In general, you are considered “fully vaccinated” and up-to-date with COVID-19 guidelines after you have received the recommended doses of the updated vaccine for your age, health status, and vaccine history. Depending on these factors, being “fully vaccinated” can look different for each person. As science and the virus evolve, so does our understanding of what it means to be “fully vaccinated”. Researchers continue to watch closely for signs of waning vaccine immunity over time, monitor new variants of the virus, and track how data differs across groups.
If you are not sure if you are “fully vaccinated” consult with a healthcare provider about completing the primary vaccine series, getting at least one updated Pfizer-BioNTech or Moderna dose, or getting the updated Novavax series.
