On the other hand, COVID has a pretty well defined risk being that we've seen it for 2 years now, and it's from a familiar family of viruses. So, to be clear, you're saying that 2 years of observational data on COVID is conclusive because COVID is very similar to other viruses (SARS, MERS) which we have on decades of observational da…

I don't think this is so inconsistent, and I addressed this in my post. Such limited data is never ideal in making these kind of decisions, but I'd wager we know much more about COVID's risk than mRNA. As I understand it, the technology for mRNA is a few decades old, but this is the first time it's hit the market, is it not? If so, the risk is still in the process of being discovered.

mRNA vaccines were first published in 1989, so 32 years ago.

At this point we've vaccinated more people against COVID with mRNA vaccines than the number of people globally infected with COVID proper. At this point we know more about the risk profile of mRNA vaccines than COVID.

> Generally vaccines have a much longer trial and study period, this has been rushed due to emergency circumstances.

Yes, generally vaccines have a much longer trial period - with a tiny fraction of the participants.

The average vaccine phase II trial has 2,854 participants, and 29,844 in phase III [1]. So far, 4.62 billion doses of the COVID vaccine have been delivered. Since most are two-shot, we can generously round that down to 2,310,000,000 people in this 'trial.'

'Rushed' is the wrong way of looking at it. It went faster, yes, but there's a reason. Since you can't knowingly infect people with ebola to test the efficacy of an ebola vaccine, you get a few thousand people, immunize them and then you wait. And wait. And wait. During the massive outbreak in 2014-2016, only 28,000 people in the world caught it.

On the other hand, by mid-2021 17% of America had caught COVID.

Proving it worked was a much faster exercise.

That it went faster doesn't mean it's less safe, and it certainly doesn't mean isn't effective. It only went fast because it was possible to prove its efficacy so quickly.

The data is clear: hospitalization rates are 15-200X higher in the unvaccinated and death rates are 8-87X higher. Even with Delta. [2]

Why do you think getting it to market faster means its less safe?

> I still disagree that I'm exposing myself to more risk by inaction. My risk is already nearly 0, so I don't really care to minimize it further anyway, but by vaccinating I'm taking on a lot of uncertainty (in personal risk, effectiveness of the vaccine over time, transmission reduction, etc), so it's impossible to assess properly with these unknowns. I would much rather just get COVID. You don't see an issue with that, right?

Your risk of a negative outcome from a vaccine is lower than your risk from infection, and they're both very low. The negative outcome from a vaccine is very low for everyone, while the risk of a negative outcome from COVID is low for you.

> I would much rather just get COVID. You don't see an issue with that, right?

Of course I see an issue with it. The vaccine causes your body to produce a subset of proteins from the COVID genome. A controlled, inert subset. You would rather your body produce whole live viruses that mutate, evolve and want to kill you. That makes no sense.

I agree vaccines aren't a panacea for transmission, but I know they're less risky than whole live viruses shooting out of you lol.

I'd argue that's dark ages thinking but even they were pro-vaccine because they were anti getting sick. Shouldn't really be controversial in this the year of our lord 2021.

Deciding not to get vaccinated massively increases your risk of transmitting the virus to others. An unvaccinated person is far more likely to get the virus, and then if they get it, they are far more likely to transmit it. Any way you parse it, vaccination is preferable to infection. The worst case with vaccination is that you get a breakthrough infection. But that's far less risky than getting infected in the first…

You are far less likely to get infected at all if you're fully vaccinated, and people who aren't infected can't transmit the virus.

If you do get a breakthrough infection, the time window during which you're infectious is far shorter.[1]

There's more and more data now on how much vaccination lowers transmission. For example, a recent study found that vaccinated people who caught the virus are 40-50% less likely to pass it on to their family members than unvaccinated people are.[2]

> I would rather have SARS-COV-2 injected into my arm personally.

This is insane.

Literally every vaccine in the United States comes with a liability waiver. Since 1986, you've had to sue the US Federal Government. https://en.wikipedia.org/wiki/National_Childhood_Vaccine_Inj...

I think you are missing some facts here. COVID vaccines are not on the list of eligible vaccines for that program. You also can't sue the relevant govt departments for the COVID vaccine. This article does a nice job of going into the nuances https://www.cnbc.com/2020/12/16/covid-vaccine-side-effects-c... Also, a better link than a wikipedia article: https://www.cdc.gov/vaccinesafety/ensuringsafety/history/ind...

I'm confused which facts you think that I'm missing.

>That it went faster doesn't mean it's less safe

No, but it does the mean the long term risk are not defined as well. What if, for example, this causes reproductive harm, or some harm to the offspring? I personally believe this is very unlikely, but it's too early to know at the moment. Or, what if the ADE risk is real, and vaccinated individuals aren't able to combat variants as effectively, perhaps even reacting worse to reinfection? It's simply too early to evaluate so many risk here. On the other hand, I can be pretty sure COVID won't cause birth defects, given that no coronaviruses do.

>hospitalization rates are 15-200X higher in the unvaccinated and death rates are 8-87X higher

Well, of course - there's a lot more unvaccinated people and cases, what else would you expect? And I'm not at risk of being hospitalized anyway, so I still see no reason to try and mitigate that risk. My time would be better spent ensuring my car is operating safely, or a million other things that could decrease my chance of harm more substantially.

Regardless, taking the vaccine is pointless beyond self-preservation if it doesn't reduce spread, and at the moment that's unknown, and complicated by the fact that some 'variants' seem to side-step the vaccine. Sitting on the side lines and waiting for more data seems reasonable to me.

That's why we have 32 years of study on mRNA vaccines are almost 50 years of study on viral vector vaccines.

> What if, for example, this causes reproductive harm, or some harm to the offspring?

You have no basis for that. What if it causes some people to grow a third arm? A fourth testicle? Again, we've studied the vaccine and know that it does not affect the germ line.

> Or, what if the ADE risk is real, and vaccinated individuals aren't able to combat variants as effectively, perhaps even reacting worse to reinfection?

The data that I linked you shows otherwise?

> It's simply too early to evaluate so many risk here. On the other hand, I can be pretty sure COVID won't cause birth defects, given that no coronaviruses do.

No mRNA vaccine has caused that either lol, nor has any viral vector vaccine. So why would it start now? It's as likely to do that as it is to grow in a bonus nut. [1] Note that the CDC does not specifically cover my bonus nut theory, so who knows? I'll keep an eye out for it tho.

"There is currently no evidence that any vaccines, including COVID-19 vaccines, cause fertility problems in women or men." [1]

I mean why would they? A viral vector vaccine is a virus, just like COVID (well, more specifically, an adenovirus) which doesn't infect germ cells.

> Well, of course - there's a lot more unvaccinated people and cases, what else would you expect?

That's up to 200X higher per capita in the un-vaccinated population vs the vaccinated population.

> And I'm not at risk of being hospitalized anyway, so I still see no reason to try and mitigate that risk.

Everyone is, at different rates, and your rate is strictly higher than after vaccination.

> Regardless, taking the vaccine is pointless beyond self-preservation if it doesn't reduce spread, and at the moment that's unknown, and complicated by the fact that some 'variants' seem to side-step the vaccine. Sitting on the side lines and waiting for more data seems reasonable to me.

The infections from variants are still hundreds of times less severe in the vaccinated.

>You are far less likely to get infected at all if you're fully vaccinated

This is what I'm asking about, transmission. The data on this is woefully limited however.

Here's another Fauci quote:

    So far, the available Covid-19 vaccines have not been judged primarily on their ability to prevent transmission – though this is now being evaluated as a secondary endpoint for many of them. Instead, their efficacy was assessed by whether they could prevent symptoms from developing. “This means that we set our targets kind of pragmatically,” says Danny Altmann, professor of immunology at Imperial College London.

    …

    There isn’t yet any conclusive evidence that the Pfizer-BioNTech vaccine can prevent people from being infected with the coronavirus – and therefore halt its spread. But there are some early signs that it might.
When these were being released, no one knew it's effects on transmission, yet the sentiment was that they certainly did, and questioning this brought about frustration.

>There's more and more data

There's also data building to the contrary. Take a look at Israel's number of cases vs vaccination status, for example. We're not at a stage where data is conclusive either way, and in that case I'm fine with waiting things out.

For example, this is what you're study says:

>The mRNA vaccines are highly effective at preventing symptomatic and severe COVID-19 associated with B.1.617.2 infection

This is not about reducing SARS-COV-2 transmission, but symptomatic COVID. These mistakes lead to misinformation spreading.

Further, this is all your second study concludes:

   Among index patients, those who had been vaccinated were likely to be less severely symptomatic2 and might have been less infectious than those who were unvaccinated.
As I'm sure you know, correlation does not imply causation, it's possible that vaccinated individuals were simply practicing better viral hygiene (especially given that they were vaccinated back in Jan/Feb, when there was less social pressure and more risk).

>That's why we have 32 years of study on mRNA vaccines

Yes, in which they were largely viewed as non-viable and a shelfed idea at least in part due to issues like ADE. The research here was not extremely active, nor was it done on humans to the extent it is now.

>You have no basis for that.

Correct, but I have no basis to believe that some unseen risk is not present too. Given that I'm not personally at risk for COVID, I think there's wisdom in waiting a couple years (at least) to see how it unfolds. And there is a basis for ADE fears, which you ignored in favor of joking about growing a spontaneous third testicle.

>do you not think anyone has had a child since they were vaccinated?

One child would not imply it's impossible for _some_ child to have a defect.

>The data that I linked you shows otherwise?

Can you point me to where this was? The 'data' is still very immature regardless. I'm sure I could source data that comes to the opposite conclusion. It's important to view these things in aggregate, not lean on the studies you agree with. Right now, I'm finding studies that disagree often, so I think waiting for the data to mature a bit is reasonable assuming I'm not harming anyone by doing so.

>The infections from variants are still hundreds of times less severe in the vaccinated

You missed my point here - the point is that they can still get infected, not that they aren't expressing symptoms as severely.

...

Birth defects were just an example, like I said I view it as unlikely. The point is that there's a potential for unseen risk here. You've devolved into being a bit rude now, and I found your lack of skepticism tiring anyway. The data is all over the map currently, yet you seem rigid in your position - that's bad practice. You keep making arguments about the vaccines being effective at symptom reduction, but that's never been the point I'm trying to engage, since I agree with that and there is pretty conclusive data there. I will say that you can find data to the contrary (see Israel's recent stats), but mostly I'm saying that a) as someone who's already _not_at_risk_, there's arguably no net benefit to society in me taking the vaccine, so long as transmission rate reduction is largely an unknown (and even in that case, I'd prefer natural immunity) and b) there's a possibility of unforeseen and unwanted side effects / repercussions due to the vaccine - this is true despite you belittling this idea.

I'm not at risk, so I don't care about minimizing it or how effective it is. There is a possibility I may be a host to transmit COVID to people at risk though, so I care about that. As of now, natural immunity looks much more enticing than vaccination for someone like me. Why are you so opposed to this? I won't be hospitalized, so you don't have to worry about me, and I presumably will spread it similarly to how vaccinated individuals will.

There are still a lot of people trying to tout the "do-nothing" approach to CoVID-19. It's been obvious for more than a year that it's possible to eliminate the virus entirely and then reopen society with very few restrictions. This approach saves lives, gives people the ability to live their lives normally, and is better for the economy. China, Australia, New Zealand and a few other countries have demonstrated this.…

Less than a month ago, 40% of the Australian population was under a stay-at-home order: https://www.bbc.com/news/world-australia-57845163 The Australian military is being used to intimidate dissenters (eg. anti-lockdown protests) and enforce lockdown: https://www.bbc.com/news/world-australia-58021718 Australia is absolutely not an example of success, it has deteriorated into a police state.

Australia has been living normally for most of the last year and a half, unlike virtually the rest of the developed world. If you deal decisively with outbreaks before they become serious, you can eliminate them and get back to your normal life more quickly.
