FEFO principle
first expiry, first out
A fully immunized child has how many doses and how many months
Received 3 doses at the right scheduled intervals in less than 14 months.
a completely immunized child CIC how many doses and how many months
Received 3 doses but not at the right scheduled intervals for more than 14 months.
DPT, hepatitis B and tetanus toxoid vaccines can all be damaged by freezing. By shaking two vials, side-byside, one that might have been frozen and one that has never been frozen, health workers can determine if a vaccine has spoiled
4 the shake test
what damage the vaccines
- Any defect in the cold chain.
- Out date expiry.
- Using skin antiseptic at the site of injection (e.g. BCG).
- Using the reconstituted vaccine (MMR, measles, BCG) after the recommended period ( 6 hours).
- Exposure of the vaccine to unacceptable temperature during the immunization session.
- Exposure of the vaccine to direct sunlight (BCG)
Involves calculation of eligible population for immunization services
target setting
Accomplished using Field Health Service Information System (FHSIS)
EPI Recording and Reporting
Consists of any group of people targeted for specific immunizations due to their susceptibility
