Will there be a need for a mask after vaccination?

Although the vaccine protects the person to whom the vaccine is administered at a certain level, we will continue to use masks for a long time as there will still be a risk in terms of carrier for those who are not vaccinated. The vaccinated person can be protected from the disease, but if they come into contact with the virus, the infectiousness will remain the same, so it will continue to be a threat to those who have not yet been vaccinated. Therefore, the use of masks is essential for both vaccinated and unvaccinated people. In order to continue to protect both ourselves and others, we need to continue using masks for a while.
