RSV vaccine older adults overview

Overview

RSV (respiratory syncytial virus) is a common virus that usually causes mild cold-like symptoms. But in older adults, especially those with certain health conditions, it can become serious and lead to severe lung infections like pneumonia. The RSV vaccine is a shot that helps protect older adults from getting very sick from RSV. It trains your immune system to fight the virus, reducing the risk of hospitalization and severe illness.

Yes, RSV is very common. Most people get infected before age 2, but you can get it again many times. In older adults, RSV causes about 177,000 hospitalizations and 14,000 deaths each year in the United States alone. The virus is especially common in autumn and winter.

RSV can affect anyone, but older adults—especially those aged 60 and older—are at higher risk of severe illness. People with chronic heart or lung disease (like COPD or heart failure), weakened immune systems, or who live in nursing homes are particularly vulnerable. Healthy older adults can also get very sick from RSV.

Symptoms

Common symptoms

• Runny or stuffy nose
• Cough
• Sneezing
• Sore throat
• Fever
• Headache
• Feeling run down or very tired

Symptoms in older adults

• Worsening of chronic breathing problems like COPD or asthma
• Shortness of breath or difficulty breathing
• Wheezing
• Pneumonia (infection in the lungs)
• Confusion or feeling very unwell
• Worsening of heart failure (e.g., swelling in legs, increased fatigue)

Causes

Main causes

• Infection with respiratory syncytial virus (RSV) – a virus that spreads through drops from coughs or sneezes.
• Touching surfaces with the virus and then touching your eyes, nose, or mouth.

Risk factors

• Age 60 years or older
• Chronic lung disease (COPD, asthma, emphysema)
• Chronic heart disease (heart failure, coronary artery disease)
• Weakened immune system (from illness or medications)
• Living in a nursing home or long-term care facility
• Being a smoker
• Having other chronic conditions like diabetes or kidney disease

When to see a doctor

See a doctor urgently if:

• If you have shortness of breath or trouble breathing
• If you feel very weak, lightheaded, or confused
• If you have a high fever that doesn't come down with usual care
• If your cough gets much worse or you are coughing up yellow or green mucus

Book a routine appointment if:

• If you are 60 or older and haven't received the RSV vaccine yet, talk to your doctor at your next check-up
• If you have mild cold symptoms that last more than a week without improvement
• If you have a chronic condition and are around someone with RSV

Diagnosis

Doctors diagnose RSV based on your symptoms and sometimes with a test. They may ask about your health history and do a physical exam, especially listening to your lungs.

Tests that may be done

• Nasal swab test – a long cotton swab is gently put into your nose to collect mucus. The sample is tested for RSV virus. This is similar to the test for COVID-19 or flu.

What to expect at your appointment

The test is quick and may be a little uncomfortable but usually not painful. Results may come back in a few hours or a day, depending on the clinic. If you have severe symptoms, you might also have a chest X-ray or blood tests to check for pneumonia or other problems.

Treatment

There is no specific medicine to cure RSV. Treatment focuses on relieving symptoms and supporting your body while it fights the virus. Most people recover at home. However, some older adults may need hospital care for oxygen or fluids.

Self-care at home

• Get plenty of rest
• Drink lots of fluids (water, soup, herbal tea) to stay hydrated
• Use a humidifier or steam from a shower to ease coughing
• Take acetaminophen or ibuprofen (as directed by a pharmacist or doctor) for fever or body aches
• Avoid smoking or being around smoke

Medical treatments

If symptoms are severe, especially breathing problems, doctors may give oxygen therapy, fluids through a vein (IV), or breathing treatments like inhalers to open the airways. In very severe cases, you may need to stay in the hospital. Antiviral drugs are not used for RSV in older adults.

Living with this condition

If you have a mild RSV infection, you can usually manage it at home with rest. Stay away from others to avoid spreading the virus. Monitor your symptoms, especially breathing. If your doctor recommends the RSV vaccine, get it even after you recover from an infection, as it may protect you from future severe illness.

Lifestyle tips

• Wash your hands often with soap and water or use hand sanitizer
• Avoid touching your face, especially eyes, nose, and mouth
• Cover your coughs and sneezes with a tissue or your elbow
• Clean high-touch surfaces like doorknobs and phones regularly
• Stay up to date with other vaccines like flu and COVID-19

Diet and exercise

Eat a balanced diet rich in fruits, vegetables, and protein to support your immune system. If you are recovering from RSV, start with light activity like short walks and increase as you feel better. Always listen to your body.

Mental health and emotional wellbeing

Feeling isolated while sick or worried about getting severely ill from RSV can cause stress or anxiety. It's normal to feel this way. Stay connected with friends and family by phone or video chat. If you feel overwhelmed, talk to your healthcare provider.

Prevention

Yes, in many cases. The best way to prevent severe RSV is by getting the RSV vaccine if you are 60 or older. Also, practicing good hygiene like hand washing and avoiding close contact with sick people helps lower your chances of getting the virus.

Vaccines

The RSV vaccine is a single-dose shot recommended for adults aged 60 years and older. It is especially important for those with chronic health conditions or living in long-term care. The vaccine is not a live virus, so it cannot cause RSV. Talk to your doctor to see if it is right for you. You can get it at the same time as the flu vaccine.

Screening programmes

There is no routine screening test for RSV in healthy older adults. Testing is usually only done if you have symptoms and your doctor thinks it might help with treatment decisions.

Complications

If left untreated

• Pneumonia (lung infection that can be life-threatening)
• Worsening of chronic lung disease (COPD, asthma)
• Worsening of heart failure
• Acute respiratory failure (need for a breathing machine)
• Hospitalization, especially for older adults with underlying conditions

Long-term outlook

Most older adults who get RSV recover fully with rest and supportive care, especially if they are otherwise healthy. The RSV vaccine greatly reduces the risk of severe illness and hospitalization. If you do get very sick, early treatment in the hospital can help you recover. Talk to your doctor about the RSV vaccine to protect yourself.
