It is usually possible to get the first two inactivated vaccines and the third recombinant vaccine. There are inactivated and recombinant vaccines for many diseases, and it is usually possible to receive two inactivated vaccines followed by a third recombinant vaccine. However, it is recommended that all inactivated vaccines be given, as this helps the body to produce effective antibodies and reduces the chance of adverse reactions. Vaccination plays an important role in the prevention of diseases as it can produce antibodies to prevent further aggravation of the disease when the disease-causing agent invades the body. Proper care should be taken after vaccination. For example, avoid bathing for one day after vaccination and eat less spicy and stimulating food to prevent allergic reactions. In summary, after inactivated vaccination, you can also receive recombinant vaccine, if the adverse reaction occurs and persists for a long time, it is recommended to seek medical examination and treatment as soon as possible.
