Dr Sandy Douglas, who’s main the examine, stated: “Some immunologists imagine that delivering the vaccine to the positioning of an infection could obtain enhanced safety, particularly in opposition to transmission, and gentle illness.
“We hope this small safety-focused examine will lay the muse for future bigger research which are wanted to check whether or not giving the vaccine this manner does defend in opposition to coronavirus an infection.”
Dr Douglas added: “There are a selection of people that will discover an intranasal supply system extra interesting, which can imply vaccine uptake is increased in these teams.
“It may also have sensible benefits – nasal sprays have been used efficiently for different vaccines, for instance the flu vaccine utilized in UK colleges.”
Dr Meera Madhavan, lead scientific analysis fellow on the Jenner Institute, stated: “This examine will assist us to grasp the protection of, and side-effects related to, giving the Oxford/ AstraZeneca Covid-19 vaccine by nasal spray.
