The vaccine has been extensively tested and has been in use in many other countries, including, Australia, UK, USA and India, to mention a few. There have been no major adverse (unexpected) events attributed to the vaccination.
As with all vaccinations, some children may experience some bruising or redness at the vaccination site. In very few cases, due to nervousness and anxiety, some girls have reported vomiting and nausea, although this seems to be at the thought of being injected rather than a response to the vaccine!
The vaccine contains nothing that can cause cancer or other illnesses.
