On May 12, 2021, Inovio Pharma announced that its next-generation Pan-COVID-19 vaccine candidate, INO-4802, induced potent neutralizing antibodies and T cell responses against the original Wuhan strain as well as against B.1.1.7 (UK variant), B.1.351 (South African variant) and P.1. (Brazilian variant) in preclinical models.

These results demonstrated the potential of INOVIO’s Pan-COVID-19 vaccine to induce cross-reactive immune responses against current and emerging viral variants as either a first-line vaccine, or potentially as a boost for individuals previously immunized with various Wuhan-matched vaccines.
