Democrats and the public-health clerisy denounced President Trump for rushing Covid vaccines. They’ve been curiously quiet about the Food and Drug Administration’s gunshot approval last week of revamped booster shots with no trials showing they are safe or effective.
The FDA granted emergency-use authorization to mRNA shots by Pfizer and Moderna that are bivalent, targeting the initial Wuhan variant as well as the currently predominant BA.4 and BA.5 strains. The Biden administration ordered 171 million doses earlier this summer, so FDA authorization seems to have been a fait accompli. The FDA probably should have made the reconfigured vaccines available to high-risk and elderly patients. But the case is weak for young people, given the limited benefit and uncertain risks.
