Flu vaccines are a kind of injection which offer protection from the disease spread by influenza virus. While the jabs have been pushed into use for a long time now, the flu vaccines have been clinically tried and tested to curb the severity and mortality rates with the flu infection, which can be particularly helpful for those who are at a higher risk. The efficacy of these flu vaccines has also been found to be over and above the WHO criterion. Just like COVID-19, flu can be a respiratory infection which can cause severe symptoms, including pneumonia, and reduces the overall risk of hospitalization as well.

Having said that, while both are respiratory infections caused by viruses, there are some notable differences between the vaccines. Flu vaccines and COVID-19 vaccines are built using different technologies but have the same job of training our immune system.

As for the efficacy, while there again is a considerable difference, with some experts feeling that the COVID-19 vaccines do a better job at protection and severity reduction, it’s also thought that the COVID vaccine technology can help improve the protective features, workability of existing vaccines, including the flu shot.
