Soumya Swaminathan, a senior researcher at the World Health Organization (WHO), says that herd immunity to coronavirus infection will not be achieved in 2021 despite the growing level of vaccines’ availability. The WHO expert stated this at a briefing on Monday, Deutsche Welle reports.
"We will not have time to reach any levels of population or herd immunity in 2021," Swaminathan said.
According to health experts, limited access to vaccines in developing countries, skepticism about vaccination, and the potential for virus mutations are the main mitigating factors for it.
As we reported earlier, Scientists at the Italian National Institute of Nuclear Physics have launched a website that provides all the information about coronavirus vaccination in countries around the world.
In particular, the site contains a map showing which drugs were used by a particular country and how the vaccination campaign is progressing.
At present, 42 countries are rolling out safe and effective Covid-19 vaccines. 36 of these are high-income countries and six are middle-income.
