It is noted that in 79% of volunteers on the 42nd day after vaccination with EpiVacCorona, IgG antibodies to coronavirus were detected.
Vektor emphasized that this result is immunological and not epidemiological efficacy.
“It should not be confused with epidemiological efficacy, which comes from other data and is calculated using a special formula.
When they talk about the effectiveness of a vaccine, they mean precisely its epidemiological effectiveness, "said Tatyana Nepomnyashchikh, deputy head of the Vector Center.
Earlier, Rospotrebnadzor said that the proportion of patients with coronavirus among those who completed the full course of vaccination is less than 1%.
