If vaccinated, some will have local redness, swelling, pain and other reactions, varying in severity, and some may also have systemic reactions such as mild fever.
Some vaccines are inactivated. If you are allergic or have a cold, fever and other diseases, injection is not recommended, and the impact on other parts of the body is generally not great, depending on the nature and composition of the vaccine.
a
Vaccination is harmless to the body. Vaccine is an attenuated live vaccine extracted from virus, which can stimulate the body to produce antibodies and protect the body. But the vaccine is a foreign body in the body after all, which will cause a certain pyrogen reaction. It is normal for some babies to have a low fever after vaccination and return to normal after 2-3 days. Because of this, premature babies, malnourished children or infected children are not allowed to be vaccinated, and only healthy babies can be vaccinated.
Most of the functions of vaccines are to produce corresponding antibodies in the human body, which can cope with the invasion of disease bacteria or viruses. For example, rabies vaccine is aimed at rabies virus, and tetanus vaccine is aimed at Clostridium tetanus. These two prevention methods are not in conflict and do no harm.

Improper vaccination is easy to be allergic. Before vaccination, people should first know whether they are allergic to certain drugs. If there is allergic phenomenon, you should consult a doctor in time and choose the corresponding vaccine type according to your own physique under the guidance of a doctor.
For children, their immune system and function have not been fully formed. Compared with other healthy people with immune formation, the effect of vaccination is biased, and some of them are prone to adverse reactions, such as live attenuated vaccines. For some children who are prone to bacterial infection or virus infection, explain the situation to the doctor before vaccination, confirm whether they can be vaccinated and the precautions after vaccination.
Before vaccination, if you find yourself with acute symptoms such as cold and fever, especially patients with severe fever, you should temporarily postpone vaccination during treatment. If you have recovered, you should also postpone vaccination until your body is fully recovered.
People with special diseases (such as nervous system diseases, epilepsy, convulsions and encephalopathy) need to explain their illness to doctors in advance before vaccination, and carry out vaccination under the guidance of doctors.
c
In order to reduce the infection and adverse reactions after vaccination, shower before vaccination to wash off bacteria and residual substances on the body, so as to reduce the risk of infection after vaccination. Do not leave in time after vaccination. It is best to wait in the same place for half an hour and leave after the body has no adverse reactions. You should avoid strenuous exercise and spicy food after returning home. 1-2 days later, you can resume your daily exercise and diet.
