A recent study by Prem et al., published in BMC Medicine, has shed light on the benefits of a reduced-dose human papillomavirus (HPV) vaccination program compared to the standard two-dose schedule. The World Health Organization (WHO) designated cervical cancer as a global public health concern in 2020, making HPV vaccination a crucial measure in reducing cervical cancer cases worldwide. However, high costs, logistical challenges, and limited vaccine supplies have led to disparities in vaccine distribution, particularly in low-income and middle-income countries (LMICs).
The situation worsened with the onset of the COVID-19 pandemic, resulting in a significant decline in HPV vaccine coverage for girls aged 9 to 14, reaching a mere 12% in 2021. To address this issue, Prem et al. studied the potential efficacy and duration of protection provided by a one-dose HPV vaccination regimen versus the standard two-dose schedule in 188 countries.
The findings of the study highlighted several advantages of a reduced-dose HPV vaccination program, particularly in LMICs. Firstly, it could significantly reduce the costs associated with vaccination programs. Secondly, it simplified the implementation of vaccination campaigns. Lastly, it helped mitigate the challenges related to vaccine supplies.
Implementing a one-dose HPV vaccination schedule has the potential to narrow the gap in vaccination coverage between high-income countries (HICs) and LMICs, making significant progress towards the goal of eradicating cervical cancer globally.
Furthermore, the cost-effectiveness analysis of the 9-valent HPV vaccine revealed that the cost threshold for the second dose was lower than the established minimum pricing by the United Nations Children’s Fund Supply Division (UNICEF). This indicates the need for further adjustments in the minimum pricing of HPV vaccines to ensure the cost-effectiveness of the two-dose vaccination program in low-income countries (LICs).
While the initial investment for a reduced-dose HPV vaccination program may be high, reducing the unit cost of the vaccine could help LICs overcome financial barriers and sustain HPV vaccine initiatives.
In conclusion, the findings of this study provide valuable insights for stakeholders involved in expanding HPV vaccination programs. However, it is crucial to emphasize the importance of political commitment and public awareness to overcome barriers hindering vaccine uptake.
Additionally, ongoing research on HPV vaccines should guide decision-making processes, including the impact of a reduced-dose vaccination schedule on a nation’s healthcare budget. Affordability remains a pertinent concern, particularly in countries with competing healthcare priorities.
As new data on HPV vaccination continues to emerge, researchers have the opportunity to explore potential differences in the efficacy of both vaccination schedules. This will facilitate the gradual expansion of HPV vaccination initiatives while accommodating the specific healthcare budget constraints of each country.
