The point of having a vaccine is to stop the spread of the disease. For that to work, we may need to mandate that people are vaccinated, and I am ok with that.

No, sorry. My body. My choice.

So long as you don't mind being 'sent to Coventry' by the rest of us.

We only need to vaccinate high risk people. Under 50 crowd does not need a vaccination.

I'd rather not get sick and risk dying, even if I'm under 50. Thank you very much. And more importantly, even if the risk of death is low for me, I can still transmit it to high risk people.

I'm not saying you shouldn't have the option... but there's plenty of us that understand how risk works.

Why would we need that? I think a lot of people will get immunity the natural way, even now a lot of people are having covid w/o any symptoms at all, and they will have immunity.

> Why would we need that? Because best case 0.1% death rate times best case 50% required for herd immunity times 7.8 billion people is 3.9 million dead people. And that's pretty bad.

Herd immunity is only going to be around 10 to 20% because of previous cross-reactivity with common cold viruses.

Sweden Italy and New Zealand have already hit herd immunity. They're done with the virus and didn't have 50 percent.

And before you post that they have a few cases recently... understand herd immunity doesn't mean the virus is gone...it just means the virus has nowhere to jump to... so there will always be a smattering of cases.

This is false, immunity is strong and long-lasting. The news is trying to sell papers. A vaccine is also an attenuated version of the virus so if becoming immune from the virus doesn't last long it won't last long from a vaccine.

Most of your reply isn’t really correct. > A vaccine is also an attenuated version of the virus so if becoming immune from the virus doesn't last long it won't last long from a vaccine. A vaccine can be an attenuated virus, or a piece of mRNA or DNA, or a distinctive viral protein. Which type of vaccine you use+the adjuvants that go with it can result in very different immune responses and efficacy over time. > This…

Most of your reply to my reply is incorrect.

>mRNA is part of a pathway that creates a protein that is on the virus which the immune system reacts to.

>Please post your source saying that people can be re-infected.

The only reason people are testing positive again after having Covid and healing from it is because the test is very poor at distinguishing between various coronaviruses, the vast majority of which are harmless and sometimes cause the common cold. There is a big false positive rate as a result.

Could you link to studies that support this point of view, if you have any? What are your sources?

Why would we need to vaccine absolutely everyone ? isn't herd immunity a thing?

Herd immunity is a thing, but as I heard one scientist describe it: It's not a question of achieving herd immunity or not, it's a question of how. Mass vaccination also leads to herd immunity, it's achieved by creating immunity in individuals through a vaccine instead of by contracting the virus naturally.

I'm a bit surprised to see so much opposition to vaccination here on HN, I would have thought that this would be a very pro-science and pro-vaccination crowd. As far as my understanding goes, herd immunity is not a real alternative to vaccinations. Herd immunity means that a very large percentage of the population, spread evenly across every community, would have to be infected and recover, another commenter cited a…

Not opposed to vaccines. Opposed to rushed, poorly tested, politicized pharmaceuticals. Poorly tested drugs have severe consequences. Just because you WANT a miracle, doesn't mean the first person offering one will actually help.

Hear hear!

Not yet, and it is possible that immunity does not last long enough for herd immunity to ever happen. It's too early to tell.

This is false immunity is strong and long-lasting otherwise they wouldn't be sinking billions into a vaccine which operates the same way that infectious immunity operates.

I think you misread an article. I saw one mention that 20% decline the infection rate. That's entirely different than herd immunity. I don't see any article saying that the mentioned countries have hit herd immunity. Especially New Zealand seems questionable, they've gone to a full lockdown, not for herd immunity.
