Table 1 Distribution of coverage in 12–23-month-old children and time of vaccination among those with a vaccination card according to vaccine studied (Kecioren District, 2007)

	Coverage (%)	Vaccination age was detected (%) (n)§	Appropriately timed vaccinations (%)*	Vaccination Month†
				Mean ± standard deviation	Median (25%;75%)
BCG	99.4 (63.9)	54.6 (n = 603)	87.2	2.35 ± 0.93	2.20 (2.20;2.47)
DPT-3	98.5	53.4 (n = 584)	67.0	5.08 ± 1.75	4.60 (4.30;5.33)
OPV-3	99.4	53.0 (n = 585)	63.9	5.06 ± 1.35	4.67 (4.33;5.47)
Hepatitis B-3	97.3	52.4 (n = 566)	79.2	8.97 ± 1.72	9.20 (7.80;9.73)
Measles	93.9‡	6.0 (n = 63)	77.9	9.43 ± 0.68	9.47 (9.10;9.80)
MMR		41.9 (n = 437)	76.3	12.85 ± 1.12	12.47 (12.30;12.93)

* Nationally recommended vaccination age is 2, 3, 4, 9, and 9/12 months for BCG, DPT-3, oral polio-3, hepatitis B-3 and measles/MMR vaccines, respectively. These months are regarded as "appropriately timed vaccinations" in the study. Percentages were calculated out of total number of children for whom vaccination date was available, as given in parentheses in the second column of the table.
† As obtained from vaccination card (if available).
‡ Child had at least one dose of either type of vaccine against measles (monovalent measles or MMR).
^§ Percentage gives the proportion of children who were reported as vaccinated for the given vaccine and for whom the vaccination date was detected at the time of the interview. Numbers in parentheses are the number of children for whom vaccination date was detected.
