Intranasal vaccine is an uncommon type of vaccine where it is administered in solution form via the nostril. It is sprayed into the nostril and is inhaled for uptake- instead of the usual intramuscular or subcutaneous routes of administration. It reduces the need for syringes, needles and alcohol swabs. Its non-invasive nature prevents needle-associated infections. The recently announced BBV154 vaccine from Bharat Biotech is an intranasal vaccine against COVID-19. Only a single dose of this vaccine is required per person.
