Hepatitis B vaccine protects against hepatitis B. It is administered as intramuscular injection. A baby who is born to a chronically infected mother has a 70%–90% chance of being infected at birth. Many people who are chronically infected will suffer from serious problems such as cirrhosis (scarring of the liver) or liver cancer.
Genital human papillomavirus (HPV) is the most common sexually transmitted virus. Most HPV infections don’t cause any symptoms, and go away on their own. But HPV is important mainly because it can cause cervical cancer in women. More than 50% of sexually active men and women are infected with HPV at some time in their lives.
Rabies vaccines induce an active immune response that includes the production of neutralizing antibodies. This antibody response requires approximately 7–10 days to develop and usually persists for greater or equal to 2 years.
DPT vaccine protects against diphtheria, pertussis and tetanus. Diphtheria, tetanus, and pertussis are serious diseases caused by bacteria.
MMR vaccine is used to help prevent serious, sometimes fatal, infections caused by 3 viruses: measles (also known as rubeola), mumps, and rubella (also known as German measles).
