Good point, RunnerReader. People who are vaccinated can still contract the virus and for a short duration potentially spread it to others, but the body's lymphocytes (B-cells and T-cells) will go into full attack mode and quickly neutralize the virus. At that point, transmission of the virus to others will become a non-event and the life cycle of the SARS-Cov-2 virus will eventually end (or be reduced to the point where it will not be a health risk to the general population). And, all of this concern about the different COVID variants makes for sensational journalism, but the vaccines developed thus far and those coming next month should have no problem neutralizing any present mutation to this virus.
