[Results of a computerized vaccination database]

To analyze vaccine coverage in children from Picassent in Valencia (Spain) and to evaluate the effectiveness of a new computerized vaccine registration program.

A computer equipped with our self-made Babyvac-2000 program, based on Microsoft Access was used. The 2,514 entries on children in our database were examined. The results were compared with those in other population groups.

Uptake was high: 100 % in 12 of the 15 age groups (according to year of birth). Coverage was as follows: diptheria-tetanus-pertussis (DTP)-oral polio vaccine was 100 % for 9 groups; the first dose of the triple virus vaccine was 100 % in 7 groups; full vaccination was between 96.2 % and 100 % for all age groups; vaccination at 6 years was between 91.6 % and 98.7 %, the second dose of the triple virus vaccine was between 72.2 % and 96.3 %; vaccination at 14 years was between 82.9 % and 87.7 %; hepatitis B vaccination in young children (from 1994 to 2000) was 100 % in 5 groups and was between 90 % and 98 % in teenagers; the Haemophilus influenzae type b vaccination rate was 100 % for children born between 1998 and 2001 and was between 74.3 % and 93.5 % for those born between 1994 and 1997; meningococcal group C conjugated vaccination was between 86.8 % and 100 % for children born between 1994 and 2001.

This computer program considerably increases uptake and vaccine coverage among children.
