Don't get me wrong, I am a staunch pro vaxxer, but I have learnt, getting into debates on here, that there are many people who would vax for certain things and not others, whooping cough without the tetanus for example.
I don't think it is a good thing - but I would far rather see someone vaxxed against a few diseases than none at all. And at the moment, there is no law saying that everyone has to be vaxxed, so we need to encourage those who want to selectively vax to at least get some.
If you put them all together, they will just turn around and say, well, I would have done a) b) c) but now I will do none. ANd that doesn't help anyone.
I personally think the more the better, less needles etc. But I still think that people should be able to get them separately.
