What is RSV, and why does it matter to you?

RSV stands for respiratory syncytial virus. It’s a common virus that infects the lungs and airways, and for most people it causes nothing worse than a cold. But in older adults, and in anyone with an existing lung condition or a weakened immune system, RSV can trigger pneumonia, bronchitis, or a serious flare-up of a condition you already live with — sometimes serious enough to need hospital treatment. It circulates most heavily over winter, but the risk isn’t limited to the colder months.

Who is newly eligible for the RSV vaccine from September 2026?

From 1 September 2026, the NHS is extending eligibility to adults aged 65 to 74 who fall into one of two groups:

• Those with a chronic respiratory disease, such as poorly controlled asthma, chronic bronchitis, or cystic fibrosis
• Those with immunosuppression caused by an illness or its treatment — for example, a blood cancer diagnosis or ongoing chemotherapy

It’s important to be clear about what this doesn’t cover: simply being 65 to 74 doesn’t make you eligible on its own. You need to have one of the specific conditions above as well. If you’re not sure whether a condition you live with qualifies, your GP practice will be able to tell you.

Who was already eligible before this change?

This expansion builds on a programme that already covers a large number of people. Before this change, the RSV vaccine was already available free on the NHS to:

• Everyone aged 75 and over
• All residents in care homes for older adults, regardless of age
• Pregnant women, to help protect newborn babies in their first months

If you’re already 75 or older, or living in a care home, none of this changes anything for you — you should already have been offered the vaccine, and you don’t need to do anything differently in September. If you had the vaccine at 65 to 74 under the new rules, you won’t be asked to have a second dose when you later turn 75; one dose is designed to last.

Why has the NHS expanded eligibility to this group?

The change follows advice from the Joint Committee on Vaccination and Immunisation, which identified that people aged 65 to 74 with certain lung conditions or weakened immunity face a similar risk from RSV to those already covered by the programme. NHS England says the aim is to reach people before they become seriously unwell, rather than treating severe infections after the fact. As Caroline Temmink, NHS England’s Director of Vaccination, put it: “RSV can make people seriously ill, which is why protection for vulnerable groups matters.”

Public Health Minister Sharon Hodgson framed it in similar terms, saying the expansion “protects higher-risk individuals before serious illness occurs.” The UK Health Security Agency’s Dr Conall Watson added that “the vaccine provides excellent protection against severe lung infection” — reflecting how the existing rollout to over-75s and pregnant women has performed since it began in 2024.

How do you get the RSV vaccine if you’re eligible?

From 1 September 2026, you’ll be able to get the vaccine through your GP practice or a participating high street pharmacy. GP practices are expected to contact everyone on their list who qualifies, but if you have a relevant condition and haven’t heard anything by mid-September, it’s worth contacting your surgery yourself rather than waiting for a letter that may be delayed. The vaccine used, Abrysvo, is given as a single injection and can be had at the same time as a COVID-19 vaccine if you’re also due one. It isn’t routinely given alongside the annual flu jab, so don’t be surprised if your practice books it as a separate appointment.

What if you don’t have one of the listed conditions?

If you’re between 65 and 74 and don’t have a chronic respiratory condition or immunosuppression, you won’t be called for the RSV vaccine yet — the general 65-to-74 population isn’t included in this expansion. That’s not a reason to worry; it simply reflects where the current evidence shows the greatest benefit. You’ll become eligible automatically once you turn 75, alongside everyone else in that age group. In the meantime, the usual advice on avoiding respiratory infections — washing your hands regularly, keeping rooms ventilated, and staying away from other people when you have cold or flu-like symptoms — still applies to everyone.

Why does hot weather become more dangerous as we age?

It’s not just your imagination — hot weather is genuinely harder to cope with in your 50s, 60s, and beyond than it was when you were younger. Several things change as we age that make the body less efficient at dealing with heat.

Your sweat glands become less effective, so your body produces less sweat — and sweating is your primary cooling mechanism. Your circulation also slows, meaning warm blood doesn’t move as efficiently from your core to your skin where heat can escape. And critically, your sense of thirst becomes blunted, so you may not realise you’re dehydrating until it’s already a problem.

People living with heart disease, diabetes, kidney problems, or dementia face added risk in hot weather. The UK Health Security Agency updated its hot weather guidance on 23 June 2026, specifically urging people over 55 to take summer heat seriously and not to dismiss warning signs as simply “feeling a bit tired.”

How much should I be drinking in hot weather?

The NHS recommends at least 6–8 glasses of fluid a day in normal conditions. In warm or hot weather, you need more — aim for around 2 litres throughout the day, and a little extra if you’ve been active or if it’s a particularly hot day.

The golden rule is don’t wait until you’re thirsty. By the time thirst kicks in, you’re already mildly dehydrated. Instead, build drinking into your routine: a glass when you wake up, one with each meal, and one mid-morning and mid-afternoon.

• Good choices: water, diluted squash, lower-fat milk, herbal teas (hot or cold)
• Hydrating foods: cucumber, melon, strawberries, tomatoes, and yoghurt are all high in water content
• Limit alcohol: it’s a diuretic — you lose more fluid than you take in
• Moderate caffeine: tea and coffee are fine in moderation, but don’t rely on them as your main fluid source

How can I keep my home cool without air conditioning?

Most UK homes don’t have air conditioning — but there are effective ways to stay cool without it. Think of your home like a thermos flask: the goal is to trap cool air in and keep hot air out during the day, then reverse that at night.

• Close curtains and blinds on sunny sides during the day. South- and west-facing windows let in the most heat. This single step can drop indoor temperatures by several degrees.
• Open windows at night when the outside air cools — usually from around 9–10pm onwards — to let the heat out and cool air in.
• Move downstairs during the day if possible. Heat rises, so ground-floor rooms stay cooler.
• A damp flannel on your wrists and neck cools you quickly because the blood vessels there are close to the surface.
• Avoid using the oven during the hottest part of the afternoon — cook earlier in the day or prepare cold meals instead.

What are the signs of heat exhaustion — and when should I call for help?

Heat exhaustion is serious but treatable if caught early. Heatstroke — the next stage — is a medical emergency. It’s worth knowing the difference before summer really gets going.

Heat exhaustion typically involves: heavy sweating, dizziness or feeling faint, nausea, headache, pale and clammy skin, and a fast but weak pulse. If you or someone you know has these symptoms, move to a cool room, sip cold water slowly, and apply cool damp cloths to the skin. If symptoms don’t improve within 30 minutes, call NHS 111.

Heatstroke is more alarming: confusion or slurred speech, a very high temperature (above 40°C), stopping sweating despite the heat, a rapid strong pulse, and possible loss of consciousness. This is a 999 emergency — do not wait.

Which medicines can make me more vulnerable to the heat?

This is something many people don’t know, and it’s worth a conversation with your GP or pharmacist before the hottest weeks arrive. A number of very common medicines affect how your body handles heat:

• Diuretics (“water tablets” such as furosemide) increase fluid loss through urine, raising dehydration risk significantly
• Beta-blockers (bisoprolol, atenolol, and others) can limit your heart’s ability to respond to heat
• Antihistamines — including common hay fever tablets — can reduce sweating, impairing your cooling system
• Antidepressants and antipsychotics affect temperature regulation in different ways depending on the type
• Blood pressure medications can interact with the dilation of blood vessels caused by heat, sometimes leading to dizziness or falls

Never stop taking medication without speaking to your doctor first — but do raise the subject. Asking your GP “do any of my medicines affect how I handle hot weather?” is a completely reasonable and sensible question.

How can I look out for a neighbour or friend during a heatwave?

One of the most valuable things you can do during hot weather is look out for others — especially people who live alone, have limited mobility, or rarely leave the house. Isolation and heat are a dangerous combination, and NHS guidance consistently highlights social connection as one of the best protections against heat-related harm.

A quick phone call or knock on the door can genuinely make a difference. If you visit in person, keep an eye on a few simple things:

• Is there water nearby — and have they actually been drinking it?
• Is the room uncomfortably warm? Are curtains drawn on the sunny side?
• Do they seem confused, more tired than usual, or unsteady on their feet?
• Are they wearing light, loose clothing?

You don’t need to be a formal carer to do this. Being a neighbour is enough.
