The Medicines and Healthcare products Regulatory Agency (MHRA) collects reports of suspected side effects to vaccines and medicines via the Yellow Card Scheme. It is important to note that a report of a suspected side effect does not necessarily mean the vaccine or medicine was the cause of the reported event, and coincidental illness can also be a factor. Such reports remain under continual review by the MHRA in order to detect possible new risks.
The MHRA has received 198 United Kingdom spontaneous suspected adverse reaction reports temporally-associated with human papillomavirus (HPV) vaccine between 1 January 2016 and 9 October 2016. Table 1 below provides a breakdown of these reports by month.
Number of reports
October to date (9 October 2016)
More than 9 million doses of HPV vaccine have been given in the UK, with close to 90% of eligible teenagers vaccinated. As with all vaccines, safety remains under continual review, and HPV vaccine has a very good safety record.
