Members shared widespread confusion about whether to receive a third full dose versus a half-dose booster of the COVID-19 vaccine while taking Hydroxyurea, with advice varying significantly between hematologists, MPN specialists, pharmacists, and primary care doctors. Several members clarified key distinctions, noting that the Pfizer booster and third dose are identical, while the Moderna booster is half the strength of a full third dose, and that immunocompromised individuals may qualify for a full third dose at least 28 days after their second shot. A recurring theme was the frustration of conflicting medical guidance and the importance of consulting an MPN specialist for personalized advice, with most members ultimately following their specialist's recommendations while acknowledging the evolving nature of COVID vaccine protocols.
