An injected vaccine was never going to cut a respiratory virus off from human reservoirs. The mucosal immune compartment has a nearly independent immune response, including antibody production. Mild and asymptomatic cases were never going to be prevented, and therefore neither was person-to-person spread. This is textbook immunology knowledge, so clearly the experts would have known this.
That's why the vaccine protects against serious illness and death, because at that point the virus has spread beyond the mucous membranes.
- shadowgovt 3y agoGood point. Now that you mention it, I can't think of any virologists that were claiming it was a two shots and done disease. It's more likely that people misinterpreted "after two shots quarantine is no longer necessary" as "the disease is eradicated after two shots."
