As covid-19 vaccines are being vaccinated in children, some parents are worried about whether their children's vaccinations should be used in half or at the discretion of adult doses.
Currently, the dose and composition of the COVID-19 vaccine is exactly the same for all ages, including children. The use of a uniform dose while ensuring safety is a global approach.
The dosage of therapeutic drugs is either considered by weight, and some also consider the surface area of the body, which is related to factors such as the metabolism of the drug in the body.
However, the mechanism of the vaccine is different from that of therapeutic drugs, and the antigens in the vaccine enter the body, not directly "exerting the effect", but through the immune system antigen presentation, immune cells recognize and produce antibodies, and the antibodies then play a role in blocking viral infection or preventing the onset of disease. The above process has no correlation with body surface area and weight.
In fact, the vast majority of vaccine doses do not distinguish between adults and children. For example, there is no dose difference between hepatitis B vaccine, cervical cancer vaccine, and pneumonia vaccine. In terms of mechanism, after the vaccine enters the body of a child, the mechanism of producing antibodies is exactly the same as that of adults, and there is no difference.
In addition, immunization program experts said that when vaccinating the new crown, they should pay attention to the health of their children. Because children over the age of 5 may have some psychogenic reactions, older children should avoid strenuous exercise and stay for 30 minutes. If a vaccinated child has a situation suspected of being related to an adverse reaction, report it promptly.
If you encounter overlaps with vaccinations from other immunization programmes or non-immunization programmes, it is important to ensure that covid-19 vaccines are more than 14 days apart from other vaccinations.
