JCVI using flawed evidence to reject HPV vaccinations
The BDA has accused the JCVI of using flawed modelling as a basis to reject HPV vaccinations in all children.
The British Dental Association (BDA) believes the methods the JCVI used in its studies could give an over-conservative estimate of the benefits that come with vaccinating all boys, leading the JCVI to a misguided conclusion on cost-effectiveness.
‘It is shocking that 400,000 boys a year can be left at risk of oral cancer thanks to a decision that cannot be properly scrutinised,’ BDA chair, Mick Armstrong, said.
‘Based on the scant information the JCVI has made public, its verdict is based on false assumptions.
‘The JCVI is failing in its duty as public body to treat all our children equally.
‘Expanding the pilots to vaccinate men who have sex with men attending sexual health clinics provides too little protection too late.
‘Only a gender neutral vaccination programme can offer all our children the best defence.’
HPV is the leading cause of oropharyngeal cancer, particularly amongst young people, with figures showing rates rising steeply.
It has also been linked to 5% of all cancers worldwide, including cancers that only affect men, despite this the current HPV vaccination programme only vaccinates school-age girls.
The BDA has outlined three areas that undermine the JCVI’s conclusions:
- The JCVI has used under-estimates of the proportion of cancers that are caused by high-risk HPV types
- Data used to model sexual behaviour are out of date, and factors such as the recent introduction of dating apps may have led to significant changes in behaviour over the last few years, which have not been taken into account
- Models have been over-simplified and have ignored factors such as increasing oropharyngeal cancer incidence, the full societal costs of treating diseases caused by HPV, transmission of the virus to men from unvaccinated UK or foreign women, and reduced vaccine uptake following safety scares.
JCVI have been approached for comment.
