Inhalable Dry Powder COVID Vaccine: China's Groundbreaking Advancement
A new study published in Nature reports on a promising next-generation COVID-19 vaccine that can be inhaled as a dry powder, bypassing the need for cold chains and injections. The current injectable vaccines are less effective in preventing infection by evolving variants and inducing immunity in the airway mucosal tissues. This inhalable dry powder vaccine shows potential in inducing robust immunity in the respiratory mucosal tissues, which is the site of SARS-CoV-2 entry. It could be particularly beneficial for high-risk populations and eliminate the need for frequent booster injections.
