In the fall of 2020, a crucial initiative was launched by the American Cancer Society aimed at correcting widespread misconceptions surrounding the HPV vaccine and boosting vaccination rates. This effort was prompted by alarming research revealing a 71 percent decline in doctor visits among 7- to 17-year-olds during the pandemic, which understandably led to a drop in vaccination rates. However, the decline in HPV vaccination was evident even before the pandemic, with a staggering 70 percent decrease observed from April 2019 to April 2020. By May 2020, the rates had plummeted an additional 50 percent.
While the COVID-19 pandemic undeniably contributed to this decline, there may be other factors at play. Dr. Emily Johnson, a professor at the University of Missouri School of Journalism, conducted a recent study analyzing over 6,500 social media posts related to the HPV vaccine. Alarmingly, nearly 40 percent of these posts amplified fears regarding the vaccine, and the prevalence of such posts has been increasing over time.
With HPV vaccination refusal rates reaching as high as 27 percent in certain regions and persistent myths surrounding the vaccine, it is crucial that parents are not exposed to misleading social media posts that present the vaccine negatively. The HPV vaccine has been available for 15 years, with over 120 million doses administered. It underwent rigorous testing prior to its release and has demonstrated nearly 100 percent effectiveness in preventing cervical cell abnormalities in girls, as well as 90 percent effectiveness against four types of HPV associated with genital warts and penile lesions.
Since 2016, the HPV vaccine has been credited with reducing infection rates among teenage girls by 64 percent. Research indicates that achieving an 80 percent vaccination rate could prevent an additional 92 percent of HPV-related cancers. This is a remarkable and lifesaving vaccine, yet misconceptions have deterred many parents from vaccinating their children at a crucial time.
Dr. Johnson’s research underscores the risk posed by social media, where “anti-vaxxers” can disseminate misinformation and gain traction among uninformed parents. Her earlier work identified social media as a breeding ground for these narratives, and her latest study highlights the dangers of fear-based posts. “Fear-inducing posts tend to trend more than those that don’t,” Dr. Johnson noted in a recent interview.
The algorithms governing social media platforms exacerbate this issue. Posts that generate high engagement—whether positive or negative—are shown to more users, allowing misinformation to spread rapidly among those who may already harbor fears. This creates an echo chamber of misleading information, disconnected from scientific fact, which can also extend to perceptions of the COVID-19 vaccine.
Combating this misinformation is a challenging task. Vaccine-related fears are often deeply ingrained. However, socially aware users can counteract negative posts by sharing scientifically backed information. Engaging in discussions carefully and promoting dialogue with healthcare professionals and credible organizations like the CDC and the American Academy of Pediatrics can help dispel myths. Additionally, users should be vigilant in recognizing harmful posts and reporting misinformation to limit its visibility.
Importantly, it’s essential for parents to educate their children on how to find reliable information and develop critical thinking skills when confronted with unverified claims. While it may be too late for some adults, fostering responsible social media use in the next generation can lead to a more informed public.
