Other vaccines that are recommended but have to be purchased, i.e. they are not supplied free of cost, are described below.
1. Hepatitis-B vaccine: It is a killed viral vaccine having excellent protection against Hepatitis-B virus. There are 5 common hepatitis viruses; A to E. Out of these, at present, vaccines are only available against Hepatitis A & B. Hepatitis-A causes only acute (lasting for a brief time say 1-2 weeks) liver disease while Hepatitis-B may cause a chronic liver disease which may ultimately lead to liver failure. It has also been known to cause liver cancer. That’s why one should get oneself immunised against it.
