Can my pet be vaccinated if it isn’t feeling well?

October 23, 2025

It is important that your pet is in good health at the time of vaccination. If your pet is not feeling well—due to illness, fever, or reduced appetite—the veterinarian will usually postpone the vaccination.

A weakened immune system can make the vaccine less effective or cause a stronger reaction. During the consultation, the veterinarian will always assess your pet’s health and discuss with you the best time to vaccinate.
