Not the OP, but 1) officials in several EU countries have recently said that restrictions will probably exist until very late 2021, because even in a best-case scenario not enough of the public will be vaccinated until then. I personally would not accept borders being closed for so long among fraternal European countries. Even more seriously, the mass events and ordinary courtship opportunities that are so important for young people coming of age, should not be put off so long. (I am most opposed to lockdowns because I think it is the biggest betrayal of young people since ’68.)

As for claims of “long COVID”, these are largely unverified and a media creation. (Clinical studies do exist, but the definition of “long-term symptoms” used among specialists is often not as dramatic as the one found in sensational newspaper coverage.) Many of the people claiming to have the condition have never even tested positive for COVID, and it can be seen as broadly the same demographic that, before this epidemic, claimed to have “chronic Lyme” in the complete absence of any evidence.
