How repeated influenza vaccination impacts may apply to COVID-19 vaccines

Many current questions on future public health and research aspects of COVID-19 vaccines and vaccine strategies have been the subject of research and debate in the influenza vaccine literature for decades. Here, we describe how lessons learned from the study of repeated influenza vaccination may be applied to the evaluation of COVID-19 vaccines and the possibility of future seasonal or periodic booster vaccinations.

There are many differences between the design and manufacture of vaccines for COVID-19 and influenza, the immunological context, and effectiveness in preventing disease. Nevertheless, since both SARS-CoV-2 and the influenza virus are constantly evolving and can evade vaccine-induced immunity, and since protection from both vaccines declines over time,
