The anti-vaccination movement is a term loosely referring to the fringe groups that advocate parents should deny their children vaccines. These groups vary in size, however the spreading of misinformation is most often always involving the relation between autism and vaccination. This began in 1998 when the flawed study was conducted by a British medical journal, but was later retracted a council that regulates Britain's doctors and ruled that the study's author acted dishonestly and unethically. In recent years the anti-vaccine movement has gained momentum and whereas one and FOUR parents believe there is a causal link believe vaccines and autism based on a flawed study and all of the leading health organizations including the CDC and the NIH say that there is absolutely no link, yet still there are websites and people spreading misinformation.. Preventing a children from inoculation is child abuse; at the very least these parents should be warned and/or heavily encouraged to vaccinate their kids, and at these parents should be shamed for endangering everyone. Children who are not vaccinated are a danger because in order for a population to shield itself effectively, 90 to 95 percent of its children need to be inoculated. There have already been outbreaks in communities, ranging from measles to small pox because of the recent rise of parents refusing to inoculate their children. While these groups who openly denounce vaccines have every right to speak, there should be an even greater emphasis on parents to verify whether or not a claim is scientifically backed.
