A certain decline in the level of antibodies 2-3 months after vaccination against the novel coronavirus is a normal phenomenon.

"Two months, sometimes three months after the vaccination the synthesis of antibodies is turned off and their level sometimes drops to zero.
"But that does not mean that the human body is no longer protected against this pathogen.
"The memory cells formed in the process whenever they encounter the same pathogen or the same antigen in the form of a vaccine begin to generate the required amount of antibodies not in two or three weeks' time, but literally within 3-4 days.
"For this reason a decline in the level of antibodies after vaccination is an absolutely normal development, so those who have been vaccinated should feel no worries," Gintsburg said. ■
