What Do We Want To Know?

What are the acute and long-term outcomes of the COVID-19 infection and vaccinations in children?


How Are We Doing It?

Families will be asked if they would like to join the study while in the hospital. During the study, information will be collected from participating children’s medical charts, such as vaccination records, test results, and hospital records. Families will fill out questionnaires about health, quality of life, family daily life, and mental health 4-5 times over one year.

When Will I Be Needed?

This study timeline shows the 5 different study timepoint and time required to complete.

How Is The Study Going?

Our study is currently in progress with recruitment ending in June 2024 – once complete families will have up until March 2025 to finish their follow-ups. Once data is analyzed in 2026, we will share a summary of the results with POPCORN participants!

 Who Can Participate?

About 6,400 children and their families will take part in this study across Canada. POPCORN will invite children less than 18 years of age who came to the hospital recently and are being tested either for a COVID-19 infection or a rare complication sometimes associated with COVID-19 infection or a rare complication, such as MIS-C.


Biosample Sub-Study

In this study, blood samples will be collected from patients with confirmed MIS-C, myocarditis, and pericarditis following COVID-19 vaccination or infection, as well as from controls. These samples will be used in national and international research into the causes and risk factors of adverse events following vaccination and MIS-C.

When Will My Blood Be Taken?
