COVID-19 Vaccination Information

If you receive a Pfizer-BioNTech or Moderna COVID-19 vaccine, you will need 2 shots to get the most protection. If you receive your second shot of COVID-19 vaccine later than recommended, you do NOT have to restart the vaccine series.
If you received a Pfizer-BioNTech or Moderna COVID-19 vaccine, you should get the same product for your second shot. You should get your second shot even if you have side effects after the first shot, unless a vaccination provider or your doctor tells you not to get it.
The timing between your first and second shots depends on which vaccine you received. If you received the Pfizer-BioNTech COVID-19 Vaccine, you should get your second shot 3 weeks (or 21 days) after your first. If you received the Moderna COVID-19 Vaccine, you should get your second shot 4 weeks (or 28 days) after your first.
You should get your second shot as close to the recommended 3-week or 4-week interval as possible. However, your second dose may be given up to 6 weeks (42 days) after the first dose, if necessary. You should not get the second dose early.
Planning for your second shot is important. If you need help scheduling your vaccination appointment for your second shot, contact the location that set up your first appointment. If you are having trouble or have questions about using a vaccination management or scheduling system, reach out to the organization that enrolled you in the system. This may be your state or local health department, employer, or vaccination provider.​ Scheduling an appointment for your second shot at the time you get your first shot is recommended, but not required.
If you need to get your second shot in a location that is different from where you received your first shot (for example, if you moved to a different state or attend school in a different state), there are several ways you can find a vaccine provider for your second dose.

COVID-19 Vaccines for Moderately to Severely Immunocompromised People: updated 8/18/21:

What You Need to Know

  • People who are moderately to severely immunocompromised are especially vulnerable to COVID-19 because they are more at risk of serious, prolonged illness.
  • People with moderately to severely compromised immune systems may not build the same level of immunity to 2-dose vaccine series compared to people who are not immunocompromised.
  • People who have compromised immune systems may benefit from an additional dose to make sure they have enough protection against COVID-19.
  • CDC recommends people who are moderately to severely immunocompromised should receive an additional dose of mRNA COVID-19 vaccine after the initial 2 doses.
  • This additional dose intended to improve immunocompromised people’s response to their initial vaccine series is not the same as a booster dose, given to people when the immune response to a primary vaccine series is likely to have waned over time.
  • CDC does not recommend additional doses or booster shots for any other population at this time.
  • CDC recommends that people with moderately to severely compromised immune systems receive an additional dose of mRNA COVID-19 vaccine at least 28 days after a second dose of Pfizer-BioNTech COVID-19 vaccine or Moderna COVID-19 vaccine.

Search for your COVID-19 vaccine record at the Virginia Department of Health‘s Vaccination Record Request Portal. Once you have accessed your record, it can be saved, printed, or downloaded as a PDF.

Your vaccination record will only show COVID-19 immunizations.
If you received vaccines out of state or if a federal agency administered your vaccines, they will not show up in this self-serve portal.
This portal is not a “vaccine passport” but serves as a way to prove you were vaccinated for COVID-19.
