Influenza Vaccine
Influenza (flu) is caused by the influenza virus, which affects the respiratory system. Common symptoms include high fever, headache, fatigue, and body aches. In some cases, the illness can become severe and require hospitalization. Even after recovery, fatigue may persist for several weeks. Therefore, vaccination plays a key role in prevention.
Is the influenza vaccine safe?
The influenza vaccine is made from inactivated (killed) virus, meaning it cannot cause the disease. It is considered highly safe and effective in preventing influenza. However, vaccination may not guarantee complete protection, but symptoms are usually much milder if infection occurs.
What are the side effects after vaccination?
Common side effects include redness or swelling at the injection site, mild fever, or body aches. These symptoms usually resolve on their own within 2–3 days.
Who should get the influenza vaccine and when?
- Vaccination is recommended for individuals aged 6 months and older, once a year. It can be administered year-round, but is especially recommended before the rainy season (March–May) or before the winter season (October–November).
- Children under 9 years old receiving the vaccine for the first time should receive 2 doses, spaced 1 month apart. After that, annual vaccination is recommended with a single dose.
Contraindications
- Children younger than 6 months
- Individuals with severe egg allergy, as the vaccine is produced using egg-based technology
- Individuals who have had a severe allergic reaction to a previous influenza vaccine
- Individuals with fever, acute illness, or uncontrolled chronic conditions should postpone vaccination
Prevention of Influenza
- Receive the influenza vaccine annually
- Avoid close contact with infected individuals
- Wash hands regularly with soap and water, or use alcohol-based hand sanitizer if unavailable
- Avoid touching the eyes, nose, and mouth, as the virus can spread through these entry points
- Wear a face mask when appropriate
