What is the correct dosage for Hepatitis A for those aged 19 and older?

The correct dosage for Hepatitis A vaccination for individuals aged 19 and older is 1.0 mL. This dosage is established based on various studies and guidelines for immunization practices, which recommend a standard dosage in order to ensure effective immunization against the virus. A 1.0 mL dose is typically administered intramuscularly and is designed to provide sufficient immune response for individuals in this age group.

In contrast, lower dosage options are generally intended for specific populations, such as pediatric patients, who have different immunological requirements. Therefore, understanding the correct dosage helps ensure that individuals receive an adequate and effective vaccination, ultimately contributing to better health outcomes and protection against Hepatitis A.
