Some inoculation points are after the first injection, and there is no need to make an appointment for the second or third injection; However, some inoculation sites still need to make an appointment for two or three shots after the first shot. For example, in August of 20021year, a batch of nine-valent vaccines arrived in Xinyang city. When these nine-valent vaccines arrive, they need to make an appointment for the first, second or third shots. Generally speaking, whether it is necessary to make an appointment for two or three stitches depends on the inoculation point and the arrival of specific batches of seedlings.
