What about boosters? What is the status of boosters?
- Moderna started a trial of a B.1.351 booster
on 24 Feb 2021on 10 March 2021 with 60 people and somehow started again on 31 March 2021 with 210 people.
- Pfizer said they would do a trial also, but did not give a date.
- Novavax expects to start trials of a B.1.351 booster in 2021Q2.
I estimate that it will take as little as 4-7 weeks after the start of a trial to get a booster approved. Pfizer has said their manufacturing takes 60 days, so presumably it would take slightly longer to switch the line over, so say 9 weeks. Assume that Moderna’s line is similar to Pfizers. That means we should see B.1.351 boosters between May 26th and June 16th.
This site thinks it will be 5 months for the Moderna booster to get results, which was about as long as it took Moderna to do its full Phase 3 trials.
