Just found out that a co-worker is isolating himself for a few days because he was close to someone who is now positive for the China Virus. The catch: He's been vaccinated. I asked our boss - he's been vaccinated with both doses, so why? The answer was "you never know".
I said "then what is the point of getting a vaccine if we still have to worry", got up, and went back to work. This will help my cause if they ever want to press me to get it.
No vaccination gives you 100% immunization.
