Vaccines are one of the most important things in a dog's life. If you want to protect your dog's health, you must give your dog a vaccine.
How often is the interval between 2 shots of vaccine
There are different intervals between different vaccines. According to the information found, most vaccines are spaced within 2-4 weeks.
It is best to follow the official vaccine injection procedure. If you are not sure about the injection time, it is more appropriate to choose an injection interval of 21 days. Because if a few days earlier will not exceed the upper limit of 14 days, a few days later will not exceed the lower limit of 28 days.
The interval between 2 doses of vaccine can be delayed but not earlier.
The first dose of vaccine will produce high antibodies for a period of time, and then slowly decline. The time of injection of the second needle should not be too early, otherwise when the antibody is injected at a high concentration, these antibodies will neutralize the virus in the vaccine and make it ineffective. Generally speaking, the time between two shots of vaccine should not be less than 14 days.
If the injection of the vaccine is delayed, the concentration of antibodies produced by the previous vaccine will drop very low, which will have an impact on the latter vaccine, resulting in less antibodies, but will not cause the vaccine to fail. The longest interval should not exceed 28 days.
The enhanced vaccine is given once every few years.
Is it reasonable to say once every 2-3 years?
In recent years, foreign studies have shown that immunization has certain risks. Many dogs have loss of appetite, vomiting and diarrhea due to vaccination, whitening of the hair at the injection site, and suppuration of the skin. In addition, the protection of some vaccines (such as the INTWEI 4 vaccine) can reach 2-3 years after immunization, and reducing the frequency of immunization can reduce the incidence of non-reaction, so this statement is reasonable.
According to the national conditions, once a year is more reliable.
Vaccination in China is now very chaotic. Vaccines can be bought everywhere. Taobao, pet shops, private individuals and dog farms are all being vaccinated. In such a chaotic situation, no one can guarantee that the dog's vaccine will be reliable. The vaccine is very fragile. Improper transportation and injection, and dog's physical discomfort may cause immune failure. Therefore, it is more reliable in China once a year.
Old dogs that are immunized year after year can reduce the frequency of immunization.
If the dog has been insisting on immunization every year, the old dog can choose a long-term vaccine, 2-3 years to play once to reduce the risk of immune response.
