Herd Immunity is so BADLY understood, and subject of innumerable lies, misinformation and myths.

There's CONSTANT hammering on simple ideas from fear propaganda. Main lie is we haven't reach HI, we're far away from it, as we need a 60-70%

Let's bring some scientifical light.

HI is considered a binary issue, you have it or not. That's BLATANTLY a lie.

With EVERY SINGLE infection, HI grows&provides some degree of common protection, as any infected will die or, over 99%, survive.

Both ways he gets out of any transmission chain.

It will slow any epidemic transmission & make the Rt descend

Proportional to HI growth, spread ALSO slows

Even in the SO WRONG 70% theory, 5% diffusion will slow spread, bigger ones like 15 or 20 will SERIOUSLY affect it

The NON exponential growth, but Gompertz, reflects this

If you're A TRUE scientific like @SunetraGupta or @mgmgomes1 you'll find that this growth affects SO dramatically transmission chains, that a certain point, those more likely to infect many become immune, or die, and provoke a bottleneck making the epidemic to stop.

HI threshold

U only have to consider that were all not equal, that ones are more prone to get infected (+contacts,-defences), some are more likely to transmit (+contacts); and u MATHEMATICALLY will find that a HIT 10%~25% will (IS!) happen.

No way u reach 70 without burning the bottleneck

Climate conditions put different limits for HIT needed, thus making seasonality+HIT the true regents for the epidemic

HITs lower than 5% are enough to stop epidemic in moderate climate summers. We've already seen it

When weather becomes better for virus again, it may come back

The fear official narrative is attacking and trying to silence this science, even thru personal attacking as censorship, as the sad story of those 2 brave women shows. Just check their TLs

It's our duty to struggle this good science to enter on the debate RIGHT NOW

Here it goes

Herd Immunity Threshold can be reached with low (>20%) infection rates.
You don't have to fully reach any limit to grow protection from HI, and any close you get to HIT protects society and slows spread very fast.

70% needed and any HI being useless till u reach it IS LIE.

HI isn't a good or evil policy, IT'S A FACT. It's happening ALL the time

Vaccination works THIS way, as there's people u can't vax, and avoiding contacts to infect, u protect them

As 70% is calculated thru 1-1/R0, they're lying given a number: R0 stills a highly debatable issue
