The Food and Drug Administration has asked states to temporarily stop using Johnson & Johnson’s one-shot COVID-19 vaccine “out of an abundance of caution.” The move comes after six women in the U.S. developed a rare blood clotting disorder, out of the nearly 7 million people in the country who have received the vaccine so far. The Centers for Disease Control and Prevention’s outside advisory committee has called an emergency meeting for Wednesday. The CDC also said supply of two other vaccines approved for emergency use in the U.S. (Pfizer and Moderna) are sufficient to meet demand.
- The CDC urged Michigan — where 16 of the 17 worst outbreaks of the virus are occurring in the U.S. — to enact new shutdowns.
- Low efficacy rates among Chinese vaccines are raising concerns about rollouts in countries from Brazil to Hungary.
- A monoclonal antibody drug has shown promise in fighting COVID-19 in early clinical trial results, said drug maker Regeneron on Monday.
- A massive study on college campuses aims to find out if Moderna’s vaccine prevents transmission of the virus.
