ตอบคำถามข้อนี้โดยนำคำถาม-ตอบของ CDC มาให้ดูนะครับ
1.Who should get HPV vaccine?
-Cervarix and Gardasil are licensed, safe, and effective for females ages 9 through 26 years. CDC recommends that all girls who are 11 or 12 years old get the 3 doses (shots) of either brand of HPV vaccine to protect against cervical cancer and precancer. Gardasil also protects against most genital warts. Girls and young women ages 13 through 26 should get all 3 doses of an HPV vaccine if they have not received all doses yet.
-Gardasil is also licensed, safe, and effective for males ages 9 through 26 years. Boys and young men may choose to get this vaccine to prevent genital warts.
-People who have already had sexual contact before getting all 3 doses of an HPV vaccine might still benefit if they were not infected before vaccination with the HPV types included in the vaccine they received. The best way to be sure that a person gets the most benefit from HPV vaccination is to complete all three doses before sexual activity begins.
2.Why aren’t HPV vaccines recommended for people older than 26?
Both vaccines were studied in thousands of people from 9 through 26 years old and found to be safe and effective for these ages. The FDA will consider licensing HPV vaccines for other ages if new studies show that this would also be safe and effective.
