Epidemic coronavirus infections have dropped by almost half in the last one month worldwide. Vaccination has started in many countries. However, even if the vaccine is not going to say when it will be wiped out! The European Union's (EU) disease control council has expressed similar concerns.

The agency says the epidemic could rule the world indefinitely. Andrea Ammon, head of the European Center for Disease Prevention and Control (ECDC), said the vaccine had arrived and could not be seen lightly.

It is clear that the virus can easily mutate among itself.

As is the case with the flu. One thing is clear from all this, the virus is not so easily eradicated from the earth.
