COVID-19 vaccines safe for children?
Yes. The CDC recommends everyone ages 5 and older get a COVID-19 vaccine. Scientists have conducted clinical trials with about 3,000 children and determined it to be safe and effective. At this time, the Pfizer vaccine is authorized for people ages 5 and older (and has given full approval for people ages 16 and older). The Moderna and Janssen (Johnson & Johnson) vaccines are authorized for people ages 18 and older. Learn more:
Will a COVID-19 vaccine change my DNA?
No. The COVID-19 vaccines do not change or interact with your DNA in any way.
Vaccines teach our immune system how to fight against a specific virus. They work with the body’s natural defenses to safely develop immunity to disease. In order to do its job, the COVID-19 vaccine doesn’t need to go inside the nucleus of the cell, which is where our DNA is kept. This means the vaccine never interacts with our DNA in any way and has no way to change it.
At the end of the process, our bodies have learned how to protect against future infection. That immune response and making antibodies is what protects us from getting infected if the real virus enters our bodies. (source: Facts about COVID-19 Vaccines (cdc.gov)
Who were the vaccines tested on?
The safety of the Pfizer COVID-19 vaccine was evaluated in people 16 years of age and older, most from the United States. Overall, 50.6% of participants were male and 49.4% were female, 83.1% were White, 9.1% were Black or African American, 28.0% were Hispanic or Latino, 4.3% were Asian, and 0.5% were American Indian or Alaska Native. Additional studies were done with 2,260 adolescents ages 12-15 and 3,000 children ages 5-11.
The safety of the Moderna COVID-19 vaccine was evaluated in people 18 years of age and older in the United States. Overall, 52.7% of participants were male, 47.3% were female, 79.2% were White, 10.2% were Black or African American, 20.5% were Hispanic or Latino, 4.6% were Asian, 0.8% were American Indian or Alaska Native, 0.2% were Native Hawaiian or Pacific Islander, 2.1% were Other, and 2.1% were Multiracial.
The safety of the Janssen (Johnson & Johnson) vaccine was evaluated in people 18 years of age and older in the U.S., Brazil, South Africa, Colombia, Argentina, Peru, Chile, and Mexico. Overall, 45% of participants were female, 55% were male, 58.7% were White, 19.4% were Black or African American, 45.3% were Hispanic or Latino, 3.3% were Asian, 9.5% were American Indian/Alaska Native 0.2% were Native Hawaiian or other Pacific Islander, 5.6% were from multiple racial groups and 1.4% were unknown races.
