Vaccine effectiveness

Vaccine effectiveness is the percentage reduction of disease cases in a vaccinated group of people compared to an unvaccinated group.

\[VE = \frac{ARU - ARV}{ARU} * 100\]

Where
VE = Vaccine effectiveness,
ARU = Attack rate of unvaccinated people (new cases in unvaccinated / total unvaccinated),
ARV = Attack rate of vaccinated people (new cases in vaccinated / total vaccinated)
