The BA.5 Omicron subvariant, now the dominant coronavirus strain in the United States, is four times more resistant to Covid-19 vaccines, according to a new study published in Nature.

The study found that the variant is four times more resistant to messenger RNA vaccines than previous Omicron strains, which include the Pfizer and Moderna Covid-19 vaccines, Xinhua News Agency reported.

The strain is “hypercontagious” and is contributing to increased hospitalizations and intensive care unit admissions, the Mayo Clinic said in a report Thursday.

The BA.5 strain accounted for 65% of the country’s Covid-19 cases in the week ending July 9, according to the latest data from the US Centers of Disease Control and Prevention.

Unvaccinated people are about five times more likely to contract the virus than those who are vaccinated and boosted, while the risk of hospitalization is 7.5 times higher and the risk of death is 14 to 15 times higher, said Gregory Poland, head of the Mayo Clinic. Vaccine Research Group.
