Anti-vaxxers are self absorbed narcissists and I pay them as much mind as flat earthers. Fair enough, if you choose that for yourself, but don't inflict it on your children. Herd immunity has been proven successfully to work. We have an immune system, and yes I realise, bacteria and viruses are constantly mutating, if our body has been challenged with a form of, say, measles and has the antibodies in place it's in a far better position to deal with a mutated form of the virus in the worse case scenario than someone who has no basic immunity to it.
Our immune systems have to be challenged, we can't vaccinate against every pathogen, but there needs to be a common sense approach. These vaccinations are in place for a purpose; polio, rubella, mumps etc are illnesses which caused many issues/deaths historically for the very young and immune compromised, why wouldn't you want your child to be protected from that? Why would you want them to suffer unnecessarily for something that could have been prevented or at the very least reduced in severity significantly?
Conversely, people not choosing to vaccinate is not solely responsible for resurgence in virtually eradicated diseases, things like over prescribing antibiotics, antibiotics in animal feeds etc have essentially forced these bugs to mutate, what is much scarier is that a fair few of these bugs are now resistant to drugs commonly used to treat them in the past i.e. MRSA, VRE, MDRTB, with very few new treatments forthcoming
