To be clear, the study suggests 80% immunity after COVID for those UNDER 65. Over 65, immunity drops to 47%.

Immunity didn’t drop 6 months out. So that’s good. On the downside, this doesn’t include re-infection with variants.

What does this all mean?
It’s hard to compare directly to vaccines but on the surface, it looks like vaccines provide better immunity than natural infection, especially the mRNA vaccines. Maybe Novavax too.
It may appear natural immunity beats out AstraZeneca and J&J, but the effectiveness of vaccines is inclusive of ALL ages, not just under 65. So those vaccines are likely at least on par. (To say nothing of protection against severe infection, death and variants).
The study didn’t really identify if the people who got infected a second time got less sick. The study design didn’t really allow for that.
What’s the real take home:

This study suggests if you’ve had COVID, you can still get reinfected and therefore should get the vaccine (any vaccine) to boost your immunity. This is ESPECIALLY true if you’re over 65.

Also, the rate of blood clots in the general population (regardless of vaccine or COVID) is greater than 30 cases in 5 million.

This kind of stuff will come up as we vaccinate basically the whole world. It’s important to pause and look at the data.
This will happen again and again.

A bunch of people who got vaccinated get X. Can the vaccine cause X?

Pause and look at the data. Do people who get the vaccine get X more than unvaccinated people? That’s the key question.

In this case, it appears the answer is no.
The question answered by the article is a separate one. Do people who get the vaccine get X less than people who get COVID?

Also a good question, but I think it’s a secondary one. If vaccinated people don’t get clots any more than unvaccinated people, then there’s no issue.

I suspect these ages are going to change quickly over the coming weeks.

If you’re in Saskatchewan and you or someone close to you is over 80 and hasn’t been vaccinated yet, make sure they get booked in!
If you have an elderly neighbour, knock on their door (step back to keep distance) and ask if they know they can be vaccinated. If you have friends with older parents / grandparents, make sure they know too.
When you have a newborn, everyone always asks you how they’re sleeping. “Hey, how are you? Awww... he’s so cute. How’s he sleeping?” Like EVERYBODY asks this.

That’s what we should be like with vaccinations. “Hey, how are you? Did you get vaccinated?”

The summary in this link is a well done explanation of their reasoning here. I can clarify more if people would like, but this is a real change in vaccine strategy if all the provinces adopt.
Ok, here’s the deal:

When the Pfizer trials were first released, people noticed something pretty quickly. For the first couple weeks, people who got vaccine (blue) got COVID at about the same rate as placebo (red). This makes sense. It takes a bit for the vaccine to work.
But after that, the vaccine group stopped getting COVID while placebo kept going. So there was a clear benefit BEFORE the second dose (around day 21).

One thing to remember:

If you take a vaccine that has, say, 90-95% efficacy but are surrounded by people with virus, you are actually LESS safe than if you are unvaccinated but are surrounded by people who have all taken that vaccine.

That’s herd immunity.
The idea here is that taking a vaccine is only in part about individual risk/benefit. The other part is whether you contribute to the “herd”. The vaccinated people who protect those susceptible.

Which leads to the obvious question: who are these susceptible people?
Some of them are people who may, for whatever reason, choose not to get vaccinated. And you could argue that that is an individual risk they take. Why should I be concerned? And that’s a fair argument.

But there are other categories of susceptible people.

This is an awesome question. (Incoming big thread!)

The vaccine studies looked for symptoms of COVID. So it was easy to say from the trials that the vaccines prevented symptoms & hospitalizations. They didn’t directly test for asymptomatic spread. So we couldn’t say for sure. 1/
Now, if you’re not getting sick, and your immune system is primed to attack the asshole protein & destroy the virus quickly, logically you’d expect to spread the virus ‘less’ or ‘not at all’. But until you have evidence of that, you can’t say for sure. 2/
The Moderna trials tested everyone at the time of their 2nd dose. People who got the vaccine were less likely to have asymptomatic COVID. So that’s some evidence the vaccines also prevent getting asymptomatic COVID, not just symptoms. 3/
