The extent and impact of vaccine status
miscategorisation on covid-19 vaccine efficacy
studies
Abstract
It is recognised that many studies reporting high efficacy for Covid-19 vaccines suffer from various selection biases. Systematic review identified thirty-nine studies that
suffered from one particular and serious form of bias called miscategorisation bias, whereby study participants who have been vaccinated are categorised as
unvaccinated up to and until some arbitrarily defined time after vaccination occurred. Simulation demonstrates that this miscategorisation bias artificially boosts vaccine
efficacy and infection rates even when a vaccine has zero or negative efficacy. Furthermore, simulation demonstrates that repeated boosters, given every few months, are needed to maintain this misleading impression of efficacy. Given this,
any claims of Covid-19 vaccine efficacy based on these studies are likely to be a
statistical illusion.
