たしかに今接種しても意味があまりなワクチンも厚生労働省は任意接種を推奨しているものもあります。例えば、破傷風のワクチンも任意接種のワクチンの１つですが、破傷風が日本で最後に確認されたのは今から25年も前のことになります。このように「なぜ強く接種を勧められるのだろうか」と不思議に思うワクチンも数多くあります。しかし、たくさんの方が心配している自閉症の発症確率が上がるようなことはないとJournal of Pediatricsという論文誌に掲載された研究発表がありました。
Today, I will be talking about the following research paper (There is a link to the paper at the end of the texts) --> DeStefano, F., Price, C.S. and Weintraub, E.S. (2014). Increasing Exposure to Antibody-Stimulating Proteins and Polysaccharides in Vaccines Is Not Associated with Risk of Autism. Pediatria Polska, 89(5), pp.T31–T38.
Have you heard of anyone saying antibody-stimulating Proteins and polysaccharides
in vaccines can cause autism when they are injected to little kids younger than 2yrs old? Those are often included in MMR vaccinations and flu vaccinations.
It is true that in Japan, there are many vaccinations that are no longer thought to be needed but Ministry of Health, Labour and Welfare is still strongly recommending to get one. For example, the case of tetanus has been last reported in 1995 in Japan, but it is still strongly recommended vaccination in Japan. I sometimes do wonder if they ever reconsider the vaccination requirements based on the number of cases that has been reported. However, getting autism by those vaccinations is a different story. The research published in Journal of Pediatrics has recently reported that vaccinations including antibody-stimulating proteins and polysaccharides do not cause autism, and the association was not seen.
They tested 256 children with autism and 752 control group (healthy children) with same age and grew up in relatively the same way to compare the vaccination history. Researchers did not find any evidence supporting the claim. There are some pediatricians who recommend not to get certain vaccinations because of this reason, but since there is no strong evidence telling us that autism can be caused by vaccinations, I still do recommend the vaccinations that pediatricians recommend you. However, there are some cases that children have allergy against those vaccinations, or some other medical conditions that might not be good to get vaccinations. In those cases, I really do thing it is important to consult with GP!
