Intranasal vaccines the next step in COVID vaccines.
In a collective display of scientific advancement, the Covid-19 vaccines from Pfizer, Moderna and Johnson & Johnson seem to be astoundingly effective at preventing severe disease and death from Covid-19. All are intramuscular, meaning they are injected into the muscle tissue. Once the vaccine materials seep into the bloodstream, they induce the creation of antibodies, which then circulate in the blood throughout the body, protecting some of the most vital organs and creating what’s called systemic immunity. This immune response protects the body from serious illness and death, but the response only builds after the virus has fully entered the body.
Their ability to protect the human body from Covid-19 illness is truly incredible, but the SARS-CoV-2 virus still has an entryway into the body left unprotected by the vaccines: the nose and mouth. Those two gateways, and their ability to transmit the virus, are what mask mandates are all about. Face coverings have been shown to impede the spread of the aerosol virus, protecting their wearers and those around them from infecting each other.
