J&J said on Friday that in the US and seven other countries, the single-shot vaccine was 66 per cent per cent effective overall at preventing moderate to severe illness.
"Gambling on one dose was certainly worthwhile," Dr Mathai Mammen, global research chief for J&J's Janssen Pharmaceutical unit, told The Associated Press."The South Africa strain is still uncommon in the US and obviously we would want to see higher efficacy, but the key is not only overall efficacy but specifically efficacy against severe disease, hospitalisation, and death.
66% average efficacy, based on low numbers in South Africa, means a possible 85% in Australia in reality, depending virus variants in play. Single dose is the real bonus for J&J, plus enormous manufacturing capabilities means better coverage. Need to see ingredients.
judy_armes Tell me, if a vaccine even has 95 % efficacy is it stil less than getting the virus without a vaccine? I am confused by efficacy.
MarieAnneLeCler Only 66% effective is NOT good. I would never request this vaccine.
