I'm not suggesting anything nefarious is in the works, I just don't trust the DS, the medical profession, anyone connected to the 3 letter agencies, the MSM, several coworkers, a neighbor or two, etc. That leaves the rest of us having to look out for each other.

Scientists have developed aerosolized COVID-19 boosters that, when inhaled, appear to stop infections in their tracks. In trials involving monkeys and rodents that had already received vaccinations, the boosters successfully increased immune responses in COVID-19’s home base: the respiratory tract. The hope is that the aerosols could lead to simple, accessible booster doses that prevent—not just help fight—infections.
