One thing I've found strange is the how Phase 3 trials are touted as the end of testing and ready to roll out to billions.
For example: Pfizer announcing 1.3 Billion does for 2021.
Phase 3 trials involve less than 50000 people and it's been less than 2 months since any vaccine has started their tests.
Yet we've seen previously that it can take a sample size of millions AND years for a side effect to show.
So jumping straight from a Phase 3 trial to mass vaccination of billions seems irresponsible.
In comparison, Sinopharm is also in the middle of conducting Phase 3 trials.
Plus it has concurrently been running what you could call Phase 4 testing, with 1 million vaccinations so far.
That increase the sample size substantially AND the overall timeline to detect any longer-term side effects.
That is important once you start talking about the risk of vaccinating billions.
So arguably the Sinopharm approach is better, if you have no choice but to start vaccinating billions immediately.
So despite criticism of the Sinopharm vaccine being given to 1 million people so far, it actually is a better and safer approach.
To be fair, if Pfizer and Moderna rollout their vaccines slowly, then it is still scientifically sound. However, it looks like the vaccinations would be rushed out to everyone as fast as possible.
