INFLUVAC TETRA

About

Influvac Tetra is a quadrivalent influenza vaccine designed to provide active immunization against four strains of influenza virus: two influenza A subtype viruses and two influenza B lineage viruses. This vaccine works by stimulating the body's immune system to produce antibodies against these specific viral strains. When exposed to the actual influenza virus, these antibodies help to neutralize the virus, preventing infection or significantly reducing the severity of the illness. It is crucial for preventing seasonal influenza and its associated complications, especially in individuals at higher risk, such as the elderly, young children, pregnant women, and those with underlying chronic medical conditions. Regular annual vaccination is recommended due to the evolving nature of influenza viruses and the waning of vaccine-induced immunity over time, ensuring continuous protection against the most prevalent strains.

Uses

• Prevention of seasonal influenza (flu).
• Active immunization against specific influenza A and B virus strains.
• Vaccination for individuals aged 6 months and older.
• Reduction of influenza-related complications, hospitalizations, and mortality.

Directions For Use

Administered by a healthcare professional as a single dose via intramuscular injection, typically into the deltoid muscle for adults and older children, or the anterolateral thigh for infants.

Benefits

• Provides broad protection against four influenza virus strains.
• Significantly reduces the risk of developing severe influenza illness.
• Helps prevent influenza-related hospitalizations and complications.
• Minimizes the spread of influenza within communities.
• Suitable for a wide range of age groups, including children and the elderly.
• Contributes to overall public health by reducing disease burden.

Side Effects

• Pain at the injection site
• Redness or swelling at the injection site
• Headache
• Muscle aches (myalgia)
• Fatigue or tiredness
• Low-grade fever
• Nausea
• Dizziness
• Sweating
• Shivering
• Joint pain (arthralgia)
• Rarely, allergic reactions (e.g., rash, itching, difficulty breathing)

Safety Measures

• Alcohol - Generally, alcohol does not directly interact with the influenza vaccine. However, excessive alcohol consumption can weaken the immune system, potentially affecting vaccine efficacy or masking mild post-vaccination side effects.
• Pregnancy - Influenza vaccination is highly recommended for pregnant women at any stage of pregnancy. It is considered safe and effective, protecting both the mother and the newborn from influenza and its potential severe complications.
• Breastfeeding - Influenza vaccination is safe and recommended for breastfeeding mothers. It provides protection to the mother and can also transfer protective antibodies to the infant through breast milk, offering passive immunity.
• Liver - No specific contraindications for individuals with stable liver conditions. The vaccine is generally safe; however, patients with severe or decompensated liver disease should consult their physician.
• Kidney - No specific contraindications for individuals with kidney conditions. The vaccine is generally safe for those with stable kidney disease, including patients undergoing dialysis.
• Lung - Individuals with chronic lung conditions (e.g., asthma, COPD, cystic fibrosis) are at increased risk for severe influenza complications, making vaccination highly recommended and generally safe for them.
