Article Synopsis
- New vaccine products for invasive pneumococcal disease (IPD) were authorized in Canada, prompting a study to examine trends in IPD incidence and severity in Ontario across different time periods, including pre- and post-vaccine introduction and during the COVID-19 pandemic.
- The analysis revealed a decline in IPD incidence and hospitalizations among children under 5 years after the introduction of the 13-valent vaccine (PCV13), but an increase in case fatality rates and hospitalizations among older adults.
- Despite the overall decrease in cases from PCV13 serotypes, there was a rise in cases from newer serotypes, highlighting the need for ongoing surveillance and possible adjustments to vaccination strategies.
