2nd COVID-19 vaccine set for OK in US with panel endorsement
WASHINGTON >> A government advisory panel endorsed a second COVID-19 vaccine Thursday, paving the way for the shot to be added to the U. S. vaccination campaign.
The Food and Drug Administration is expected to follow the recommendation for the vaccine from Moderna and the National Institutes of Health. The FDA advisers, in a 20- 0 vote, agreed the benefits of the vaccine outweighed the risks for those 18 years old and up.
The FDA’s green light for emergency use is expected quickly. Moderna would then begin shipping millions of doses, earmarked for health workers and nursing home residents, to boost the largest vaccination effort in U. S. history.
The campaign kicked off earlier this week with the first vaccine OK’d in the U. S., developed by Pfizer and BioN Tech. Moderna’s shot showed similarly strong protection, providing 94% protection against COVID-19 in the company’s ongoing study of 30,000 people.
After seven hours of debate over technical details of the company’s study and follow-up plans, nearly all panelists backed making the vaccine available to help fight the pandemic. One panel member abstained.
“The evidence that has been studied in great detail on this vaccine highly outweighs any of the issues we’ve seen,” said Dr. Hayley Gans of Stanford University Medical Center.
A second vaccine is urgently needed as coronavirus infections, hospitalizations and deaths climb to new highs ahead of the holidays. The U.S. leads the world in virus totals, with more than 1.6 million confirmed cases and nearly 309,000 reported deaths.
Moderna’s vaccine uses the same groundbreaking technology as Pfizer-BioNTech’s shot. Most traditional vaccines use dead or weakened virus, but both of the new vaccines use snippets of COVID-19’s genetic code to train the immune system to detect and fight the virus. Both require two doses, several weeks apart.
Thursday’s review came days after reports of apparent allergic reactions to the Pfizer-BioNTech vaccine in two Alaska health workers. One person had a severe reaction, including shortness of breath, the other had less serious side effects, including lightheadedness.
While the two vaccines use the same technology, they’re not identical, cautioned Moderna chief medical officer Dr. Tal Zaks. In particular, some of the lipids, or fats, used to coat the two vaccines are different.
“I would not necessarily assume” that any reactions would be the same, he said.
