US Disease Control and Prevention Centers (CDC) are planning a broad study that will consider the possible relationship between vaccines and autism, reported two sources in Reuters that are aware of the subject, despite extensive scientific research that has denied or not found any relationship between the two.

It is not clear whether US Minister of Health Robert F. Kennedy Junior, who has long been promoting anti -vaccination views, is involved in the planned CDC study, nor has it been clarified how it will happen. The CDCs and the Ministry of Health were not readily available for a comment.

The CDC decision was made amid one of the largest measles epidemics that the US has experienced in the last ten years, with more than 150 cases and two deaths in Texas and New Mexico. The epidemic appears to have been staged by a decrease in vaccination rate in US areas where parents are convinced that vaccines are doing more harm than good to their children.

Kennedy, The responsibilities of which the CDC supervision also has long been doubts about the safety of the triple vaccine about measles, mumps and red (MMR). At the cabinet meeting last week, Kennedy initially downgraded the news that a school age died of measles in Texas – the first such death in a decade – calling such a common phenomenon and failing to mention it.

On the weekend, Kennedy published an opinion article on Fox News that promoted the role of vaccination, but also told parents that vaccination was their personal choice and urged them to consult their doctor.

Autism diagnoses have increased significantly in the US after 2000which intensifies citizens’ concerns. Many researchers attribute this increase to the fact that medical examinations are now more widespread, but also expanded the range of behaviors considered to be indicative of the particular condition. However, some disseminate the idea that the vaccines are responsible, citing a 1990s study, which has now been denied by British researcher Andrew Wakefield. That study linked the increase in autism cases using the triple child vaccine.

The causes of autism are unclear. No study has found a relationship between autism and vaccines or other drugs. Scientists speculate that the neurological characteristics of autism occur during the period when the fetal brain develops in the uterus. Studies link autism with mother’s health problems during pregnancy or with complications during childbirth.

In his speech in Congress this week, US President Donald Trump referred to the increase in autism cases in children. “Well, we will find what is happening and no one is better than Bobby (the Minister of Health) and his associates to do so,” he said.
