Pfizer Inc. said that, in children aged 5 through 11, the COVID-19 vaccine it co-developed with Biontech SE showed 90.7% efficacy against all variants of concern following two doses. The data were included in briefing documents filed ahead of a full discussion at the FDA’s Vaccines and Related Biological Products advisory committee meeting set for Oct. 26.
Despite some concerns from a few members, the Advisory Committee on Immunization Practices unanimously approved recommendations to the CDC that boosters be made available to those wanting them. The advisory committee recommended that a single COVID-19 vaccine booster dose be given six months or more after completing an mRNA primary series in the same risk group for whom the CDC recommended a booster dose of Pfizer Inc-Biontech SA’s vaccine. The CDC presented data to the committee that the single mRNA COVID-19 vaccine dose be given to those age 65 and older, for those at least 18 years old and reside in long-term-care settings, and also for those ages 50 to 60 with certain underlying medical conditions.
Given the FDA’s Vaccines and Related Biological Products Advisory Committee’s unanimous vote last month to recommend use of a booster dose of the Pfizer Inc.-Biontech SE COVID-19 vaccine in certain high-risk groups, it came as no surprise when the committee again voted unanimously Oct. 14 for a mirror use of Moderna Inc.’s proposed booster.
Should Johnson & Johnson’s (J&J) COVID-19 vaccine be a two-dose series? While not directly asked, that question almost lurks between the lines of the FDA’s briefing document for the Oct. 15 meeting of its Vaccines and Related Biological Products Advisory Committee. The document referred to J&J’s proposed second dose as a “booster,” but the FDA isn’t asking the committee the questions it posed for the Moderna Inc. and Pfizer Inc.-Biontech SE boosters. Instead, it is inviting VRBPAC to advise on whether the second J&J dose should be administered two months or six months following the first shot.
Although the need for COVID-19 boosters remains a tense debate among policymakers and scientific experts worldwide, the U.S. FDA is basing its Oct. 14-15 Vaccines and Related Biologics Products Advisory Committee meeting on the premise that vaccine boosters are needed.
LONDON – The EMA has changed its stance on booster doses of the Pfizer Inc./Biontech SE COVID-19 vaccine and said they “may now be considered” at least six months after the second dose for people ages 18 and over.
Now that Pfizer Inc.-Biontech SE has submitted initial phase II/III study data to the FDA bolstering the case for an emergency use authorization (EUA) for its COVID-19 vaccine to children ages 5 through 11 years, the competition, including Moderna Inc., Novavax Inc. and Sanofi SA, falls further behind.
Pfizer Inc. and Biontech SE have announced new data that could pave the way for childhood COVID-19 vaccine programs, with findings of a trial showing their shot is safe and effective in children of 5 to 12 years of age.
The FDA’s Vaccines and Related Biological Products Advisory Committee rejected an sBLA for a third, booster dose of the COVID-19 vaccine Comirnaty from Pfizer Inc.-Biontech SE for ages 16 and over, then unanimously approved a recommendation for those ages 65 and older along with individuals at high risk of severe COVID-19 to get the booster.
As members of the White House COVID-19 Response Team talk about COVID-19 boosters as if they are a fait accompli for Americans even before the FDA completes its evaluation of the data, the controversy continues to roil around the need for another vaccine dose.
