Worth reading again. The #Swisscheese model is a guide for our strategy to quell #covid19 & other pandemics (#monkeypox?)
No single intervention is perfect.
Each layer may have holes.
But the pile will provide.
Pick well your pile!

Novembre 2020:
"It’s important to understand that a vaccine, on its own, won’t be enough to rapidly extinguish a pandemic as pernicious as Covid-19.

#SwissCheese thought;

"The pandemic cannot be stopped through just one intervention, because even vaccines are imperfect"

5/"It helps to think of these in terms of layers of defense, with each layer providing a barrier that isn’t fully impervious, like slices of Swiss cheese in a stack."

I had said recently
#layersofprotection

While reading again I prefer the words of the article
#layersofdefense

6/The “Swiss cheese model” is a classic way to conceptualize dealing with a hazard that involves a mixture of human, technological and natural elements.

7/The British psychologist James Reason introduced the model more than three decades ago to discuss failures in complex systems such as nuclear power, commercial aviation and medical care.

8/ The “Swiss cheese model” applied to #covid19 by te Australian virologist Ian MacKay, became an online sensation among Covid-19 watchers. It showed particles of the SARS-CoV-2 virus passing through layers of Swiss cheese, shrinking in numbers as they negotiated the holes

9/Thanks to the pile of #layersofdefense.s the #swisscheesemodel described the possibility to achieve 0 , ZERO, #ZeroCovid arriving to the individuals.

10/"These various approaches—whether individual or collective,—are not mutually exclusive"". In fact, they often have complementary strengths and weaknesses. ""And they work best in combination."

11/ Of course, some layers—such as testing, masking and a good vaccine—are more effective than others, such as sanitizing surfaces. These are the Swiss cheese slices with fewer or smaller holes.

12/ But no single intervention is enough. Even after a vaccine is widely available, other interventions will still be needed, at least for a while.

13/The Swiss cheese model can thus show us a path forward for sensible, science-based policies at the local and national level.

14/ First, it’s clear that, in order to stop the spread of the virus and deflect the course of the pandemic, we need to think in terms of deploying enough layers of Swiss cheese. In any setting, it’s more important to choose several interventions than any particular one.

15/ But to succeed, a person, family, business or nation must adopt several different measures, not just one or two.

16/ the Swiss cheese model also helps to explain how and why different countries have succeeded using different approaches.

17/ Finally, the Swiss cheese model highlights how we might avoid relying on some of the more disruptive and controversial Covid-fighting measures, such as stay-at-home orders and school closures.

18/If several layers of defense are already in place and holding strong, additional layers might be unnecessary to close gaps.

19/ The country needs a fresh start in how we discuss and solve this crisis. We must realize that we all bear responsibility for implementing multiple interventions and that doing so will actually free us from other, more serious constraints on our social and economic lives.

20/ In any epidemic, a basic task of leaders is to help people understand what is happening and to model good behavior themselves. Garnering public trust can be seen as its own layer of defense and not just as a way to boost the efficacy of other interventions.

21/ we’ll need to see public education campaigns that reach into every corner of American society. ...With effective leadership at every level, starting with President-elect Biden, we can work together to build real defenses against Covid-19, layer by layer.
