Covid-19 Vaccines May Have Saved 31 Million Lives (so far)
A new study estimates the efficacy of Covid-19 vaccines
In the never-ending saga that is the Covid-19 pandemic, no subject is more contentious than vaccines.

The researchers estimate that the jabs have prevented somewhere between 18 and 31 million deaths between the 8th of December 2020 and the 8th of December 2021, worldwide.
