Furthermore, healthcare providers played a crucial role in promoting vaccination by discussing the vaccine with parents during routine well-child visits and answering any questions or concerns they may have had. Vaccination clinics were also set up in schools and community centers to make the vaccine easily accessible to eligible individuals.

Target Age Groups

The Canadian National Advisory Committee on Immunization (NACI) recommends routine vaccination against chickenpox for children and certain high-risk individuals. The routine schedule suggests that children receive two doses of the vaccine:

• The first dose at 12 to 15 months of age
• The second dose at 4 to 6 years of age

The NACI also recommends the vaccine for non-immune individuals who are at high risk of severe complications from chickenpox, such as individuals with weakened immune systems or pregnant women who are not immune to the virus.

Recommendations from Health Authorities

Health authorities, including Health Canada and provincial health departments, strongly endorse the use of the chickenpox vaccine to prevent illness and its complications. They emphasize the importance of vaccinating children according to the recommended schedule to ensure long-term protection against the disease.

Healthcare providers are encouraged to educate parents and caregivers about the vaccine’s benefits and address any concerns they may have. Ongoing monitoring and surveillance are also conducted to assess the vaccine’s effectiveness and safety.
