Measles in Canada

Measles in Canada – March 2019 (pdf) – new 16 page report by Nelle Maxey

This report explores the following questions:
Page 1: From the Brady Bunch to the ‘Fraidy Bunch’

Page 2: Is measles a deadly disease?
Mortality Chart data from 1921–2016 from Statistics Canada.
Page 3: How many measles cases are occurring?
Chart of reported case numbers from the Health Canada Notifiable Diseases database from 1924–2016.

  • Explores the number of measles cases reported versus the number of measles cases actually occurring in the population.
  • Examples of case fatality rate calculations for 1935, 1957 and 1970 included.

Page 4: What are the rates per 100,000 population of measles cases?
Charts of reported rates from the Health Canada Notifiable Diseases database.

  • Pre-vaccine era from 1924–1969.
  • 1-dose MMR vaccine era from 1970– 1997
  • 2-dose vaccine era from 1998–2016

Page 5 & 6: Who is getting measles in Canada in the Vaccine Era?
Age Group Charts from the Notifiable Diseases database for Outbreaks from 2002–2016.

  • Explores the shift of measles into older age groups in the vaccine era, the percent of the population with natural measles life-long immunity and the incidence of measles by age group.

Page 6-7: Vaccine Immunity in the 2011 Quebec Outbreak
Explores the Chief Medical Officer of Health in Quebec writing about the shift of measles incidence into the adolescence population, the majority of cases in the vaccinated, underreporting of attenuated measles cases in the vaccinated and the effect on Canada’s elimination of measles status.
Page 8-9: What Does Measles Elimination Really Mean?
Explores World Health Organization (WHO) definitions and criteria for eradication including discussion of Canada’s surveillance system and R Factor estimates, and threats to Canada’s elimination status.
Page 9: Epidemiologist predicts measles will become a disease of the vaccinated
Effects of lack of measles vaccine efficacy due to primary and secondary vaccine failure explored in Dr. Gregory Poland’s epidemiology papers. Evidence in the current 2019 British Columbia measles outbreak of Poland’s predictions.
Page 10-11: Why ‘Vaccine Herd Immunity Theory’ doesn’t work in the real world
Explores the work of various researchers on the falling levels of antibodies to measles virus (blood titers) in vaccinated persons, and the resulting measles infection and transmission in vaccinated persons. Includes Dr. Tetyana Obukhanych’s summation that 100% vaccination compliance can at best make only 25% of the population immune from measles for 10 years.
Page 11-13: Flies in the Ointment
Explores further effects of measles vaccines lack of efficacy on Immunoglobulin supplies that are used for protection of vulnerable populations (infants, pregnant women and the immunocompromised) and on the number of vaccine strain measles cases and the need to identify these in outbreak situations.
Page 13-15: Why Eradication?
How vaccine development progressed to eradication policies. Explores the difference between public health needs and market opportunity for vaccine producers. Includes ICAN’s documentation of lack of safety testing on childhood vaccines that protects vaccine manufactures not children’s health.
Page 15-16: Vaccine Safety and Adverse Event Reports
Brief discussion of Canada’s two vaccine safety surveillance systems, references to adverse events studies of measles vaccines and summation of Canada Vigilance (CV) database adverse event reports posted from the 1960s to 2018. PDFs of the CV adverse event reports post with this Measles Report.

Reported Cases of Measles in Canada
All charts downloaded from Health Canada Notifiable Diseases On-line Feb 2019
Measles was removed from the Notifiable Diseases list from 1959 to 1968, so no data is available.
The data has not been updated since 2016.

 Letter to Ontario School Boards

In response to the suspension of students in ON schools for not reporting vaccination status, the following letter was sent to Ontario’s 85 School Boards via Canada Post.

 Open Letter to Public Health Agency of Canada

We are writing in response to the information being disseminated by the Public Health Agency of Canada in ‘A Parent’s Guide to Vaccination’. The broader medical community, the public, and especially parents look to health authorities such as the
Public Health Agency of Canada (PHAC) to provide accurate, up-to-date information to assist in making informed decisions regarding the health and safety of children.

 Open Letter to Fraser Health Authority

In response to information sent to school administrators from Fraser Public Health in BC, a joint letter from VCC, Canada Health Alliance, World Council For Health Canada, and Children’s Health Defense Canada was sent to Fraser Health and others.
