Researchers confirm newly developed inhaled vaccine delivers broad protection against SARS-CoV-2, variants of concern

Scientists at McMaster University who have developed an inhaled form of COVID vaccine have confirmed it can provide broad, long-lasting protection against the original strain of SARS-CoV-2 and variants of concern. The research, recently published in the journal Cell, reveals the immune mechanisms and significant benefits of vaccines being delivered directly into the respiratory tract, rather than by traditional injection. The laboratory and the researchers are part of McMaster’s Global Nexus for Pandemics and Biological Threats.-- More...
