What are the side effects of hepatitis B vaccine

First, the vaccination of hepatitis B vaccine should be carried out according to the specific situation and the doctor's advice. After vaccination, the general reaction is mild. A small number of people may have symptoms such as low fever, redness and swelling of the vaccination site, tenderness, etc., which generally disappear within 1 to 2 days. The safety of the use of hepatitis B vaccine has reliable guarantee. From the perspective of immune effect, a large number of studies have shown that the antibody positive conversion rate of recipients is more than 90%, and the protection rate is more than 80% three years after vaccination.

Second: before the injection of hepatitis B vaccine, we need to check the two pairs and half of hepatitis B and liver function, which can be inoculated only when they are normal. The injection of hepatitis B vaccine needs to be inoculated according to the 016 plan. The first injection should be given on the same day, the second injection should be given after one month, and the third injection should be given after six months. In the process of re inoculation, the injection time should not be delayed for no reason, so as not to affect the production of hepatitis B surface antibody.

Third: hepatitis B vaccine injection, mostly safe, no adverse effects on the human body. If before the injection did not check hepatitis B two and a half, is not suitable for injection, most of the body does not check after the hepatitis B antibody injection. It is suggested that hepatitis B two and a half check, antibody production, can not be injected vaccine. If there is no antibody, it is better to switch to other brands of vaccine.
