Reply To: EXPLAINER: Covid Regulations Post-Vaccine

to previous questions from Participant, according to my limited understanding:
vaccines increases immune response. Yes, it may move someone from symptomatic to asymptomatic, but at the same time, it will prevent someone else from asymptomatic transmission at all. Very weak vaccines, like Chinese, seem to be creating problems on countries like Mongolia, possibly because of immediate relaxation of rules. Vaccines create 2 responses – antibodies and T-cells. Antibodies prevent transmission and also decrease with time and possibly with variants. T-cell take time to respond, so they prevent serious illness but not transmission. T-cell response may even improve with time and is covering more variants. In the same Mongolia, cases skyrocketed, deaths increased way less, at least for now.
