Who should have it
Anyone who wants to reduce their risk of flu, and especially those more likely to become seriously unwell, such as older adults, pregnant women, and people with certain long term health conditions. It’s also worth considering before travel, particularly for pilgrimages, cruises, or other crowded trips, and when visiting regions during their flu season.
How many doses
A single dose each year provides protection for that flu season. Because the virus changes and immunity fades over time, a new vaccination is needed each year. Your prescriber or pharmacist will confirm the right vaccine for you.
Possible side effects
Side effects are usually mild and may include soreness, redness or swelling at the injection site, headache, aching muscles, tiredness, or a mild temperature for a day or two after vaccination.
Additional precautions
Vaccination is the main protection, but good habits help too. Wash your hands regularly, catch coughs and sneezes in a tissue, and avoid close contact with others while unwell. In crowded travel settings, these simple steps further reduce your risk.
About the disease
Seasonal flu is a viral infection of the airways that tends to circulate in the colder months. For many people it means a week of feeling unwell with fever, aches and tiredness, but it can lead to more serious illness, especially in those who are older or have underlying health conditions, which is why yearly vaccination is encouraged.
