The most recent study, which has been published in the medical journal PLOS and conducted on a pool of more than 37,000 patients examined crucial health parameters and hospitalization risk of patients who had tested COVID positive, weeks or months after getting the flu shot. Among the set of patients, it was observed that not only was the flu shot significantly effective, it was able to reduce the risk of severe outcomes with COVID for upto 120 days after vaccination.

In particular, while getting the flu shot was able to prevent the risk of hospitalization for some people, it was also seen that getting the vaccine could tame the risk of COVID complications like sepsis, deep vein thrombosis and time spent in hospital in COVID patients.
