How many times is the number of times a person needs to be vaccinated again after vaccination. Generally speaking, the vaccine needs two or three shots, which means that the vaccination time needs to be divided into two or three times. Different vaccines require different vaccination times.
Why should I be vaccinated several times? This is because the human immune system needs time to adapt to the stable immune effect. Repeated vaccination can stimulate the immune system to learn and remember how to identify and fight pathogens more thoroughly, thus maintaining a relatively long protective effect.
2, two vaccines and three vaccines
Common vaccine types include two vaccines and three vaccines. Double vaccine usually includes two pathogens, while triple vaccine includes three pathogens. Among them, the most common combined vaccines are measles vaccine and rubella vaccine, and the most common combined vaccines are pertussis, tetanus and diphtheria.
For these different kinds of vaccines, the suggestions of vaccination times are not the same. For example, measles vaccine and rubella vaccine are usually recommended in two ways, while pertussis, tetanus and diphtheria combined vaccine are recommended in three ways.
3. Period and time of vaccination
The period and time of vaccination also need attention. In the case of double vaccination, it is usually within 28 days after the first vaccination. The second and third vaccinations are generally carried out within 28 days and 6 months after the first vaccination.
It should be noted that the vaccination cycle of some vaccines may be different, and it is necessary to carefully understand the relevant vaccination cycle and time information before vaccination.
4. The importance of vaccination
Vaccination has become an important health problem in our life. Vaccination can protect people from various infectious diseases and reduce the possibility of sudden outbreak of diseases. In addition, vaccination can also reduce the risk and scope of disease transmission, thus improving the health level of the whole society.
Of course, vaccination is not completely without side effects. However, these side effects are usually mild and safe for most people. On the contrary, vaccination is very necessary in our life, which is also an important reason why we should actively participate in vaccination.
