Study after Study after Study is showing COVID-19 antibodies are present only for a few weeks in people after they recover. "Natural Herd Immunity" is a myth.

- A major new study in one of Europe's worst affected countries for the coronavirus finds no evidence of widespread immunity to the virus developing.
- Just 5% of Spaniards were detected to have antibodies to the virus.
- Fourteen percent of people who previously tested positive for antibodies tested negative just weeks later.
- The study suggests people who experience mild symptoms do not have long-lasting protection.
- "Immunity can be incomplete, it can be transitory, it can last for just a short time and then disappear," Raquel Yotti, the director of Spain's Carlos III Health Institute, said.
- Another scientist involved said: "In light of these findings, any proposed approach to achieve herd immunity through natural infection is not only highly unethical, but also unachievable."
I think this was pretty much a given when we found out that this was a coronavirus.
but... younger people?
