Pneumococcal disease is caused by bacteria and can result in a range of ailments, from mild ear infections to meningitis, sepsis and fatal pneumonia . Adults over the age of 65, especially those with chronic illnesses, are at an increased risk for pneumococcal disease and death . The incidence rate of invasive pneumococcal disease (IPD) in Israel between 2009-2010 for those aged 65-74 years was 20 per 100,000 people; incidence rate increased as age increased, with a case-fatality rate of 25% among 65-74 years-old, and 35% among those 85 years-old and older . In addition to the childhood immunization routine, the Israeli Ministry of Health recommends that persons aged 65 years or older will receive the PPV23 pneumococcal vaccine, if more than five years have elapsed from the previous PPV23 vaccination .
