Sputnik V and Moderna vaccine combination demonstrated the increased immune response

According to Buenos Aires' Deputy Health Minister Daniel Ferrante, when comparing vaccinations with the two components of Sputnik V and the AstraZeneca vaccine, "no significant changes were observed" in immunogenicity.

“But there was a greater impact for the combination of Sputnik V with Moderna, as there is a stronger immune response,” Ferrante said.

Also, the results of a study of combinations of Russian and Chinese vaccines are still being analyzed. There were no hospitalizations, the official said.

Earlier, Russian doctors proved that one dose of the Russian Sputnik V vaccine is enough to protect those who have had coronavirus.
