Development & Preventive Care
3 calculators · developmental quotient, vaccination intervals, catch-up vaccinations
Here you will find calculators for development and preventive care: the developmental quotient according to Gesell from developmental age and chronological age, as well as two vaccination calculators based on the Austrian immunization schedule 2026/2027, the earliest date of the next vaccine dose and the catch-up vaccination schedule according to tables 7–9. The vaccination calculators check, among other things, minimum intervals, minimum and maximum ages, and the rule for live vaccines. They are intended for interpreting a developmental test and for planning missing vaccinations. Each calculator states its formula and sources.
-
Developmental quotient (DQ)
Developmental age / chronological age × 100 – ≤ 70 marked delay, > 70 to < 85 borderline, ≥ 85 age-appropriate -
Vaccination interval – earliest date of the next dose
Minimum interval to the next dose according to the Austrian immunization schedule 2026/2027, with maximum age (rotavirus) and live vaccine rule -
Catch-up vaccination schedule (Austrian immunization schedule)
Missing doses of the standard vaccinations by age group (1 to under 5, 5 to under 18, from 18 years) based on documented vaccinations – with STIKO note
Frequently asked questions
How do I calculate the developmental quotient?
The Developmental quotient (DQ) calculator computes developmental age / chronological age × 100, using corrected age in preterm infants. The classification is: ≤ 70 marked delay, > 70 to < 85 borderline, ≥ 85 age-appropriate.
When is the earliest date for the next vaccine dose?
The Vaccination interval calculator determines the earliest date according to the Austrian immunization schedule 2026/2027 from the vaccine, dose number and date of the last dose. It checks minimum and maximum age (rotavirus) and reminds you of the 4-week interval between live vaccines not given at the same time.
How do I create a catch-up vaccination schedule?
From the date of birth and documented doses, the Catch-up vaccination schedule calculator compares the recommended number of doses for the age group with the doses present and gives the catch-up schedule with intervals, according to tables 7–9 of the Austrian immunization schedule 2026/2027.
