The flu vaccine reduces the risks of severe effects caused by coronavirus infection. A relevant study was carried out by physician-scientists at the University of Miami Miller School of Medicine, as Medical Xpress reports.
“The analysis revealed that those who had not had the flu shot were significantly more likely (up to 20% more likely) to have been admitted to the intensive care unit. They were also significantly more likely to visit the emergency department (up to 58% more likely), to develop sepsis (up to 45% more likely), to have a stroke (up to 58% more likely) and a DVT (up to 40% more likely). The risk of death was not reduced," the message writes.
Although it isn't exactly known yet how the flu vaccine provides protection against COVID-19, most theories speculate that the flu shot may boost the innate immune system—general defenses we are born with that do not protect against any one specific illness.
According to the scientists, the results strongly suggest that the flu vaccine may protect against several severe effects of COVID-19.
However, they strongly recommend that people get the Covid-19 vaccine, as well as an annual flu vaccine to avoid a possible 'twindemic'—a simultaneous outbreak of both influenza and coronavirus.
As it was reported earlier, the one-time vaccine of Johnson&Johnson could potentially protect people against Delta strain of coronavirus.
