Vaccination has emerged as an effective tool in preventing severe COVID-19 infections and reducing overall cases of hospitalisations. Currently vaccination is done through the traditional method of injecting the vaccine into the arm. However, nasal vaccines, which are currently under development, may hold the potential to prevent COVID-19 infection entirely, including the mild cases.
Scientists believe vaccines administered through the nose may be better suited to prevent the infection, compared to the shots administered intramuscularly. However, most nasal vaccines under development currently, will work like a booster dose.
