Fearless prediction. The FDA will approve a third shot very soon especially for immunocompromised people. Pfizer got ahead of the curve by going public with the booster announcement before the CDC and FDA were ready to go public. But every indication is that "a reasonable man or woman" would consider it prudent to administer a third shot to immunocompromised people The FDA is very likely to approve Pfizer and Moderna permanently and get over that business. Despite what I'm reading here and elsewhere, one years and the enormous number of people who have received the vaccinations make for a convincing result. The pressure must be enormous with Delta and autumn approaching particularly with schools, universities, stadia and offices/hospitals.
