Is the Hepatitis vaccine a must at 22? My concern is whether the vaccines are good here in Lebanon since apparently everything is contaminated. What other vaccines should be taken at this age?

Dr. Zakia Dimassi Pediatrics
At the age of 22 years, booster shots of Hepatitis A vaccine and TdaP (Tetanus, diphtheria, pertussis) are recommended because:
1- Our area is endemic for hepatitis A virus
2- Regarding TdaP, it was found that the doses given during childhood do not provide life long immunity. Moreover, there is the phenomenon of cocooning, whereby having all members of a household protected confers protection especially against pertussis in the vulnerable age groups (children younger than 2 years and elderly older than 65 years who are at a significantly higher risk of developing severe disease)
As for Hepatitis B vaccine, you need not re-administer a booster dose unless you will be working in the health care field or in close contact with sick people or inadequately vaccinated children (such as in refugees camps).
