Here’s a revised version of the text, incorporating verification and prioritizing authoritative sources.
The human papillomavirus (HPV) vaccine is a safe and effective tool for preventing HPV-related cancers and maintaining public health,health officials emphasize.
“The HPV vaccine has been used worldwide for years and is both safe and effective,” a health expert explained. It protects both boys and girls from HPV infection,which can lead to several types of cancer,including cervical,anal,and oropharyngeal cancers [1].
the vaccine is most effective when administered before the onset of sexual activity, as the immune response is strongest at this stage. Therefore, it is typically administered during the eighth grade, around ages 11-12 [2]. The Centers for Disease Control and Prevention (CDC) recommends routine HPV vaccination for adolescents,starting at age 11 or 12,and continuing through age 26 [2].
