How to roll your sleeves when vaccinating in winter?

In winter, we don't feel as convenient as in summer, because it's cold in winter and we wear a lot of clothes. It's really not as convenient to show our shoulders when giving injections as in summer. But we should keep warm, try to wear loose clothes inside and thick clothes outside, so that after taking off the outside during the injection, the inside can be treated as soon as possible. Because of the injection, it is not easy to catch a cold.
