The most effective way to reduce caseloads is to continue raising the country’s vaccination rate, through workplace mandates and other measures. Vaccinating children under 12 can also save the lives of older people.
Cases in the U.S. have already fallen 50 percent since Sept 1. If the declines continue — and can be maintained — the risks for older Americans will be much more manageable than they were in the late summer.
2. Give booster shots
Scientists are still trying to figure out how quickly vaccine immunity wanes. But the bulk of the evidence suggests that it does wane at least somewhat in the first year after vaccination, which creates additional risks for older people. Among that evidence: Covid case counts are higher in Britain, where vaccinations tended to happen earlier, than in other parts of Europe, as John Burn-Murdoch of The Financial Times has noted.
Waning immunity, in turn, suggests that booster shots can protect vulnerable people.
In the U.S., the federal government has not yet authorized booster shots for any recipients of the Moderna or Johnson & Johnson vaccines, although a scientific advisory panel has recommended them for people who are 65 and older, among others. Pfizer vaccine recipients 65 and older are already eligible for a booster once they are at least six months removed from their second shot.
Powell was set to receive a booster shot last week but had to postpone it when he became sick, a spokeswoman said.
3. Expand rapid testing
If rapid Covid tests were widely available, as they have been in much of Western Europe, they could help protect the elderly.
