Vaccines have consistently demonstrated their efficacy in protecting people from infectious diseases. Yet, the recent COVID-19 pandemic highlighted the obstacles that are inherent today in the development of vaccines. Stabilizers play a crucial role in maintaining the vaccine's potency and integrity throughout its shelf life.
