Polio vaccine. Polio vaccines are vaccines used to prevent poliomyelitis (polio).[1] There are two types: one that uses inactivated poliovirus and is given by injection (IPV), and one that uses weakened poliovirus and is given by mouth (OPV).
The Hippocratic Oath. The Hippocratic Oath (Î¿ÏÎºÎ¿Ï) is perhaps the most widely known of Greek medical texts. It requires a new physician to swear upon a number of healing gods that he will uphold a number of professional ethical standards. It also strongly binds the student to his teacher and the greater community of physicians with responsibilities similar to that of a family member.
The oath is written in Ionic Greek, and is usually included in the Hippocratic Corpus. Classical scholar Ludwig Edelstein proposed that the oath was written by Pythagoreans, a theory that has been questioned due to the lack of evidence for a school of Pythagorean medicine.
