After coming across concerns over severe side-effects of the cervical cancer vaccine, health regulators have decided to launch an investigation into the safety of the vaccine. The human papilloma virus jab is offered to very girl at secondary school to stay prevented from the disease.

However, many experts have to say that the program should not be affected by the investigation as it plays an essential role in helping prevention of the most common cancer among the under-35s.

The European Medicines Agency (EMA) has now made the mind to conduct an official review to see possible links to two rare conditions -- complex regional pain syndrome and postural orthostatic tachycardia syndrome (PoTS). The former is a chronic pain condition affecting the limbs and the latter causes abnormal heart rate.

Campaigners for years are calling for an investigation into the drug’s side-effects as several families complained that their daughters’ health deteriorated after taking the jab. Healthy teenagers have suffered fits, extreme tiredness after taking the vaccine. As per official figures, 8,228 cases have been reported for suspected side-effects since the HPV vaccination program started in 2008.

The EMA made it clear in a statement on Tuesday that the benefits of HPV vaccines outweigh their risks. It added that the review process will not impact the program so as to keep using them as a safety measure against the disease.

“Reports of these conditions in young women who have received an HPV vaccine have been previously considered during routine safety monitoring but a causal link between them and the vaccines was not established”, said the regulator.
