Infants and young children are more vulnerable to vaccine-preventable diseases because their immune systems are less mature1 and may have a higher risk of complications from some vaccine-preventable diseases.2
Did you know: In 2016, approximately 18.7 million infants worldwide were still missing their routine vaccinations3 and in 2019, nearly 10 percent of Canada’s childhood population were not vaccinated against diphtheria, tetanus and pertussis.4
