How serious is pneumococcal infection?
The range is wide. The Centre for Health Protection puts it this way: pneumococcus generally causes only milder illness such as sinusitis and middle ear infection, but it can also cause severe and even fatal invasive pneumococcal disease — bacteraemic pneumonia, septicaemia and meningitis.
“Invasive” means the bacterium reaches a site that should be sterile, such as the blood or cerebrospinal fluid. The same organism can cause a middle ear infection or meningitis; the difference lies not in the bacterium but in where it reaches and in the host’s resistance — which is why the vaccination programme is organised by age and risk.
Who is eligible for free or subsidised vaccination?
The Centre for Health Protection states that the Government’s pneumococcal vaccination programme runs year-round, providing free or subsidised vaccination to eligible people aged 65 or above.
Bring a Hong Kong identity card or a certificate of exemption, along with any existing vaccination record. Unlike the influenza vaccine this is not an annual injection, so what was given before directly determines what should be given now.
