BOOSTER DOSES VS. ADDITIONAL DOSES (Yes, it is confusing....this should help explain the difference)

According to the CDC, sometimes people who are moderately to severely immunocompromised do not build enough (or any) protection when they first get a vaccination. When this happens, getting another dose of the vaccine can sometimes help them build more protection against the disease. This appears to be the case for some immunocompromised people and COVID-19 vaccines. CDC recommends moderately to severely immunocompromised people consider receiving an additional (third) dose of an mRNA COVID-19 vaccine (Pfizer-BioNTech or Moderna) at least 28 days after the completion of the initial 2-dose mRNA COVID-19 vaccine series. For information on additional doses for some immunocompromised individuals, please see the statement available here.

In contrast, a “booster dose” refers to another dose of a vaccine that is given to someone who built enough protection after being fully vaccinated, but then that protection decreased over time (this is called waning immunity).

CDC and FDA Lift Pause on the Johnson & Johnson Vaccine: Following a thorough safety review, the Centers for Disease Control and Prevention (CDC) and the U.S. Food and Drug Administration (FDA) have lifted their recommendation to pause the administration of the Johnson & Johnson/Janssen (J&J) COVID-19 vaccine on April 23, allowing for the use of the J&J vaccine to resume in the U.S. The CDC and FDA determined that the J&J vaccine’s known and potential benefits outweigh its known and potential risks. The two agencies will continue to monitor the safety of all COVID-19 vaccines. For more information about the J&J vaccine, visit the CDC website. If you have questions about any of the COVID-19 vaccines, you should speak with your healthcare provider.
