A clear child vaccination schedule, from infant through grade school.

The first year typically includes Hib, pneumococcal, hepatitis B, rotavirus, DTaP-based combinations, and BCG, often delivered within tight intervals. Combinations are common, but minimum spacing rules between specific vaccines still apply.

Enter the child's date of birth in Kigen and the routine schedule appears, age-anchored, so the next visit is one tap away.

Between ages one and three, boosters, MMR-equivalents, varicella, and Japanese encephalitis (1st series) come into the picture. Several of these have first and follow-up doses spaced months or years apart, which is exactly when 'I thought we did that one' starts happening.

Snap the immunization record pages and Kigen reads what's already complete and what's still due, surfacing only what's outstanding.

• MMR-equivalent: first dose around age one
• MMR-equivalent: second dose in the year before grade school
• Japanese encephalitis: three doses spread across years
• Varicella: two doses spaced at least three months apart

Mumps, influenza, hepatitis A, and others are common optional vaccines. Pre-school and daycare communities often expect them. Some local programs subsidize, others don't — keeping a per-region note next to each vaccine helps avoid surprise costs.

With siblings, each child sits on a different point in the schedule. Kigen lets each child be a profile of their own, while the family sees all of them on one screen. Assigning the parent on duty for each visit cuts the recurring 'whose turn is it' debate.

Daycare, kindergarten, and primary schools sometimes request vaccination certificates. Keeping the immunization record pages photographed in Kigen means the next request takes a few seconds to fulfill, not a search through a desk drawer.
