Tel Aviv University researchers developed a COVID-19 vaccine that can be stored at room temperature and administered as a nasal spray, breaking Pfizer and Moderna's duopoly. The nanovaccine, composed of 200-nanometer particles, trains the immune system against all common variants and doesn't require cold storage, making it ideal for developing countries.

Israeli and Portuguese scientists developed a Covid-19 nano-vaccine stored at room temp, administered as a nasal spray, effective against all variants, and potentially paving the way for simpler, more affordable vaccines.
