The coronavirus and the flu are two entirely different viruses. But a new study suggests those who get a flu vaccine face a considerably lower risk for being hospitalized if and when they get COVID-19.
And the flu vaccine also appears to significantly reduce a COVID-19 patient's risk for ending up in an intensive care unit (ICU), researchers say.
The findings are based on an analysis of electronic health records for 2,000 COVID-19 patients. All had tested positive for the virus at some point between this past March and August. And just over 10% of the patients had previously been vaccinated for the flu.
"The flu and COVID-19 are indeed different disease processes caused by different viruses," stressed study author Dr. Ming-Jim Yang. "Although some of the symptoms may overlap between the two diseases, they potentially have different short-term and long-term consequences."
