Those serious side effects are allergic reactions and occur in less than 1% of vaccinations.
Would your rather eradicate horrific, fatal diseases? Or worry about an adverse effect that occurs one in a million.
The argument against big drug companies and pushing drugs for profit is irrelevant in relation vaccines. In certain pharmaceutical markets, yes, but not vaccines. A drug company may give a doctor incentives to push a certain drug but that doesn't relate to MMR, tetanus, hep, hpv shots or anything else your baby would get when born.
In the UK, the MMR vaccine was the subject of controversy after publication of a 1998 paper by Andrew Wakefield et al. reporting a study of twelve children who had bowel symptoms along with autism or other disorders, including cases where onset was believed by the parents to be soon after administration of MMR vaccine.[33] In 2010, Wakefield's research was found by the General Medical Council to have been "dishonest",[34] and The Lancet fully retracted the original paper.[35] The research was declared fraudulent in 2011 by the British Medical Journal.[36] Several subsequent peer-reviewed studies have failed to show any association between the vaccine and autism.[37]
The Centers for Disease Control and Prevention,[38] the Institute of Medicine of the National Academy of Sciences,[39] the UK National Health Service[40] and the Cochrane Library review[17] have all concluded that there is no evidence of a link between the MMR vaccine and autism.
Administering the vaccines in three separate doses does not reduce the chance of adverse effects, and it increases the opportunity for infection by the two diseases not immunized against first.[37][41] Health experts have criticized media reporting of the MMR-autism controversy for triggering a decline in vaccination rates.[42] Before publication of Wakefield's findings, the inoculation rate for MMR in the UK was 92%; after publication, the rate dropped to below 80%. In 1998, there were 56 measles cases in the UK; by 2008, there were 1348 cases, with 2 confirmed deaths.[43]
In Japan, the MMR vaccination has been discontinued, with single vaccines being used for each disease. Rates of autism diagnosis have continued to increase, showing no correlation with the change.[44]
