FDA backs changing Covid booster shots to target most recent omicron subvariants
- Dr. Peter Marks, head of the FDA’s vaccine division, said manufacturers should update their shots to target omicron BA.4 and BA.5 in addition to the original strain of the virus that first emerged in Wuhan, China in 2019.
- The FDA has asked the companies to start clinical trials on these newer subvariants, Marks said.
- The vaccine makers are having trouble keeping up with the rapid evolution of the virus.
- Pfizer and Moderna developed their omicron shots to target the original version of the variant, BA.1., which caused the massive wave of infection over the winter.
