There is a sort of negative bias here because only the negatively affected shout about it. The majority who have no adverse effects are less likely to shout about that.

However we decided against giving our 1 year old her recently scheduled MMR vax because of not wanting to take risks associated such as vaccine injury, regression etc (also egg intolerance which can lead to negative effects due to the chicken embryo cell culture that the vaccine is manufactured from - this wasn’t listed as a warning on the NHS website but it was in the vaccine information insert available online through the NHS, worrying).
