It is becoming abundantly clear that the material costs of vaccines now considerably exceed even their theoretical benefits:
Birth rates in the United States have recently fallen. Birth rates per 1000 females aged 25–29 fell from 118 in 2007 to 105 in 2015. One factor may involve the vaccination against the human papillomavirus (HPV). Shortly after the vaccine was licensed, several reports of recipients experiencing primary ovarian failure emerged. This study analyzed information gathered in National Health and Nutrition Examination Survey, which represented 8 million 25-to-29-year-old women residing in the United States between 2007 and 2014. Approximately 60{f82a6d9b5e5cff01d97267394322fca158507b75156f51cfa613d94c4c7ae29a} of women who did not receive the HPV vaccine had been pregnant at least once, whereas only 35{f82a6d9b5e5cff01d97267394322fca158507b75156f51cfa613d94c4c7ae29a} of women who were exposed to the vaccine had conceived. For married women, 75{f82a6d9b5e5cff01d97267394322fca158507b75156f51cfa613d94c4c7ae29a} who did not receive the shot were found to conceive, while only 50{f82a6d9b5e5cff01d97267394322fca158507b75156f51cfa613d94c4c7ae29a} who received the vaccine had ever been pregnant. Using logistic regression to analyze the data, the probability of having been pregnant was estimated for females who received an HPV vaccine compared with females who did not receive the shot. Results suggest that females who received the HPV shot were less likely to have ever been pregnant than women in the same age group who did not receive the shot.
All of this to try to reduce the incidence of a very widespread virus that is so non-lethal that it annually kills one out of every 5,575 women who have it. I wonder how many young women will be willing to be vaccinated against HPV once they have a better understanding of how it will lower their chance of ever having children.
