Actions:
DTP dose 1 (delayed start): Provision of DTP dose 1 with a delayed start Trigger event: No DTP doses were administered and client's age is more than 1 year Trigger pseudo: Count of vaccines administered (where "Vaccine type" = "DTP-containing vaccines") = 0 AND Today's date − "Date of birth" > 1 year Trigger date: Date of birth Create condition: For children whose vaccination series has been interrupted, the series should be resumed without repeating previous doses. Children aged 1 year to under 7 years who have not previously been vaccinated should receive 3 doses of vaccine following a 0, 1, 6 month schedule. If tetanus vaccination is started during adolescence or adulthood, a total of only 5 appropriately spaced doses are required to obtain lifelong protection. Pregnant women and their newborn infants are protected from birth-associated tetanus if the mother received 5 doses if first vaccinated during adolescence/adulthood.
