https://www.sciencedaily.com/releases/2019/05/190521075055.htm Researchers at McMaster University have invented a stable, affordable way to store fragile vaccines for weeks at a time at temperatures up to 40C, opening the way for life-saving anti-viral vaccines to reach remote and impoverished regions of the world. The new method combines the active ingredients in existing vaccines with a sugary gel, where they remain viable for eight weeks or more, even at elevated temperatures. The method creates light, durable, and compact doses that would be ideal for shipping Ebola vaccine, for example, to affected regions of Africa, the researchers say. The process adds only marginal cost to preparing a vaccine and eliminates almost all the cost of transporting it -- which can account for 80 per cent of the total cost of inoculation.
The same principle was used to preserve foods before refrigeration. Bacteria has trouble growing in preserved food that has a very high sugar content and low water content, typically sticky thick consistencies. My only concern is whether all this sugar might pose some danger of blood sugar spikes (keep in mind you would be injecting a very high concentration of sugar directly into someone's blood).
Probably. But its a lot easier to infect a lot of ppl with a small amount. The cost of transportation is likely a lot less of a problem on the infection side.
