Dr. Anthony Fauci, the top medical adviser to President Biden, defended the administration’s decision to recommend coronavirus vaccine booster shots and said that three doses of an mRNA vaccine, not two, would be the new standard of full vaccination.
I would not at all be surprised that the adequate, full regimen for vaccination will likely be three doses,” Fauci said during a Thursday briefing of the White House coronavirus response team, though he noted that regulators would have to ultimately make that determination.
Fauci presented data from Israel that showed waning immunity to the virus after about eights months that he said “supported the rationale for COVID-19 booster shots.”
After the more transmissible Delta variant arrived in Israel in early summer, the number of positive coronavirus cases and severe COVID-related illnesses rose among vaccinated individuals between June and August. By then, many Israelis had been vaccinated for more than half a year, a testament to the speed with which the small, technologically advanced nation had conducted its inoculation campaign.
