Sixty-three women and girls who reported side effects from cervical cancer vaccines sued the government and drugmakers on Wednesday as a sharp divide remained over the risks the medicine poses.

The plaintiffs, ranging in age from 15 to 22, filed suits in district courts in Tokyo, Nagoya, Osaka and Fukuoka, demanding compensation of at least ¥15 million each.

The plaintiffs say they experienced a wide range of health problems including headaches, fatigue and mobility impairment after receiving the human papillomavirus (HPV) vaccines between 2010 and 2013.
