A VACCINATED ELDER IN GERMANY TODAY IS ONLY 46% LESS LIKELY OF DYING OF COVID COMPARED TO ONE YEAR AGO

thread with data and explanations

TL;DR: the vaccine reduced risk of dying conditional of catching the virus, but the virus spread and this year you're more likely to catch it
Another data point: the average unvaccinated adult German (18-59yo) is THREE TIMES more likely of dying of COVID today than one year ago. Even though the 2/3 of the population that's vaccinated should protect them.

Because there are more cases → higher risk of catching it
Herd immunity works in the measure the herd isn't infected.

If the vaccine meant that the vaccinated cannot get sick or transmit the virus, and if the virus hadn't spread wildly, then herd immunity would protect the community.

But it's not what's happening.
If you're not vaccinated yet, be careful.
Things are not getting better, if your country still has lot of cases.

And if you're vaccinated, know that it's not a silver bullet. A vaccinated elder in Germany today is only 46% less likely of dying of COVID compared to one year ago.
Let me repeat.

A VACCINATED ELDER IN GERMANY TODAY IS ONLY 46% LESS LIKELY OF DYING OF COVID COMPARED TO ONE YEAR AGO

That's not what most think, and it's important to dispel the false sense of security.
Source for my claim above: the calculations in the screenshot below, based on the data at the link in the tweet below, and numbers of deaths yesterday

I'd love to repeat the calculations above for longer periods, such as the whole November. Still, I don't think that the point will change much: yes, the vaccine protects us, but this is significantly offset by increased spread.
Conclusion: it's imperative that we all keep using those non-majorly-restrictive measures such as masks & ventilation, because how much the virus spreads matters a lot, even if there's a vaccine and even if it'll become endemic
Of course, the above applies to Germany and, I guess, other countries with high spread.

It doesn’t apply to countries that managed to control spread better.

ENGAGING & RETAINING TALENT

Next week, I'll hold a free one-hour online seminar on employee engagement and retention.

Register using the link below
(more info in the thread)

us02web.zoom.us/meeting/regist…
In the one hour, I will cover two principles and three practical actions that will help with engaging and retaining your workforce.

It's not a full coverage of everything there's to know about the topic, but it will be practical enough to give you some concrete results.
In the Q&A at the end, you will also have an opportunity to ask me about any specific problems you are encountering on the topic.

If you cannot make it live, I will share an excerpt of the session on my mailing list (Luca-dellanna.com/newsletter)

PRE-MORTEMS

- Imagine your key employee just handed you his resignation letter. Why would it be?

- Imagine your team just called you in the middle of the night. Why would it be?

- Imagine your key client just passed to a competitor. Why would it be?

Luca-dellanna.com/pre-mortems
POST-mortems are asked after the problem hurt you. "Why did the project fail, and what can we do better next time?"

PRE-mortems are asked before the problem occurs. "Let's imagine the project failed. What could have happened?"

With pre-mortems, you have time to react.
Pre-mortems don't have to be just negative. They can be positive too, such as: "Let's imagine that the project was wildly successful, well above our expectations. What would we have done today that made it succeed?

More indication that the vaccinated are more similarly contagious as the unvaccinated than thought (but for shorter time and, of course, less likely to be hospitalized and die)
On the one hand, similar viral load doesn’t necessarily mean similar contagiousness, and household studies have the property that rate of viral spread matters less than in other spaces.

On the other hand, one more indication that vaccines aren’t silver bullets.

Not the same. Once a group is driven out of voting it won’t have representation.
They are elected representatives. You want to override someone’s representatives. Who’s the fascist?

Fascists are denied by reacting strongly to any violation of rights / constitution, regardless of the color of the shirt of the one committing it. This is one of such.

Italy seems to be planning not to accept COVID tests anymore for its Green Pass.

Terrible, because most jobs require a Green Pass.
I’m against any restriction that doesn’t focus on risk.

IMHO legislation should be agnostic as to how I’m reducing risk, whether it’s through vaccines or test + masks.
Also, I’m slightly afraid of the restrictions that can be accepted by a population of 80% of vaccinated who’s suggested, “restrict the unvaccinated more or lockdown again”.

Hence the importance to talk in terms of risk, not vaccine.
