Those who got a flu shot may be less likely to suffer a severe COVID-19 infection, new research found. The study, published in the journal Plos One on Wednesday, analyzed the electronic medical records of more than 74,700 people from the United States, the United Kingdom, Italy, Germany, Israel and Singapore, who tested positive for COVID-19. Researchers found that those who had gotten the flu vaccine during the previous six months were less likely to have had health complications related to their COVID-19 infection. Specifically, researchers found that those who didn't get flu shots were up to 20% more likely to be admitted to the ICU; up to 58% more likely to visit the emergency room; up to 45% more likely to develop sepsis; up to 58% more likely to have a stroke; and 40% more likely to develop deep vein thrombosis, compared with those vaccinated against the flu.
