About 15 years ago in the gym they experimented with facial recognition (for access) and abandoned it not so long afterwards. There's lots of #falseMarketing by companies looking to profit from it.
Theory: Russian and Chinese vaccines are about as effective as the Western ones, but they're lying less, the #falsemarketing (control of narritive in Western press) doesn't rely on blaming "variants" (as if mutation was unprecedented and foreseen?)
Higher than 95% efficacy? It's called properly masking and distancing (perfect efficacy). We've already witnessed evidence that claims of efficacy from the vaccine giants were #falseMarketing (nowhere near 95%)
A lot of people who still get infected with #covid19 are poor people who sadly cannot isolate (shared housing and in-person jobs) or rich COVIDiots who believe #falseMarketing ... to the point of thinking that being vaccinated makes them invulnerable. So they spread it to other people, too...
