The elite/UN in cooperation want everyone 'on' protocol.
This sounds to me like conspiracy tomfoolery. In terms of health, who is the "elite", and what is the UN doing to support them?
Globally we have health challenges. Diabetes is one, but the most obvious one to mention was Polio. Polio was a problem with global implications. That means every continent, Country, government, and healthcare system. It's a disease that can now be all but eradicated (it's been reduced by more than 99%). However, to do so took a global response. Someone had to coordinate, someone had to set up manufacturing for vaccines, someone had to deal with administration.
This was achieved through a few organizations, chief among them the UN and Wold Health Organization. They were, frankly, the only bodies that were able to help everyone come together and work on solving this health disaster. Point being, there are times when we need those organizations to cut through red tape, and gain a common understanding and agreement. With Polio, it worked wonderfully.
There are also basic health statistics such as diabetes, Chicken Pox, and a host of other things that don't vary too much country to country, and therefore can have health protocols written and applied at a global level. For example, we do know that blood pressure is an important diagnostic measure. So yes, it's part of the the protocol when testing. Treatments, and even recommended acceptable levels of blood pressure, are NOT globally agreed, however. For instance, the European Society of Cardiology isn't in complete agreement with the WHO. This is due to several reasons, including local ability to deliver healthcare and yes, a disagreement on interpretation of data.
In other words, having an organization with a global view is important and necessary. Not for every little thing, of course, but because we're a connected world.
