As the world grappled with vaccinating against Covid-19 last year, a mix-and-match approach to jabs emerged as a potential solution to roadblocks like vaccine hesitancy, safety concerns, and supply chain issues.
In the months since, numerous studies have shown that administering different Covid-19 vaccines for the first and second doses induces a strong immune response against the novel coronavirus, and recent research has even suggested that mixing jabs is more effective than administering two doses of the same vaccine.
