A leading virologist has stated that just wearing a mask is not beneficial, it has to be worn correctly or it will do more harm than good. It therefore follows that you just cannot turn out millions of masks to suit everybody, children, for example, would obviously need smaller ones. There is also the problem like 3M shipped masks to Germany and because 3M is an American company, the shipment was rerouted to America. France has also complained they cannot get the items they need because America outbids everybody.
