The SARS‐CoV‐2 spike ferritin nanoparticle (SpFN) is a COVID‐19 vaccine candidate produced per the abovementioned protocol by fusing the ectodomain of the prefusion S protein of SARS‐CoV‐2 with ferritin.[131] The SARS‐CoV‐2 spike ferritin nanoparticle paired with Alhydrogel® (ALFQ), a liposomal formulation and alum‐containing adjuvant, could provide broad neutralizing protection in nonhuman primates.[132] The SpFN+ ALFQ‐induced T‐cell response spectrum was further assessed in mice. This evidence concerns the gene PROS1 and COVID-19.
