No, I actually do believe that there are some parents who put in the minimum required effort and sometimes a lot less. There are also some parents with good intentions who simply can't cope with the job and don't get the help that they need. A public health campaign needs to be designed around these people, not the informed and motivated parents.

Giving a baby an all-in-one jab means it is a lot likelier that the children of those parents will get their immunisation than if they were required to come back on multiple occasions a little later in life. Unfortunately if that is the only option on offer then anyone who might want a different immunisation schedule has to fight to get what they want.
