We already know that news about advances in science usually comes years before the issue in question becomes a reality. However, it is always nice to know at what time some research is found and what the future will hold.
If a few months ago we learned that over time children can be made analytical without puncturing them, these days we have learned that work is being done on new nasal vaccines that do not need refrigeration.
Involving
The implication in terms of health is wide. On the one hand, when administered nasally, they don't hurt as the vaccines we all know do. On the other hand, by not needing cold to be preserved, they can arrive to anywhere in the world in good condition.
Many diseases could be eradicated if the majority of the world's population could receive the vaccine. However, this seems difficult, or almost impossible, because current vaccines need to be kept cold. There are poor countries, so poor, that they have nowhere to store the vaccines cold and then administer them, so it is absurd to pretend that their population can protect themselves from anything.
Balaji Narasimhan, professor of chemical engineering at Iowa State University and one of the researchers, says the following:
Our nanovaccines can be stored at room temperature for six to ten months, and they continue to work ... We are also designing them so that they can be administered in a dose through a nasal spray, which could potentially allow patients to administer the vaccine themselves.
From these words we deduce that will be administered in a single dose, without the need for further reinforcements (this gives me doubts, really). As they comment, these new vaccines act in our body differently, affecting a different part of the immune system.
Rodent tested
To date they have only been tested with rodents and the results have been positive. The next step is to start using them with larger animals.
This, as we know, does not have to mean anything, since many times you get great results with animals and no benefit in humans.
So, we still talk about a nice experiment that could be revolutionary in a few years, or just something we will never hear about again. I hope it comes first.
