COVID-19 Research

The CANVAS COVID-19 Vaccine Safety Study

Julie Bettinger and Manish Sadarangani

Vaccine clinicThe Canadian National Vaccine Safety (CANVAS) Network is a national research platform that monitors vaccine safety after vaccines are approved for use. We are monitoring the safety of the COVID-19 vaccines in Canada and we need YOUR help.

Using web-based surveys, we will collect information about whether or not health events occur after receiving COVID-19 vaccines. We will also collect health events from people who have not received a COVID-19 vaccine.

If you want to participate in this research study, please go to to register in the group that applies to you (whether you have received a COVID-19 vaccine or you have not). If you haven’t received the vaccine, you can still participate in the non-vaccinated (control) survey. If you join the non-vaccinated group, you may later re-join the vaccinated group once you’ve received the vaccine.

COVID-19 Immunity Study

Manish Sadarangani

COVID 19 immunityAs the public health emergency of COVID-19 continues to spread and evolve quickly within our province, rapid development of SARS-CoV-2 blood tests is of critical importance — particularly as it pertains to the ability of our laboratories to analyze SARS-CoV-2 blood test results and understand how the immune system responds to the pathogen.

The development of these tests will help to identify and track subsequent waves of the virus, and help doctors and researchers understand the disease further, which could help in the development of future treatments and/or vaccines.

COVID-19 Online Discourses

Julie Bettinger

Coronavirus misinformationAs public health authorities increase efforts to address the new coronavirus epidemic, rumours, misinformation, and xenophobic online posts are spreading faster than the virus. Fear and misinformation have direct impacts on the implementation of effective public health measures to control the epidemic. VEC researchers will examine the individual and sociocultural factors that impact individuals' and communities' adoption of public health recommendations; describe how public health measures are portrayed in the media and how individual/community understanding of disease, priorities, fears, and public health messaging impact the acceptance of measures to limit the spread of COVID-19. We will also identify interventions that will help build public trust in authorities responsible for disease spread and management, while dispelling unfounded rumours and xenophobic discourse.

COVID-19 Community Response Study

Two South Asian women sitting under treesThe spread of COVID-19 has had a lasting impact on our population. However, the challenges presented by the pandemic and related public health measures have disproportionately affected some communities. Furthermore, certain communities have expressed concerns with the COVID-19 vaccine resulting in increased hesitancy. This study aims to identify the information needs, values, beliefs, and experiences with the COVID-19 pandemic and related public health measures among the South Asian community in the Lower Mainland. Researchers are also interested in understanding this community’s experiences, perspectives, and information needs surrounding the COVID-19 vaccination. The goal of the study is to inform pandemic and vaccine related programs.

a mother and babyInfluenza (flu) is a highly contagious respiratory infection caused by an influenza virus. Children are especially vulnerable and at greater risk of flu complications. Researchers would like to compare 2 licensed flu vaccines to find out which one provides better protection for young children. The study involves 7 visits over 18 months at the VEC located at the BC Children's Hospital Research Institute in Vancouver. Visits will include blood tests, 3 flu shots (over 2 seasons), and questions about your child's health.

Meningococcal Research

Meningococcal Vaccine Study

meningitis vaccines CanadaMeningococcal disease is caused by Neisseria meningitidis and can result in severe disease such as septicemia (blood poisoning) and meningitis. There are currently 3 different vaccines being offered to teenagers across Canada and researchers at the Vaccine Evaluation Center would like to find out if there are any differences between these 3 vaccines, and if any of them are better than the others.

HPV Research

teens HPV vaccine uptake in CanadaDespite the fact that school-based HPV vaccination programs are known to be an effective strategy to reach target populations, uptake is suboptimal. VEC researchers are looking to understand the factors that influence vaccination uptake such as attitudes, values and beliefs about HPV vaccination by decision-makers, health professionals, teachers and parents and organizational factors relating to the way the HPV programs are delivered.

Pneumococcal Research

Pneumococcal Vaccine Study

Manish Sadarangani

pneumococcal vaccine study CanadaPneumococcal disease is caused by the bacteria Streptococcus pneumoniae. Although the vaccine is given as 3 shots at 2, 4, and 12 months of age, VEC researchers would like to find out if it is possible to achieve the same protection using just 2 shots at 2 and 12 months.


Pneumococcal Vaccination in High Risk Children

Manish Sadarangani

immunocompromised kids vaccines vaccinationSome medical conditions may compromise a person's immune system and therefore can make that person more at risk than usual for developing Pneumococcal disease. These people might need additional doses of the vaccine to help protect them. Researchers at the VEC are doing this study to help doctors make sure that these additional vaccine doses are helping to protect the children or young adults who are at a greater risk for Pneumococcal disease.

Vaccine Hesitancy Research

Unpacking Vaccine Hesitancy Among Perinatal Healthcare Providers

Julie Bettinger

vaccine hesitancy among healthcare providers health careHealthcare providers (HCPs) are known to play a crucial role in fostering vaccine acceptance among parents. Previous research indicates that pregnant women want more and clearer vaccine advice from the doctors, nurses, and midwives providing care from pregnancy through the immediate postpartum period, when many mothers struggle with prenatal vaccination questions and begin making their infant vaccination decisions. When HCPs communicate effectively about the value and need for vaccinations parents are more confident in their decisions. However, research indicates that HCPs need more training and information support in order to feel confident recommending and administering vaccines. VEC researchers are working to gain an in-depth understanding of the vaccine hesitancy of perinatal HCPs, including how attitudes and beliefs are evident in both training and clinical practice.

Addressing Vaccine Hesitancy in an Indigenous Community

Currently recruiting studies in canada vaccine researchParticipants needed: Must be referred by public health or your doctor.

Why are we doing this study: This study will collect information about adverse reactions following immunization from patients attending the Special Immunization Clinic. The information collected will help build standard care plans that guide doctors as they care for patients with adverse reactions.


A Prospective Analysis of Mandated Documentation

Julie Bettinger

vaccination coverage in British ColumbiaA structural intervention to increase vaccination among schoolchildren in British Columbia: Motivated by concerns of inadequate vaccination coverage and the potential for vaccine-preventable disease outbreaks, Canadian provinces have been discussing, implementing, and tightening policies requiring documentation of vaccination for school enrollment. In 2019, British Columbia introduced a regulatory mechanism under the provincial Public Health Act mandating documentation of immunization for school enrollment. Therefore, VEC researchers are evaluating the intervention as the province takes steps to implement policies of mandatory documentation of immunization for school enrollment, taking advantage of this policy change to observe outcomes, and explore factors related to implementation success.
