That's not how science works. You can't separate the good effects from the bad effects of vaccines.
Nobody is suggesting that the smallpox and polio vaccines didn't work to minimize these diseases. The question is at what cost, and is the cost sufficient to try for a vaccine against sniffles.
We know that things like mercury and aluminum in the body have downsides. We know now that there are bacteria as small as viruses that cannot be filtered out of vaccines. We know via mouse experiments that giving vaccines to very young mice can eliminate any defense against later infection, rather than enhance it. What we need now is a much better view of what the risks are before we start bombarding new--borns with lots of vaccines.
You can't point to one accepted fact like vaccines eliminated smallpox and project that onto the question of what the cost/risk is for vaccines and how that compares to the risk for getting a vaccine against sniffles.
There have been vaccine shortages because some makers ran afoul of government quality rules. Let's hope the next vaccine you get wasn't made the day before such a shutdown.
“That’s not how science works. You can’t separate the good effects from the bad effects of vaccines. “
Oh yes it is. The effectiveness of vaccinations in protecting against communicable disease is not even a subject of debate. The means and methods are subject to change as improvements in those means and methods are made - and the supporting data becomes available.
It’s the BS from the anti-vaccine crazies that is the only subject of debate. Yes, there are effects for everything you do, medically, but ultimately, with the state of vaccine research today, you are left with the statistics of illness and vaccination as your guide, until we get better data. The statistics say that you are putting your kids at risk of severe illness if you ignore the vaccination guidelines.
As vaccine research advances, guidelines change - this is a strength of science, not a weakness as some of the crazies will have you believe.
Anyway THAT is how science works with regards to vaccines.
