Immunity is the body's natural ability to resist diseases. The principle of vaccination is to give the body a small amount of completely harmless infection antigen, so that the body can gain immunity.
Second, the immunity of small pets.
1. Acquired immune protection of bitches: As long as bitches or cats are immune, puppies usually get immune protection in the first few weeks after breastfeeding. However, this acquired immune protection disappears very quickly, and after a few weeks, young pets will be at risk of contracting diseases. In this case, immunization is needed to replace maternal antibodies and provide protection for young pets.
2, the first immunization of young pets: the first immunization of young pets usually includes two needles, two to four weeks apart. This kind of immunization can start as early as 4-6 weeks old, but usually young pets are over this age when they are taken home, so they need to be vaccinated as soon as possible. Before vaccination, it is best to take your pet for a general examination to ensure that your pet is in a healthy state.
Three. Reinfection
The immunity of the disease will not be maintained permanently, but will gradually weaken. Once the pet's immunity begins to weaken, it will be in danger of being infected with the disease again. Therefore, for some diseases, it is necessary to strengthen immunization once every three years, while for others, it is necessary to strengthen immunization every year. It is suggested that the owner give his pet a health check-up once a year and inject the vaccine that needs to be strengthened.
4. What diseases can be prevented by immunization?
Immune prevention is one of the most effective ways to reduce pet infection. Pet diseases that can be prevented by vaccination mainly include canine parvovirus, canine distemper, infectious hepatitis, leptospirosis, cough and rabies. Among them, canine parvovirus and canine distemper are very easy to infect puppies, and the damage to puppies is also very fatal.
Owners should remember that nothing will happen after vaccinating their pets. Regular immunization is particularly important for maintaining protection, and immunization records are also very important and must be properly preserved. If your pet has any discomfort after vaccination, you must seek medical advice in time. If you have other related questions, you can also consult an online pet doctor.
