You received the Johnson & Johnson (Janssen) vaccine
Important Information for those receiving the COVID-19 vaccine
Thank you for receiving the COVID-19 vaccine. You are an important part of our effort to stop the spread and keep our communities safe.
You’re not fully vaccinated yet!
You will not be fully vaccinated until two weeks after you receive the Johnson and Johnson vaccine. Until then, you can still contract and spread COVID-19. Continue to practice habits to reduce the spread.
- Wash your hands
- Wear a mask
- Keep your distance
- Avoid groups
Not everyone will be vaccinated when you are. And while we know it dramatically reduces symptoms, we are still learning about the vaccine’s protection against COVID-19 in real-life conditions.
Many people experience minor side effects, but major side effects are rare
Serious side effects from vaccines, including the COVID-19 vaccine, are rare. The most common side effects are minor and include
- Pain at injection site
- Muscle pain and/or joint pain
These side effects can last several days but are not cause for alarm. If pain at the injection site persists or you are worried, contact your doctor. If you do not have a primary care provider or wish to report any side effects to the CDC, visit cdc.gov/vsafe
Get medical care right away if you develop any of the symptoms below within three weeks after receiving the Johnson & Johnson COVID-19 Vaccine:
- Severe headache or blurred vision
