One day is enough to update EpiVacCorona vaccine against new COVID-19 mutations

Just one day will be enough to update Russia's EpiVacCorona vaccine to ensure protection against new mutations of the coronavirus, the Russian State Research Center of Virology and Biotechnology Vector's General Director Rinat Maksyutov said.

"If the virus suddenly mutates, and a mutation occurs in the areas where we selected peptides, if we need to update the vaccine, then it will take no more than one day to upgrade vaccine composition," Maksyutov said.

Vector's director clarified that developing peptides and releasing a vaccine takes time, apart from that, research must be conducted for the updated vaccine.

"I hope that it will be possible to conduct just an abbreviated study, like we do with seasonal influenza vaccines when new strains appear, but, since there have been no precedents with a coronavirus vaccine so far, it is difficult to say anything for sure, everything will depend on the regulator," Sputnik cited Maksyutov as saying.

EpiVacCorona vaccine was authorised for seniors aged 60 and over in March.

The vaccine is a peptide-based drug that relies on a synthetic platform. Artificially-synthesised short fragments of viral proteins - peptides, which are contained in the vaccine, help the immune system learn how to recognise and then neutralise the virus.
