Infections Prevented by Routine Immunization and Immunization Coverage

Key Findings: 
  • Between 2000 and 2010 there were no diphtheria, measles, polio, or rubella infections reported in Middlesex-London (Fig. 8.35).
  • During the same time period, the annual average incidence rate of influenza, measles, mumps, pertussis, rubella and invasive Streptococcus pneumoniae infections were lower for Middlesex-London compared to the rates for Ontario (Fig. 8.35). Invasive meningococcal disease was the only infection for which the annual average rate for Middlesex-London (1.0/100,000) was greater than the rate for the province as a whole (0.5/100,000) (Fig. 8.35).
  • Between 2000 and 2010, the most common diseases potentially prevented by immunization reported in Middlesex-London was influenza, followed by invasive Streptococcus pneumoniae and pertussis infections (Fig. 8.36).
  • During the 2010/11 school year, the percent of 7-year old children in Middlesex-London who were immunized against diphtheria, measles, mumps, polio, rubella and tetanus ranged from a high of 97.9% for mumps and rubella to 92.9% for polio (Fig. 8.37).
  • Since 2007/08, the percent of Middlesex-London long-term care home (LTCH) residents who received seasonal influenza immunization was lower compared to the provincial median (Fig. 8.38).
  • Between 2004/05 and 2010/11, the percent of LTCH residents who received seasonal influenza immunization declined in both Middlesex-London and Ontario as a whole (Fig. 8.38).
  • The percent of LTCH and hospital staff in Middlesex-London who received seasonal influenza immunization declined between 2004/05 and 2010/11. However, the percent of LTCH staff immunized consistently exceeded that among hospital staff (Fig. 8.39).

Between 2000 and 2010, a total of 18 adverse events following immunization (AEFI) were reported in Middlesex-London; the majority (83.3%) of these reports were among females (Fig. 8.40).
