a) 1
b) 2
c) 3
d) 4

Answer 1

The HPV vaccine, including Gardasil and Cervarix, is recommended to be given in a series of 3 shots before an individual becomes sexually active. It targets high-risk HPV strains but does not cover all HPV types.

Step-by-step explanation:

The HPV vaccine is an important preventive measure against certain strains of the Human Papillomavirus (HPV), particularly those that cause cervical cancer and genital warts. For the vaccine to be effective, it must be administered before an individual becomes sexually active. The current HPV vaccines available, such as Gardasil® and Cervarix®, are designed to protect against some of the most dangerous HPV strains. A series of 3 shots is typically recommended for optimal protection, although a 2-dose schedule may be used for individuals who start the vaccination series before their 15th birthday. It's important to note that while these vaccines target the most high-risk HPV types, they do not protect against all of the more than 200 types of HPV.
