I don’t entirely understand the arguments myself, but it goes something like what MarketWatch said here:
“Experts are quick to point out that the clinical trials were conducted at different times — Pfizer and Moderna conducted their trials before several mutated variants had been reported, whereas Johnson & Johnson’s trials were conducted after that. Consequently, Johnson & Johnson has clinical-trial data to show its vaccine can work effectively against variants first reported in the U.K., South Africa and Brazil.”
That actually says it’s least effective against the South African variant.… so… there’s that.
I originally heard about it from my wife who heard about it from Sanjay Gupta’s podcast who said there was a study showing this, but I couldn’t find whatever Sanjay was talking about.
