With Valneva SE’s accelerated approval from the U.S. FDA for chikungunya vaccine Ixchiq, attention turned to the February 2024 meeting of the Advisory Committee on Immunization Practices (ACIP), which will vote on the product. A single-dose, live-attenuated vaccine, Ixchiq is designed to prevent disease caused by the virus in people 18 and older who are at increased risk of exposure to the bug.
Instead of the bivalent COVID-19 vaccines comprising both the original and omicron BA.4/BA.5 SARS-CoV-2 strains that have been in use in the U.S. since April, the CDC’s Advisory Committee for Immunization Practices voted 13-1 Sept. 12 to recommend the universal use of updated monovalent XBB-containing COVID-19 vaccines as authorized or approved by the FDA.
In the hope of preventing thousands of hospitalizations and deaths over the next few months, the U.S. CDC’s Advisory Committee on Immunization Practice (ACIP) voted 13-1 Sept. 1 to recommend the use of Moderna Inc.’s and Pfizer Inc.-Biontech SE’s updated vaccines that contain components of both the original SARS-CoV-2 virus and the omicron BA.4/5 subvariants as boosters.
Right on cue, the U.S. FDA authorized bivalent COVID-19 vaccines from Moderna Inc. and Pfizer Inc.-Biontech SE to be given as boosters at least two months following a primary vaccine series or a previous booster. “These updated boosters present us with an opportunity to get ahead of the next wave of COVID-19,” FDA Commissioner Robert Califf said, following the Aug. 31 announcement.
Although it’s a latecomer to the COVID-19 pandemic in the U.S., there is a wedge of opportunity for Novavax Inc.’s adjuvanted protein-based vaccine among the 10% of the U.S. adult population that has yet to get a first jab.
Instead of “Mother, may I” for COVID-19 vaccines for children 6 months through 5 years of age, the U.S. CDC is saying the correct response is “I should.” That was the recommendation June 18 from the CDC’s Advisory Committee on Immunization Practices. CDC Director Rochelle Walensky wasted no time in endorsing the recommendation, which came just a day after the FDA authorized the vaccines from Moderna Inc. and Pfizer Inc.-Biontech SE for babies, toddlers and preschoolers.
More than two years into the COVID-19 pandemic and nearly 18 months since a vaccine was first available for adults, the U.S. is on the cusp of having vaccines available to the youngest Americans.
Two days after the U.S. FDA authorized a single booster dose of the Pfizer Inc.-Biontech SE COVID-19 vaccine for children ages 5 to 11, the U.S. CDC’s Advisory Committee on Immunization Practices (ACIP) gave its blessing to the third dose.
The U.S. FDA’s efficacy bar for COVID-19 vaccines for the youngest children may be lower than the 50% required for the adult vaccines, according to Peter Marks, director of the agency’s Center for Biologics Evaluation and Research.<
The U.S. COVID-19 vaccine program is at risk of “booster fatigue,” which will undermine public confidence in the vaccines, several members of the CDC’s Advisory Committee on Immunization Practices (ACIP) said April 20 as they met to discuss the future of the vaccines. Rather than relying on boosters, “we need to use our expertise to advocate for something that’s better,” something that resolves the ill effects of COVID-19, whether it’s mild or severe, said Lynn Bahta, an immunization program clinical consultant for the Minnesota Department of Health.
