Keep this in mind and it is taught to all kids in biology class and to ALL doctors, you can not get sick from the same virus twice. This is a fact and has always been the case. This is the concept actual vaccines were built on. This is why you don't see people getting measles, small pox, or polio after taking those supposed vaccines.
Since this is true, how is it possible that Biden supposedly got "covid" 3 times already when he took the supposed "covid" vaccine? Because it's all a scam. The supposed "covid" test simply tests for ANY corona virus as was shown in the inserts when the first covid test results were sent out to consumers. This means it's not testing for any specific virus so that test is a scam.
The "covid" shot is not a vaccine in any capacity or the supposed "covid" pandemic woulda been over as soon as all those idiots that took that shot did not have to worry about fictional "covid" ever again.
What the lunatics that run the world behind the scenes want is for people to get sick from the clot shot so that they can blame covid and institute more lockdowns and do what they are doing in China, institute the Social Credit System that MSN is making sure they don't talk about so nobody knows what the plan is.
Getting back to the original reply, a virus someone has destroyed and is immune from can make someone else sick and that is easier if you cough on them. And if they are sick, wearing a mask or not, it's entirely possible to get them sick as we all know when being around sick people in our life.
