Which vaccine is indicated for pneumococcal disease prevention?

The prevention of pneumococcal disease is specifically targeted by the PPSV23 vaccine. This vaccination is important because pneumococcal diseases are caused by the bacterium Streptococcus pneumoniae, which can lead to serious infections such as pneumonia, meningitis, and bacteremia. PPSV23 (Pneumococcal Polysaccharide Vaccine), also known as Pneumovax 23, is designed to protect against 23 types of pneumococcal bacteria, making it effective in reducing the incidence of pneumococcal infections, especially in high-risk populations such as the elderly, individuals with compromised immune systems, and those with certain chronic illnesses.

The other vaccines listed serve different purposes: the MMR vaccine protects against measles, mumps, and rubella; the varicella vaccine is for chickenpox; and the HPV vaccine is intended to prevent human papillomavirus infections and related cancers. Therefore, PPSV23 is clearly the vaccine indicated specifically for the prevention of pneumococcal disease.
