American study: influenza vaccination may reduce the severe effects of the Corona virus


A new US study revealed that people who are vaccinated against influenza may be partially protected from some of the severe effects of the Corona virus, and that this is also less likely to need hospitalization due to Corona, according to what the British newspaper “The Guardian” reported.


An analysis of nearly 75,000 COVID-19 patients found significant reductions in stroke, deep vein thrombosis and septicemia, and fewer admissions to emergency departments and hospital intensive care units, among those who received the flu vaccine.


Although the flu vaccine did not reduce coronavirus deaths in the study, previous research suggests that the vaccine may provide some protection against the coronavirus by boosting the innate immune system — the body's general defenses that aren't targeted against specific pathogens.


Another possible explanation is that patients who get the flu shot may be in better overall health than those who don't.


"We found an association that influenza vaccination provides some protection against severe COVID-19," said Devinder Singh, the study's senior author and professor of clinical surgery at the University of Miami.


If the results are backed up by more studies, they may be more valuable to countries that have not been able to compete with wealthier nations for coronavirus vaccines, so that the combined burden of influenza and coronavirus does not threaten to overwhelm health services and hospitals.


Professor Singh said: "It is very important to stress that we fully recommend the corona vaccine, and in no way are we suggesting that the flu vaccine is an alternative to the corona vaccine."


The researchers compared the electronic health records of 37,377 COVID-19 patients from the United Kingdom, the United States and elsewhere who had received flu vaccinations with the same number of COVID-19 patients who had not been vaccinated against the flu.


Patients in the two groups were closely matched for age, gender, ethnicity, health problems including diabetes, lung disease, lifestyle factors such as diet and whether or not they smoked.



Scientists analyzed how often patients experienced any of 15 potentially serious health effects ranging from blood clots and heart attacks to kidney and respiratory failure in the four months following their diagnosis.
