There is no definite time for the fourth shot of the new crown to be administered at this time.
The fourth dose of the New Crown vaccine is a booster shot that is administered on top of the third booster shot to achieve an increase in antibody levels. The fourth vaccination is currently practiced in Israel, and according to currently published vaccination data, after completion of the fourth New Crown vaccination, antibody levels can increase up to five times the pre-vaccination level, increasing resistance to the New Crown virus.
According to the Israeli vaccination data for Neocoronavirus vaccination, the fourth dose needs to be administered 4 months after the completion of the third dose. The vaccination of the fourth dose of the new crown vaccine is still in the mapping stage, and there is no vaccination requirement for the fourth dose of the new crown vaccine in China, nor is there a time for the fourth dose of the new crown vaccine to be administered.
