Six months into the largest vaccination effort in modern history, Pfizer and BioNTech have offered the world a measured reassurance: their messenger RNA vaccine holds firm at 91.3% efficacy, a modest retreat from early promise but a confirmation that science can keep pace with a virus in motion. More striking still, in a small cohort in South Africa — ground zero for one of the most worrying variants — not a single vaccinated participant contracted the B.1.351 strain, while six placebo recipients did.
