Hi @juanmolina
I'm afraid this pandemic situation could even continue for this year. Because of what you mention. And also I think that those vaccines that are being applied, although they are effective against the original strain of the virus, may not be the same in those that are already and much less in those that are going to emerge. So all this leaves us with a rather complex panorama.
We still have to be careful, keep inventing things to produce in case all this goes on for much longer.
Which is most likely.
That's right, my friend, even scientists have a lot to experiment, a lot to discover, to achieve an optimal level of immunization.
In the meantime, it is up to us as a population to adopt the preventive measures.
