Do you just make things up as you go along?NO test result are available to confirm that the Sputnik and J&J is effective against the SA variant.
So, this is just abunch of idiots clinging to the only straw in the pond.
In the US, the J&J vaccine offers 72% efficacy, but this dropped to 57% in South Africa, where it was tested on the variant (501Y.V2), which is so highly contagious that it has caused a second wave much higher than the first wave of Covid-19 in the country.
The vaccine's efficacy against moderate and severe disease ranged from one country to another: 72% in the US, 66% in Latin America and 57% in South Africa. This was measured starting one month after the shot. In South Africa, 95% of cases in the trial were due to a variant known as B.1.351, which is known to be more contagious and carries mutations that may make the virus less susceptible to the antibody immune response -- including antibodies prompted by vaccination.
