Except that no, it isn't.
How many US vaccines are given in a normal year? There are under 4 million kids born each year in the US. What is the normal vaccine schedule - DTAP, Polio, Hep B, RV, Hep A, MMR, throw in 2 more that I probably don't remember. So say 32 million vaccines given to kids each year (ignoring that a lot of kids don't get all of them). Now for the sake of disproving your position, add in all of the Rona vaccines given and we'll say that is 150 million. So say 200 million people vaccinated this year to add in some other instances like flu shots and be extremely conservative, so 200 million is our denominator. And though anti-vaxxers would say this number is exponentially low, let's use the 6 J&J issues as the numerator. So 6 out of 200 million. Pretty fucking small, right? Statistically insignificant, right? Is anyone thinking rationally going to change the current vaccine program because of that? Hell no.
Okay, so now look at cop deaths compared to interactions. We'll use the 1,000 as your numerator (which is being generous, as a good number of those are not unjustified, but we'll use it anyway). But what is your denominator? How many interactions do US citizens have with cops each year? I went to a Hornets game Saturday night. Walked right by 3 cops directing traffic going in. So did 5,000 other people. Walked by them on the way out, too. So that's 30,000 interactions just for that event. Nobody got killed or maimed. Work in Uptown Charlotte with the other 130,000 people? Then you'll walk by at least 2 cops on the way in, the way out, the way to lunch, the way back from lunch. Nobody dies. That's close to a million interactions just for that miniscule portion of the population for 1 day. Drive by a cop sitting in a speed trap who doesn't move. How many cars? Thousands per hour? That is every day. Now extrapolate that across the country for 330 million people. Every day. What is your denominator? 10 billion? 100 billion? Whatever it is, it is an enormous fucking number. So how does your 1,000 compare?
So yes, 6 out of 200 million is a minute number that is statistically irrelevant. But so is 1,000 out of tens or hundreds of billions.
There is some truth to both groups' positions. Anti-vaxxers would say their numerator is much larger than cop deaths, because there are not cell phones capturing their instances. And it clearly sucks for the people involved in both factually correct situations. But both groups' claims are statistically insignificant to their overall respective situations and shouldn't be the focus of much attention relative to other national issues. But they can't see that, and have both skewed all related conversation so irrationally that neither can or should be taken seriously.
