We found susceptibility for measles in 11.7% individuals (95% confidence interval (95% CI): 8.0-15%), for rubella: 6.7% (95% CI: 3.8-9.6%) for mumps: 12.7% (95% CI: 8.0-16.6%) and for varicella 8.5% (95% CI: 5.3-11.7%). Compared to a similar study, performed in 1992 in a population of health care workers, we found an increasing sus...
