The vaccines are miraculously effective

The evidence just keeps piling up:
Three scientific studies released on Monday offered fresh evidence that widely used vaccines will continue to protect people against the coronavirus for long periods, possibly for years, and can be adapted to fortify the immune system still further if needed.
Most people immunized with the mRNA vaccines may not need boosters, one study found, so long as the virus and its variants do not evolve much beyond their current forms — which is not guaranteed. Mix-and-match vaccination shows promise, a second study found, and booster shots of one widely used vaccine, if they are required, greatly enhance immunity, according to a third report.
Scientists had worried that the immunity conferred by vaccines might quickly wane or that they might somehow be outrun by a rapidly evolving virus. Together, the findings renew optimism that the tools needed to end the pandemic are already at hand, despite the rise of contagious new variants now setting off surges around the globe.
“It’s nice to see that the vaccines are recapitulating what we’ve also seen with natural infection,” said Marion Pepper, an immunologist at the University of Washington in Seattle.
It seems bad that many Republican elites (and their fellow travelers) are successfully discouraging their followers from taking them, but once you take enough anti-empirical positions to favor one special interest or the other eventually your commitment to anti-empiricism becomes so strong it will extend to areas in which it primarily hurts your own team.
