Kinda. You're failing to account for continued genetic mutation that will happen once the virus starts to get stifled a bit.I'm not sure that's the case.
60% effective with 75% of the country receiving it with continued social distancing for a few months should be the end of the pandemic and drop cases to almost 0 as long as the rate of spread stays low.
The virus won't find enough people to infect in the time (10 days or so?) that the carrier is contagious.
For example:
In IL the current rate of spread is 1.18
For every 100 people that get covid they're giving it to 118 other people.
Those 118 give it to 139 others.
139 give it to 164 others and so on.
Now with the same practices in place those 100 initial cases won't be spreading it to 118 others after 75% of the population gets vaccinated (at 60% efficacy.)
They'll be spreading to around 60 others.
And those 60 others will be spreading it to 32 others.
And those 32 will spread it to 17 others.
Within a few months we're basically down to 0.
(If my memory serves correct from Immunology, this is how it works.)
My math above is just for purposes of illustration. The actual models will provide actual numbers.
IIRC the flu vaccine is anywhere from 35-60% effective in a given winter. While a Covid-19 vaccine will probably be more effective, we've already proven that it's a year round disease that's especially devastating during the winter. As we vaccinate, we also have to watch how fast it mutates once the virus is stressed for reproduction. It could accelerate the process or stagnate. If it accelerates, then we have a flu situation where people are going to get sick regardless and there's only so much we can do. If it stagnates, then it can be slowed significantly.
If they have 7 genetic variants every 6 months on average, then they can target the most likely variants to vaccinate against. However, that leaves people unprotected against some strains. People would still need a summer and winter vaccine and people will still continue to get sick.
This thing is widespread enough that our best course of action is to slow it's spread as best as we can, but Covid-19 is just going to be a fact of life for decades, if not forever.
Most people when they get "the flu" they really have one of the 4 endemic human Coronaviruses known before 2019, one of which is the common cold. Actually getting influenza is really rare at this point.
