Yesterday, the White House announced it would recommend people get a booster shot of the Covid-19 vaccine eight months after their second shot. So how did they reach that conclusion?
in Monday night’s article, between its publication and the HHS statement issued Wednesday morning, no such data were made publicly available.
While members of the Covid-19 Task Force used Wednesday’s briefing to highlight some of the newly published data — making a clear case for why now is the time to recommend Covid vaccine boosters — a CDC press officer stressed that data monitoring and evaluation has been ongoing.
Finally, the remaining study looked at vaccine effectiveness against new Covid infections among nursing home residents, finding that it dropped from 75 percent in March to 53 percent in August. “Taken together,” Walensky said, “these data confirm that while protection against infection may decrease over time, protection against severe disease and hospitalization is currently holding up pretty well.
At Wednesday’s briefing, Fauci shared some up-to-date immunological data supporting a booster mRNA immunization. In short, the Covid-19 antibodies we acquire through the vaccine decline over time. This isn’t ideal, considering that higher antibody levels are associated with higher vaccine efficacy, and that they may be needed to offer protection against the Delta variant.
