DTP: Diphtheria-tetanus-pertussis; MMR: measles-mumps-rubella.

^a For the calculation of the vaccination coverage for MMR that refers to children 1–14 years of age (n = 3,501) the respective denominators were used: 1,863 of the children were male, 1,583 female, 1,456 were from Syria, 1,016 from Iraq and 691 from Afghanistan. Similarly, for the calculation of vaccination coverage for diphtheria-tetanus-pertussis, poliomyelitis, pneumococcal disease, Haemophilus influenzae type b and hepatitis B that refers to children 0–4 years of age (n = 1,509), the following denominators were used: 775 children were male, 698 females 727 were from Syria, 360 from Iraq and 278 from Afghanistan.

^b Coverage for more doses of the aforementioned vaccines (when applicable) was also recorded; however, the data was not presented here due to the low numbers of vaccinated children.

^c Information regarding sex was missing for 64 records.

^d Information regarding nationality was missing for five records. The other 375 children of 19 different nationalities are not included in the table.

^e Pearson’s chi-squared test p value.
