lol. I see what u trying to do. If you whole heartedly believe that a sample size of less than 1000 is a good enough representation of the target population for you to then say that beyond a doubt all people who recovered from covid should still get the vaccine then you do you. Let me put it another way, there have been about 203 million covid-19 cases. Using this information, keeping in mind vaccinated people and double cases, lets say 100 million unvaccinated people got the virus (very generous mind you). You now telling that 100 million people that even after they got anti-bodies following there battle with the virus they should still get the vaccine as my study of less than 1000 people (basically 0.001 per cent of the very generous target population) said so. LOL. Ok 'Mr. Scientist'
me? nah. I am still a budding researcher in social / information sciences. I've barely scratched the surface with sampling in SocSci, which is very different from clinical studies so they are not comparable at all. I just did a keyword search out of curiousity and a number of papers specific to medicine jumped out. Epistemology is a whole focus area by itself.
i not on your case. My comment is for adnj. I am also in social sciences. My Msc is in Financial Economics. And yes the two are very different fields (that is social sciences and medicine).

I was reading that study but I really wasn't understanding what they were saying. The highlight for the cdc is that persons who were infected previously and unvaccinated were 2.34 times more likely to get reinfected than people who had been infected previously and got vaccinated. So they use this as to basis to say that people who were infected previously should still get vaccinated.
Elec2020, What was the total sample size? How many unvaccinated got reinfected vs unvaccinated?
Researchers studied Kentucky residents with a lab-confirmed coronavirus infection in 2020, the vast majority of them between October and December. They compared 246 people who got reinfected in May or June of this year with 492 similar survivors who stayed healthy. The survivors who never got vaccinated had a significantly higher risk of reinfection than those who were fully vaccinated, even though most had their first bout of COVID-19 just six to nine months ago.

Isn't that how results are extrapolated into the wider area regardless of sample size?
In statistics you will never be able to capture your full target population. So yes, you extrapolate the results. Thats where margin of error comes in. Given that concept, you will have a ridiculous margin of error for conclusions extrapolated on a dataset that represents 0.001 per cent of your target population. Is that not a fair assessment?

what that has to do with capturing 0.001 per cent of the target population? You saying that, based on a sample that captures 0.001 per cent of the target population, I am 95 per cent confident that even though people who got covid got antibodies from it they still need to get vaccinated? LOL! Are you listening to yourself?

Many of them were not vaccine hesitant but sinopharm hesitant. They simply were not comfortable with it and were waiting it out until a better option came along and well... here comes AZ thanks to Canada. It's a recognized brand and more acceptable for foreign travel. Now if cases of delta were announced before AZ arrived, many of those persons who were sino-hesitant would have gone for the sino shot.
Now we saw today that more persons coming forward to be vaccinated, that's good. Now imagine if we received Pfizer instead, all vaccination sites would be ram out with mass traffic all over.

Thats the numbers they working with. The actual sample size is therefore 738, but to emphasize my points, I exaggerate the numbers against my favor and significantly curtail those in my favor.

It was available in extremely limited quantity (I think only 60,000 vaccines available for 1 million adults). This is the first time AZ has been widely available to the public, hence the big rush.

I dont understand that donkey logic cdc trying to bring there. Why they just don't say what are the chances of getting reinfected? Because that data would not support their vaccine slavery agenda.
And for those who going cuss me after, please just answer the question, what is the likelihood of being reinfected with covid-19?

TRINIDAD and Tobago is expected to receive its third tranche of covid19 vaccines from the Pan American Health Organisation (PAHO) on Wednesday.
PAHO's online tracker says TT will receive 33,600 doses of AstraZeneca on August 11.
On Tuesday, the Bahamas and Belize each got 33,600 doses of AstraZeneca from PAHO.https://newsday.co.tt/2021/08/08/paho-t ... nd-tobago/

so, you willing to trust the approval of the WHO, the same WHO that was & still is in bed financially with the original source country of this virus, even when said source country was caught openly lying to the world. The same WHO that has dragged their feet in investigating the original cause of this pandemic from the onset because of the fear that they would lose funding from one of their biggest financial supporters, which coincidentally happens to be China.

Somewhere near Cozumel in the Caribbean Sea, there’s a cruise ship that had zero unvaccinated people aboard but that still suffered an outbreak of Covid-19.
According to Health Ministry data published on Sunday, the number of seriously ill patients has jumped to 97 – an increase of 30 patients since last Wednesday. Of the seriously ill, 22 are in critical condition and 17 are on ventilators. In total, 191 coronavirus patients were hospitalized as of Sunday, of whom 113 were vaccinated.

But the number of seriously ill patients has risen much more slowly than the number of cases. The latter figure jumped from 132 to more than 1,400 over the last month, a tenfold increase. Over the same period, the number of seriously ill patients rose from 23 to 97, a fourfold increase.
Before vaccinations began, around four percent of patients became seriously ill. But today, with most of the country vaccinated, an estimated 1.5 percent of patients become seriously ill.

I spotted Sputnik for what it was early in this thread and got popped down.I can't get that so I got Sino which is better than not being vaccinated.Wouldnt have mattered which I got really.They all doing similar things .As with other things, statistics get skewed over time in terms of efficacy.

Elec2020,
The reason you get called out a lot is because you continuously try to sound educated when you make the most elementary mistakes. It's no surprise that other anti-vaxers are non the wiser with your rhetoric.
Firstly you can get very accurate results with small samples sizes. As the sample sizes gets larger the rate of improvement in accuracy declines so it makes no sense to use a sample size larger than 1000-1500 people when representing the entire population or subpopulation under study.
A sample size of this range, you can be confident that, 19 times out of 20, the samples division on a typical question will fall within 3 percentage points of the entire population's division.
Here's an example, if 45% of the respondents in a poll of 1500 say they approve of the president's job performance, chances are 19 in 20 that the actual level of approval throughout the whole U.S population falls somewhere between 42% and 48%.
You can sometimes be surprised how accurate small sample sizes hold up. Mathematically it was once proven that as little as 30 persons can reflect the population at large, mainly because of the assumptions on the Central Limit theorem. It's hotly debated though, but the fact is whether it's 30, 50 or 100. There is a lot of statistical power in small sample sizes.
https://www.researchgate.net/post/What_ ... statistics
What's important though is the statistical significance and in this study there is definitely a large statistical significance from the sample in Kentucky.
Regarding the CDC study, yea it's not peer-reviewed, it's an early release preprint, so we can't yet vouch for it's accuracy. However, it's likely already one through several checks and peer-review will just be a formality.
And small sample sizes are not an example of biased sampling. Bias sampling is using a non ramdom method of polling, for example using a Trinituner poll to predict the outcome of an election in Tobago East.
