Flu vaccine reduces risk of severe coronavirus, scientists

Experts studied the data of more than 74.7 thousand patients from the USA, Great Britain, Italy, Germany, Israel and Singapore.

The flu vaccine reduces the risk of severe COVID-19, the study authors said.

It is noted that the researchers analyzed electronic medical records of more than 74.7 thousand patients from the USA, Great Britain, Italy, Germany, Israel and Singapore who tested positive for coronavirus.

The researchers found that those who received the flu vaccine within the previous six months were less likely to have health complications associated with COVID-19 infection.

At the same time, those unvaccinated from the flu were 20% more likely to end up in the intensive care unit and 58% more likely to go to the emergency room.

In addition, patients without the vaccine were 45% more likely to develop sepsis, 58% more likely to develop stroke, and 40% more likely to develop deep vein thrombosis.

It is indicated that the researchers found no link between getting a flu shot and a lower likelihood of dying from COVID-19.

The new study is consistent with several previous studies that have already claimed a link between mild COVID-19 and flu shots.

The authors, however, noted that these data do not necessarily indicate that the flu vaccine protects against the new coronavirus.

It is possible that the flu shot boosts immunity. Plus, people who choose to get the flu shot tend to be generally healthier than people who miss it, which means they're already at a lower risk of complications from COVID-19.

The experts recalled that the flu vaccine changes every season, so it is unclear if the vaccine developed for the 2020-2021 period will have the same association with the less severe course of the coronavirus as the 2019-2020 vaccine.

They also draw attention to the peculiarity of electronic health records, which is that different countries may report symptoms in different ways and use different tests to confirm the diagnosis of SARS-CoV-2, which can distort the data.
