Dissemination of new strains of Coronavirus COVID-19 dictates the need to create modified vaccine types over the next year or even earlier, reports The Guardian with reference to a survey of 77 specialists from 28 countries, conducted by NPO People’s Vaccine Alliance.
Two-third of respondents spoke for such a schedule of development of new vaccines, about one third believes that it is about nine months or less.
At the same time, 88% of experts believe that the small scale of Vaccination from COVID-19 in a number of countries increases the likelihood of new varieties of vaccine-resistant viruses.
“New mutations arise every day. Sometimes they find a niche that suits them more than their predecessors. These luck options can be transmitted to more efficiently and potentially avoid an immune response against previous strains,” said the Associate Professor of Epidemiology Yale University Gregg Gonzalez .
In the meantime, The Guardian notes, until such states as the US and the United Kingdom attracted at least one dose of vaccine more than a quarter of the population and provided themselves with the supply of hundreds of millions of doses of the drug, other countries like South Africa and Thailand vaccinated less than 1% of the inhabitants. In some countries, vaccination has not yet started.
