At the beginning of the pandemic, COVID-19 was generally very mild in young children, creating a sense that most were not at risk.

Once Omicron struck, the millions of people infected led to increased numbers of serious cases, including in children. This included some rare yet serious and lingering complications. Furthermore, the rigorous process before vaccines were approved for children caused delays in pediatric vaccination. Coupled with poorer vaccine uptake in young children, this has led to gaps in immune protection against COVID-19.

The CITF has funded several studies examining the impact of SARS-CoV‑2 on pediatric populations, as well as vaccine efficacy and the durability of immune responses in children. Join our CITF-funded experts for an informative discussion about the current state of research on COVID-19 and pediatrics in Canada.
