I would trust Dr Dodd's reccomendation over the one posted on the Foster fand Smith site. If am always sceptical when someone selling the vaccine makes the recdomendatioln.
if you went by their reccomendation, from earliest 6 weeks, to latest 20 weeks, at 3 week intervals, you would be vaccinating 5 to 6 times.
