Hepatitis A Live Attenuated Vaccine: What Age Should Children Receive It?

The Hepatitis A live attenuated vaccine is generally recommended for children aged 18 months and older. This vaccine provides long-term immunity against the Hepatitis A virus. It contains weakened forms of the pathogen, which, when dissolved in sterile water, is administered via intramuscular injection, typically in the deltoid muscle.

What to Expect After Vaccination

After receiving the Hepatitis A vaccine, some individuals may experience mild side effects such as fever or allergic reactions. In cases of low-grade or transient fever, it is usually sufficient to monitor the situation, encourage hydration, and allow the body to naturally recover without medical intervention.

When to Seek Medical Attention

However, if a person develops a high fever or severe allergic symptoms, it is important to seek medical attention promptly. A healthcare provider can evaluate whether there are underlying conditions or a more serious allergic response that requires treatment. In rare cases, severe allergic reactions may necessitate antihistamine therapy or other forms of medical care.

Possible Local Reactions at the Injection Site

Some individuals may also experience localized reactions such as swelling, redness, or the formation of a small lump or ulcer at the injection site. These symptoms are more commonly observed in people with a heightened immune response to the vaccine components.

If skin irritation or ulceration occurs, it is advisable to clean the area with an antiseptic like iodine tincture, cover it with a sterile bandage or adhesive dressing, and avoid exposing the area to water. With proper care, these local reactions typically resolve within a short period of time.
