In kittens two injections of cat vaccine are given at 9 and 12 weeks against CAT FLU (2 types of respiratory infection), ENTERITIS ( a nasty killer viral diahorrea) and LEUKAEMIA ( a viral blood cancer).
In older cats the 2 vaccinations are given 3 weeks apart.
Immunity after the second vaccination takes up to 4 weeks to develop.
(The interval between the 2 injections of a primary course can be 4 weeks.)
An ANNUAL BOOSTER is given each year to maintain the protection
