If you a job that pays $19 a hr, would you get the vaccine to keep your job?

most people have had covid by now. @PTCdresser57

@deathfairy worldwide, only 49% out of 8 billion have been vaccinated

so? i was talking about the amount of people that actually got covid, worldwide. @fernie2

@deathfairy No, not really. If that was the case we'd be seeing the same situations in highly vaccinated countries and scarcely vaccinated ones, instead some eastern European ones for instance (notably Romania) aren't doing any good at the moment.

@deathfairy don’t get involved

sweet, you read part of what i said and somehow twisted it to what i wasn’t talking about. @Elessar

@deathfairy Hmm? I was commenting this: "most people have had covid by now."

And made a logical implication - if that was the case, we'd be all over it, not only highly-vaccinated countries.

okay, i guess if each country had half its population vaccinated then it would apply better, and my point too would make better sense. @Elessar

@deathfairy Technically some countries measured (via sampling) the percentage of naturally infected people vs. vaccinated, notably England. As of this Summer, only a 10% or so of the sampled individuals had natural antibodies, iirc.

With Delta you need ≥95% of the population immunised in one way or another, therefore 80-85% to be vaxxed, after counting the naturally infected.

@Elessar a recent study shows that 83% of Americans have some form of antibodies.

I don’t know where you get the >95% number. I had never heard that.

If you live in an areas where vax rates are high, then the risk of not getting vaccinated is low.

It’s the other areas where vax rates are low that one should be concerned

@JoeyFoxx The threshold required for herd immunity is in function of the R number which is much higher for Delta as it was for Alpha and wild type. Here it's stated 90% with a mean R of 5, but I think I've seen 95% on some other source (will update if I find the link):

[quote]A reproductive number of 5 would mean that vaccine coverage rates above 80% will be needed based on the equation q=1–1/R0, assuming a 100% vaccine efficacy. However, with decreasing vaccine effectiveness associated with the Delta variant,6 vaccine coverage rates above 90% will need to be achieved to contain Delta outbreaks. [/quote]

Obviously the situation is worse when the vaccination rate is, like, 30%. But still. It'll be interesting to see how it'll evolve even here, in terms of immunity waning especially.

@Elessar based on a model calculation I found yesterday, it’s statistically impossible to get better than 95% herd immunity, so, something isn’t right here.

As far as I can tell, what I commented above is correct: there are many communities that have already reached herd immunity and it’s due to a mix of infection rates and vaccination rates.

@JoeyFoxx There are many communities that are no longer seeing seeing hospitalization surges, but none as far as I know that are actually seeing proper "herd immunity".

@Elessar I don’t know of anyone who is trying to measure herd immunity (aka herd mentality 🤣)

@JoeyFoxx No, you have herd immunity when a certain disease can no longer find hosts, because a significant majority of the population is immunised. Measles has a much bigger R number than SCV2, and herd immunity is still achieved. We just need more efficacious and longer lasting vaccines (or to find out how many doses we need of the current ones in order for them to protect the most).

My rural western county (35% vaxxed and no masking), has the highest hospitalization since it began and the rate of death has exceeded last winter's worst. We are running a month ahead of last years winter wave, so will likely surpass since folks will come together for T-Day and Xmas holiday. Vaxxed can still "get" the disease since vaccinations arent force shields - they just help body fight it quickly, often asymptommatically.

Reinfection runs higher in unvaxxed, but still occur. I am masking so I do not unwittingly carry it to others. I got a booster... even suffered a couple days from a potent innate immunity response.

@deathfairy Folks can get reinfected. Also, one can be asymptommatic and spread it. Far from all being safe with herd immunity. That now requires REALLY high numbers with Delta's R0.

@Neoerectus Before Delta, vaccines seemed to work wonderfully at preventing infection/transmission as well. I'm curious to see what happens once a sufficiently large percentage of the population has received dose #3.

@PTCdresser57 the vaccine does not prevent covid nor does it stop the spread.
