Approximately 70% of the world’s population should be immunized to ensure the end of the pandemic, the chief scientist of the World Organization of the Health (WHO), Soumya Swaminathan stated, Explica reports.
Although it remains to be seen how effective future vaccines will be, Swaminathan and the director of the WHO Immunization Department, Kate O’Brien, estimate that this would be the ideal percentage, although the goal by 2021 is to reach 20%.
"No company that is investigating will be able to immediately have doses for everyone," O’Brien warned. She also indicated that it is therefore important that all laboratories continue their investigations even if one of them is ahead of the others.
The total number of infections reached 51,251,715 on Wednesday while the death toll reached 1,270,930, according to the WHO.
As we reported earlier, Ukrainian Health Minister Maksym Stepanov expects that the coronavirus vaccine will arrive in Ukraine at the end of the first quarter of 2021.
"In my opinion, registration should take place before the new year. Then the process of production and supply of vaccines begins. I think that we will actually get the vaccine at the end of the first quarter at best," the official said.
According to him, none of the vaccines that the world's pharmaceutical companies are working on has yet passed the third stage of clinical trials.
