A vaccine is one way to help get to herd immunity if it is even possible. Experts who originally said there was no herd immunity possible for CV19 are now
talking about herd immunity as if it were possible. This is before there is any real proof one way or the other.
My advice, logically, to all is to wait for actual results from vaccine testing which should be available in 2022.
My understanding of herd immunity is all safeguards are removed and its basically let it kill those it will and the animals left get herd immunity.
Respected experts have denounced herd immunity as "dangerous and nonsense".
It is a 100 year old theory misapplied from agriculture.
I am not aware it has ever worked as theorized in humans.
People who reject masks, curfews, social distancing, hand washing and demand immediate reopening of business in general are herd immunity supporters whether they realize it or not.
In order to be in the testing process the vaccines must have already shown they are effective.
The trials are not to determine effectiveness but to ensure safety.
Imagine a vaccine that protects you against CV19 but leads to increased heart disease.
They know the vaccines work or the companies would not be spending millions of dollars to test.
Even when a vaccine has proven to work without any side effects there will always be naysayers who refuse to take it.
Annual flu vaccine is only taken by about 50% of the population and its safety and efficacy is beyond question and there are years of problem free experience as proof.
It will be very interesting to see how many people will get a CV19 vaccine shot.
It may well be that we will need much less of the vaccine than anticipated which will facilitate distribution.
The world will always have those that row upstream.
Look at how many people in the DR that smoke in the face of the overwhelming evidence.
People are fascinating.
