"If we talk about effectiveness, we checked and conducted special experiments, we introduced both the covid vaccine and the influenza vaccine at the same time," Logunova quotes TASS.

According to him, "with such an application there are only two scenarios: either vaccines due to the fact that antigens compete, block each other, that is, reduce the effectiveness of one another, or ... there is a possibility of strengthening."

“We have shown that there is a significant increase in the effectiveness of the influenza vaccine when co-vaccinated with the COVID-19 Sputnik V vaccine,” he added.

According to data as of November 21, 36,970 cases of coronavirus infection were detected in Russia per day.

In total, 9 331 158 cases of COVID-19 have been confirmed in the country since the beginning of the epidemic.

Virologist Yevgeny Timakov, in an interview with FAN, gave a forecast regarding the situation with COVID-19 before the New Year holidays.
