Seasonal vaccines: what to get, and when

Flu jab

Best taken before flu circulates. Free on the NHS for eligible groups, and available privately from many clinics.

COVID-19 booster

Offered to eligible groups in NHS seasonal campaigns, with private boosters available year-round.

RSV vaccine

A newer UK programme protecting older adults and newborns (via vaccination in pregnancy). Check NHS eligibility.

When should I get my flu jab?

In the UK the flu vaccine is usually offered from early autumn. Getting it before flu starts circulating — typically by early winter — gives your body time to build protection. Private flu jabs are available year-round.

Is the flu vaccine worth it?

Flu vaccination lowers your risk of catching flu and of becoming seriously ill if you do. Effectiveness varies year to year depending on how well the vaccine matches circulating strains; UKHSA publishes UK figures each season. Speak to a clinician about what is right for you.

Can I have the flu and COVID-19 vaccines at the same time?

In many cases yes — they are often offered together during NHS seasonal campaigns. A clinician will confirm what is appropriate for you.

How long does the flu vaccine take to work?

It typically takes around 10 to 14 days to build full protection, which is why getting vaccinated before winter is recommended.

Who can get the RSV vaccine?

The UK has an RSV vaccination programme for older adults (around age 75) and during pregnancy to protect newborns. Eligibility is set by the NHS — check the latest NHS guidance.
