Are Harmless, Dr. Salk Says Influenza vaccines considered "impure" from the chemist's view- point have no more unfavorable reactions than those chemically purified, Dr. Jonas E. Salk of the epidemiology department of the School of Public Health asserted yesterday. Commenting on the statement made by Dr. Wendell M. Stanley of the Rockefeller Institute of Medical Research when he spoke here last Friday before the Ameri- can Chemical Society, that "im- pure vaccines may be responsible for unfavorable reactions," Dr. Salk said that tests made at the School of Public Health show sim- ilar results for all vaccines now in use. Dr. Salk, who worked with Dr. Thomas Francis, Jr., in developing the first effective influenza vac- cine, explained that the virus con- tent and not the degree of chemi- cal purity affects an individual's reaction to the vaccine. The virus content of vaccines is standardized by the Division of Biological Con- trol of the National Institute of Public Health which will license only safe, effective vaccines, Dr. Salk pointed out. The safety of the vaccines which Dr. Stanley cautioned against is attested to by the lack of unto- ward reactions resulting from their use in army, and later in campus, influenza immunization, Dr. Salk declared. He said that all vaccines in use at present are prepared from chick embryo fluid and for this reason it is unsafe to administer them to egg-sensitive individuals. The decision as to which vaccine should be used for influenza inocu- lations should reside with the in- dividual physician, Dr. Salk said. Fitch comedy To Be Given The opening performance of "The Truth," a comedy by Clyde Fitch, will be given by Play Pro- duction at 8:30 p.m. today in Lydia Mendelssohn Theatre.
