This is misleading.
In order to get a vaccine to Emergency Use Approval (EUA) it had to meet certain pre-determined endpoints.
Operation Warp Speed was innovative in many ways. Two of them were making every manufacturer use the SAME endpoints, determined the SAME way, and allowing early termination if there was a statistically significant difference in severe illness or death.
A study to address prevention of infection, or prevention of transmission, would need to go on for much longer, while the death toll climbs.
The question about preventing infection and preventing infectivity hasn’t been answered in the negative - it just can’t be answered at all, right now.
By contrast, the utility of the Pfizer and Moderna vaccines for the prevention of serious illness or death, at least over four months, is answered by the data in hand.
Yeah, its the same thing for contracting the disease. They STILL won't say (don't know) if you are effectively immune from future exposures after an initial exposure and effective immune response, but most likely you are.
It could be answered by testing all the participants for SARS-Cov2. They only tested if the participant had âÂÂsevere respiratory illnessâÂÂ. They did not test any of the 3000+ participants with symptoms that didnâÂÂt fall into that category. Those 3000 participants represent 10% of total participants. They also did not test for asymptomatic cases.
