OP: why are you reluctant for you to have the jab?
You clearly don't mind others having the jab.
It's always this way with vaccinations.
Having a vaccine, or making the choice to have your child vaccinated, means taking a small risk that something will go wrong. No wonder people hesitate.
However, most of us also look at what could go wrong if most of the population is not vaccinated against common illnesses. The risks from measles, TB and so on are worse, in aggregate, and to the individual.
So most of us go ahead, and if enough of us get vaccinated we get herd immunity and those diseases start to die out. It happened with smallpox. We were well on the way to that with measles and then Andrew Wakefield put out his scaremongering inaccurate research, and as a result some children have died or been left with lifelong health problems from measles, which is a tragedy.
Meanwhile, there's always one little group who know about herd immunity and decide they're going to have the best of both worlds. They or their children won't be vaccinated, but as most other people will, the risk is negligible and they haven't taken any risk with the vaccine. Win win! The fact that this is selfish appears not to register, or at any rate matter to them. Also, of course, if their numbers grow, there's no herd immunity, and we're back to where we started.
