For a single dose vaccine it's very effective and it's the only vaccine where we have concrete proof that it works against the South African Covid 19 variant, even in HIV/AIDS positive people (two factors very important in South Africa). But yeah Johnson and Johnson is a terrible company, even if they produced a good vaccine.
