Why do dogs need to be vaccinated three times-

Miniature Pinscher (definite introduction)

Although vaccines cannot prevent 100% of infectious diseases, However, it can minimize the chance of getting sick, so most breeders will still choose to vaccinate their dogs. However, we will find that dogs need to be vaccinated three times in the first year, and then once a year. So why do dogs need to be vaccinated three times in the first year, and what are the methods and effects of doing so.

There is a general procedure after vaccination. The body secretes anti-substances and it takes a certain amount 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 the memory lymphocytes need to be stimulated repeatedly. The first immunization can only produce a small amount of antibodies, and the duration is short. It can only be stimulated multiple times at a reasonable distance. Produce more antibodies and longer-lasting protective effects. Therefore, when the second cross is carried out, the body can quickly produce a large amount of antibodies, which are 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 based on the conditions of the second time. 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.

From this point of view, the reason for three injections in the first year is to allow the dog’s body to produce a better amount of antibodies, so as to achieve the characteristics of long memory and protection time, and then throughout the year. Play a protective role.
