Influenza is more than a bad cold. It can mean a week of fever, body aches and exhaustion, and for some people it leads to pneumonia or hospitalisation. Flu vaccinations are the most effective way to reduce that risk.
How Do Flu Vaccinations Work?
A flu vaccine trains your immune system to recognise influenza viruses before you meet them. Antibodies take about two weeks to develop, so it is best to get vaccinated before flu season peaks. Because the virus changes every year and protection fades over time, you need a fresh dose annually.
Who Should Get Vaccinated?
Most health authorities recommend a yearly flu vaccination for everyone aged six months and older. It is especially important for:
- Adults aged 65 and over
- Pregnant women
- Young children
- People with asthma, diabetes, heart or kidney disease
- Healthcare workers and caregivers
When Is the Best Time to Get One?
In the Northern Hemisphere, the ideal window is September to late October. If you miss it, getting vaccinated later in the season is still worthwhile.
How Effective Are They?
Effectiveness changes from year to year, but flu vaccinations consistently lower the chance of catching the flu, reduce how severe it is, and cut the risk of hospitalisation.
Side Effects and Myths
Side effects are usually mild: a sore arm, slight fever, headache or tiredness for a day or two. Serious allergic reactions are very rare.
The biggest myth is that the flu shot gives you the flu. The injectable vaccine contains no live virus, so it cannot cause influenza.
Where Can You Get Vaccinated?
Flu shots are available at clinics, pharmacies, hospitals and many workplaces. For more health and prevention tips, visit Earlsdon Pharmacy
