Dr. Rochelle Walensky, director of the US Centers for Disease Control and Prevention, signed off Thursday on the recommendation of the agency's independent vaccine advisers in favor of updated Covid-19 vaccine boosters from Pfizer/BioNTech and Moderna. The CDC's Advisory Committee on Immunization Practices voted 13 to 1 earlier in the day to recommend updated mRNA boosters for Americans this fall.

Walensky's decision means the shots could be available by Friday, according to pharmaceutical manufacturers, which began shipping the new doses after the US Food and Drug Administration authorized them Wednesday.
"The updated COVID-19 boosters are formulated to better protect against the most recently circulating COVID-19 variant," Walensky said in a statement. "They can help restore protection that has waned since previous vaccination and were designed to provide broader protection against newer variants. This recommendation followed a comprehensive scientific evaluation and robust scientific discussion. If you are eligible, there is no bad time to get your COVID-19 booster and I strongly encourage you to receive it." The updated boosters have instructions that tell our cells to make antibodies against two strains of the virus that causes Covid-19: the original strain and the BA.4 and BA.5 Omicron subvariants, which share the same spike.
Pfizer/BioNTech's updated vaccine is a 30-microgram dose authorized for people 12 and older. Moderna's updated vaccine is a 50-microgram dose authorized for people 18 and older.
Pfizer is saying they should be available by next week, I image Moderna is the same.
