If you want to know whether the vaccine is successful, the best way is to conduct an antibody test at a pet hospital to see if the vaccine has formed antibodies in the cat’s body. If antibodies are formed, it means the vaccine is working. ​​​​​​

Cat antibodies mainly detect antibodies against three infectious diseases: feline distemper virus, calicivirus, and herpes virus. If the antibody concentrations of the three infectious diseases are relatively high, it proves that the vaccine has been vaccinated and the vaccination was successful. If the antibody concentration is insufficient, it means that the vaccine has not been vaccinated or that the vaccine has not produced antibodies.
