Pneumonia is an inflammation of the air sacs in the lungs that can be caused by germs, inhaling foreign substances, or drug-resistant bacteria. The pneumonia vaccine is recommended for adults over 50 or 65, depending on the region, and those with certain health conditions. While the vaccine does not protect against all forms of pneumonia, it can reduce the risk of infection and serious complications. In this context, it is important to understand the relationship between the pneumonia vaccine and aspiration pneumonia, a type of pneumonia caused by inhaling foreign substances, such as food or vomit, into the lungs. Research on the effectiveness of pneumonia vaccines, such as PPSV23, in preventing aspiration pneumonia is limited but suggests a potential benefit, especially in older individuals.

What You'll Learn
The pneumonia vaccine is recommended for people over 50
Pneumonia is an inflammation of the air sacs in the lungs, which can fill with fluid and lead to breathing difficulties, fever, chills, and coughing. It can be caused by germs, inhaling food or liquid into the lungs (aspiration pneumonia), or by drug-resistant bacteria in a hospital setting (hospital-acquired pneumonia). The most common type is community-acquired pneumonia, caused by bacteria, viruses, or fungi outside of a healthcare environment.
The CDC also recommends the vaccine for children under 5 and those at any age with certain risk conditions or weakened immune systems. This includes those with diabetes, COPD, heart failure, or other health problems that can increase the risk of aspiration pneumonia.
There are two types of pneumococcal vaccines available in the United States, PCV15 (Vaxneuvance) and PCV20 (Prevnar 20), which protect against 15 and 20 serotypes of the S. pneumoniae bacterium, respectively. These vaccines are delivered intramuscularly and are not made from live or whole bacteria but rather parts of the bacterial shell, triggering a defensive response from the immune system.
The pneumonia vaccine is an important tool to protect against serious illness and reduce the risk of death from pneumonia, which causes tens of thousands of deaths in the US annually.

The vaccine lowers the risk of infection
Pneumonia is an inflammation of the air sacs in the lungs, which can fill with fluid and lead to breathing difficulties. It is most commonly caused by germs but can also be caused by inhaling food or liquid into the lungs, known as aspiration pneumonia.
The pneumonia vaccine can help lower the risk of infection by stimulating the immune system to produce antibodies that can fight off the pneumococcus bacteria. The vaccine contains weakened or dead bacteria that cannot harm the body but can trigger a defensive response from the immune system. This response generates antibodies that remain in the body, ready to fight off any future bacterial infections.
There are two types of vaccines: PCV (Pneumococcal conjugate) and PPV (Pneumococcal polysaccharide). PCV is typically for children and adults with certain risk factors, while PPV is for the elderly and those with health issues that increase their risk of pneumonia. The specific type of vaccine recommended for an individual may depend on their age, health status, and other factors.
The effectiveness of the pneumococcal vaccine in preventing pneumonia has been studied in various populations, including older individuals in Japan and people with certain health conditions. Research suggests that the vaccine can reduce the risk of community-acquired pneumonia and pneumococcal pneumonia.
While the vaccine does not provide absolute protection against all types of pneumonia, it can significantly lower the chances of infection and help prevent serious complications, especially in those with weakened immune systems. It is important to note that the vaccine's effectiveness may vary depending on individual factors and the specific strain of bacteria causing the infection.

It is 97% effective in children who receive four doses
Pneumonia is an inflammation of the air sacs in the lungs, which can fill with fluid and lead to breathing difficulties, fever, chills, and coughing. It is most commonly caused by bacteria, but it can also be caused by viruses or fungi. Aspiration pneumonia, specifically, is caused by inhaling food or liquid into the lungs.
Pneumonia vaccines are prepared using the pneumococcus bacteria. The vaccine contains weakened bacteria that cannot harm the body. When injected, the body's immune system produces antibodies to destroy the pneumococcus bacteria. These antibodies remain in the body, and can help fight off infection if the person is exposed to the bacteria in the future.
There are two types of vaccines: PCV (Pneumococcal conjugate) and PPV (Pneumococcal polysaccharide). PCV is for babies, children who did not get vaccinated earlier, and adults with certain risk factors. PPV is for the elderly and those with health issues that increase their risk of pneumonia.
The pneumonia vaccine is 97% effective in children who receive four doses. This high level of efficacy is important, as pneumonia causes tens of thousands of deaths each year, particularly among older adults. In 2021, over 40,000 people in the U.S. died from pneumonia, and 1.5 million people visited emergency departments for the disease.
While the pneumonia vaccine is highly effective in children, it is also beneficial for older adults with weakened immunity. The vaccine can help prevent serious complications from pneumonia, even if they still get infected. It is recommended that all adults over 50 receive the vaccine, and that those over 65 or with certain health conditions receive the PPV vaccine.
In addition to the pneumonia vaccine, there are other vaccines that can help lower the risk of infections that can become serious in people with pneumonia. These include the influenza (flu) vaccine and the COVID-19 vaccine. Good oral hygiene and limiting the use of sedatives and antihistamines can also help reduce the risk of aspiration pneumonia specifically.

The pneumococcal vaccine protects against meningitis
Pneumonia is an inflammation of the air sacs in the lungs, which can fill with fluid and lead to breathing difficulties, fever, chills, and coughing. It is most commonly caused by bacteria, but it can also be caused by inhaling food or liquid into the lungs, known as aspiration pneumonia.
Pneumonia vaccines protect against the most serious types of pneumonia that often lead to severe illness and death. However, they do not directly prevent aspiration pneumonia. Instead, they are designed to protect against the bacteria that can cause pneumonia, such as Streptococcus pneumoniae, which is responsible for most cases of bacterial pneumonia.
The pneumococcal vaccine, in particular, is highly effective in preventing pneumococcal meningitis, a severe and often lethal form of meningitis caused by Streptococcus pneumoniae. This vaccine is recommended for infants, high-risk children, and adults over 50 or those with certain health conditions.
A study by Whitney et al. found that the pneumococcal conjugate vaccine (PCV7) was 96% effective in preventing pneumococcal disease in healthy children and provided a 96% effectiveness rate against meningitis specifically. The introduction of this vaccine has led to a significant decline in invasive pneumococcal disease among children and adults.
The pediatric heptavalent pneumococcal conjugate vaccine (PCV7) has also had a substantial impact on the incidence of pneumococcal disease in the United States. It protects immunized children and provides herd immunity to non-immunized individuals by reducing the transmission of Streptococcus pneumoniae.
In summary, while the pneumonia vaccine does not directly address aspiration pneumonia, it offers critical protection against the bacteria that cause pneumonia and can lead to severe health complications, including meningitis. The pneumococcal vaccine is especially effective in preventing pneumococcal meningitis and is recommended for individuals who are at high risk or over 50.

Mouth care can help prevent aspiration pneumonia
Pneumonia is an inflammation of the air sacs in the lungs, which can fill with fluid and lead to breathing difficulties, fever, chills, and coughing. It is most commonly caused by germs but can also be caused by inhaling food or liquid into the lungs, known as aspiration pneumonia.
Aspiration pneumonia is a serious condition that primarily affects older individuals, particularly those over 75 or residing in nursing homes or long-term care facilities. It is often associated with a decline in physical activity, bedridden states, and impaired swallowing or coughing abilities. The risk factors for aspiration pneumonia include weakened swallowing muscles due to Alzheimer's disease or other neurological conditions, as well as a compromised immune system resulting from diabetes, COPD, heart failure, or other underlying health issues.
Maintaining good oral hygiene and mouth care is essential for preventing aspiration pneumonia. Proper mouth care helps eliminate harmful bacteria from the mouth, reducing the likelihood of aspirating them into the lungs. This includes regularly brushing teeth, ideally for 2 minutes after breakfast and dinner while sitting upright. Brushing the tongue is also recommended, and for individuals without teeth, gently brushing the gums with a soft toothbrush is suggested.
For those with dentures, it is crucial to remove and clean them with an electric toothbrush and water after meals. Overnight soaking of dentures in a cleaning solution is also advised. Regular dental visits for professional teeth and gum cleaning are important in maintaining oral health. Additionally, limiting or avoiding sedatives and antihistamine medications is recommended, as they can cause dry mouth and increase the risk of aspiration.
While there is no single "best practice" for oral health interventions to prevent aspiration pneumonia in individuals with oropharyngeal dysphagia, intensified oral hygiene instructions, in combination with other strategies, have shown some promising results. Overall, maintaining good oral hygiene and mouth care is a simple yet effective way to reduce the risk of developing aspiration pneumonia, especially in older adults who are more susceptible to this condition.
