Samoyed( (Definite introduction)
Generally, the first dose of vaccine can be given about 45 days after a dog is born, the second dose of vaccine should be given every three weeks, and the final shot of rabies vaccine should be given every three weeks. All vaccines. Do you know why dogs need three shots of vaccine? Is there any reason for this?
There are general procedures after vaccination. It takes a certain amount of time for the body to produce antibodies through the stimulation of the vaccine, which may take 2-3 weeks. However, the number of antibodies produced this time is very small, and the protection period is also short. These antibodies are ineffective against infectious diseases and cannot prevent epidemics, so it is not feasible to vaccinate only once. There are general procedures after vaccination. The body receives anti-substances - the stimulation of the vaccine, and it takes a certain period of time to produce antibodies, which may take 2-3 weeks. However, the number of antibodies produced this time is very small, and the protection period is also short. These antibodies are ineffective against infectious diseases and cannot prevent epidemics, so it is not feasible to vaccinate only once.
Moreover, the reason why three injections of the vaccine are needed is that memory lymphocytes need to be repeatedly stimulated. This is determined by biological immunology. The first immunization can only produce a small amount of antibodies, and the duration is short. At a reasonable distance, Only with repeated stimulation can more antibodies and long-term protective effects be produced.
Therefore, if the second cross is carried out, the body can quickly produce a large amount of antibodies, dozens of times more than the first response, and they will remain in the body for a longer time. If the third cross is performed 3-4 weeks after the second cross, the number of antibodies produced by the body will increase dozens of times on the basis of the second cross. This gives the dog the ability to resist infectious diseases in the body, and it can last up to a year in the body. Furthermore, it is enough to vaccinate your dog once a year.
Reminder: If you take your pet for vaccination, it is best to choose a guaranteed pet hospital, because only some hospitals receive vaccines through formal channels.
