Flu Vaccine Could Help Against Covid-19, Studies Suggest

According to recent studies, getting a flu shot could help reduce the impact of Covid-19 coronavirus.

Persons receiving a flu vaccine two weeks to six months before getting diagnosed with covid had lower rates of sepsis, strokes or deep vein thrombosis, and were less likely to visit emergency rooms or require an ICU.

In other words, while a flu vaccine is not intended specifically to inoculate against Covid-19, the sampled data suggested that covid-sufferers previously receiving a flu shot had a better chance of avoiding some of the more severe covid outcomes.

Publishing their findings in the journal PLOS ONE, the researchers concluded that there is a "potential protective effect of influenza vaccination in SARS-CoV-2-positive patients against adverse outcomes within 30, 60, 90, and 120 days:"

Our analysis outlines the potential protective effect of influenza vaccination in SARS-CoV-2-positive patients against adverse outcomes within 30, 60, 90, and 120 days of a positive diagnosis. Significant findings favoring influenza vaccination mitigating the risks of sepsis, stroke, deep vein thrombosis (DVT), emergency department (ED) & Intensive Care Unit (ICU) admissions suggest a potential protective effect that could benefit populations without readily available access to SARS-CoV-2 vaccination. Thus further investigation with future prospective studies is warranted.
