Unless Two-Thirds Of The World Is Vaccinated, Variants Of Covid-19 Will Get ‘Scarier And Scarier’: Scientist

A top scientist involved in research for vaccines for the novel Coronavirus has said that unless two-thirds of the world’s population is vaccinated, variants of the virus will keep “getting scarier and scarier”.

The comment has been made by Dr Drew Weiessman, professor of medicine at the University of Pennsylvania’s Perelman medical school and is jointly credited with the research behind mRNA vaccines by Pfizer-BioNTech and Moderna.

His comments have been carried by Hindustan Times.

“There are two things that have to happen for us to get the pandemic under control and stop the variants from appearing. We have to vaccinate the entire world and countries need to have a high enough percentage of people vaccinated — somewhere between 75-85 per cent in order to reach herd immunity. Until that happens, variants will keep appearing and they are going to keep getting scarier and scarier,” Weiessman has been quoted as saying.
