Single dose nasal vaccine against SARS-CoV-2 shows promise in animal studies

Now researchers at the Washington University School of Medicine in St. Louis have worked on developing a candidate vaccine against the infection that could be administered in a single dose via a nasal spray rather than an injection. In their preliminary studies using lab mice, this single dose of the nasal vaccine successfully prevented the infection with the novel coronavirus.
