What are the good things that can happen from this research?
You may or may not personally benefit from your participation in this trial. However, by taking part, you will help to provide new scientific information that will contribute to the development of COVID-19 vaccines.
What are the bad things that can happen from this research?
As with any vaccine, you may have side effects. Expected side effects common from intranasal vaccines include runny nose/nasal congestion, sore throat and cough. You may have discomfort from having blood draws and nasal swabs. We will discuss possible risks and discomforts with you prior to the start of the study.
