Virus mutations aren’t slowing down. The vaccines currently deployed were all based on the genomic sequence of the original strain of the virus that spread in late 2019 in Wuhan, China. They essentially mimic the spike protein of that version of the virus and trigger an immune response that is protective when the real virus shows up.
But the variants that have emerged can evade many of the neutralizing antibodies that are the immune system’s front line of defense. “It’s evolving at a fairly rapid rate,” said Jesse Bloom, a computational biologist at the Fred Hutchinson Cancer Research Center in Seattle. “I do think we need to aggressively consider whether we should update vaccines, and do it soon.” (Washington Post, May 1, 2022)
