Still, research shows that the flu vaccine can help lessen the effects of COVID-19, which can be valuable in the overall fight to beat the pandemic. The first group had received the flu vaccine between two weeks and six months before contracting COVID-19, while the second group had not been vaccinated with the flu shot. The analysis showed that the group who had not received the flu shot were 20% more likely to be admitted to the ICU. It is not yet known how the flu shot protects the patients from the side-effects of COVID-19, according to the authors of the study. Ms. Taghoiff warned that despite the apparent benefits, the flu vaccine "is by no means a replacement for the COVID-19 vaccine" and urged everyone "to receive their COVID-19 vaccine if able to."
