Interesting article in the NY Times about the problems the US will have in reaching 'herd immunity'. That could effect flights to/from there.
The article (also widely reported in other sources) discusses that the practical reality is that Covid 19 will continue to circulate and become a manageable threat. And that, in my view, is a very positive development and the very conversation that I hope is being held by the Fed government

What the future may hold
If the herd immunity threshold is not attainable, what matters most is the rate of hospitalisations and deaths after pandemic restrictions are relaxed, experts believe.
By focusing on vaccinating the most vulnerable, the US has already brought those numbers down sharply. If the vaccination levels of that group continue to rise, the expectation is that over time the coronavirus may become seasonal, like the flu, and affect mostly the young and healthy.
"What we want to do at the very least is get to a point where we have just really sporadic little flare-ups," said Professor Carl Bergstrom, an evolutionary biologist at the University of Washington in Seattle. "That would be a very sensible target in this country, where we have an excellent vaccine and the ability to deliver it."
Over the long term - a generation or two - the goal is to transition the new coronavirus to become more like its cousins that cause common colds. That would mean the first infection is early in childhood, and subsequent infections are mild because of partial protection, even if immunity wanes.
Some unknown proportion of people with mild cases may go on to experience debilitating symptoms for weeks or months - a syndrome called "long Covid" - but they are unlikely to overwhelm the healthcare system.
"The vast majority of the mortality and of the stress on the healthcare system comes from people with a few particular conditions, and especially people who are over 60," Prof Lipsitch said. "If we can protect those people against severe illness and death, then we will have turned Covid from a society disrupter to a regular infectious disease."
There is widespread consensus that the herd immunity threshold is not attainable - at least not in the foreseeable future. Read more at straitstimes.com.
