Not entirely, but it's all we have in general. COVID-19 has mutation characteristics closer to H3N2 influenza than H1N1 strains. But this vaccine is so different from traditional "flu shots" that we are in uncharted territory. Early studies based on 42,000 test subjects showed a 95% efficacy (162 in the placebo group contracted COVID, 9 severe as opposed to 8 in the treatment group, 1 severe)
