The growing consensus that at least some Americans will need a booster is partly tied to research suggesting that Pfizer’s vaccine is less effective after about six months.

The most recent figures from the Israeli Ministry of Health, released late this week, suggested that Pfizer’s vaccine was just 39 percent effective in preventing infection in that country in late June and early July, compared to 95 percent from January to April.

The vaccine remained more than 90 percent effective in preventing severe disease, and nearly as effective in preventing hospitalization. Israel began offering a third Pfizer dose to citizens with severely weakened immune systems on July 12.
