Abstract :
Vaccines have become effective in protecting
the health of a population. Vaccine development is a
challenge, ensuring safety of the vaccine from its source
until it is administered is another. One crucial part in the
cold chain system is the transportation of the vaccine
carriers from the health centers to poorly accessible
communities. The Philippines’ Department of Health
(DOH) Vaccine, Cold Chain and Logistics Management
Manual of Operations recommends actions in order to
safely deliver the vaccines with the use of WHO
prequalified passive containers such as vaccine transport
box and vaccine carrier. This research provides an
option to vaccine carrier for use when delivering vaccines
from health centers to poorly accessible communities
where government health personnel are deployed to
administer vaccines to newborn, bedridden, disabled and
elderly with mobility issues. The use of the current
vaccine carrier requires the use of at least six pieces of ice
packs, trained and highly skilled health care personnel
capable of manually taking, monitoring and recording
vaccine temperature in the course of delivery to the
vaccination site. This research output provides not only
an alternative design to the vaccine carrier but also a
prototype. The prototype is capable of maintaining
vaccine temperature within the target range, minimizing
risk of temperature damage; taking and recording of the
temperature of the built-in dummy vaccine; and
eliminating the opening and re-opening of the vaccine
carrier’s lid in the process. The capability of the
prototype in taking, monitoring and recording of the
temperature was tested to last for at least a continuous
12-hour duration at a 3-second interval. The prototype
can support the cold chain system requirement of
temperature monitoring every 30 minutes during the
delivery of vaccines from the health centers to poorly
accessible communities.
