How effective is HPV vaccine? Are there any side effects?
Transcript
HPV vaccine is a prophylactic vaccine to prevent cervical cancer as well as other HPV-related cancers or diseases. In Hong Kong, HPV-16, 18, 31, 33, 45, 52, 58 accounted for about 90% of cases of cervical cancer. All the above seven genotypes are included in the 9-valent HPV vaccine.
HPV vaccines have been used worldwide for many years. After extensive examinations of scientific evidence and information on adverse reactions following HPV vaccination, the World Health Organization and overseas health authorities have concluded that HPV vaccines are safe and effective, and there is no evidence that HPV vaccination will cause serious side effects. The Department of Health will closely monitor the report of adverse events after immunisation following the implementation of the programme.
HPV vaccines are generally safe. Most students do not have serious reactions after receiving HPV vaccination. Common side effects are similar to those from other vaccinations, such as:
- Mild and short-lasting side effects, including headache, dizziness, nausea and fatigue.
- Soreness, redness or swelling at the injection site.
