If you were exposed to COVID-19, take three home tests instead of two to make sure you’re not infected, according to new U.S. recommendations released Thursday. Previously, the Food and Drug Administration had advised taking two rapid antigen tests over two or three days to rule out infection. But the agency says new studies suggest that protocol can miss too many infections, and could result in people spreading the coronavirus to others, especially if they don’t develop symptoms.

Countries in the middle or just past the peak of a surge driven by the BA.5 omicron subvariant, such as the U.S., likely won't experience a subsequent wave from BA.2.75, another omicron relative, some experts predict. "We're coming to a point where these variants are sort of competing with each other and they're almost equivalent," Dr. Shahid Jameel, a virologist at the University of Oxford in the U.K., told Nature in an Aug. 10 report.

The antiviral drug that treats COVID-19, Paxlovid, must be taken within five days after symptoms begin. To expand quick access to the medication, the U.S. Food and Drug Administration revised the Emergency Use Authorization for Paxlovid in July to authorize state-licensed pharmacists to directly prescribe it. “We were seeing some really low uptake and even within the pharmacy we were seeing just the medication sit on shelves because prescriptions weren't coming in,” said Richard Dang, president of the California Pharmacists Association.

About 135 million more doses of Johnson & Johnson’s COVID-19 vaccine from a troubled Baltimore factory will have to be destroyed due to quality problems, Congressional panel leaders said Thursday. The announcement follows a report in May that detailed how more than 400 million vaccine doses made at an Emergent BioSolutions plant had to be trashed. The doses more recently slated for destruction were made between August 2021 and February, the House members said. (8/11)

Although over 61 million people, over the age of 50, are eligible to receive their second COVID-19 booster shot, just a third have actually done so, according to data from the Centers for Disease Control and Prevention. Similarly, less than half of Americans, over the age of 5, who are eligible to receive their first booster have received their supplemental shot. (Mitropoulos, 8/12)
