Immunization Coverage Reports

BCCDC works with the province’s regional health authorities to assess immunization coverage.

Immunization coverage is the percentage of people who receive one or more vaccines in relation to the overall population.
For example, immunization coverage for influenza among people aged 65 years and over is the number of people aged 65 years and over who received an influenza vaccine the previous season compared to the total population aged 65 years and over. 

Monitoring trends in coverage is important in order to identify the potential for outbreaks of vaccine-preventable diseases. When coverage rates drop in a population, the chances of a vaccine-preventable disease outbreak occurring in that population increase.  

Coverage is assessed in order to:

  • measure how many people are protected against vaccine-preventable diseases within the overall population
  • identify populations (people living in certain communities) that have low vaccine coverage in order to explore reasons for low coverage
Monitoring also helps BCCDC in recommending where public health should allocate its resources, for example, where to improve access to immunization services or public education efforts.  

In BC, immunization coverage is routinely measured for:
  • children at the second birthday
  • school-age children
  • influenza-vaccine recipients

A routine immunization schedule is in place in the BC health care system. Through this schedule, infants and toddlers in BC are offered vaccines that protect against many different diseases.


Most infants and toddlers are immunized either by public health nurses at their local health unit or by their family physicians. Immunization records are kept for most children in in the province’s immunization registry, called Panorama. Panorama records are used to measure immunization coverage for children living in the Fraser, Interior, Vancouver Island and Northern health authorities. Immunization coverage is measured for two-year-olds living in the Vancouver Coastal Health Authority by periodic surveys.

Immunization coverage in children

Generally, the percentage of children who are fully immunized before their second birthday has ranged from 65% to 73%.


Immunization coverage report:

In British Columbia, vaccines are routinely provided to school-age children at school entry (4-6 years of age), Grade 6 and Grade 9. The vaccines provided are listed below for each grade.


School Entry:

  • Tdap-IPV (tetanus, diphtheria, acellular pertussis and polio)
  • MMRV (measles, mumps, rubella and varicella)
  • Hepatitis A (for Aboriginal children only)
Grade Six:
  • Hepatitis B (if not previously immunized)
  • Varicella (if not immune)
  • Human papillomavirus (HPV)
Grade Nine:
  • Men-C-ACYW (meningococcal types A, C, Y and W)
  • Tdap (tetanus, diphtheria and acellular pertussis)
