Background

The number of parents refusing to vaccinate their children has been increasing year by year.

Objectives

The aim of the study was to analyze child vaccination at the Outpatient Clinic of the Pro Medica Center in Bialystok, Poland, in the years 2013–2016.

Material and methods

A total of 10,150 histories of children and adolescents were analyzed. We analyzed the following data: number of children and adolescents vaccinated in 2013–2016; type of vaccination; reimbursed and polyvalent vaccines; vaccinations against tuberculosis; occurrence of contraindications to vaccination; number contraindications to vaccination, and number of vaccinations recommended in the particular years.

Results

48.8% of the children were vaccinated with refunded vaccines. 18.3% of children were not vaccinated in 2016. 60.3% were BC G-vaccinated. There was an increased number of contraindications for vaccination from 2013 to 2016, mainly in children aged 2, 6, 7, and 10 years. In 2016, the number of vaccinations against rotaviruses decreased, and the number of vaccinations increased against meningococcus and tick-borne inflammation. There was a statistically significant decrease in vaccination against diphtheria and tetanus from Haemophilus influenzae B, pertussis, poliomyelitis; and measles, mumps, and rubella, from 2013 to 2016.

Conclusions

In the years 2013–2016, there was an increase in the incidence of contraindications for protective vaccinations, a decrease in the number of vaccinations against rotaviruses, and an increase in the number of vaccinations against meningococcal meningitis and tick-borne encephalitis.
