True for now the vaccine does not prevent you from shopping or selling however I feel eventually it will lead to that. In fact there are countries eg. Sweden where employees cannot work without the microchip sized as a rice grain installed on the hands. The vaccine contains the same technology. What about business owners what will happen if they cannot purchase merchandise for resale or travel without taking the vaccine? I feel with the vaccine its not directly forced in terms of words eg. " You have to take it" but instead " If you do not take it" you cannot not work, travel or shop etc... In fact Germany, Hungary, Iceland and even Israel has already started placing persons on that "special list." This is big for countries that depend on bigger countries to feed its population.
