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.
