( Could Logmore's Dry Ice Transit Solution Be the Answer to Covid Vaccine Delivery? ) The formulation of a safe, effective COVID-19 vaccine is one thing, but its distribution to potentially billions of recipients is quite another. Make no mistake, transportation at sucha scale will entail a complex logistical operation, a consequence of the ultra-low storage temperatures required to preserve each and every dose. As the life-saving vaccine journeys by land, sea and air from laboratories to distribution centres - and then onward to clinics, pharmacies and hospitals - the deep-freeze delivery chain, also known as the "ultra cold chain" will shoulder the burden of optimizing conditions. The stakes couldn't be higher - the prevention of millions of deaths and the reopening of society ultimately depends on their success.
