From December 2019 to early March 2020, the local outbreak of novel corona virus disease (COVID-19) in central China’s Hubei region has grown into a worldwide pandemic. This rapid and catastrophic escalation makes the search for and understanding of the underlying mechanisms of infection and disease, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as well as of their associated risk factors an urgent priority. To approach this goal, the unprecedented multitude of online monitoring data produced during the current SARS-CoV-2 outbreak may be helpful: it now allows nearly instantaneous epidemiologic hypothesis testing on a pandemic level. Here we show that reported influenza vaccination coverage rates for 29 OECD countries are associated significantly with recently observed SARS-CoV-2 infection rates in these countries. This early result, which merits further investigation, suggests that during the current coronavirus outbreak an influenza vaccination background might be a relevant factor for SARS-CoV-2 infection.
