Food and Drug Administration Scientist On Tuesday, Moderna said the FDA did not meet all the criteria needed to support booster vaccines.
Around Yahoo! News, FDA scientists have released a new document showing the antibodies produced by Booster Shot of the Moderna vaccine. However, the difference in antibody levels before and after the booster shot was not large enough to justify the booster shot.
- In fact, those who were already showing high antibody levels in the first two-dose regimen showed no signs of elevated antibody levels.
- So, in a sense, Moderna shots may already be too strong to guarantee booster shots.
John MooreA professor of microbiology and immunology at Weill Cornell Medical College in New York said: Yahoo! News There are still many questions about Moderna booster shots and what the FDA wants from it.
- “Sure, there was a boost. Was it enough boost? Do you know? There is no standard amount of boost known to be needed, and it’s not clear how much boost happened in the study. is not.” Moore said.
- Moderna’s original double-dose regimen had two doses of 100 micrograms.
- For comparison, Pfizer’s first shot was two doses of 30 micrograms.
Half the dose of booster shots says it is likely to reduce the side effects of shots Bloomberg.. And that will allow Moderna to spread booster shots more widely around the world.
NS Food and Drug Administration Centers for Disease Control and Prevention approved Pfizer booster shot At the end of September. Questions were immediately raised as to what this meant for the recipients of the Moderna and Johnson & Johnson vaccines.
- “The actual data we get in Moderna’s third shot and J & J’s second shot is literally weeks to weeks away,” he said. “We are currently working to provide data to the FDA, so the FDA can look it up and make decisions about boosters for those people.”
