FDA LEADERS: ANNUAL COVID VACCINE UPDATE LIKELY NEEDED — FDA and its advisers will likely need to consider yearly updates to the Covid-19 vaccine, Commissioner Robert Califf, top vaccine regulator Peter Marks and principal deputy commissioner Janet Woodcock wrote Monday in JAMA. “It is time to accept that the presence of SARS-CoV-2, the virus that causes COVID-19, is the new normal,” Marks, Woodcock and Califf wrote. “It will likely circulate globally for the foreseeable future, taking its place alongside other common respiratory viruses such as influenza.” The U.S. must decide by early summer whether vaccines should be updated and who should be eligible for additional booster shots — and consider administering Covid-19 doses alongside the flu vaccines to “protect susceptible individuals against hospitalization and death.” Because of the long manufacturing timeline for Covid-19 vaccines, composition decisions need to be settled by June. FDA advisers are scheduled to meet June 28 on the topic. “To date, the original, or prototype, vaccine composition deployed has been reasonably good at protecting against severe outcomes from COVID-19,” the regulators wrote. “However, a greater depth and duration of protection might be achieved with a vaccine covering currently circulating variants.” FDA RELEASES ‘TENTATIVE’ ADVISORY MEETING SCHEDULE — FDA released its “tentative” June meeting schedule — with emphasis on the word tentative — on Friday for its vaccine advisory committee. The lineup will cover several outstanding Covid-related items, including the strain composition for the vaccines come fall and Novavax's emergency use authorization request for an adult Covid vaccine. But the dates set aside for kids’ Covid shots — June 8, 21 and 22 — are drawing the most attention since they mean the earliest a vaccine will be available for children under 5 is midmonth. Still, Moderna has said it will likely take until later this week to complete its data submission to FDA, and that’s when agency reviewers can begin tackling the application in earnest. INGLESBY DEPARTING BIDEN ADMIN — Tom Inglesby, the federal official in charge of the Biden administration’s Covid-19 testing efforts, has returned to his full-time job as director of the Johns Hopkins Center for Health Security, David reports. He will continue to serve as an adviser to the White House Covid response team until early June, according to a source familiar with the process granted anonymity to discuss the personnel timeline. The White House is working to hire a new testing lead and aims to have the individual installed and working before Inglesby fully departs. PFIZER: PAXLOVID FAILS AS PREVENTATIVE POST-EXPOSURE — Paxlovid, Pfizer’s Covid antiviral pill regimen, failed to adequately prevent people living in the same households as someone with Covid-19 from contracting the disease in a clinical trial, Pfizer said late Friday. The company studied 2,957 adults who had negative rapid test results and no symptoms within 96 hours of being exposed to Covid-positive household contacts. The exposed subjects took five- or 10-day courses of Paxlovid or 10 days of a placebo. “While we are disappointed in the outcome of this particular study, these results do not impact the strong efficacy and safety data we’ve observed in our earlier trial for the treatment of COVID-19 patients at high risk of developing severe illness, and we are pleased to see the growing global use of PAXLOVID in that population,” Pfizer Chairman and CEO Albert Bourla said. Paxlovid and the VP: Vice President Kamala Harris’ Paxlovid prescription drew attention last week to a pandemic tool that had largely been overshadowed by vaccine messaging and supply woes. It also raised questions among some doctors about whether the drug can and should be prescribed to asymptomatic Covid patients, based on how the EUA is written. Do you have thoughts?
