Vaccination coverage for vaccine‐preventable diseases in Austria as well as in many Central European countries has been reported to be too low to eradicate such diseases and prevent further outbreaks. Austria lacks an adequate surveillance system to monitor prevalence of the diseases, the vaccination coverage and seroconversion. School children aged 10–14 years (n = 1077) were recruited in all four schools in the city of Schwaz, Austria, to present their vaccination documents and to give blood for serological testing (diphtheria, pertussis, measles, mumps, rubella, varicella). All participants received a report with a personal guideline for (re‐) vaccination. Overall vaccination coverage was 86.4% for measles, 85.5% for mumps and 35.0% for rubella. Tetanus vaccination coverage was 98.4% for the first, 97.8% for the second and 96.7% for the third dose, while 55.4% of the study subjects received the recommended two booster injections. For diphtheria the corresponding vaccination coverage was found to be almost identical. Pertussis coverage was lower in general (first dose: 90.9%; second dose: 89.0%; third dose: 86.5%). Oral poliomyelitis vaccination showed a coverage of 98.6, 96.5, 95.3%, with 78.7% receiving the fourth dose. Overall 38.7% were classified as fully vaccinated. Seropositivity for measles was found in 90.4%, for mumps in 61.8%, for rubella in 82.3%, for diphtheria in 65.8%, for pertussis in 35.6% and for varicella in 95.0%. In summary, fully vaccinated children are rare and intensive public health efforts will be necessary to reach higher levels of immunity and prevent further outbreaks.
