Despite the deployment of Covid-19 vaccines in a number of countries, the World Health Organization warned on Monday that herd immunity would not be achieved this year.
AFP: Countries around the world are impatiently awaiting vaccines that will finally allow a return to normal in the months to come.
But WHO chief scientist Soumya Swaminathan has warned that it will take time to produce and administer enough doses to stop the spread of the virus.
“We will not achieve any level of population immunity or herd immunity in 2021,” she said during a virtual press briefing from WHO headquarters in Geneva, stressing the need to continue measures such as physical distancing, hand washing and wearing a mask to curb the situation. pandemic.
She praised the “incredible progress” made by scientists who have achieved the unthinkable of developing not one but several safe and effective vaccines against a brand new virus in less than a year.
But, she said, deployment “takes time.”
“It takes time to increase the production of doses, not just millions, but here we are talking about billions,” she stressed, calling on people to “be a little patient”.
Swaminathan pointed out that eventually, “the vaccines are going to come. They will go to all countries. ”
“But in the meantime, we must not forget that there are measures that work,” she said.
It would be necessary to continue to take public health and social measures aimed at curbing transmission “for the rest of the year at least”.
