Why are you quarantined if you got vaccinated?
To not trust vaccination is to not trust science.
However, that's across the population. Factors like extended contact period increase viral load intake, could further decrease the effectiveness. Since my 4 month old can't get vaccinated against COVID yet, we decided it wasn't worth taking the risk.
Most vaccines have an efficacy lower than the COVID vaccines. Basically you are feeding off of your own fear, and you don't trust science. That's your right, but don't blame anyone for your self-imposed quarantine but yourself at this point.
