My little one has had 3 different lots of vaccinations (2, 4 and 6 month old ones) and each time has been quite unwell for close to a week. I brought it up with the nurse (i had them done at local council sessions) at the following sessions and they really didn't care. They did not report it as adverse reactions. Their lack of concern has given me greater doubt that issues are followed up appropriately.
That's because asking a "health" professional about the negatives or side effects of vaccination is like asking a butcher about the pros of being vegan. If you want to go against the recommended and never tested as safe vaccination schedule you're better off doing your own research and making an informed decision based upon facts rather than asking your nurse's or GP's **opinion** (because that is all it is). I encourage you to look up information about CYP450 enzyme in infants and how that might affect vaccination.
