Inject hepatitis B vaccine?

No matter what the physical condition, hepatitis B vaccine is the best safe way, and healthy people are also best to be vaccinated with hepatitis B vaccine. If you are infected with hepatitis B or have been found abnormal, then you don't need to get hepatitis B vaccine. At this time, even if hepatitis B vaccine is injected, it has no effect. A large number of field observations in various places have proved that hepatitis B vaccine is safe and reliable. Only a few people who have been injected with the vaccine have slight redness and induration (diameter less than 1.5cm) at the injection site, but they usually disappear naturally within 2 ~ 3 days without serious adverse reactions.
