Herd immunity and effectiveness of vaccination

A review paper being part of a larger educational project to promote knowledge on epidemiological methods among infectious disease doctors in Poland. My manager prof. Andrzej Zieliński invited me to contribute to prepare a plenary lecture and a review paper summarising methods used to measure vaccine effectiveness. This was my first experience giving a plenary speach during the opening ceremony of a large Congress of the Polish Society of Epidemiologists and Infectious Disease Physicians. I am not sure if my educational effort was successful, since the lecture was a bit technical and participants expected some general strategic lecture during the opening ceremony :)
