The 0.5 mL dose contains purified capsular polysaccharides from these 23 serotypes, providing immunity to individuals at risk, including the elderly, those with chronic conditions, and individuals with weakened immune systems. The vaccine is typically administered as an intramuscular or subcutaneous injection and is recommended for people aged 2 years and older. It helps reduce the risk of severe pneumococcal infections and is a key part of preventive healthcare for vulnerable populations. Like all vaccines, it is important to follow the recommended guidelines and consult a healthcare provider regarding any potential side effects or contraindications.
