For first-time vaccinations, 2-month-old kittens need three doses of the triple vaccine, costing between 80-120 yuan per dose, with each dose spaced 3-4 weeks apart. Adult cats only need one dose of the triple vaccine annually as a booster, and immune protection is generally established within 7-10 days after vaccination. 
Feline triple vaccine is a vaccine that can prevent infection by three viruses. Common feline triple vaccines in China include Felix Feliss, Intervet (Netherlands), and PHC (Korea). Felix Feliss is the most commonly used triple vaccine in China because of its high safety profile. It is the only officially approved imported vaccine in my country, ensuring proper refrigeration during transportation and preventing vaccine inactivation. Generally, pink indicates the vaccine is within its expiration date; a discoloration may indicate it has expired.
