What does it mean to express the COVID-19 vaccine?

Express delivery of COVID-19 vaccine means that the courier has been vaccinated with COVID-19 vaccine. The courier company stipulates that couriers must be vaccinated with COVID-19 vaccine. When the courier delivers the courier, he will send a message to the customer that the courier has been vaccinated with COVID-19 vaccine, suggesting that the courier has been vaccinated with COVID-19 vaccine, which is safe, so that the customer can rest assured of the courier.
