Bill Gates still sends that particular vaccine to the Third World.  |
it's weird you claim to be the enlightened one.

Rotary, the World Health Organization, and the Centers for Disease Control and Prevention use the oral polio vaccine, and not the shot that American kids get.
The polio shot was actually invented first ? this is the same basic vaccine introduced by Jonas Salk in 1955. The oral polio vaccine, given as drops into the mouth, is the rival version that developed by Albert Sabin and introduced in 1961. The Salk shot contains dead polio virus that trains the immune system to react to the live kind; the Sabin drops are a weakened polio virus.
The U.S. switched to Sabin?s drops after he conducted a clinical trial in which he was able to virtually eliminate polio in Cincinnati. Since then, everywhere that polio has been eliminated, it has fallen to the drops, not the shots. Unlike the Salk shot, the drops don?t need to be given by a health care professional (see the anecdote about Bill Gates and the President of Chad giving them to kids in my story). The weakened virus can also spread from the stool of vaccinated kids to others, effectively widening the number of people who have gotten the vaccine and creating herd immunity.
But the U.S. switched back to the Salk shot. Why? Because in one in a million people, the Sabin drops can actually cause polio. There?s a clear explanation of why this decision was made in the the package insert contained in the Salk shot made by drug giant Sanofi. When the Sabin drops replaced the Salk shots, the annual rate of polio fell from one case per 200,000 people to one case per 2,000,000 people. At that point, the tiny risk of the vaccine causing polio became too great. Of the 127 cases of paralysis-causing polio in the U.S. between 1980 and 1994, 119 were caused by the oral Sabin vaccine. In 1999, the U.S. switched to giving all kids the shot.
