You'll need to clear up confusion about COVID-19 vaccines.
Terminology. Clarify that "boosters" aim to maintain protection after an adequate initial immune response. Third or "additional doses" are for those who likely had an INadequate response to the initial series.
Also point out that boosters are given at least 6 months after a completed series...but additional doses are given earlier, at least 4 weeks after a completed series.
