Andy Slavet, a former adviser to the White House Pandemic Task Force, considered that vaccines against the new strain of the Corona virus will not be available until the summer of 2022.
“Both Pfizer and Moderna believe that it will take 100 days to design vaccines against the new version. Production, approval and distribution take time, but we are becoming more effective,” Slavet said, in a tweet via “Twitter” posted on Friday evening.
“If we start in early December, the new vaccines will be available to the whole world by summer,” the health expert added
Slavett also predicted that it would take two weeks to assess the effectiveness of mRNA-based vaccines.
This comes against the background of monitoring the rapid spread of the new “B.1.1.529” strain, which has raised widespread fears in the world and resulted in a number of countries taking the decision to stop flights with South Africa and its neighboring countries.
And the first infection with this strain was recorded in Botswana, in a citizen of South Africa, where the largest number of patients was monitored, amounting to about 80 injured.
This copy carries twice the number of mutations in the “delta” strain, among which are associated with avoiding the immune response resulting from both previous infection and vaccination, as well as mutations associated with increased infection.
On Friday, the World Health Organization classified the new strain as “alarming”, the fifth version to be placed in this classification.
