They are establishing the protocol for prioritizing who gets it first. Is it possible for people to end sweep this process.......sure but what is the net effect? It sounds like first vaccines are coming out shortly and that over the next six months pretty much everyone "that wants it" will have access to it depending on what country you live in of course. Canada has a goal to try to get to 70% of our population vaccinated by September of 2021. I assume that is more than 100% of the people willing to take it?
"Based on that
advisory group’s preliminary guidance, the recommendation is that essential workers and others who face increased risks related to COVID-19 should be vaccinated against the disease before everyone else. Examples of those at higher risk include providers of essential services, or those whose living or working conditions put them at higher risk."
They will have an agreed to system of priorities in place and everyone's going to get their crack.
