Which vaccine is the best one to receive? This is the most frequently asked question that people are considering.

Efficacy rates are often mentioned and have been reported as the following: Pfizer - 95%, Moderna - 94%, while Sinopharm is at 79.3% and Sinovac 78% and later 50.4%.

If you are only looking at these numbers, it's natural to say that China's vaccines aren't good as the others.

But this theory is misleading. First, you need to understand what these numbers mean.
