Influvac Tetra 2020/2021 Pre Filled Syringe Of 0.5ml Suspension For Vaccine

Influvac Tetra is a vaccine indicated for protection against influenza (flu). It functions by exposing the body to inactivated influenza virus proteins, which prompts the immune system to develop immunity. This vaccine does not treat an existing flu infection.

Administration is via intramuscular injection by a healthcare professional. It is recommended for individuals over six months of age, particularly the elderly and those with chronic health conditions such as diabetes, heart failure, kidney failure, or chronic obstructive pulmonary disease (COPD). Potential mild side effects include headache, muscle pain, weakness, tiredness, bruising, joint pain, sweating, shivering, and localized pain or swelling at the injection site.

These effects are typically transient. Persistent or concerning side effects should be discussed with a doctor. Prior to vaccination, inform your doctor if you have a high temperature or a history of allergic reactions to vaccines.

Interactions with other medications are possible; discuss all current treatments with your doctor. Pregnant or breastfeeding individuals should consult their doctor before vaccination.
