People who have been vaccinated against coronavirus with a BioNTech vaccine produce 10 times more antibodies than those who preferred the Chinese drug Sinovac, the South China Morning Post writes, citing a corresponding study.

According to the study, the level of antibodies produced during Sinovac vaccination is “the same or lower” than that recorded in people who have naturally had COVD-19. This suggests an “alternative strategy” – the use of a booster dose of the vaccine for the most vulnerable groups of the population, including the elderly and people with weak immunity.

“The difference in the concentration of neutralizing (virus) antibodies indicated in our study may mean significant differences in the effectiveness of vaccines,” the newspaper quotes the study.
