The COVID-19 pandemic saw the rise of multiple strains that put the companies manufacturing vaccines through their paces to keep up. With the FDA approving new vaccines for the latest substrains of the Omicron Variant, it seems that COVID-19 Cases are finally slowing down. These Emergency Use Authorizations were pushed through in a manner of days, marking them as some of the fastest ever in FDA history. However, they were based upon mountains of prior research done on their predecessors for prior strains as well as the heavily mutated Omicron Strains.
How do these vaccines function differently from their prior counterparts? And will these boosters bring about the end of the COVID-19 pandemic after so many strain mutations?
