Two dose version of Johnson & Johnson shot 94% effective against Covid-19, study finds
CNN
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.
The company released some details of three studies looking at various aspects of its Janssen vaccine, and said that, taken together, they showed the vaccine provided long-lasting protection that could be boosted with an extra shot.

The two men killed as they floated holding onto their capsized boat in a secondary strike against a suspected drug vessel in early September did not appear to have radio or other communications devices, the top military official overseeing the strike told lawmakers on Thursday, according to two sources with direct knowledge of his congressional briefings.
