Rebecca Kerr, who died of a rare form of leukaemia in January 2011, is one of the teenagers whose parents believe she died as a result of the HPV vaccine.
It prevents infection by the sexually transmitted human papilloma virus which is behind the majority of cervical cancer cases.
Last night her father David, 53, a gas engineer from Essex, said his daughter became unwell within weeks of receiving the second dose of the vaccine just before her 13th birthday.
The teenager, who was studying for her GCSEs at Francis Bardsley School for Girls in Romford, died of lymphoblastic lymphoma a year later.
Mr Kerr said: “It was rare that she ever got poorly and yet she got ill so quickly after having the vaccine. There is no doubt in our minds that there is a link, although the doctors maintain they do not know why children get leukaemia.”
