how long are kittens unwell after vaccinations?
<answer> 7-10 days <context> Kittens should be first vaccinated at 6 to 8 weeks and then every 4 weeks until they are 16 weeks or older. For most kittens this will mean 3 vaccinations. A kitten will not be fully protected until 7-10 days after the last vaccination.Under specific circumstances we may advise an alternative regime.. The cat was not healthy at the time of vaccination – ‘stress’ can prevent a good response to vaccination. For this reason your vet will give your cat a physical examination before a vaccination is given. 4. The cat may also be pre-infected with the ‘cat flu’ virus and incubating the disease.
