How likely am I to get shingles?

Around 1 in 4 adults in the UK develop shingles during
their lifetime.1

It is not fully understood why the shingles virus reactivates in some people and
not others, but it is thought to be due to a weaker immune system.

The immune system weakens with age and so the chance of developing shingles
increases as we get older. It is most common and tends to be more severe in people
aged over 70 years.2
