The entire concept behind vaccines is not that it saves everyone, not that they are perfect, not that they don't cause problems themselves, but they reduce the total mortality of the population.
This requirement that they are absolutely safe is, frankly, ridiculous. I always remember my doctor telling me that ALL medicine is the same - there is ALWAYS a cost.
It's scary, taking a risk by saying yes to any medicine, because it may may kill you and it certainly will change you. But statistically your chances are better if you take it.
Honestly, it seems to me that anti-vaxers are just afraid of making that decision. I sometimes think we would be better off with a Chinese government who would just tell you what to do and be done with all this debate.
Yup
People who claim vaccines are unsafe because there are potential side effects have obviously never paid any attention to any medical procedure, test or medication they've ever had.
Every single medication, test and procedure has a set of risks involved, and every time they are licenced that risk is assessed compared to what it is doing.
Even the gloves doctors used to wear had a high chance of causing an allergic reaction in a very small percentage of the population.
Paracetamol can damage your liver.
Ibuprofen can cause issues with the stomach lining (so you take another medication to prevent that, which in turn has it's own lesser issues).
When you go for a blood test you run a risk from the damage the needle does, and if you have too many blood tests (or donate regularly) it can cause an issue with accessing the veins in the future.
A chest x-ray can cause miscarriages, especially early on in pregnant women.
I won't go into the list of "scary" side effects listed on the packet of anti histamine tablets I've got in front of me.
That's before any of the medications and procedures that are actively damaging and risky but are significantly less so than not doing anything.
And the really stupid thing is that a lot of the medical stuff with risks that people panic about are far lower than the risks from other things they do daily without a thought, it's just that anything involving side effects or deaths from medical related things is reported centrally, recorded and made public so that researchers, doctors and patients can be aware of them and hopefully safer/better ways to do them can be found.
Or they'll say how unsafe vaccines are then go and take a deworming paste intended for horses and not be at all worried about the fact they're literally pooping a layer of skin from their guts out because they've taken a huge dose far in excess of the safe human level.
