Smallpox didn't just go away. It came year after year for 2,300 years. Sometimes it killed millions at a time, sometimes tens of millions. In its last 100 years, smallpox killed an estimated 500 million human beings. It didn't kill everyone on Earth, but it wiped out huge swaths of people. Polio didn't kill everyone on Earth, but year after year outbreaks left many people dead and many more crippled for life; most of them children. It absolutely terrorized parents for generation after generation. You think a parent who's lost a child to polio cared that other kids lived? You think someone who is crippled for life is thanking their lucky stars?
If the plumber and the food inspector and the trash man were all that were needed to eradicate disease, we wouldn't have any diseases anymore. Yet here we are, still dealing with diseases, including new ones like SARS-CoV-2 that's killing over 130,000 Americans. What we need is a constant herd immunity to help contain outbreaks. The quickest and least painful way to achieve herd immunity is with safe and effective vaccines that are widely deployed.
Each of these diseases was brought to its knees at very different times. All of those times just happen to be directly after widespread vaccine use. You really think every single disease we vaccinate against just decided to surrender at that exact moment for no other reason? Smallpox decided after 2,300 years to just disappear from the entire Earth for no reason, unrelated to the massive worldwide effort to vaccinate everyone against it?
What an amazing coincidence! That after 2,300 years killing hundreds of millions of human beings, smallpox vanished from the face of the Earth after a 9 year smallpox eradication effort using mass vaccination!
Some vaccines are very effective.
Some diseases are very lethal or debilitating.
Some vaccines have a low rate of adverse reaction.
Some diseases are highly contagious.
You are applying a broad brush, pretending all vaccines are highly effective, all vaccines have low side effects, and that all diseases are lethal and unavoidable without a vaccine.
Unfortunately, even though your reasoning uses a vaccine with a low rate of adverse side effects when convenient as an example, uses other and more more effective vaccine as an example when convenient, and then uses very deadly diseases when convenient, the reality is you don’t get to pick and choose the combination. Your argument falls apart somewhat with the flu vaccine and near entirely with a mandatory requirement for HPV (behavioral based illness that is entirely avoidable) vaccine. The argument you make is sort of like this: cars are perfect and will cure all our transportation issues because they are safe (Volvo), efficient (Leaf), perform well and are practical (Mercedes AMG SUV), are cheap (Yaris), use up little space (Smart) and can tow or carry a lot (F350). Now, show me the car that has all these attributes in one? That’s what you’re doing with vaccines and arguing that they are all perfect and a fix to everything.
Then when someone points out that vaccines while beneficial also have their down sides and limitations, you argue they are anti-vaccine.
Absurd and a waste of time. Argue with someone that can understand your colorful charts.
