The probability of side effects is different.
In the same sample group, the number of samples produced by domestic vaccines is more than that of imported vaccines. Although this is only a difference in probability, the probability of side effects of imported vaccines is really small. However, no matter which vaccine, there is no guarantee that there will be no side effects at all.
There are significant differences in protection period.
There is a significant difference in the immune protection period between domestic vaccines and imported vaccines. Domestic vaccines, whether attenuated or inactivated, have a significantly shorter protection period than imported vaccines. Take hepatitis B and DTP vaccines as examples. The protection period of domestic vaccines is 2 years and 1.5 years respectively, while the protection period of imported vaccines is as long as 5 years and 6 years!
Imported vaccines are more worthy of choice.
For the baby's health, if conditions permit, it is recommended to choose imported vaccines. They have less probability of side effects and longer protection period, which can better protect the baby's health.
Precautions for vaccination
The same vaccine needs to complete a course of treatment to produce antibodies. This means that continuous inoculation must be carried out according to the regulations, and mixing and matching are not allowed, otherwise the inoculation may fail or the effect may be discounted. The statement that "domestic vaccines are more suitable for China people's physique" is inaccurate. The principle of vaccine stimulating immune system is the same, so there is no regional difference.
