Conventional vaccine manufacturing approaches using whole inactivated virus (WIV), protein-based subunit vaccines, and virus-like particles (VLPs) may offer advantages in the development of vaccines for use in low- and middle-income countries and in addressing vaccine access gaps.
Other researchers are betting on inhaled vaccines, which come in the form of aerosolized mists administered through a nebulizer into the lungs, where the virus tends to wreak the most havoc.
