Beth, you are referring I think to the issue of serotype replacement. This happens when strains of the infection that are not covered by the vaccine try and fill the niche left behind as infection rates drop. However, with all the vaccines I know about, the replacement is still a tiny fraction of the previous total. So no, the total numbers of cases are not the same, they are still significantly less. The main vaccine this occurs with is pneumococcal, but it also affects others.
Antivaxers will point to serotype replacement, trying to disguise the actual numbers so that someone with an eagle eye cannot imediately rumble them.
Here is a prime example, quoting word for word the paragraph from the "insideVaccines" blog:
Anyone reading this would be rather scared that by preventing Hib B, all one was doing was replacing it with even more type A than there was type B to begin with.
The actual source
of the "cherry picked" quote says this:
As you can see, in red
I have added the sections that were deliberately removed from the quote on "InsideVaccines".
