Scientists point out and condemn the problem of the 'wrong paper' announced by the vaccination opposition



Although vaccination is an effective means of preventing infectious diseases, in recent years in the vaccination of the vaccine has been working the activation of the anti-vaccine faction such as the cause of the disease, in 2019 the World Health Organization (WHO) is vaccine repellent epidemic As a major and global threat to health . In 2018, a person from such an anti-vaccine group published a paper saying that “inoculation of cervical cancer vaccine causes infertility”, but many problems have been pointed out by scientists.

Bogus Paper Claims HPV Vaccine Causes Infertility, Scientists Shred It to Pieces

HPV vaccine (cervical cancer vaccine) that prevents infection of certain human papillomaviruses related to the occurrence of cervical cancer, etc. is an effective means to prevent cervical cancer, and the American Center for Disease Control and Prevention also that it is safe and effective vaccine has been recognized . Side effects have been investigated by scientists for many years, and no adverse effects such as infertility have been confirmed.

However, many anti-vaccines still think that “the birthrate in the United States has been declining because of the HPV vaccine”. One of them is Gayle DeLong , an anti-vaccine activist and associate professor of economics and finance at the City of New York City Baruch's Gicklin Business School.

As Associate Professor of Economics and Finance, Delong is not a medical expert, but in 2011 he published a paper claiming the link between autism and vaccination in the Journal of Toxicology and Environmental Health Part A Announced. The content was inconsistent with the results of previous research, and was criticized by autism experts.



Delong said in 2014 that he had breast cancer despite having few cancer families in his family and living a healthy life. It brought up the thing due to the stress 'and claims . This was also blamed by experts .

As a masterpiece, Delong published in 2018 is a paper claiming that HPV vaccines cause infertility . In this paper published in the “Journal of Toxicology and Environmental Health Part A” as in the 2011 paper, Delong said that in 2006, HPV vaccination was introduced in the United States. It claims to be the cause of the decline in fertility rates for older American women.



A variety of problems have been pointed out by medical researchers such as Ayako Shibata from Yodogawa Christian Hospital and Yuki Kataoka from Hyogo Prefectural Amagasaki General Medical Center .

Shibata et al. Pointed out that HPV vaccination is recommended for teenagers, and if HPV vaccines actually cause infertility, it will take more than a few years to take effect. Therefore, DeLong points out that the claim that “the introduction of HPV vaccine in 2006 has caused a decline in the birthrate of women aged 25 to 29 in the United States since 2007” is inappropriate. In Australia and European countries where HPV vaccination has already been carried out at a high rate, there has been no noticeable decline in the birth rate.

From these points, experts such as Shibata et al. Tried to shift the age of having children in the life plan because the birth control rate in the United States became easier to use various contraceptive methods. He claims that this may be due to a rise in thinking. DeLong's study focused only on the decline in fertility rate and did not consider the rise in contraceptive rate.



In addition, DeLong's study mentions that it is analyzing the data of 8 million women collected in the National Health and Nutrition Examination Survey conducted in the United States. Only surveyed 700 women as sample sizes. Moreover, over 400 people were not vaccinated with the HPV vaccine, and there was a difference in the size of the sample groups.

DeLong examined the rate of pregnancy in the HPV vaccinated and non-vaccinated groups, but the HPV vaccinated group is likely to have a university degree, and these women have children. The age of birth tends to be late. The study was conducted only on women aged 25 to 29, so the survey was conducted when the female with a degree was under the average age of having the first child.

In addition, “ Journal of Toxicology and Environmental Health ” that published DeLong's paper twice is a peer-reviewed magazine, but it is a “suspicious magazine” that has posted genuinely suspected papers by anti-vaccines from before Therefore, even if DeLong sends a paper to another magazine, it is considered unlikely to be published.
