its not going to be that easy.. especially with all thosse terrorist minds refusing to wear masks etc

That was proposed here by one infectious disease processor. Though got no traction

On the summer solstice there was talk about a national holiday... makes economic sense as you point out

You would expect the pandemic in terms of death rate to be subdued in the northern hemisphere by April to august
As the population has immunity or at the least less symptomatic
Reasoning:

1) already infection population... varies by country but could be 5-20%. There is at the least evidence of antibody and tcell immunity in those studies and reinfection rates appear low so far

2) cross immunity... tcell immunity from beta coronaviruses potentially a big influencer and not discussed in media... this was a game changer in swine flu 2009 (acknowledged by ECDC and WHO)
A very good article appeared in the British medical journal in September 17th about this)

3) vaccine... when given to the vulnerable the death rate will drop rapidly as expected (the second wave here was 90% less deathly than the first)

4) northern hemisphere seasonality, expect from April onwards

SARS-COV2 is a nasty respiratory disease for some. Basic public health measures are important and work
Reduce contacts, wear masks and wash hands basics

Hopefully in time the natural course of the pandemic (deaths over cases) will play out and the shape of the course and curves will be similar (albeit larger) than the swine flu 2009

You are unrealistic. This won't be over by then. Celebrate each day now. Live in the moment. The future is never guaranteed.

Eh, it's taking way longer than I initially hoped when you've first made this post as well. Almost there however, I'm hoping for a relatively normal Christmas this year (at least for those of us who are fully immunised)

Blue states will continue what they are doing. A prosperous country can’t be a socialist country ... and the libs desperately want to destroy America as founded

It's a great idea but I think summer might be too soon.
It will vary from country to country depending on the take up rates for the vaccine and the public's willingness to follow guidelines and restrictions.

Well here we are just over 3 months later and things have slowly but surely gotten better over here where I am. I don't think numbers of cases will be low enough by May or June to go back to normal though.

A lot of people do - it's called the Summer Solstice. Xmas is really just a christian attempt to christenize the celebration of the Winter Solstice and similar Pagan festivities at that time of the year.

On a fiscal front, do you expect businesses to give people more paid time off for this extra holiday?

It will take more than a few months to get anywhere close, in fact they warn us that the worst is still ahead of us before it turns for the better.
