Sweden Adds Chickenpox Vaccine to National Childhood Program

Sweden will integrate chickenpox vaccinations into its national childhood program in 2027, according to government announcements. The initiative provides two vaccine doses at 18 months and between 7 and 8 years of age. A separate catch-up campaign for children aged 5 to 17 will begin March 1, 2027, to ensure broader immunity across older age groups.

How will the national chickenpox vaccination be administered?

The vaccine will be offered to all children in two separate doses, according to the national program. These doses are scheduled for 18 months and again at 7–8 years of age.

The government and Sveriges Kommuner och Regioner (SKR) have established a three-year agreement covering 2027–2029 to support this rollout. This agreement aims to provide municipalities and regions with the long-term conditions necessary to reach the target group, according to Anna-Lena Hogerud, chair of SKR’s healthcare delegation.

Did You Know? The introduction of the national program is expected to result in the disease ceasing to circulate within society within seven years.

Why is a catch-up vaccination campaign necessary?

Children older than 18 months when the program begins are not automatically covered, which could leave them without protection. As the disease circulates less in society, these unvaccinated children may be infected at an older age.

According to official reports, infection at an older age carries an increased risk of severe illness and a higher likelihood of requiring hospital care. To prevent this, the government is financing a temporary “catch-up” effort for children aged 5 to 17 who are not yet immune.

Expert Insight: Samantha Carter notes that the catch-up campaign addresses a critical epidemiological gap. By targeting the 5–17 age bracket, health officials aim to prevent a shift in the disease’s age profile, which could otherwise lead to more complex clinical cases in adolescents.

What are the expected health and social outcomes?

Social Minister Jakob Forssmed stated that the goal is to eradicate chickenpox in Sweden to spare children a painful illness and reduce the amount of time parents spend on leave to care for sick children.

Beyond individual cases, high vaccination coverage is intended to prevent severe illness and help counteract antibiotic resistance, according to Forssmed.

What may happen next?

While the current agreement with SKR runs through 2029, the catch-up effort is expected to last longer than three years. A supplementary agreement for the period following 2029 is likely to be signed to maintain the program’s momentum.
