Pneumococcal vaccine adults

Overview

Pneumococcal disease is an infection caused by bacteria called Streptococcus pneumoniae. It can lead to serious illnesses like pneumonia (lung infection), meningitis (infection of the lining of the brain and spinal cord), and sepsis (blood infection). The pneumococcal vaccine helps protect adults from these dangerous infections.

Pneumococcal infections are a common cause of serious illness, especially in older adults and people with underlying health problems. Vaccination has made these infections much less common.

Pneumococcal disease can affect anyone, but it is most serious in adults over 65, young children, and people with chronic health conditions or weakened immune systems.

Symptoms

Common symptoms

• High fever and chills
• Cough, often with phlegm
• Difficulty breathing or fast breathing
• Chest pain that gets worse when you breathe deeply or cough
• Confusion or disorientation (especially in older adults)
• Headache and stiff neck (may indicate meningitis)

Symptoms in children

• High fever
• Cough and rapid breathing
• Irritability or crying more than usual
• Poor feeding or vomiting
• Lethargy (unusually sleepy or hard to wake)

Symptoms in older adults

• Fever and chills (may be less noticeable)
• Confusion or sudden change in mental state
• Cough and shortness of breath
• Loss of appetite and weakness
• Falling or dizziness

Causes

Main causes

• Infection with the bacterium Streptococcus pneumoniae (pneumococcus)
• The bacteria spread through droplets when an infected person coughs or sneezes
• Pneumococcus can live in the nose and throat of healthy people without causing illness, but it can cause infection if it spreads to other parts of the body

Risk factors

• Age 65 years or older
• Chronic diseases such as heart disease, lung disease (like COPD), liver disease, kidney disease, or diabetes
• Weakened immune system (from cancer, HIV, organ transplant, or long-term steroid use)
• Smoking or heavy alcohol use
• Living in a long-term care facility or being hospitalized
• Having had your spleen removed or having a damaged spleen

When to see a doctor

See a doctor urgently if:

• If you have trouble breathing, chest pain, or severe headache with stiff neck

Book a routine appointment if:

• If you are 65 or older and have not had the pneumococcal vaccine, ask your doctor about getting vaccinated
• If you have a chronic health condition or weakened immune system, discuss vaccination with your healthcare provider
• If you are unsure about your vaccination status or past shots

Diagnosis

Pneumococcal disease is diagnosed by a healthcare provider based on your symptoms, a physical examination, and tests. The vaccine itself does not require diagnosis—it is given to prevent infection.

Tests that may be done

• Blood tests to check for signs of infection and identify the bacteria
• Chest X-ray to look for pneumonia
• Lumbar puncture (spinal tap) if meningitis is suspected
• Sputum culture (testing phlegm) to find the bacteria

What to expect at your appointment

If you have symptoms of pneumococcal disease, your doctor will likely order tests to confirm the cause. Treatment may start right away with antibiotics, even before test results are back. Most people recover with proper care, especially if they are otherwise healthy and are treated early.

Treatment

Pneumococcal infections are treated with antibiotics to kill the bacteria. The specific antibiotic depends on the severity and type of infection. For severe cases, hospitalization may be needed for intravenous (IV) antibiotics and supportive care such as oxygen or fluids. Prevention through vaccination is the best approach.

Self-care at home

• Get plenty of rest and stay hydrated if you have a mild infection
• Take over‑the‑counter fever reducers (like paracetamol or ibuprofen) as directed by your doctor or pharmacist
• Monitor your symptoms closely and seek medical help if they worsen

Medical treatments

Antibiotics are the main treatment for pneumococcal disease. Your doctor will choose an antibiotic based on the type of infection and your health history. In hospital settings, you may receive intravenous antibiotics, oxygen therapy, or other supportive treatments. Always follow your healthcare provider’s instructions and complete the full course of antibiotics, even if you start to feel better.

When is surgery considered?

Surgery is rarely needed for pneumococcal disease. In some serious cases, such as an abscess (pocket of pus) in the lung or around the brain, a drainage procedure or surgery may be necessary.

Living with this condition

After vaccination, you can continue your normal daily activities. The vaccine greatly reduces your risk of getting pneumococcal disease, but it is still important to practice good hygiene, such as washing your hands often and covering your mouth when you cough.

Lifestyle tips

• Stay up to date with recommended vaccines, including influenza and COVID‑19 vaccines, to reduce overall infection risk
• Avoid smoking and limit alcohol intake to strengthen your immune system
• Manage chronic conditions like diabetes or heart disease with your healthcare team

Diet and exercise

A healthy diet rich in fruits, vegetables, whole grains, and lean protein supports your immune system. Regular physical activity, such as walking or swimming, can also help keep your body strong and reduce the risk of infections.

Mental health and emotional wellbeing

Dealing with a serious infection can be stressful and may affect your mental health. It is normal to feel anxious or worried. Talk to your doctor or a mental health professional if you are struggling. Remember that vaccination gives you powerful protection.

Prevention

Yes, pneumococcal disease can largely be prevented through vaccination. The vaccine is safe and effective. In addition, maintaining a healthy lifestyle and good hygiene (like washing hands) can reduce the spread of bacteria.

Vaccines

There are different types of pneumococcal vaccines. Your doctor will recommend the one that is appropriate for your age and health. For most adults, one or two doses are given. Talk to your healthcare provider about when you should get vaccinated.

Screening programmes

There is no routine screening test for pneumococcal disease. The best prevention is vaccination, especially for people at higher risk.

Complications

If left untreated

• Pneumonia that leads to respiratory failure or sepsis
• Meningitis causing brain damage or hearing loss
• Sepsis (blood infection) that can cause organ failure and death
• Empyema (pus in the space around the lungs)
• Pericarditis (inflammation around the heart)

Long-term outlook

With prompt treatment, most people recover fully from pneumococcal disease. The outlook is excellent for those who are vaccinated and otherwise healthy. For older adults and those with chronic conditions, vaccination dramatically lowers the risk of severe complications. If you have any concerns, talk to your healthcare provider—they can help you stay protected.
