When Was Pneumonia Vaccine Invented?

The Discovery of Germs and Pneumonia

Before the 19th century, the cause of infectious diseases was largely unknown. It was not until the late 1800s that scientists began to understand the existence of germs and their role in the spread of illness. In 1881, the bacteria responsible for causing pneumonia, Streptococcus pneumoniae, was identified.

Pneumonia is a serious respiratory infection that affects the lungs. It can be caused by different types of bacteria, viruses, or fungi, but Streptococcus pneumoniae is the most common cause of bacterial pneumonia.

The Development of Pneumonia Vaccines

In the 20th century, research on vaccines accelerated and focused on protecting people against infectious diseases. The first successful vaccine was developed for smallpox in the late 1700s, and the first vaccine for rabies was developed in 1885.

Researchers began working on developing a vaccine for pneumonia in the 1930s. In the 1940s, the first pneumonia vaccine was created using a killed form of the bacteria that causes pneumonia. However, this vaccine was not widely available.

In the 1970s, a more effective pneumonia vaccine was developed. This vaccine used a purified form of the bacteria’s polysaccharide capsule to stimulate an immune response in the body. This vaccine was called the Pneumococcal Polysaccharide Vaccine (PPV). PPV protected against 23 strains of the Streptococcus pneumoniae bacteria.

The Introduction of PCV13

In 2000, a new vaccine was developed called the Pneumococcal Conjugate Vaccine (PCV). This vaccine worked differently than previous pneumonia vaccines. PCV used a protein from the bacteria’s surface to stimulate an immune response. This allowed the vaccine to protect against more strains of the bacteria than previous vaccines.

In 2010, an updated version of PCV was introduced called PCV13. This vaccine protects against 13 strains of the Streptococcus pneumoniae bacteria. It is now recommended for children and adults over the age of 65, as well as those who are at higher risk of developing pneumonia.

PCV13 is considered safe and effective for most people. However, like all vaccines, it may cause side effects such as pain or redness at the injection site, fever, or headache.

The invention of the pneumonia vaccine has been instrumental in reducing the number of deaths and hospitalizations due to pneumonia. By protecting against the bacteria that causes pneumonia, vaccines have saved countless lives. The development and improvement of pneumonia vaccines have changed the way we think about and protect against infectious diseases.

The creation of websites has come a long way since the invention of the internet. It now covers a wide range of design, development, and marketing activities that require special skills and knowledge.

When Was Pneumonia Vaccine Invented?

Pneumonia is a life-threatening illness that mainly affects the elderly, young children, and people with weakened immune systems. Vaccination is one of the best ways to prevent pneumonia, and it has been available for decades. But when was the pneumonia vaccine invented?

The first pneumonia vaccine was developed in the early 20th century by Dr. Thomas M. Rivers, an American virologist and immunologist. He discovered that by injecting a small dose of killed pneumococcal bacteria into the body, the immune system could produce antibodies to fight off future infections. Dr. Rivers’ work laid the foundation for the development of modern vaccines that are used today.

Over the years, there have been significant advancements in the development of pneumonia vaccines. Today, there are two types of pneumonia vaccines available: the pneumococcal conjugate vaccine (PCV13) and the pneumococcal polysaccharide vaccine (PPSV23).

How Does the Pneumonia Vaccine Work?

The Mechanism of the Vaccine

The pneumonia vaccine works by exposing the body to small amounts of inactive Streptococcus pneumoniae bacteria. This exposure triggers the immune system to create antibodies that can quickly recognize and attack any active Streptococcus pneumoniae bacteria that enter the body in the future.

The PCV13 vaccine uses a protein that is attached to the surface of the pneumococcal bacteria, while the PPSV23 vaccine contains small pieces of the sugar-like coating that surrounds the bacteria. Both vaccines work in a similar way to stimulate the immune system.

The Importance of Vaccination

Vaccination is one of the most effective ways to prevent the spread of infectious diseases like pneumonia. It not only protects the individual who receives the vaccine but also helps to protect those who cannot receive the vaccine, such as infants and individuals with weakened immune systems.

According to the Centers for Disease Control and Prevention (CDC), pneumococcal disease is responsible for more than 900,000 illnesses and 5,000 deaths each year in the United States alone. Vaccination is crucial in the fight against pneumonia and its potentially deadly complications.

Side Effects of the Vaccine

While the pneumonia vaccine is generally safe, some people may experience mild side effects such as soreness at the injection site, fever, or fatigue. Serious side effects are rare. It is always best to consult with a doctor before receiving any vaccine.

In conclusion, the pneumonia vaccine has been available for over a century, starting with Dr. Thomas M. Rivers’ work in the early 1900s. Today, there are two types of pneumonia vaccines available that work by stimulating the immune system to produce antibodies that can fight off future infections. Vaccination is essential for preventing the spread of pneumonia and protecting vulnerable populations.

When was Pneumonia Vaccine Invented?

The development of a vaccine for the prevention of pneumonia dates back to the late 19th century when Sir William Watson Cheyne, a Scottish surgeon, attempted to develop a vaccine to prevent pneumonia caused by Streptococcus pneumoniae, a bacteria known to cause numerous diseases. However, the first vaccine used widespread was not developed until much later.

Dr. John Franklin Enders and his colleagues at Children’s Hospital Boston developed the first successful pneumonia vaccine in 1945. The vaccine was used to prevent pneumonia caused by the pneumococcus bacterium, which is known to be one of the most significant causes of pneumonia worldwide. This vaccine was the first of its kind and provided a way to prevent bacterial pneumonia, a disease that was fatal to a significant number of people until then.

The first pneumococcal vaccine contained up to 14 different types of pneumococcus bacterium, which were prevalent in patients with pneumonia. This vaccine was highly effective and provided protection against up to 85% of the cases of pneumococcal pneumonia.

Who Should Get the Pneumonia Vaccine?

The pneumonia vaccine is recommended for individuals of all ages who are at risk of developing pneumonia. The following are the groups of individuals who should get the pneumonia vaccine:


Children are at a higher risk of developing pneumonia due to their underdeveloped immune systems. The Centers for Disease Control and Prevention (CDC) recommends that children receive the pneumonia vaccine beginning at 2 months old. The initial vaccination should be followed by a booster shot during the second year of life.

Children aged between 6 months and 5 years should get the vaccine as they are more susceptible to pneumococcal infections that can cause serious illnesses such as meningitis, sepsis, and pneumonia.


Adults who are at higher risk of developing pneumonia should also receive the vaccine. The following groups are recommended to get the pneumonia vaccine:

  • Individuals over the age of 65
  • Individuals with weakened immune systems
  • Individuals with chronic respiratory conditions
  • Individuals with certain other health conditions, including heart disease, diabetes, or kidney disease.

Frequency of Vaccination

The type of vaccine received determines the frequency of vaccination. The PCV13 vaccine is typically given once, followed by a dose of the PPSV23 vaccine several years later. Individuals who have never received the vaccine and are at high risk should get vaccinated with both the PCV13 and PPSV23 vaccines.

If an individual has received the PPSV23 vaccine before the age of 65, they should receive an additional dose of the vaccine after they turn 65. It is essential to consult a doctor to determine the best vaccination schedule for each individual based on their risk factors and medical history.

The pneumonia vaccine remains an essential tool for the prevention of pneumonia globally. The availability of the vaccine has helped reduce the incidence of bacterial pneumonia considerably, leading to a decline in the number of pneumonia-related hospitalizations and deaths. Pneumonia vaccines are proven to be safe and effective, and individuals who are eligible to receive them, including children and adults, should get vaccinated.

The Future of Pneumonia Vaccines

New Developments and Research

The pneumonia vaccine has been a critical tool in the fight against infectious diseases. However, researchers are not content with the current state of prevention and are continuing to explore new ways to improve vaccines. One area of study is developing new vaccines that can protect against more strains of the Streptococcus pneumoniae bacteria.

The current vaccine protects against only 23 strains of the bacteria, which is a relatively small number compared to the overall number of strains that exist. Developing vaccines that can protect against more strains is critical, as the bacteria that cause pneumonia can mutate and develop new strains over time.

Another promising avenue of research is using mRNA vaccine technology to speed up and improve the vaccination process. This new technology works by using a small piece of genetic material to train the human immune system to identify and fight specific diseases. Researchers hope that mRNA vaccines for pneumonia will be more effective and faster to produce than current vaccines.

The Need for Continued Prevention

While the development of vaccines has helped to significantly reduce the number of pneumonia cases, the disease still remains a significant public health concern. Pneumonia is particularly dangerous for people with weakened immune systems, including infants, the elderly, and people with certain medical conditions.

Pneumonia can also be caused by a variety of pathogens, not just the Streptococcus pneumoniae bacteria, which makes it difficult to develop a universal vaccine. The best way to prevent pneumonia is to take measures to avoid exposure to the pathogens that cause it. This can include maintaining good hygiene, washing hands frequently, and avoiding close contact with people who are sick.

The pneumonia vaccine is a critical tool in preventing the spread of infectious diseases, but it is only one part of a comprehensive prevention strategy. Continued prevention efforts through vaccination and other measures are necessary to protect individuals and communities from the spread of pneumonia and other serious infections.


The invention of the pneumonia vaccine has helped to save countless lives and prevent the spread of infectious diseases. Thanks to the development of this vaccine, the number of pneumococcal disease cases has decreased dramatically. However, continued research is necessary to improve the effectiveness and accessibility of the vaccine.

It is important for individuals to understand the history, mechanism, and importance of the pneumonia vaccine in order to make informed decisions about their health and the health of their communities. While vaccines are not perfect, they are a critical tool in the prevention of infectious diseases. By continuing to develop and improve vaccines, we can protect ourselves and future generations from the spread of dangerous pathogens.
