Vaccines against COVID-19, which are currently used, may be ineffective after a year due to the appearance of strains of the coronavirus that are not susceptible to these preparations, writes The Guardian newspaper, cited by BTA.
The publication cites the opinion of 77 experts: epidemiologists and virologists from 28 countries. The researchers participated in a survey organized by the Alliance for Vaccines for Humans.
Two-thirds of experts believe that the new strains, which will need to create a second generation of vaccines, could become widespread around the world in the next 12 months. According to a third of those surveyed, the new vaccines will be needed in the world only after 9 months. Respondents emphasized that in countries where vaccination rates remain low, new genetic variants of the coronavirus are more likely to develop resistance to first-generation drugs.
“New mutations occur every day and sometimes find a niche that gives them an advantage over their predecessors. These variants, which have the opportunity to detect them, will be able to spread more efficiently. Greg Gonsalves, associate professor of epidemiology at the Yale University said that by not vaccinating the world, we would open the door to more and more mutations, creating strains resistant to current vaccines. New immunizations will be necessary. “
