What's a nasal vaccine?

A nasal vaccination is one that is delivered through the nose. It can be inhaled as a spray or placed into the nose using a dropper.Nasal vaccinations are believed to provide protection against coronavirus. It is thought to be beneficial since the nose is frequently the primary point of entry for SARS-CoV-2, the virus that causes Covid-19 illness.
