The Power of Boosters

David Leonhardt: “The CDC has begun to publish data on Covid outcomes among people who have received booster shots, and the numbers are striking… As you can see, vaccination without a booster provides a lot of protection. But a booster takes somebody to a different level.”

“This data underscores both the power of the Covid vaccines and their biggest weakness — namely, their gradual fading of effectiveness over time, as is also the case with many other vaccines.”

“Once you get a booster, your risk of getting severely ill from Covid is tiny. It is quite small even if you are older or have health problems.”
