Shingles is caused by reactivation of the chickenpox virus and can lead to a painful rash and, in some people, long-lasting nerve pain called postherpetic neuralgia. The modern recombinant shingles vaccine is given as two doses and offers strong, durable protection.
It is generally recommended from age 50, and in some programmes from 60 or 65. Adults aged 18 and over who have weakened immune systems, for example from certain illnesses or treatments, may also be eligible and are often a priority because their risk is higher.
You can usually have the vaccine even if you have had shingles before, since recurrences are possible. If you previously received an older live shingles vaccine, the newer one may still be recommended. Ask a doctor or pharmacist about your eligibility, timing, and whether to delay around any immune-suppressing treatment.
