Step-by-step explanation:
The full course of the Human Papillomavirus (HPV) vaccine consists of 2 injections for both girls and boys. The vaccine is recommended to be given between the ages of 11 and 12. However, young people who do not get vaccinated at those ages can still receive the vaccine up to age 21 for males and age 26 for females. The main purpose of the vaccine is to protect against developing HPV-related cancers later in life.
