The third dose of cat vaccine is usually delayed by no more than 1 week. Normally, each shot of the vaccine is administered 21 days apart. If delayed, the immune effect of the vaccine may be affected, resulting in insufficient antibody levels in the cat's body. The owner may consider taking the cat for an antibody test. If the antibody is high, it means that the antibody has been successfully generated, and then there is no need to take a shot. ​​​​​​

If the data shows that the antibody level is insufficient, it is recommended to take one or two additional doses of infectious disease vaccines based on the antibody level. Cat vaccines are best carried out in conjunction with deworming, 5-7 days before epidemic prevention.
