Community-based COVID vaccination center ready for the switch towards a broad community-based prevention center: In Jan'21 the Flemish Region started the COVID vaccination in a public health mode, at 60 primary health care units

Framework: Each local “unit of care” has an average population of 100.000 people and is managed by local caregivers. Within two months (Jan-Feb'21), 80 vaccination centers were set up and launched. A central strategic center and logistic/financial support were created. A local team of municipal representatives and caregivers was composed. It resulted in a management team which launched the operational vaccination sessions. All citizens were invited by email, letter or SMS. An individual appointment was booked in the vaccination center matching the zip code of the citizen’s residence. Specific software enabled vaccination agenda management and its registration in Flanders’ central vaccination database. The initial goal was to cover at least 70% of the target population, but in the primary care unit “Voorkempen”, a coverage of 95,45% was reached. Vaccination center “Voorkempen” ‘s results: The health unit “Voorkempen” is a defined area, situated in the province of Antwerp and is composed of 6 municipalities which give home to 111.102 inhabitants. The campaign consisted of four periods : - Feb-Sep'21 : basic vaccination (97.763 citizens) - Oct'21-Feb'22 : 1st booster campaign for all 12+ ( 93.316 citizens). - May-June'22: extra booster exclusively for 80+ (7.153 citizens) - Sept-Oct'22 : 2nd booster for all 18+, (90.473 citizens) Lessons learned: 1.Flexible management by a limited number of managers (4) with daily meetings and quick decision making is essential and covers : A.The infrastructure in time and space.
