haha Cheens wouldn't have guessed a vaccine development is not like making fake Armani. Also, it doesn't matter when you start Phase 3 trials, you can start in February and still continue into December, effective immune response is checked for more than a year until a vaccine is certified safe and effective.
No vaccine so far is 100% effective, the ones with cutting edge research have only produced vaccines that are at least 90-95% effective, Under normal circumstances, such vaccines are straight out rejected.
Brazilian president may be wrong about Trump's character because he doesn't need to rely on experts to figure that out, unlike something like a vaccine. India already has two vaccine candidates, and a drug candidate going through phase 2 trials. You can moan even more, I enjoy it.
