Alpo said:There is a lot of anecdotal evidence in your statements, which I'm sure you are aware. The polio vaccines have been tested for over 60 years. Yes, there was a batch of live virus that went out during the initial Salk vaccination that caused polio in some children. Those processes were corrected. Was the campaign effective? Yes. Prove otherwise, please. With data and test results. Not anecdotes. Sabin's test showed that the live virus would result in 1 child in 1 million developing the disease. It was one of the reason that the USA returned to the Salk vaccine in the 90's. However, where injections aren't the optimum delivery method for certain parts of the world, the Sabin vaccine is still used.
I provided zero anecdotes. I already provided the source. Here it is again:
