Pneumococcal Vaccine

The pneumococcal vaccine is a type of vaccine that protects against infections caused by the bacterium Streptococcus pneumoniae, also known as pneumococcus.

Types of Pneumococcal Vaccines

• PCV (Pneumococcal Conjugate Vaccine): This vaccine protects against 13 types of pneumococcal bacteria and is recommended for children under the age of 2, as well as adults over 65.
• PPSV (Pneumococcal Polysaccharide Vaccine): This vaccine protects against 23 types of pneumococcal bacteria and is recommended for adults over 65, as well as younger adults with certain health conditions.

How the Vaccine Works

The pneumococcal vaccine works by introducing a small, harmless piece of the pneumococcal bacterium to the body, which triggers an immune response and helps the body develop immunity to the infection.

Benefits of the Vaccine

• Prevents Pneumococcal Disease: The vaccine can help prevent pneumococcal disease, including pneumonia, meningitis, and sepsis.
• Reduces Risk of Complications: The vaccine can also reduce the risk of complications from pneumococcal disease, such as brain damage, hearing loss, and death.

Who Should Get the Vaccine

• Children under 2 years old: PCV is recommended for all children under 2 years old.
• Adults over 65 years old: PPSV is recommended for all adults over 65 years old, as well as PCV for those who have not previously received it.
• Younger Adults with Certain Health Conditions: PPSV is also recommended for younger adults with certain health conditions, such as heart disease, lung disease, or diabetes.

Possible Side Effects

• Mild Side Effects: Mild side effects of the pneumococcal vaccine may include redness, swelling, and pain at the injection site, as well as fever and fatigue.
• Severe Side Effects: Severe side effects are rare but may include allergic reactions, such as hives, itching, and difficulty breathing.

Contraindications and Precautions

• Severe Allergic Reaction: The vaccine should not be given to anyone who has had a severe allergic reaction to a previous dose of the vaccine or to any component of the vaccine.
• Weakened Immune System: The vaccine may not be effective in people with weakened immune systems, such as those with HIV/AIDS or taking immunosuppressive therapy.
