I think it's just the speed at which it has happened though. Most children born in developed countries today receive a slew of vaccines which will provide immunity to catching those diseases for decades. It's discouraging that we're looking at shot no. 4 for the mRNA covid vaccines within a year and a half, and despite even that, infection rates are still very strong.

Because corona viruses are a different kind. There have been no vaccines against them so far and we saw how strongly they mutate. Still, the 3-shot regime seems to be very effective against severe disease. They probably deliver as much protection as possible unless you have a vaccine which targets exactly the strain you are fighting. So it will be interesting how the omicron-specific vaccines will do, if they do get used for larger campaigns.

Thanks for the breaks analogy, it’s one I intend on using when talking to people I. The real world. It’s a good one given how basically everyone has either dealt with or understands this basic yet essential car maintenance issue and the nature of the appropriate response.

Car brake dust is an extremely potent carcinogen, take care when dealing with them.

At least they don't make them from asbestos anymore.

My dad tells me about taking shop class in high school, and they'd be sanding down asbestos brake pads with an angle grinder to remove the high spots to prevent glazing. No masks of course.

OEM might not be asbestos but aftermarket asbestos containing pad can be bought. Who knows that the material does that's in them today?

I'm generally surprised by what I was exposed to at shop class, not necessarily asbestos but machines that could absolutely wreck a body let loose by a bunch of haphazard children. Blinding lights, kids sticking like 4 inches of iron into a hydraulic cutting machine and hitting go. A girl cut her finger off on a bandsaw.
