Hepatitis A and B vaccine can cause pain, redness, fever, headache, fatigue, nausea, vomiting, rash and other adverse reactions at the vaccination site, which are usually mild and do not require special treatment. However, special groups such as pregnant women, people with low immune function and people with chronic diseases need to be vaccinated under the guidance of a doctor. Hepatitis A and B vaccine is used to prevent hepatitis A and hepatitis B. After vaccination, the body produces antibodies to prevent the virus infection. However, some adverse reactions may occur after vaccination. The following are some common adverse reactions of hepatitis A and B vaccine: 1. Pain and redness at the vaccination site: This is the most common adverse reaction, usually within a few hours to days after vaccination. These symptoms usually disappear within a few days. 2. Fever: After vaccination, fever symptoms may appear. These symptoms usually appear within hours to days after vaccination, and the temperature generally does not exceed 38.5 ° C. If the temperature exceeds 38.5 ° C, or the fever lasts for a long time, seek medical attention promptly. 3. Headache, fatigue: These symptoms usually appear within hours to days after vaccination and usually disappear on their own within days. 4. Nausea, vomiting: These symptoms usually appear within hours to days after vaccination and usually disappear on their own within days. 5.

It should be noted that the above adverse reactions do not necessarily occur, and are usually mild and do not require special treatment. If serious adverse reactions occur, such as allergic reactions, breathing difficulties, etc., seek medical attention immediately. For special groups, such as pregnant women, immunocompromised people, people with chronic diseases, etc., special attention should be paid when vaccinating hepatitis A and B vaccine. These groups may be at higher risk of adverse reactions after vaccination and therefore need to be vaccinated under the guidance of a doctor.
