An urgent investigation was under way on Tuesday after a 14-year-old school girl collapsed and died after being vaccinated against cervical cancer.

The girl, who was named as Natalie Morton, died on Monday shortly after being injected with the Cervarix vaccine at the Blue Coat CofE school in Coventry.

The vaccine, which is made by pharmaceutical giant GlaxoSmithKline, is being administered to schoolgirls as part of a national vaccination programme to protect against the disease.

Health authorities immediately isolated the suspect batch of vaccine which protects against Human Papillomavirus (HPV), a sexually-transmitted virus which is the primary cause of cervical cancer.

“The incident happened shortly after the girl had received her HPV vaccine in the school,” said Dr. Caron Grainger, joint head of public health for the National Health Service (NHS) in Coventry and Coventry City Council.
