The FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) voted 17-0, with one abstention, that the benefits of Pfizer Inc.-Biontech SE pediatric formulation of its two-dose COVID-19 vaccine outweigh its risks for children ages 5 through 11. Many of those votes came with caveats, as the VRBPAC members struggled with the unknowns of the vaccine and the fear that schools would mandate its use, even though it would still be considered experimental if the FDA grants it an emergency use authorization.
LONDON – A U.K. study following up 32.5 million people for 28 days after their first dose of a COVID-19 vaccine has shown an increased risk of hemorrhagic stroke after receiving the Pfizer Inc./Biontech SE product, and confirmed case reports of an increased risk of developing Guillain-Barré syndrome after the Astrazeneca plc vaccine.
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.
LONDON – Valneva SA’s COVID-19 vaccine, VLA-2001, prompted a stronger immune response with fewer side effects than Astrazeneca plc’s product, according to headline data from the phase III trial. Shares in Valneva (NASDAQ:VALN) shot up by nearly 40% to close Oct. 18 at $39.21 when the data were announced, partly repairing the damage on Sept. 13 when the U.K. government cancelled a $1.65 billion contract with the French vaccines specialist for 100 million doses.
LONDON – The EMA recommended approval of Apellis Pharmaceuticals Inc.’s C3 complement inhibitor, Aspaveli (pegcetacoplan), to treat paroxysmal nocturnal hemoglobinuria, but has diverged from the FDA, excluding treatment-naïve patients adding its use should be restricted to those who have failed to respond to C5 inhibitor drugs.
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.
The U.K.’s Medicines and Healthcare Products Regulatory Agency (MHRA) joined the JAK inhibitor pile-on Oct. 6 with new measures to reduce the risk of major heart problems and malignancies in people taking Pfizer Inc.’s Xeljanz (tofacitinib).
