I do know a lot of people who avoided the whooping cough vaccine not because of 'principle' but because of severe reactions to the 5-in-1 vaccine that contains the whooping cough vaccine now-two of my boys had severe reactions to the 5-in-1 we are talking long term failure to thrive problems here which meant they were extremely susceptible to dangerous illnesses during that time. I have not yet given the 5-in-1 vaccine with this baby and am looking into private seperate vaccines, I could not risk his health and despite having the same allergies as my other boys he has not had the same health issues at all. Other babies have had fits and cysts on the brain due to this vaccine-this 5-in-1 vaccine isn't licenced in the vast majority of countries and I believe the UK government should scrap it and go back to the DtaP version (diptheria, tetanus, whooping cough) which is used in 99% of countries, the reasons they introduced the 5-in-1 for are no longer valid; the DtaP no longer contains mercury and there is now a seperate inactivated polio injection that didn't exist 5 or 6 years ago. The dtaP is a lot safer and i feel they'd get a lot more uptake of it xx
N.B. there have been serious whooping cough outbreaks even when the vaccination rate is really high, I don't know how effective the newer versions are but the older whooping cough vaccine was known to be not that effective, my sister had it and still contracted a severe form of whooping cough
