Fact Check: "Is Covid lab made?"

What We Know

The origins of COVID-19 have been a subject of intense debate and speculation since the pandemic began. The two primary hypotheses regarding the origin of SARS-CoV-2, the virus responsible for COVID-19, are the natural zoonotic spillover theory and the lab-leak theory. The zoonotic spillover theory posits that the virus originated from animals, likely bats, and was transmitted to humans through an intermediary species, a scenario supported by genomic analyses and evolutionary studies (source-1). In contrast, the lab-leak theory suggests that the virus may have accidentally escaped from the Wuhan Institute of Virology (WIV) during research involving coronaviruses (source-2).

Circumstantial evidence has been cited in support of the lab-leak theory, including reports of early COVID-like symptoms among WIV researchers and the proximity of the initial outbreak to the laboratory (source-1). However, it is important to note that the viruses used in experiments at WIV were not complete, infectious particles, and Dr. Shi Zhengli, a prominent researcher at the institute, has consistently denied any connection between the lab and the virus (source-1).

Analysis

The debate surrounding the origins of COVID-19 is complicated by the lack of definitive evidence supporting either hypothesis. The zoonotic origin theory has garnered more scientific support, with numerous studies indicating that similar coronaviruses have been found in bats and pangolins, suggesting a natural pathway for the virus's emergence (source-2). However, the lab-leak theory cannot be entirely dismissed, as the early symptoms reported by WIV researchers and the laboratory's research focus on coronaviruses raise valid questions about the potential for an accidental release (source-1).

The credibility of sources discussing these theories varies. Peer-reviewed scientific articles, such as those published in Nature Medicine and Science, provide a more reliable basis for understanding the origins of the virus compared to news articles or politically motivated statements (source-2, source-4). Furthermore, the political context surrounding the lab-leak theory, including statements from government officials, may influence public perception and scientific discourse (source-1).

Conclusion

The claim that COVID-19 is lab-made is Partially True. While the lab-leak theory presents some circumstantial evidence that warrants further investigation, the predominant scientific consensus supports the natural origin hypothesis. The lack of conclusive evidence for either theory means that skepticism and inquiry should continue, but claims of a definitive lab origin are not currently substantiated by the majority of scientific research. Therefore, while there are elements of truth in the lab-leak theory, it remains one of several hypotheses that require further exploration.

Fact Check: We have 50 years of data that tells us what corporations do with tax cuts. This has been one of the most studied things by universities around the world for the last 50 years. And in the last 50 years across 18 of the wealthiest nations in the world not one has corporate tax cuts equated to higher job growth. 00:35 Not once. Or we can just look at the Trump tax cuts passed in twenty 17. Donald Trump created 40, 000 less jobs a month than Barack Obama did. And oh by the way that's leaving out COVID. That's leaving out all the job losses from the pandemic. There is one thing that happens when you give corporations big tax breaks. This right here. 50 years of data. You see that red line on top? That's the rich getting richer. You see those two lines on the bottom? That's the bottom 905percent? No In 01:06 twenty 18 corporations spent over a trillion dollars on stock buybacks and created less jobs than they did in twenty fourteen, 15, 16, and seventeen. You see the rich can afford to pump all of this misinformation into your brain. And that's why you believe it. There's not a single case in history of tax cuts for the rich helping an economy in any way shape or form.

Fact Check: Covid nimbus. Here's the symptom you need to know about that nobody's talking about. What's that? You haven't heard of COVID nimbus? Probably need to talk about that too. So let's get to it. Stick to the end. I'll talk a little bit about prevention. So COVID nimbus is the newest variant going on. It is NB. 1. 8. 1. Say that three times fast. And the unfortunate part about this is it looks like it's more contagious than other variants that we've had recently but it doesn't look so bad that it's going to wind you up necessarily in the hospital. But if you followed me at all you know that that's not necessarily the worst thing 00:32 that happens. You can still develop long COVID from any COVID infection that you get no matter how serious it is or not. But it has a gnarly symptom we have not really seen with COVID in the past. And it mimics other things that we see this tiny year so it's going to be even more important that you test for it when you start getting sick. And it's being associated with razor blades. I know it's not from when you pee so don't worry about that one. Don't go down that road. It's at being associated with the sensation of swallowing razor blades because it causes such a severe sore throat it is akin 01:06 to that sensation. And that can be a similar symptom to a lot of other things particularly things we see in kids like strep throat. Or in older kids things like mononucles. Which you also see surges in usually in summer. But prevention things seem to work the same as they've been working. So vaccinate and if you can get a booster and you haven't like in the last three to six months talk to your doctor about doing so. If you are at high risk and have autoimmune issues or autoimmune suppressants do like I did which is get monoclonal antibodies to protect you
