關於B型肝炎
乙型肝炎可以通过已经使用了 30 多年的疫苗进行预防。该疫苗为预防乙型肝炎病毒 (HBV) 感染及其致命性提供了一种简单有效的方法。包括儿童、青少年和成人在内的所有人都应该在还没有感染慢性乙肝前，接种完整的疫苗。
Who Should Get Vaccinated?
Hepatitis B vaccine is available for all age groups. The hepatitis B vaccine is recommended by the CDC for all infants, all children or adolescents younger than 19 years of age who have not been vaccinated, all adults age 19 through 59 years, and adults age 60 years or older with risk factors for hepatitis B infection.
Negative Test Result? Consider Vaccination.
If both your blood tests (HBsAg and anti-HBs) are negative, you have not been infected with hepatitis B nor are you protected. Get vaccinated to protect yourself.
Screening before vaccination is vital, as vaccination cannot cure hepatitis B if you are already infected.
Where to Get the Hepatitis B Vaccine
Getting vaccinated for hepatitis B is now more convenient than ever.
