Kittens can usually start getting vaccinated around two months old. Of course, the reason for choosing this time period is mainly based on the development of the kitten's immune system and the point at which the protective power of maternal antibodies declines.
In fact, we generally recommend that cats be at least two months old, and preferably no later than four months, before their first vaccination. Furthermore, before vaccinating a cat, it's essential to complete a series of internal and external deworming treatments to ensure the cat's health. For example, the feline triple vaccine specifically targets these infectious diseases; cats need to receive three doses of the feline triple vaccine in their first year, followed by annual doses thereafter.
