Is it okay not to shoot the third time?

Generally, antibodies may not appear after the first injection, but only after the second injection. The third needle is to strengthen the antibody content. So it's usually three stitches. If the first shot appears, there is no need to shoot three times.

1 Some people will have immune delay after vaccination, that is, they may not produce antibodies immediately after three doses of vaccine.

There are also very few people who cannot produce antibodies due to genetic factors. These people are advised to avoid close contact with highly contagious people.

It is difficult to predict whether antibodies will be produced, but the probability of successful vaccination is still very high, generally above 95%

I suggest that you vaccinate according to the procedure first, and consider doing two and a half inspections about one month after the last injection to see if the vaccination is successful.

Generally, two pairs of semi-surface antibodies are positive, indicating that the inoculation is successful.
