Well.
That just let the air out of my sails.
*sigh*
The vaccines are a HUGE step forward. The situation will likely be a LOT better 6 months from now.
They're definitely not a complete fix but let's not that fact stop us from celebrating them and the people who created them.
I suspect that huge events like Gen Con will still not be allowed, but at least I'll probably be able to play at my game store :-)

But, assuming we can get decent compliance, herd immunity will kick in even with a relatively short effective time. The caseload will drop drastically and we'll see any resurgences as new outbreaks when immunity starts to decline.
Which will lead to more rounds of vaccinations. By then they'll have had longer to work and quite possibly have devised longer lasting ones.

From the National Institutes Of Health
The Long Road Toward COVID-19 Herd Immunity: Vaccine Platform Technologies and Mass Immunization StrategiesA threshold value of ~67% is estimated to be sufficient for achieving herd immunity against SARS-CoV-2, assuming that the basic reproductive number (R0) of the virus is three, i.e., one infected individual infects three new individuals (9). Based on this estimate, ~5.3 billion vaccine doses are required for a single-dose vaccine, or possibly 12–16 billion in case of a multi-dose vaccine. Therefore, it is clear that inducing herd immunity by mass vaccination would be an incredibly powerful tool to contain the COVID-19 pandemic, but it also represent a massive challenge.
