Many of us are familiar with vaccines. In the US where I live most of us have been vaccinated for major diseases such as whooping cough, Hepatitis A, measles, mumps, rubella, tetanus, diphtheria, the list goes on. However, due to our developed infrastructure and relative ease of access to medical care many of us have never worried about obtaining vaccines for our children or ourselves. This alone has contributed to some of the most startling gains in public health that we’ve ever seen.
In other parts of the world though, this is a very different story. Less infrastructure and fewer opportunities for medical care has made vaccinating large segments of the human population extremely difficult with serious consequences for those who are not vaccinated.
One major hurdle in the race to vaccinate the majority of people on this planets is the maintenance of cold-chains for vaccine delivery.
