Hepatitis A is a vaccine-preventable infection caused by the hepatitis A virus (HAV). Over 150 million new infections of hepatitis A occur annually. HAV causes an acute inflammatory reaction in the liver that u
Adults (19 years of age and older): The vaccination schedule consists of a primary 1 mL dose administered intramuscularly and a 1 mL booster dose administered intramuscularly 6 to 18 months later. Booster Immunization Following Another Manufacturer’s Hepatitis A Vaccine: A booster dose of VAQTA...
At this writing, inactivated vaccines that offer a safe, convenient, and durably efficacious alternative to the use of immune globulin (IG) are available as pre-exposure prophylaxis against hepatitis A virus (HAV) for both pediatric and adult populations. These vaccines are the medically useful pro...
HCV has a highmutationrate and multiplegenotypes, which have challenged the development of an HCV vaccine. As a result, the primary means of prevention include infection-control practices inhealthcare settings (e.g., sterilization of equipment), the screening and testing of blood and organ donors...
