It was 84% for the original covid. Anything lower was a lie.
I think 70% was part of the original messaging based on general epidemiology statistics.
It was probably updated once we found out more about Covid-19 Alpha, and later for Delta.

Mutations were obviously going to happen from the get go. When questioned about this exact thing "experts" still stated that 70% would prevent this from happening, until they were wrong.

70% of non receptive surrounding people is enough to stifle any virus.
What changed was whether the surrounding people were receptive to infection and capable of spreading it.

Weird how the least receptive populations were dominated by delta first.

Yeah, no. It started in mostly unvaccinated India.

And rapidly fell off. It only dominated highly vaccinated places.
70% is enough for the original Covid. Covid moved the goalposts to Delta which needs different numbers. This is not experts moving the goalposts, this is Covid changing on us - as was always expected to happen and why experts said we don't know what % is required until Israel showed 70% was enough for the original Covid strain.
