Why do I need to wear a mask after COVID-19 booster injection and COVID-19 vaccine

Why COVID-19 vaccine should be given three shots

of different types of vaccines. Three doses of recombinant coronavirus vaccine (CHO cell) are required. The interval between the first administration and the second administration, as well as between the second administration and the third administration, should be greater than 4 weeks. The second administration should be completed within 8 weeks after the first administration. The third administration should be completed within 6 months after the first administration. Do I still need to wear a mask after getting vaccinated? Getting vaccinated is to establish a population immune barrier and reduce the chance of virus transmission. However, the number of vaccinated individuals is currently limited, and the health barrier has not yet been fully established. Therefore, even if someone is vaccinated, their awareness of epidemic prevention cannot be reduced. Corresponding preventive measures should be taken.
