Johnson & Johnson vaxers could be the tortoise that beats the Moderna hare. “A two-dose version of Johnson & Johnson’s coronavirus vaccine provides 94% protection against symptomatic infection, the company said Tuesday — making a two-dose regimen of J&J’s Janssen vaccine comparable to a two-dose regimen of Moderna’s or Pfizer’s. Plus, the company said, adding a booster dose to a single shot of the vaccine raised immunity even more, and should also protect people strongly against infection.” So J&J was pretty good. And J&J&J&J is really good. This isn’t the first time I’ve said this: We need more Js.
