What should I pay attention to when receiving the hepatitis B vaccine?

Generally speaking, when receiving the hepatitis B vaccine, it is important to confirm your health status, check for allergies, follow the vaccination schedule, monitor post-vaccination reactions, and understand contraindications for special populations. The details are as follows:

1. Confirm your health status: Before vaccination, ensure you are not suffering from any acute illness, such as a cold, fever, or diarrhea. If you are experiencing an acute episode of illness, vaccination should be postponed until you have fully recovered, to avoid worsening the condition or affecting the vaccine's effectiveness.

2. Check for allergies: You should inform your doctor in advance about any history of allergies, especially if you are allergic to yeast or any components of the hepatitis B vaccine. Those who have experienced severe allergic reactions after receiving other vaccines should also provide accurate information so that the doctor can determine whether vaccination is suitable.

3. Follow the vaccination schedule: The hepatitis B vaccine usually follows a specific schedule. The common regimen involves receiving the first dose, followed by the second and third doses one month and six months later, respectively. It is important to strictly adhere to the recommended vaccination times without advancing or delaying them arbitrarily, to ensure sufficient antibody production in the body.

4. Monitor post-vaccination reactions: After vaccination, you should remain at the vaccination site for 30 minutes for observation and leave only if there is no adverse reaction. After returning home, if the injection site shows mild redness, swelling, or pain, this is usually a normal reaction and will resolve on its own. However, if severe swelling, fever, or other unusual symptoms occur, prompt medical attention is required.

5. Understand contraindications for special populations: Special groups such as pregnant women, breastfeeding women, and individuals with severe chronic diseases should consult a doctor before vaccination. The doctor will evaluate whether vaccination is appropriate based on individual circumstances; self-decision should not be made.

After vaccination, keep the injection site clean and dry, and avoid scratching. In daily life, maintaining regular作息 (作息 should be translated as "routine"), balanced nutrition, and moderate exercise can help enhance immune function and maximize the protective effects of the vaccine.
