Even Vaccinated, Why Cats Still Get Feline Distemper?

Section 1: Reasons for Feline Immunization Failure

1. Newborn kittens receive their initial immunity through their mother's milk, known as maternal antibodies. If a kitten still has high levels of these antibodies, vaccinating it can actually suppress the vaccine's protective effects.

2. Vaccines typically take around 10 days to reach their peak level of protection. If a kitten becomes infected with a virus before this time, it may lead to immunization failure.

3. Congenital immune deficiencies, immunosuppressive diseases, or internal parasites can also contribute to immunization failure in cats.

4. Stress during the period when the vaccine has not yet reached its full protective potential, failure to complete the full course of vaccinations on time, or improper storage of the vaccine can all result in immunization failure.

Section 2: Situations Where Cats Should Not Be Vaccinated

1. Kittens under six weeks of age should not be vaccinated due to the presence of maternal antibodies, which can interfere with the vaccine's effectiveness.

2. It's crucial to ensure that a cat is in good health before vaccination, as unwell cats may suffer worsened conditions following vaccination.

3. Cats should be dewormed before vaccination to ensure they are free from both external and internal parasites, as these can also hinder the immune response.

4. Cats in a constant state of stress may experience altered adrenal hormone secretion, which can affect their immunity. Therefore, it's advisable to avoid vaccinating cats with unstable emotional states or those recently adopted, and instead focus on calming them first.

It's important to administer vaccinations at a reputable veterinary clinic. Pet owners should refrain from purchasing vaccines and administering them themselves, as this can pose numerous safety risks. If you have any further questions or concerns, don't hesitate to consult with an online veterinary expert.
