heart attacks don't spread in enclosed spaces

No, but they do spread via memetic infection of cultural norms that direct us as individuals to adopt unhealthy lifestyles.

which is certainly a problem worth solving, but it's still a different issue than a highly infectious disease that can be spread on elevators buses

I hate it when I catch an avoidable memetic infection from somebody a couple seats behind me on a plane because of the relaxed memetic infection rules.

Who cares? Everyone has been vaccinated at this point unless you're so deluded from reality you missed the vaccination campaigns in every country on Earth.

A few years ago I got the 'rona and recovered. A few weeks later I went to doctor who got me blood test to confirm antibodies. He wrote letter stating I had it, I fully recovered, and the vaccines are not recommended. On a lark I got another antibody blood test recently and the markers are as strong as the first blood test - no waning.

I'm not talking about a fear budget, I'm talking about actual money. In 20 years we had SARS, MERS, ebola, H1N1, and then SARS 2. It makes no sense to shut down a program that keeps an eye on potential pandemics.
