Estonia has witnessed a concerning rise in tick-borne encephalitis (TBE) cases, with 143 individuals reported infected in 2025, highlighting the importance of vaccination amidst increasing tick activity due to warmer winters. Public interest in vaccinations has been at an all-time high, aiding in controlling the spread of the disease. The Estonian Health Board has noted that while the past winter was slightly colder, the arrival of warmer weather indicates it is crucial for residents to protect themselves by getting vaccinated.

The trend of rising TBE cases has been evident, with 209 cases recorded in 2023 compared to only 82 in 2021. This surge in cases emphasizes the need for proactive health measures. Vaccination has proven effective in curbing disease transmission, prompting authorities to modify the vaccination schedule, extending the booster interval for those under 50 from five years to ten starting in 2026.

The early spring climate, where temperatures consistently rise above 5-7 degrees Celsius, signals the increased activity of ticks, which can lead to more TBE infections. Health officials are urging the public to get vaccinated in a timely manner to ensure adequate protection against the disease, especially with the projected warmer months ahead, emphasizing the need for continuous awareness and vaccination efforts.
