The science facts about autism and vaccines
Lancet published a paper by Dr. Andrew Wakefield, a dramatic study that found a connection between autism and vaccines
The Study Had Some Problems:
1. Not based on statistics
2. No control group
3. It relied on people's memories
4. Made vague conclusions that weren't statistically valid
A study of 500 children no connection was found.
A study of 10.000 children still found no connection.
A study from Denmark of 537.000 found no connection.
Lancet released a statement refuting the original findings. "They had conducted invasive investigations on the children without obtaining the necessary ethical clearances... picked and chose data that suited their case: they falsified facts".
A review of 3 I studies covering more than 10.000.000 children. Also found no connection.
A review of 27 cohort studies, 17 case control studies, 6 self-controlled case series studies, 5 time series trials, 2 ecological studies, I case cross-over trial covering over 14.700.000 children
VACCINE VILIFICATION SURVIVES
1/4 U.S. parents believe some vaccines use autisr in healthy children.
1.8% of parents opt out of vaccines for religious or philosophical reasons.
COMMON VACCINE MYTHS
"Vaccines are ridden with toxic chemicals that can harm children"
Thimerosal, the chemical being referenced, does contain mercury. However, thimerosal has been removed from scheduled vaccines and only resides in the seasonal flu vaccine.
"The decision to | not vaccinate my child affects my child"
Un-vaccinated children who contract a disease can infect infants yet to be inoculated, the small percentage of people whose vaccines did not take, and people with compromised immune systems.
"Receiving too many vaccines at once can override a baby's immune system"
Baby’s immune systems are strong enough to defend from the day to day viruses and bacteria with which they come in contact; they can also handle the vaccines. Remember, vaccines use deactivated viruses in their ingredients.
"Drug companies just do it to make profits"
According to the WHO. estimated 2013 global revenues for all vaccines is around $24 billion, which only accounts for approximately 2 - 3% of the total pharmaceuticals market.
