How many people actually acquired COVID in the mRNA vaccine trials?

In the BioNTech vaccine Phase 2/3, it was 50 any time after the first dose, but 11 after the second dose.

Those were people who caught covid or people that had antibodies?

What does everyone think of the idea that there is an 80/20 rule in play for Coronavirus? Specifically, 80% of the infections come from 20% of the infected. I’ve heard some hearsay about it, but nothing conclusive; I was hoping someone knew either way.

From https://www.bbc.co.uk/news/health-54648734 "Covid test-and-trace: Is backwards contact tracing the way forward?" > "Coronavirus does not spread evenly. Most people who get the virus won’t pass it on to anyone at all. But a small number of people will spread it widely. Scientists estimate as few as 10% of infected people are responsible for 80% of infections." Based on this, they go on to explain why, if it's tru…

I read that is what the Japanese did from the start (backwards tracing), and it worked well at the time. Something like the 80/20 rule was mentioned, that a minority of infected people were responsible for the majority of the spread.

The virus hasn't yet mutated enough to make the vaccine not work against it.

We don't know that for sure, and it has 7 different (known) strains already. Why would this be any different than the flu in that regard? Besides, we already know there are a lot of ridiculous anti-vaxxers out there who will refuse the vaccine regardless. And a lot of those people are elderly or at risk! The longer this situation goes on, the less palatable shutting down huge chunks of society seems to me to be. If t…

I would like to know what is known, if anyone has it handy.

A colleague of mine was infected, became symptomatic and tested positive, and results took several days to come back. The whole time he was at home with his family waiting for results, he quarantined at home but had contact with his family. He tested positive, but they never did. More credence to the idea that some are super spreaders and some are not.

Meanwhile I met my family for 2 hours, I started having a fever and immediately quarantined myself to another location. I told them to open all the windows of the flat, they didn't take me seriously. They all got COVID-19 from me.

People are really enjoying WFH and don't want it to end. It's important to keep the fear strong. Meanwhile, I am baffled we didn't prioritize n95(or kn95) masks. Well... It's government, I'm not that baffled A significantly more rational policy would have been to prioritize masks with filters and for the less than 1/12 of elderly people who live with younger generations, move them into a hotel room and pay for food d…

They did. Production is up 5x. But factories take time to build.

Entire new types of filters have actually been invented this year, going forward humanity is going to have a lot more choices when it comes to high quality filtering masks.

Oh no, a fever!

I am pro-vaccines in general, but I'll refuse the Covid-19 vaccines.

Is there any real concrete — or at least scientifically backed — reasons why we’re continuing to see numbers rise, in spite of more lockdowns in place and more people (supposedly?) wearing masks vs. in previous waves where the spread and deaths seem lower than now?

This is especially baffling considering how much more prepared we are (or should be?) and how much more we (should) know about the virus now vs. before.

It seems like one or more of the following is happening:

- Actually fewer people are wearing masks, or are wearing them less vs. previously

- Even though lockdown mandates/recommendations are increasing, they’re not being followed/enforced as much

- Masks aren’t as effective as we think

- It’s spreading in other ways that we’re unaware of

I’d love an ELI5 of why we’re continuing to see record numbers of positive test rates + deaths + hospitalizations, in spite of (again, supposedly) more diligence with masks and lockdowns.

To be clear, I’m a strong believer in wearing masks and staying home (I almost never leave my house, and when I do, I’m wearing a mask), but it’s baffling and a bit frustrating to see the numbers continue to rise without anyone seeming to have answers as to why.

> in spite of more lockdowns in place

I've been to about 20 states during this pandemic and I have never seen lock-downs strictly enforced... and I don't blame them.

Patients who received one or two doses of the vaccine who later tested positive for covid.
