The flu, caused by the influenza virus, is a contagious illness spread through respiratory droplets from sneezing, coughing, or even talking. Symptoms can range from mild to severe and typically include fever, cough, headache, body aches, and fatigue, often lasting up to a week. While most people recover fully, some may experience prolonged fatigue or more severe complications, such as pneumonia. In Ireland, the HSE reports that between 200 and 500 people die from flu-related complications annually.
Who is at Risk?
While anyone can catch the flu, certain groups are more vulnerable to complications:
- People aged 65 and over
- Pregnant women
- Individuals with long-term health conditions, including cancer, lung, kidney, heart, or neurological diseases
- Those with weakened immune systems (e.g., chemotherapy patients, people with diabetes)
- People with obesity (BMI over 40)
- Residents of nursing homes or long-term care facilities
- People with Down Syndrome
- Children with moderate to severe neurodevelopmental disorders (e.g., cerebral palsy)
- Healthcare workers, carers, and those in close contact with at-risk individuals
- Anyone with regular contact with poultry, waterfowl, or pigs
What is the Flu Vaccine?
The flu vaccine is a seasonal vaccination recommended to be administered in September or October. The vaccine prompts the body to produce antibodies that help fight the flu virus, often making symptoms milder and shorter if you do contract the flu.
Each year, the flu vaccine is updated to match the circulating strains, so it’s important to get vaccinated annually. For adults, the vaccine is administered as an injection in the upper arm. Side effects are generally mild and may include slight swelling or a mild fever, which can be treated with an ice pack or paracetamol.
There is also a new nasal spray flu vaccine (Fluenz Tetra) available in Ireland for children aged 2 to 18, offering needle-free protection.
Why Get Vaccinated During the COVID-19 Pandemic?
As COVID-19 continues to strain healthcare resources, it’s especially crucial to reduce flu cases and keep hospital admissions lower. The flu vaccine helps prevent flu-related hospitalizations but does not protect against COVID-19, as the two are caused by different viruses.
Who is Eligible for a Free Flu Vaccine?
The flu vaccine is free for:
- People over 65
- Anyone in the at-risk groups listed above
- Individuals in close contact with people at risk, including carers
- Children aged 2 to 12, who can receive the nasal spray vaccine free of charge, regardless of risk group status
