On condition that Moderna’s vaccine seems to nonetheless strongly shield towards extreme illness, at the very least some committee members are anticipated to balk at recommending a 3rd dose. “Possibly it gained’t be a slam dunk,” stated Dr. Peter J. Hotez, a vaccine knowledgeable on the Baylor Faculty of Medication, of the panel’s vote. “Possibly we must always wait slightly bit longer on Moderna, let it drop off extra first earlier than we enhance.”
One of many first shows Thursday will come from Israeli well being officers, who will focus on outcomes of their booster marketing campaign utilizing Pfizer-BioNTech’s vaccine.
