Research Roundup: Paxlovid concerns, new TB drug regimen, COVID-19 booster approvals
In this regular feature on Breakthroughs, we highlight some of the most interesting reads in global health research from the past week.
Experts are increasingly concerned about connections between Paxlovid, Pfizer’s COVID-19 antiviral drug, and COVID rebound in patients who complete the five-day regimen, especially as Paxlovid use has grown dramatically in recent months. The US Food and Drug Administration (FDA) has asked Pfizer to investigate whether a second course will prevent rebound. A large study previously showed that Paxlovid significantly reduced hospitalizations and deaths in those 65 years and older, but uncertainty remains over the drug’s effectiveness in younger people as well as the link between the drug and COVID rebound. Rebound has also been observed in people who have not taken Paxlovid as well.
On Wednesday, August 31, the FDA gave emergency use authorizations to Moderna and Pfizer-BioNTech’s Omicron-updated COVID-19 booster shots to be used as single-dose inoculations at least two months after the first booster vaccination. Both vaccines are aimed at targeting both the original COVID-19 and B.A.4 and B.A.4 Omicron subvariants. Whereas Moderna’s booster is approved for all adults 18 years and older, the Pfizer-BioNTech booster is approved for all people 12 years and older. The CDC endorsed the vaccines on Thursday, clearing the way for a quick rollout in the coming weeks.
