Shingles and the Shingles Vaccine

Shingles is a strange and painful illness: a rash caused by a virus that most people first met in childhood as chickenpox, and which can lie dormant in the body for decades before reawakening. For some, it is a few weeks of discomfort; for others, it leaves lasting nerve pain. With an effective vaccine now widely available, much of that suffering is preventable, which makes shingles a topic worth understanding before it strikes.

This is a companion piece for people curious about shingles and its vaccine. It is not medical advice. It is an honest overview, and it is no substitute for the guidance of a clinician or pharmacist about your own situation.

What shingles is

Shingles is caused by the reactivation of the same virus that causes chickenpox, which stays in the body after the childhood infection and can flare up later in life, often when the immune system is weakened by age, stress, or illness. It typically causes a painful, blistering rash, usually on one side of the body or face, often preceded by tingling or burning. The pain can be significant, and the rash usually heals over a few weeks. It becomes more common with age, which is part of why prevention focuses on older adults.

The risk of lasting nerve pain

The complication people most want to avoid is postherpetic neuralgia, in which nerve pain persists long after the rash has gone, sometimes for months or years, and can be severe and difficult to treat. This kind of lingering nerve pain connects to the wider experience our companion piece on low-dose naltrexone touches on for chronic pain. Like other illnesses with long tails, such as the one our companion piece on long COVID describes, shingles can affect people well beyond the initial infection. The risk of this complication rises with age, which raises the stakes of prevention.

The vaccine and getting care

A highly effective shingles vaccine is now available and is recommended for older adults and some others at higher risk in many countries, substantially reducing the chance of getting shingles and of the lasting nerve pain that can follow. People are encouraged to ask their doctor or pharmacist whether they are eligible. If shingles does develop, starting antiviral treatment promptly, ideally within a few days of the rash appearing, can help, so recognising it early and seeking care quickly matters; our companion piece on how to be heard by your doctor may help in getting timely attention. None of this is a prescription for you; it is the ground others explore with professional advice.

Worth preventing

What makes shingles notable is that a genuinely unpleasant, sometimes lasting illness is now substantially preventable. For older adults in particular, asking about the vaccine is a simple, worthwhile conversation. And for anyone who develops the telltale rash, acting quickly to seek treatment can make a real difference. It is one of those cases where a little foresight can spare a lot of pain.
