About The Study:

Covid-19 and influenza are extremely contagious respiratory viruses.  Though those with underlying medical conditions or weak immune systems are likely to become the most ill, these viruses can cause severe illness in healthy people in some instances as well.  As these viruses are constantly changing, the need for updated vaccines is important to decrease the risk of severe infection.

The purpose of this study is to evaluate the safety, tolerability and immune response of a combined mRNA flu/Covid 19 (updated Omicron XBB 1.5 version) vaccine compared to administration of separate Covid and Flu vaccines. A combination vaccine also helps to increase compliance among the population due to convenience.             

There is no cost to participate in this study and health insurance is not required nor needed.
