Researchers at Tel Aviv University have developed an effective, inexpensive, and simple COVID-19 vaccine that can be stored at room temperature and administered as a nasal spray

Prof. Ronit Satchi-Fainaro’s lab at TAU’s Faculty of Medical and Health Sciences collaborated with Professor Helena Florindo’s lab at the University of Lisbon to produce a novel nano-vaccine for COVID-19. The nano-vaccine, a 200-nanometer particle, trains the immune system against all common COVID-19 variants, just as effectively as existing vaccines.

Moreover, unlike other vaccines, it is conveniently administered as a nasal spray and does not require a cold supply chain or ultra-cold storage. These unique features pave the way to vaccinating third-world populations, as well as the development of simpler, more effective, and less expensive vaccines in the future. The revolutionary study was featured on the cover of the journal Advanced Science.
