What Twinrix Pediatric is and what it is used for
Twinrix Pediatric is a vaccine used in infants, children, and adolescents from 1 year up to and including 15 years of age and which protects against two different diseases: hepatitis A and hepatitis B. The vaccine works by causing the body to produce its protection ( antibody ar) against these diseases.
- Hepatitis A: Hepatitis A is an infectious disease that can affect the liver. The disease is caused by the hepatitis A virus. Hepatitis A virus can be transmitted from one person to another through food and drink, or when swimming in water contaminated with sewage. Symptoms of hepatitis A begin 3 to 6 weeks after coming into contact with the virus. Symptoms consist of nausea (general malaise), fever, and aches and pains. After a few days, the whites of the eyes and the skin may turn yellowish (jaundice). The severity and type of symptoms can vary. Young children do not always develop jaundice. Most recover completely, but the illness is often severe enough to require you to stay home from work for at least a month.
- Hepatitis B: Hepatitis B is caused by the hepatitis B virus. It causes swelling of the liver ( inflammation ). Virus et is found in body fluids such as blood, semen, vaginal secretions, or saliva (spit) from infected people.
Vaccination is the best way to protect yourself against these diseases. The vaccine does not contain any components that can cause infection.
