Professor Nick Andrews

With an increasing number of vaccines recommended in pregnancy it is important to consider how best to evaluate safety. There are particular challenges in assessing safety in pregnancy such as healthy vaccinee effects, immortal time bias and biases introduced in the days close to birth. In this talk I will discuss these challenges and consider different designs with pros and cons, this will include presenting a study I have done using a nested case -control study within a cohort for Covid-19 vaccine safety and plans for a target trial emulation approach for assessing RSV vaccine in pregnancy.
