Fact Check: "Covid vaccine is dangerous"

What We Know

The claim that "Covid vaccine is dangerous" has been a topic of significant debate. Various studies and reports provide insights into the safety and potential adverse effects of COVID-19 vaccines. According to a safety update from the CDC, while there have been reports of adverse events following vaccination, the overall incidence of serious adverse events remains low. The report specifically notes that most reported events are mild and resolve quickly.

A review of vaccine safety among special populations indicates that certain groups, such as pregnant women and children, have been monitored for adverse effects. This review found that while there are some reported severe events, such as lymphadenopathy and autoimmune disease flare-ups, the overall risk of serious adverse events is low, particularly in children and adolescents (source-2).

Furthermore, the FDA has acknowledged specific risks associated with mRNA vaccines, particularly relating to myocarditis and pericarditis, especially in younger males (source-6). However, these risks are still considered to be outweighed by the benefits of vaccination in preventing COVID-19 and its complications.

Analysis

The evidence surrounding the safety of COVID-19 vaccines is extensive, with numerous studies and safety monitoring systems in place. The CDC's safety update highlights that while adverse events have been reported, they are relatively rare compared to the number of doses administered. The review of special populations (source-2) provides a comprehensive look at the safety profile of vaccines in groups that may have unique health concerns, reinforcing that severe adverse events are uncommon.

Despite the acknowledgment of risks such as myocarditis, the FDA's updates indicate that these events are rare and that the benefits of vaccination, including the prevention of severe illness and hospitalization due to COVID-19, are significant (source-6).

While some reports may sensationalize the dangers of vaccines, it is essential to consider the broader context of vaccine safety data, which consistently shows that the benefits of vaccination far outweigh the risks for the general population.

Conclusion

Verdict: Partially True
The claim that "Covid vaccine is dangerous" is partially true. While there are documented adverse effects associated with COVID-19 vaccines, the majority of these effects are mild and transient. Serious adverse events are rare, and the overall safety profile of the vaccines is favorable when weighed against the risks of COVID-19 itself. Thus, while there are risks, they do not substantiate the claim that the vaccines are broadly "dangerous."

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.

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
