Healthy vaccinee effect in practice
Original language description
We would like to thank Pietrzak et al for responding to our commentary on their original paper on COVID-19 vaccination effectiveness. In our letter, using data from the Czech Republic, we showed that the population opting for vaccination was generally healthier than the unvaccinated one, which causes a significant selection bias and makes any calculation of vaccine effectiveness problematic. In their response, Pietrzak et al asked us for an explanation of a seemingly strange phenomenon, namely, that there was virtually no difference in all-cause mortality (ACM) among the unvaccinated individuals aged 50 to 79 years between the low- and high-COVID periods. This is actually an excellent point demonstrating the importance of careful interpretation of the data and how big a role the selection bias could play. We explain this in our current letter.
