Agree that you’ve looked and looked again at this stuff and that’s why it’s showing you more.
Have a go at altering your algorithm next time you’re on SM. So if it shows you any anti-vax stuff say you’re not interested, if it gives you that option and definitely don’t watch it.
Instead, search for more positive things, things that you’re interested in and things that will help you day to day.
I have a go at searching for new things about once a month, especially on Insta and by and large my feed is quite positive. If you keep watching videos which are causing you to question research, then it’s just going to end in a big negative loop for you.
I’m old enough to remember life before MMR.
There were kids in schools that were viewed as “problems” and written off. From the schools I attended I wouldn’t say there was a modern epidemic of ASD, just that more get assessed and some get the support they need.
I have an eyesight problem due to having Measles and I’ve helped to look after a boy that was left blind, severely deaf and brain damaged through having the Measles, bedding 24 hour care for years.
I’m not sure why the focus is always on “there’s only been one death” when there’s the potential for life altering conditions for even previously healthy children.
