Most people do not have serious problems after being vaccinated. Live virus vaccines are known to cause more systemic side effects. This is not a live virus vaccine. The Pfizer and Moderna vaccines are both mRNA vaccines. However, your arm may be sore, red, or warm to the touch. These symptoms usually go away on their own <72 hours. Some people report getting a headache or fever when getting a vaccine. These side effects are a sign that your immune system is doing exactly what it is supposed to do. It is working and building up protection for the disease.

It typically takes a few weeks for the body to build protection against the virus following vaccination. The CDC defines an individual as fully vaccinated if they have met the following:
- 2 weeks after their second dose in a 2-dose series, such as the Pfizer or Moderna vaccines, or
- 2 weeks after a single-dose vaccine, such as Johnson & Johnson’s Janssen vaccine
If you don’t meet these requirements, you are NOT fully vaccinated. If you are NOT fully vaccinated then yes, you still need to quarantine. Keep taking all precautions until you are fully vaccinated.
If you ARE fully vaccinated the CDC recommends the following:
If you’ve been around someone who has COVID-19, you do not need to stay away from others or get tested unless you have symptoms.
- However, if you live in a group setting (like a correctional or detention facility or group home) and are around someone who has COVID-19, you should still stay away from others for 14 days and get tested, even if you don’t have symptoms.
Severe reactions to any vaccine are very rare. Most people experience only mild side effects, such as a sore arm or mild headache.
After you receive your vaccine, you are required to remain on site for 15-30 minutes for observation. When severe allergic reactions do occur, they tend to happen in the minutes following your injection. Vaccination sites have trained medical personnel on site to help you if you should experience any level of allergic reaction.
If you should experience a reaction after you return home and do not have medical insurance, you can seek care from a local community health center or hospital, or a Federally Qualified Healthcare Center.
