Fluvirin

Fluvirin is a vaccine used to protect against influenza, commonly known as the flu. It is an inactivated influenza vaccine, meaning it contains killed virus particles that stimulate the body's immune response without causing the disease. Fluvirin is typically administered via intramuscular injection.

Composition

Fluvirin contains antigens from two influenza A virus subtypes and one influenza B virus strain. The specific strains included in the vaccine are updated annually based on recommendations from the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) to match the most prevalent strains expected during the upcoming flu season.

Indications

Fluvirin is indicated for active immunization against influenza in individuals aged 4 years and older. It is particularly recommended for high-risk groups, including:

• Elderly individuals
• Pregnant women
• Healthcare workers
• Individuals with chronic medical conditions such as asthma, diabetes, and heart disease

Administration

The vaccine is administered as an intramuscular injection, typically in the deltoid muscle of the upper arm. For children aged 4 to 8 years who have not previously been vaccinated, two doses may be required, administered at least four weeks apart. For individuals aged 9 years and older, a single dose is usually sufficient.

Side Effects

Common side effects of Fluvirin include:

• Soreness at the injection site
• Fever
• Fatigue
• Headache
• Muscle aches

Severe allergic reactions are rare but can occur. Individuals with a history of severe allergic reactions to any component of the vaccine or to a previous dose of any influenza vaccine should not receive Fluvirin.

Storage

Fluvirin should be stored in a refrigerator at temperatures between 2°C and 8°C (36°F and 46°F). It should not be frozen. The vaccine should be used before the expiration date indicated on the packaging.
