They already have that base covered. They say you can still catch and spread covid even when vaccinated, it only suppresses the symptoms. They've been saying for a while that masks, distancing, and lockdowns "must" continue because it can still be spread.

Which begs the question, why force or coerce people to take the vaccine if the only thing it does is affect the individual and make it so they don't feel sick or as sick? It's a decision that affects only yourself, so why get so pushy about making people take it?
