INTRODUCTION

Pneumonia is a common illness that can be serious or even life-threatening. Not all cases of pneumonia can be prevented, but taking certain measures can help. To help prevent pneumonia, you should:

Get vaccinated

Stop smoking

Wash your hands

Lead a healthy lifestyle, including eating a healthy diet and exercising regularly

This topic reviews the benefits of pneumonia vaccines, who should receive them, and other ways to help prevent pneumonia. Information on the symptoms and treatment of pneumonia is provided separately. (See "Patient education: Pneumonia in adults (Beyond the Basics)".)

PNEUMONIA VACCINES

Pneumonia can be caused by a number of different bacteria, viruses, or other infecting organisms (germs). Vaccines that protect against two major causes of pneumonia are available: pneumococcal vaccines and influenza vaccines. Vaccines that protect against some of the less common causes of pneumonia, such as the pertussis vaccine, are also available. When appropriate, getting vaccinated and encouraging others around you to do the same are the best ways to prevent pneumonia.

Pneumococcal vaccines — Pneumococcal vaccines provide protection against pneumococcus (also known as Streptococcus pneumoniae), which is one of the most common bacterial causes of pneumonia in adults.

There are many different types of pneumococci. Pneumococcal vaccines protect against the most common types by stimulating the production of antibodies (proteins that the immune system makes) that help to fight off infection. Vaccination reduces the number of people who get pneumonia and makes disease less severe in those who do get it.

Types of pneumococcal vaccines — Two kinds of pneumococcal vaccine are available in the United States. These vaccines have different properties that make them appropriate for different populations:

PPSV23 (pneumococcal polysaccharide vaccine) is generally used in adults and protects against 23 types of pneumococcus. PPSV23 is not effective in infants and children under two years old.

PCV13 (pneumococcal conjugate vaccine) was developed for use in infants and children. It protects against 13 types of pneumococcus. Because PCV13 stimulates a protective immune response in both adults and children, PCV13 is given in addition to PPSV23 in adults who are at high risk for serious pneumococcal infection (see below).

Who needs vaccination? — Vaccination is particularly important for adults who are 65 or older, smokers, people with weakened immune systems, and people who have certain chronic illnesses. Specific vaccination recommendations vary by age and other factors. Your doctor or nurse can talk to you about what is most appropriate for your situation.

Vaccination with PPSV23 is recommended for all adults 65 years or older and any adult (over the age of 18) who smokes or has one or more of the following chronic illnesses:

Chronic heart disease, including congestive heart failure and cardiomyopathy (but not including high blood pressure)

Chronic lung disease, including asthma and chronic obstructive pulmonary disease (COPD)

Diabetes mellitus

Alcoholism

Chronic liver disease

Vaccination with both PCV13 and PPSV23 is recommended for all adults who are at high risk for serious pneumococcal infection. People considered high risk include those with one more of the following conditions:

Age 65 years older with one or more of the chronic illnesses outlined above or active smoking

Cerebrospinal fluid leak

Cochlear implant

Poor function of the spleen (this includes people who have had their spleen removed and those with sickle cell disease or another disorder that causes spleen damage)

HIV infection

Chronic kidney failure

Nephrotic syndrome

Leukemia

Lymphoma, including Hodgkin disease

Multiple myeloma

Metastatic cancer (cancer that has spread beyond the original location)

Organ transplantation

An immune system that is weaker than normal, such as with congenital or acquired immunodeficiencies or the use of immunosuppressive medications (including long-term steroid use and radiation therapy)

Vaccination with both PCV13 and PPSV23 is also reasonable for any adult 65 years or older and people with a history of invasive pneumococcal infection, such as meningitis or a bloodstream infection.

When both vaccines are needed, PCV13 should be given first. PPSV23 is typically given about eight weeks after PCV13, except in adults 65 and older who have none of the chronic illnesses or high-risk conditions outlined above. For these patients, a one-year interval between PCV13 and PPSV23 is advised. If PPSV23 has already been given, waiting one year before giving PCV13 is advised.

Both pneumococcal vaccines are safe for pregnant women.

Who needs revaccination — Adults under 65 years old with poor spleen function or those with other conditions that affect the immune system should receive a second dose of the PPSV23 vaccine about five years after the first dose. Revaccination with PCV13 is not recommended.

Influenza vaccines — Influenza (flu) vaccine reduces the risk of pneumonia caused by the influenza virus. They can also help to prevent pneumococcal pneumonia or pneumonia caused by other bacteria, which can occur as a complication of influenza. Yearly influenza vaccine (the "flu shot") is recommended for everyone over the age of six months. This vaccine is especially important for those who are at high risk for pneumonia; this is because pneumonia is the most common serious complication of the flu.

The flu vaccine changes from year to year and is most likely to protect you if you get it as soon as it becomes available (usually by October in the northern hemisphere and May in the southern hemisphere). Nevertheless, it can still protect you if you get it later in the season and at any time during the influenza season (usually between October and April in the United States). (See "Patient education: Influenza prevention (Beyond the Basics)".)

Other vaccines — Vaccines that protect against less common causes of pneumonia include vaccines for pertussis (whooping cough), Haemophilus influenza type B (Hib), measles, and varicella (chickenpox). Ensuring that you and those around you are up to date on recommended vaccines can help prevent pneumonia in you, your family, and your community. The exact recommended schedule for vaccinations varies by age. (See "Patient education: Vaccines for adults (The Basics)" and "Patient education: Vaccines for babies and children age 0 to 6 years (The Basics)" and "Patient education: Vaccines for children age 7 to 18 years (Beyond the Basics)".)

QUITTING SMOKING

Smoking weakens your resistance to pneumonia by causing damage to your lungs. Quitting smoking and avoiding secondhand smoke exposure is another important way to help prevent pneumonia and improve your overall health. (See "Patient education: Quitting smoking (The Basics)" and "Patient education: Quitting smoking (Beyond the Basics)".)

HAND HYGIENE

Washing your hands with soap and water or using an alcohol-based hand sanitizer is one of the most important ways to avoid getting sick and spreading illness to others, particular when you have a viral infection such as influenza. Because pneumonia is spread by contact with infected respiratory secretions (tiny droplets that can travel through the air), exposure to someone who has pneumonia increases the risk for infection. People who have pneumonia should cover their mouths and nose when coughing or sneezing, dispose of used tissues immediately, and wash their hands. Sneezing or coughing into the sleeve of one's clothing (at the inner elbow) is another way to keep saliva and secretions from spreading to others; it also has the advantage of keeping the hands clean.

HEALTH MAINTENANCE

Living a healthy lifestyle including eating right, exercising, and maintaining a healthy weight can help prevent many health problems. Taking medicines as prescribed, particularly for chronic illnesses that increase the risk of pneumonia, can also help prevent health complications. (See "Patient education: Diet and health (Beyond the Basics)" and "Patient education: Preventive healthcare for older adults (The Basics)".)
