Aims: Human papilloma virus (HPV) is 1 of the most common sexually transmitted infection responsible for different types of cancer: cervical, penile, vulvar, anal and oropharyngeal. It can affect both males and females. Our aim was to enrich the knowledge on the safety profiles of HPV vaccines in the male population. Methods: We reviewed all the reports of adverse events following immunization (AEFI) present in the US Vaccine Adverse Event Reporting System from 1 January 2006 to 30 September 2018. Statistical data mining was performed using the reporting odds ratio with 95% confidence interval in order to detect disproportionality in reporting. Results: A total of 5493 reports of AEFI were retrieved. The events most reported and that proportionally occurred more frequently with HPV vaccines than with others in males were: syncope (n = 701, reporting odds ratio = 2.85, 95% confidence interval [1.41–5.76p), loss of consciousness (n = 425, 2.79 [1.36–5.72]) and fall (n = 272, 3.54 [2.00–6.26]). Conclusion: Most of the AEFIs were already reported in premarketing clinical trials and acknowledged for the corresponding vaccines. A disproportionate reporting was found for some of these events including syncope. The HPV vaccines are generally well tolerated in males, although limitations own of spontaneous reporting should be considered.

Abstract

Aims: Human papilloma virus (HPV) is 1 of the most common sexually transmitted infection responsible for different types of cancer: cervical, penile, vulvar, anal and oropharyngeal. It can affect both males and females. Our aim was to enrich the knowledge on the safety profiles of HPV vaccines in the male population. Methods: We reviewed all the reports of adverse events following immunization (AEFI) present in the US Vaccine Adverse Event Reporting System from 1 January 2006 to 30 September 2018. Statistical data mining was performed using the reporting odds ratio with 95% confidence interval in order to detect disproportionality in reporting. Results: A total of 5493 reports of AEFI were retrieved. The events most reported and that proportionally occurred more frequently with HPV vaccines than with others in males were: syncope (n = 701, reporting odds ratio = 2.85, 95% confidence interval [1.41–5.76p), loss of consciousness (n = 425, 2.79 [1.36–5.72]) and fall (n = 272, 3.54 [2.00–6.26]). Conclusion: Most of the AEFIs were already reported in premarketing clinical trials and acknowledged for the corresponding vaccines. A disproportionate reporting was found for some of these events including syncope. The HPV vaccines are generally well tolerated in males, although limitations own of spontaneous reporting should be considered.
