In My Opinion, This Is One Of The Best Ideas...EVER: A Practical Vaccine

A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains a small amount of an agent that resembles a microorganism. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.
There are several methods in which a vaccine can be administered. They can either be administered orally, via a microneedle and/or syringe. Many vaccines need preservatives to prevent serious adverse effects such as the Staphylococcus infection that, in one 1928 incident, killed 12 of 21 children inoculated with a diphtheria vaccine that lacked a preservative. Several preservatives are available, including thiomersal, phenoxyethanol, and formaldehyde. Thiomersal is the more effective of the 3. It fights against bacteria, has better shelf life, and improves vaccine stability, potency, and safety, but in the U.S., the European Union, and a few other affluent countries.
With that being said, researchers at the University of Tokyo, Institute Of Medical Science, plan on a creating a vaccine that combats infectious diseases like AIDS and influenza but doesn't require a syringe or refrigeration. How will they do this? you may ask. Well, they plan on developing MucoRice, a rice-based oral vaccine that provides layers of immunity against infectious diseases but doesn't need to be refrigerated.
I think this is a great idea b/c as a cereal grain, rice is the most important staple food for a large part of the world's human population, especially in East, South, Southeast Asia, Latin America, and the West Indies. It is the grain with the second highest worldwide production, after maize ("corn").
Since a large portion of maize crops are grown for purposes other than human consumption, rice is probably the most important grain with regards to human nutrition and caloric intake, providing more than one fifth of the calories consumed worldwide by the human species.
Therefore, if you combine rice and a vaccine that combats infectious diseases you have a combo that can't be beat. First and foremost, you'll have a widespread effect due to the worldwide consumption of rice by the human population. Second, you'll be fighting diseases that kills a significant amount of people per year. Lastly, you'll be making a difference. And in the end, that's all that really matters...at least to me, that is. What do you think?
