Covid-19: Moderna has developed a vaccine against Pirola, the new variant

The American laboratory Moderna announced that its updated vaccine against the new variant of Covid-19, called "Pirola" or BA.2.86, showed an 8.7-fold increase in neutralizing antibodies during clinical trials. These data have been submitted to the US FDA for approval.



Moderna President Stephen Hoge emphasized that this vaccine update would be a crucial tool for the upcoming vaccination season. The Omicron BA.2.86 variant, with more than 30 mutations in the Spike gene, is under global surveillance due to its ability to evolve rapidly.



Although existing vaccines and immunity acquired from previous infection provide some protection against this variant, Moderna is seeking to strengthen the effectiveness of its vaccine.
