How to scientifically dismantle the four main anti – vaccine arguments

One of the most recent posts in the “Health is Global” blog, written by Adelaida Sarukhan tries to dismantle some misleading believes that create some doubts on people about whether or not to vaccinate their children.

9, vacunes

As Sarukhan says, “The anti-vaccine movement gained momentum more than a decade ago with the publication of a study (with 12 children) showing an association between the MMR vaccine and autism. Since then, the paper has been retracted (and its senior author discredited) because of data manipulation, and a dozen of large-scale studies (a recent one included more than 90.000 children) have conclusively shown that there is no link between the vaccine and autism. Nevertheless, the anti-vaxxers persist with a series of arguments for which there is no scientific evidence but that generate hesitancy among a worrying increase in the number of affluent and educated people who, due to the success of vaccination itself, have forgotten that not so long ago children were dying from diseases such as diphtheria, polio or measles.”

She then goes on to give some scientific evidence against some of those ill-advised arguments:

1. “Vaccines contain toxic substances such as aluminium and mercury”

2. “Too many vaccines can overload the child’s immune system”

3. “Natural immunity is better”

4. “Vaccines cause autoimmune disorders, asthma and allergies”

In the full post here you can read her convincing arguments to make your case in favour of vaccines. You can also find more about vaccines in the “Science uncovered” sections of Ellipse #82 here and #87 here (in both cases, go to page 6!).
