Upon taking your cat to a veterinarian with the complaint of an allergic reaction, he is initially likely to study your cat’s medical history. This may include cross-questioning such as, how many vaccinations were conducted previously? What environment does your cat live in? And further complete details of your cat’s characteristics. 

After a proper analysis, the veterinarian will conduct some tests based on the allergic reaction due to a particular vaccine injection. Conventionally, the allergic reactions are mild and are treated by using various anti-inflammatory drugs. One of the many examples of these drugs is ‘corticosteroids.’ Cats with mild or moderate allergic reactions are expected to go back to normal and be allergy-free in a week. However, if your feline friend is suffering from severe allergic reactions, you should immediately rush it to any nearby emergency clinic. Even if the allergic reactions are mild at the given moment, it is better to get your cat examined. Better safe than sorry!

If a cat survives this crucial phase, then it is likely to survive the disease. Furthermore, the study shows that it is rare for a cat to lose its life to a vaccine. To put this numerically, ten cats in every ten thousand that are vaccinated face serious allergic reactions.

Core and Non-Core Vaccines:


Vaccines are further categorized into two forms; core vaccines and non-core vaccines. For the reason of being free of doubt in every country, different vaccines are injected strictly on the grounds of the diseases’ presence. This is because a concerned condition might not even be present in a particular country. 

Core vaccines are the ones that are necessary and crucial for all the cats due to the reason of widespread bacterial infections. Non-Core vaccines, on the other hand, are only given to cats in case there of an urgent requirement. They are injected into a cat based on his/her age, contact with other cats, and their lifestyle. A few examples of core vaccinations are as follows; 

  • Rabies
  • Feline calicivirus
  • Feline herpes virus 
  • Feline panleukopenia.

Whereas the non-core vaccines are; 

  • Chlamydophila Felis 
  • Feline immunodeficiency virus
