Immunization stress-related responses: Improving our understanding of a type of adverse event following vaccination

C. Meghan McMurtry - PhD, C.Psych, Associate Professor of Psychology, University of Guelph.

G. is a 15-year-old girl waiting in line to get her immunization at school. She starts to feel a bit dizzy and her heart starts to pound. G. becomes worried about what the needle is going to feel like. By the time she reaches the nurse, all she wants to do is get out of there. She faints immediately after the needle is removed.

Vaccine Acceptance in Canada: Building confidence, demand and resiliency

The CANVax Team

Vaccine acceptance has become a growing concern as we see outbreaks of diseases once thought to be under control and on their way to eradication. Despite the tremendous strides made in vaccine development, safety, and access, some parents continue to question the need for vaccines, their safety and effectiveness, and are hesitating to accept vaccines. Vaccine hesitancy is defined as the reluctance or refusal to vaccinate despite the availability of vaccines and is both complex and context specific, varying across time, place and vaccines. It is influenced by factors such as complacency, constraints (convenience) and confidence.

Immunizing kids is important. Helping them overcome pain and fear of immunization is important too.

Lucie Marisa Bucci - Senior Manager (Immunize Canada)

Immunizing school children is an effective way to increase coverage. Most public health jurisdictions in Canada have school immunization programs, which roll out meningococcal, hepatitis B and HPV vaccines, among others. The positive outcomes of these programs are numerous. Yet, we are just beginning to learn that a substantial number of children who receive vaccines at school have negative experiences. Often these negative experiences are attributed to pain and fear of needles. For some children, injection needles conjure anxiety and distress that can perpetuate into episodes of fainting, and eventually to vaccine refusals.

Fake News and Science Denier Attacks on Vaccines. What can healthcare professionals do?

Noni MacDonald - Professor of Paediatrics (Infectious Diseases)

Never before has the public been so bombarded by information, nor has it ever been so difficult to know what and who to believe. Misinformation is contagious; with fake news travelling faster and farther than truth. Science deniers, including vaccine science deniers, have a strong and very effective platform now - the web - from which to shill their scientifically bankrupt wares. We, who understand the rigor of science and know the evidence supporting immunization for health and well-being, are often aghast at the falsehoods being promulgated - and indeed- too often accepted and acted upon by members of the public. For example, in the US, the variation HPV vaccine uptake across the country is better explained by exposure to tweets about HPV than by socioeconomic class data.

Optimizing communication tools to address vaccine hesitancy

Ève Dubé - Medical Anthropologist, Researcher

Vaccine hesitancy (the reluctance to accept recommended vaccines) is a complex issue that poses risk communication problems for public health agencies. Studies have shown that providing information and communicating evidence of vaccine safety and efficacy to those who are vaccine-hesitant has done little to stem the growth of hesitancy-related beliefs and fears. In this CANVax in Brief, we highlight good practices informed by research evidences in developing communication materials to address vaccine hesitancy.

Welcome to CANVax in Brief

The CANVax Team

The Canadian Vaccination Evidence Resource and Exchange Centre (CANVax) is an online database of resources to support immunization program planning and promotional activities to improve vaccine acceptance and uptake in Canada. CANVax aims to make it easier for public health professionals to find and collect resources by increasing access to information relevant to the Canadian context. CANVax is the first online database of its kind in Canada to equip public health professionals with access to a centralized resource centre focused on vaccine acceptance and uptake.
