When is a tick vaccine given to children? - briefly
The vaccine is recommended for children aged 5 to 10 years, administered as a two‑dose series (first dose, followed by a booster one month later) before the onset of the tick‑active season. It is given only when the child is at risk of exposure to tick‑borne diseases in endemic areas.
When is a tick vaccine given to children? - in detail
The tick‑borne disease vaccine is administered to children based on age, exposure risk, and regional disease prevalence.
For the tick‑borne encephalitis (TBE) vaccine, which is the only licensed product for pediatric use in many European and Asian countries, the schedule is:
- First dose: given at 12 months of age (or as early as 6 months for certain formulations).
- Second dose: administered 1–3 months after the initial injection.
- Third dose (booster): given 5–12 years after the second dose, depending on the product’s recommended interval.
If a child will travel to a high‑risk area during the tick season, the primary series should be completed at least two weeks before departure to allow sufficient antibody development.
For the Lyme disease vaccine under development, clinical trials target children aged 5 years and older; the proposed regimen mirrors adult protocols: two primary doses spaced one month apart, followed by a booster at 12 months. Approval and exact timing remain pending.
Key factors influencing the decision to vaccinate:
- Residence in or travel to regions where TBE or Lyme disease are endemic.
- Seasonal exposure, typically from late spring to early autumn.
- Age eligibility defined by the specific vaccine’s licensing information.
Healthcare providers assess these variables to determine the optimal moment to initiate the vaccine series and schedule subsequent doses.
