Abstract

Vaccines against SARS-CoV-2 have changed the course of the COVID-19 pandemics, but waning immunity necessitates repeated immunization. Authors here show that immunity declines faster following two doses of vector-based vaccine compared to a first dose of vector-based vaccine followed by boosting with an mRNA vaccine, but application of an mRNA vaccine as a third dose minimises the difference between the two groups.
