The FDA issued a June 10 warning letter to Innova Medical Group Inc. in connection with the company’s rapid antigen tests for the SARS-CoV-2 virus, an action that accompanies a class I recall and a safety communication.

Researchers at the University of Washington reported in the May 31, 2021, issue of Nature Medicine that artificial intelligence (AI) algorithms meant to recognize COVID-19 infections based on chest X-rays picked up on confounders, selecting “shortcuts” such as patient age or positioning in the X-ray as a basis for their predictions.

The FDA has authorized two batches of Johnson & Johnson’s COVID-19 vaccine from a troubled Emergent Biosolutions Inc. manufacturing facility to be made available under emergency use authorization (EUA) while determining that several other batches were unsuitable for use. While the FDA would not confirm the number of unsuitable batches, the newly authorized batches, however, can be used in the U.S. or exported.

The good of the many versus the good of the individual is the age-old question that faced the FDA’s Vaccines and Related Products Advisory Committee (VRPAC) June 10 as it considered the risk-benefit issues of COVID-19 vaccines in children. Panelist Cody Meissner, director of pediatric infectious disease at Tufts Medical Center, said while he believes a vaccine is needed for children, he wants to know that the safety of the vaccine is greater than the risk of hospitalization for people younger than 18.
