Pneumococcal 20-valent conjugate vaccine（PCV20）

Pneumonia is one of the major causes of death in Hong Kong. Pneumococcal infection, particularly infection caused by certain serotypes such as serotype 3, may lead to serious illness and a higher risk of complications.
 
Pneumococcal bacteria can cause a range of conditions, including middle ear infection and pneumonia. In more severe cases, they may lead to invasive pneumococcal disease, such as meningitis when the infection affects the membranes around the brain, or bacteraemia and sepsis when it enters the bloodstream. These conditions can be serious and potentially life-threatening.
 
The PCV20 covers 20 pneumococcal serotypes:
 
1, 3, 4, 5, 6A, 6B, 7F, 8, 9V, 10A, 11A, 12F, 14, 15B, 18C, 19A, 19F, 22F, 23F and 33F
 
With broader serotype coverage, the vaccine helps protect against pneumococcal disease and supports longer-term immune memory. It is given as a single-dose vaccination and may be administered at the same visit as the influenza vaccine or COVID-19 vaccine, subject to medical assessment.
 
The PCV20 has been approved by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA).
