Fridge-free COVID-19 vaccines, grown in plants and bacteria
Nanoengineers at UC San Diego are developing COVID-19 vaccines that don't require refrigeration. Their key ingredients? Viruses from plants or bacteria. These fridge-free vaccines are still in the early stage of development. In mice, the vaccine candidates triggered high production of neutralizing antibodies against SARS-CoV-2, the virus that causes COVID-19. If they prove to be safe and effective in people, the vaccines could be a big game changer for global distribution efforts, including those in rural areas or resource-poor communities.
