Pfizer, a major American pharmaceutical company, announced on the 8th the initial experimental results on the effect of its new coronavirus vaccine on the Omicron strain.
As a result, the effect of the neutralizing antibody that suppresses the action of the virus was significantly reduced by the two inoculations compared to the case of the conventional virus.
However, the effect of the third inoculation is 25 times that of the second inoculation, which is about the same as the effect on the conventional virus.
Pfizer says that it is important to proceed with the third inoculation, saying, "It seems that the second inoculation has the effect of preventing the aggravation, but it is clear that the third inoculation improves the protective effect."
