Aim: To investigate the seroprevalence of these infections in adolescents who attended to pediatric outpatient clinics. Material and Method: Age, gender, and socio-economic status of 255 adolescents who participated in the study were recorded. Vaccination data against measles, rubella, mumps, and varicella was obtained from the immunization cards and “doctor diagnosis” of those viral infections was reported by the parents. Serum specific IgG levels for measles, rubella, mumps, and varicella were measured in all cases. Results: The mean age of the cases were 11.8±1.8 years with a female rate of 59.2 %. The rates of having measles, rubella, mumps, and varicella history were 45.1 %, 3.9 %, 43.5 %, and 55.7 % and the rates of vaccination against those viral infections were 96.9 %, 2.0 %, 0.4 %, and 1.2%, respectively. Seropositivity rates were 81.6 %, 85.5 %, 80.0 %, and 71.0 %, respectively with the same order. When analyzed, it was observed that there were positive correlations between history of having measles and varicella infections and specific seropositivity r= 0.12, p=0.04 ve r= 0.21, p= 0.001 respectively . 96.9 % of measles seropositive cases had a history of vaccination, whereas 46.6 % had both vaccination and infection. There was no vaccine history in any of varicella seropositive adolescents with a positive disease history in 80.3 %. Conclusion: As varicella can cause serious complications in adults, immunization of seronegative adolescents with varicella vaccine which is not included in the current national vaccination schedule may be useful
