Vaccine efficacy and immune interference: co-administering COVID-19 and influenza vaccines

As we head towards the second anniversary of the COVID-19 pandemic, attention widens to encompass the array of unforeseen health-care consequences of these unprecedented times and measures. In this context, efforts have been made to analyse data and predict how the winter months will look in terms of the interplay between infections by SARS-CoV-2 and other common respiratory viruses, influenza, and respiratory syncytial virus. To an extent, there is still no consensus in the scientific and medical communities as to the risk and impact of concomitant respiratory infections: on the one hand, lockdown and other mitigations that have limited the spread of COVID-19 would be predicted to have limited influenza and respiratory syncytial virus too.
