Immunogenicity of Oral Polio Vaccine and Salk Inactive Polio Vaccine Against Xinjiang Imported Type 1 Wild Poliovirus

Hormesis and the salk polio vaccine.

The production of the Salk vaccine polio virus by monkey kidney cells was generated using the synthetic tissue culture medium, Mixture 199. In this paper's retrospective assessment of this process, it was discovered that Mixture 199 was modified by the addition of ethanol to optimize animal cell survival based on experimentation that revealed a hormetic-like biphasic response relationship. This...

Live Oral Poliovirus Vaccine after DPT Polio Vaccine.

In the editorial note on Controlled Drugs which I contributed to the issue of September 9 (Canad. M. A. J., 85: 661, 1961), I find that I have overstated the case for written prescriptions for the amphetamines and the barbiturates. Pharmacists may dispense Controlled Drugs on the strength of a prescription given verbally by a physician as well as by a prescription in writing. The pharmacist mus...

Molecular analyses of oral polio vaccine samples.

It has been suggested that the human immunodeficiency virus (HIV), and thus the acquired immunodeficiency syndrome (AIDS) it causes, was inadvertently introduced to humans by the use of an oral polio vaccine (OPV) during a vaccination campaign launched by the Wistar Institute, Philadelphia, PA, USA, in the Belgian Congo in 1958 and 1959. The "OPV/AIDS hypothesis" suggests that the OPV used in t...

Polio vaccine and retroviruses.

In this paper we consider the main steps in the process of manufacture of oral polio vaccine and assess the probable clearance factor for HIV retrovirus at each step. We conclude that the processes employed would have eliminated retrovirus contamination for all practical purposes.
