Look I will bite on the slight chance that @grabbit is not a troll and genuine,
I was an anti vaxxer at one point. It was a private doctor who sat down and had the time to discuss my concerns (which obviously I paid for his time to do) who persuaded me to vaccinate and at the time I could afford to do this and catch my child up. I will be forever grateful that by whatever means, even me paying... someone helped me to understand the risks I was taking with my child who I love more than anything and how stupid I was being to think I was saving them from anything by simply not vaccinating. I've been on both sides, I've probably read the same stuff, spoken to the same people. My child is now vaccinated beyond any other child their age who used the NHS schedule.
I have friends who have delayed vaccines and one who I do agree with her decision - possibly that child is one of the higher risk children to vaccinate based on his current health conditions
I completely do understand someone being scared of vaccinating based on a few very tragic examples of children who seemed triggered by a vaccine
I think it may have been the doctor I used though who pointed out to me that yes, it's possible that vaccines harm a small proportion of children who are predisposed to reacting badly for reasons we don't yet know... but all of those children if they react so badly to the vaccine which holds a tiny amount.... just imagine what would happen to those children if they actually contracted the disease itself. Do you really think if a child has a severe reaction to the vaccine that if they caught the actual disease they'd be in the catagory of those for whom the disease may be a "mild childhood illness"? They aren't the children for whom it would be a mild childhood illness, they are the kids who at best would be left permanently disabled and may end up dead!!!
The other children for whom it would be a mild childhood illness- will have no problem with a vaccine
The reason someone may be unlikely to catch the diseases is that herd immunity prevents disease from circulating, we need it. Especially the children who have other health conditions that clearly indicate they are at risk.
Diseases aren't static - what may have often been a mild childhood illness when everyone used to get it - isn't, when few people get it - they have to evolve to survive and can be far more serious years later because of this or when someone's immune system is more mature as they are older it can be a much more serious disease to catch and need to fight
If not enough people vaccinate for herd immunity then as a whole - even those vaccinated are at risk, because having a vaccine does not mean that you won't catch the disease. You will have a much higher chance of not catching it - but all of our bodies are different- one person may produce a higher level of protection than another in their body after a vaccine or the disease, some people don't actually become immune at all for whatever reason and in some it wears off sooner. Herd immunity is not a private choice to make really... enough people make it and we have the disease circulating and spreading more often harming more people- particularly those children who would potentially be vaccine damaged, who if they contract the disease - suffer long lasting effects of disability or even death. The only reason @grabbit finds her children safe is because of those who make the choice (bar any obvious health conditions) to vaccinate their kids and contribute to herd immunity. If this drops though... supposing they are a child who would possibly react badly to a vaccine (which we know based on the large numbers who vaccinate is a very very small proportion) ... they will also react very very very badly to the disease, it's very likely they will die or be permanently severely disabled!!! By deciding herd immunity isn't her responsibility for her kids (as I naively once did when entrenched in pseudoscience) she is putting them at even greater risk of being affected badly.
It's not really a choice in my mind anymore. It's actually making her own children at greater risk. I'm glad I learned this before I learned it the hard way as I would never have forgiven myself.
