A scientific analysis published by the UK Government’s official scientific advisory group says that a new Covid variant that will “lead to a vaccine failure” will almost certainly appear.
“These documents are released as pre-print publications that have provided the government with rapid evidence during an emergency”, the UK government’s publication website says.
The research says that it is “almost certain” that "a gradual or punctuated accumulation of antigenic variation that eventually leads to current vaccine failure."
According to the research, the only way of reducing the risk of an immune to vaccine strain emergence is "to reduce infection of and transmission from vaccinated individuals," and to "reduce the possibility of variant selection in vaccinated individuals."
Until now there is no known strain that is completely immune to the vaccine, however, newer variants tend to make vaccinations less effective.
"[New strains] show a reduced susceptibility to vaccine-acquired immunity, though none appears to escape entirely," the report says.
Previously similar information was published in the Sage Health Sciences journal, which only confirms the possibility of such a threat.
“The combination of high prevalence and high levels of vaccination creates the conditions in which an immune escape variant is most likely to emerge. The likelihood of this happening is unknown, but such a variant would present a significant risk both in the UK and internationally, ” the report published in Sage says.
