Question

Why does the Gardasil-9 vaccine only prevent certain types of HPV and not all?

Answer 1

Ans) Gardasil-9: Vaccination given:

- Girls (9 to 26) and Boys (9 to 15)
- 3 doses
- HPV types 16, 18, 31, 33, 45, 52, and 58 which cause cancer and HPV types 6 or 11 which cause genital warts.

Gardasil-9 vaccine prevents certain types of HPV and not all as-

- HPV types associated with genital warts are different than types associated with cancer.

- Most genital HPV infections clear on their own.

- FDA and the Centers for Disease Control and Prevention (CDC) considered adverse side effects related to Gardasil immunization that have been reported to the Vaccine Adverse Events Reporting System since the vaccine was licensed (16–18).

- The rates of adverse side effects in the safety review were consistent with what was seen in safety studies carried out before the vaccine was approved and were similar to those seen with other vaccines.

- However, a higher proportion of syncope (fainting) and venous thrombolic events (blood clots) were seen with Gardasil than are usually seen with other vaccines.
