The invention discloses a vaccine inoculation time deduction plate for children within one year old. The vaccine inoculation time deduction plate is characterized by designing a small circular plane plate 1, drawing six concentric circles in the small plate 1, dividing all concentric circles into twelve equal arc surfaces 2 on a circumference, respectively labeling vaccine names including "hepatitis B", "poliomyelitis", "diphtheria-pertussis-tetanus", "measles", "Japanese encephalitis", "group A" and "bacillus calmette-guerin" words in a radial column of the arc surfaces 2 according to a sequence from outside to inside, respectively digging a hole 4 in other arc surfaces 2 corresponding to the vaccine names according to a vaccine usage time and then arranging a big plate, drawing seven concentric circles in the big plate, writing "intramuscular injection", "oral administration", "intramuscular injection", "subcutaneous injection", "subcutaneous injection", "subcutaneous injection" and "intracutaneous injection" words on each of the concentric circles, overlapping the small plate 1 to the big plate 5, and arranging a connecting shaft 3 on the small plate 1 and the big plate 5. By rotating the small plate 1, the words displayed in the holes 4 are an inoculation sequence, an inoculation method and an inoculation time.
