It is important to booster vaccines in kittens every 3-4 weeks until they reach 16 weeks of age. The reason for this is because they are slowly losing protection from the antibodies from their mother, and they will not have a full response to the vaccines until those are completely lost. Giving a kitten vaccines every 3-4 weeks keeps them protected during their kittenhood. I have attached a link to the vaccine recommendations from the American Association of Feline Practitioners for you to review if you would like additional infomation. https://www.catvets.com/guidelines/practice-guidelines/feline-vaccination Please let me know if that was helpful. Thanks for using PetCoach.
