Vaccine transportation and potency (active life)for proper administration is a challenge. This is due to the difficulty in retaining temperatures needed for their movement and distribution before being administered by virtue of the transport medium or vessel. Also faced with this challenge of proper conditioning before use is the movement of blood from bank to bank and its subsequent administration to the patient. The same hold sway in the movement ant transplant of human organs.

In order to improve healthcare delivery, minimize waste of vaccines, blood, and harvested organs intended for the improvement of the quality of life of the affected persons, it is very germane to provide field practitioners with a work/service mate for proper temperature conditioning. This is found in the novel CUWAVAC.

The product is novel since it’s a versatile well lagged bag deployed exclusively or as an appropriate add on to product transport kits for appropriate temperature conditioning. Under direct heat of the sun, frozen products can survive 24 to 72 hours. Present vessels can hardly last 24 hours continuous use in the field. It can be made of various sizes and shapes. Also, it retains cold temperatures; preserve frozen products; conserve energy and would improve Health care delivery.

This product would find ready use in the Health Industry(hospitals and care givers), Vaccine transportation and administration, movement of blood from one blood bank to another, extension workers(Vet/animal care practitioners), vaccine administrators on WHO projects(vaccine transportation for administration for WHO/UN and other National/International immunization projects, polio inclusive). Also, it could be used in displaced persons camps and intervention in rural and remote areas.

The market potential is huge considering the national and international sphere, the various national and international demands for the movement of vaccines, blood and organs. Also the critical rise in violence and billions of displaced persons needing various forms of health care and the complications in the protection of human and animal rights including the rights to care makes the possible demand and market potential for this product huge. With this product, improving the quality of life; preventing and reducing injuries, reducing waste, bolstering the economy, and enabling other product improvements is a done deal.

This product employs the retention principle or the principle of conservation of energy. When products are conditioned to be cold or frozen, it is desired that this state is maintained or retained to a high degree of efficiency. With this properly sewn insulated bag this is guaranteed – temperature retention for between 95 to 96 % with the containment volume charged for between 80 to 100%. The conditioned products introduced to the bags can be further aided when charged with ice – packs for a minimum of 48 to 72 hours.

The materials shall be sourced locally and bag manufacturers engaged to produce them according to specifications, dimensions and components. However, partnerships, cooperatives, women and youth groups could be engaged to produce them. The production cost is favourable compared to other costs of similarly but low efficient products.
