Flu prevention

Reading time: 3 min

The most effective preventive measure against flu infection are annual vaccinations. The annual flu vaccine is recommended from the age of 6 months onwards. Vaccination reduces the general population’s risk of contracting influenza by 40–60%. If a vaccinated person does catch flu, then they will have milder symptoms.

A new influenza vaccine is made available every autumn because the virus changes every year and so an updated vaccine is released to protect against this year’s prevalent strain of virus. Vaccination helps prevent you from becoming infected and stops the virus spreading through the community.

Who should get vaccinated?

Vaccination is primarily recommended for those people with the greatest risk of developing complications if they become infected with influenza and those who are in frequent contact with others that have a high risk of infection.

Other groups. Those who work in the armed and security forces, firefighters, civil defence, prison officers and medical emergency staff.

Who should not get vaccinated?

Anyone who experiences a severe allergic reaction (angioedema, difficulty breathing, dizziness), hives upon exposure to eggs, can be vaccinated against flu. On the other hand, the flu vaccine is contraindicated in anyone who has presented a severe allergic reaction to the flu vaccine, regardless of the suspected component. Infants under 6 months must not be vaccinated, nor should anyone with an acute fever until they present a full recovery.

Side effects of the Flu vaccine

The most common side effects after vaccination are pain at the injection site and aching muscles. Children may develop fever, malaise and aching muscles. These side effects usually disappear within 48 hours.

Preventive measures for people with the flu

People, and their companions, who have signs or symptoms compatible with some type of respiratory infection that could be transmitted and who visit a healthcare centre (hospitalisation, accident and emergency, day hospital, outpatient clinic, etc.) should take the following preventive measures:
