The Hill: Pfizer To Seek FDA Authorization For Booster Of COVID-19 Vaccine
"As seen in real world data released from the Israel Ministry of Health, vaccine efficacy in preventing both infection and symptomatic disease has declined six months post-vaccination, although efficacy in preventing serious illnesses remains high," Pfizer said. "Based on the totality of the data they have to date, Pfizer and BioNTech believe that a third dose may be beneficial within 6 to 12 months following the second dose to maintain highest levels of protection," the companies said.

AP: Pfizer To Seek OK For 3rd Vaccine Dose; Shots Still Protect
Two doses of most vaccines are critical to develop high levels of virus-fighting antibodies against all versions of the coronavirus, not just the delta variant -- and most of the world still is desperate to get those initial protective doses as the pandemic continues to rage. But antibodies naturally wane over time, so studies also are underway to tell if and when boosters might be needed. On Thursday, Pfizer’s Dr. Mikael Dolsten told The Associated Press that early data from the company’s booster study suggests people’s antibody levels jump five- to 10-fold after a third dose, compared to their second dose months earlier.

The companies said although they believe a third shot of their current two-dose vaccine has the potential to preserve the “highest levels” of protection against all currently known variants, including delta, they are “remaining vigilant” and developing an updated version of the vaccine.
