They are approving JnJ as we speak. Now that the data is out officially it’s a formality. Nothing to stop it now but if you believe it won’t be approved I will gladly take that bet.
Just my 2 cents: listing out all of the possible ways that the vaccine rollout could fail is being overly pessimistic. That’s my opinion of course so it can’t be right or wrong. Only listing negative “facts” is by definition being pessimistic. You do you. Nothing you have said so far changes my belief that the vaccines were highly effective against hospitalization and death. Some of those things you listed will never be known. There can always be a new variant or immunity could fade over time. Should the plan be to continue as we are today forever just in case?
My simple solution is this, once everyone has access to the vaccine they start rolling back covid restrictions. Anyone who has been vaccinated but feels the vaccines are not effective can choose to stay home, avoid crowds, and wear a mask still. Nobody will be forced to stop doing those things. There’s no reason to ask people to continue as if nothing has changed once the vaccine is rolled out.
Where did I say it won't be approved? It almost certainly will be approved. And I have been saying that for weeks/months.
But again, honesty, truthfulness and facts are important.
There is a difference between "It's already approved" and "it's likely going to get approved."
And saying things are "unknown" is neither optimistic nor pessimistic. I've cited tons of "positive" and "optimistic" facts.
Saying, "we don't know what percentage will be required for herd immunity" is neither optimistic nor pessimistic.
If someone said, "we won't get to herd immunity until we reach 100% vaccination until 2022!" -- Then am I being an optimist or pessimist when I say, "we don't know that."
And finally -- Your simple solution -- We are ALREADY rolling back Covid restrictions. We've been rolling them back for a while. The question is, when do we ELIMINATE Covid restrictions, when we do allow maskless large gatherings?
And there, every single health expert is in agreement -- We need to wait until we have herd immunity.
You may have your "opinion" that all of the experts are wrong. But I'll side with the experts.
I get you're in a hurry. But if we can prevent 50,000+ deaths (mostly among non-vaccinated people, but including a few vaccinated people) by wearing masks for an extra 4-6 weeks.... Then I'll fully support mandatory mask wearing for an extra 4-6 weeks.
And if we can prevent millions of 2022-2025 deaths by wearing masks for an extra 4-6 weeks in 2021... even more so, I'm all for it.
