Two-Dose Version Of Johnson & Johnson's COVID 19-Vaccine Is 94% Effective
By: KDKA-TV News Staff
PITTSBURGH (KDKA) -- Johnson & Johnson is reporting that a two-dose version of its COVID-19 vaccine provides 94% protection against symptomatic infection.
That makes the two-dose regimen of Johnson & Johnson's vaccine comparable to a two-dose regimen of Moderna or Pfizer's vaccine.
The company is now saying that adding a booster dose to a single shot of the vaccine raised immunity even more -- and should also protect people strongly against infection.
