At the same time, the Yahoo News/YouGov survey of 1,610 U.S. adults — which was conducted from Sept. 14 to 16, immediately before the FDA advisory vote — also found Americans deeply conflicted over the possibility of getting a third shot before most of the rest of the world’s population has gotten their first, which could temper any disappointment.

Asked whether domestic booster shots or first shots for developing nations is “more important,” less than one-third of U.S. adults (32 percent) say “offering booster shots to as many Americans as possible.” A greater number (38 percent) say “offer first shots to as many unvaccinated people in other countries as possible,” and nearly as many (30 percent) say they’re not sure. Among fully vaccinated Americans, the share who want to prioritize boosters ticks up a bit (to 39 percent), but so does the share who think people abroad should get a shot first (45 percent).
