Don't know if these numbers are accurate, but the trend is true from data I found at John Hopkins.
Coincidence?
@Truther - The numbers add up. I don't get the 1983 numbers on the image you posted. At the top is shows 11 vaccines for 1983, but in the bottom corner it says total doses of 24 for the same year.
DTP is actually 3 vaccines combined into one injection. The same goes for MMR.
OPV is one vaccine, but not a jab because it is administered orally.
