COVID-19: Potential Impact on Vaccine-Preventable Diseases in Canada

Noni MacDonald, Eve Dubé, Lucie Marisa Bucci

The rapid spread of SARS-CoV-2 has led to an unprecedented number of COVID-19 cases and deaths globally, as well as in Canada.

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.
