Bloomberg News reports on a study published in JAMA Pediatrics on the attitudes of parents towards HPV vaccines and the reasons parents may choose not to vaccinate their children. The study analyzed 55 studies from 2009 to determine reasons people choose to vaccinate or not to vaccinate. The study found that although the vaccine is recommended for both boys and girls, 54% of girls received one dose of the vaccine, while only 21% of boys received at least one dose. Additionally, only 33% of girls received all three shots that comprise the full vaccination, and only 6.8% of boys did. Researchers found that the low rates of vaccination are connected to “parental concern that getting vaccinated for HPV may increase teenagers’ sexual activity.” Many doctors feel that the decision to vaccinate is “out of their control” and the parents are acting as barriers to appropriate vaccination.
