Vaccine effectiveness compared

by Gentia | 16 November 2020

With many governments around the world proposing to make vaccine against SARS-CoV-2 mandatory for all their citizens, big pharmas have gone into overdrive in a race to bring their product to market which could potentially be worth billions of dollars.

Recently, the front runners have announced their COVID vaccine effectiveness to be over 90%.

Pfizer: 90%

Moderna: 94.5%

AstraZeneca (to be announced)


These claims are quite astonishing, especially when compared to the effectiveness of normal flu vaccines which usually take much longer to develop.
