The polio vaccines prevented 29 million cases of paralytic polio between 1960 and 2021, compared with a counterfactual world with no vaccines, according to researchers’ estimates.
The risks and possible side effects of the polio vaccine are comparable to those of other vaccines, the CDC says, such as pain, soreness, swelling, and/or redness at the injection site. Fainting ...
The first accident involving a 737 was on July 19, 1970, when a 737-200 was damaged beyond repair during an aborted takeoff, with no fatalities; the first fatal accident occurred on December 8, 1972, when United Airlines Flight 553 crashed while attempting to land, with 45 (43 on board plus 2 on the ground) fatalities; and, as of February 2024 ...
A few years later, during a polio outbreak in Canada, "masked bandits" stole 75,000 Salk vaccine shots from a Montreal university research center. [25] Just months after the vaccine's success was announced, American President Eisenhower signed the Polio Vaccination Assistance Act of 1955, to ensure the vaccine would be distributed to the public ...
On April 12, 1955, following the announcement of the success of the polio vaccine trial, Cutter Laboratories became one of several companies that was recommended to be given a license by the United States government to produce Jonas Salk's polio vaccine. In anticipation of the demand for vaccine, the companies had already produced stocks of the ...
The organization's annual fundraising campaign coincided with Roosevelt's birthday on January 30. The organization initially focused on the rehabilitation of victims of paralytic polio and supported the work of Jonas Salk and others that led to the development of polio vaccines. The modern March of Dimes focuses on preventing premature births ...
In the control group, Brodie reported that five out of 4500 developed polio; in the group receiving the vaccine, one out of 7,000 developed polio. This difference is not quite statistically significant, and other researchers believed that the one case was likely caused by the vaccine. Two more possible cases were reported later. [11]
In 1954, the National Institutes of Health delegated Eddy to perform safety tests for a batch of inactivated polio vaccines developed by Jonas Salk for Cutter Laboratories. Salk's inactivated polio vaccine was a killed-virus vaccine that was to be used in a massive national vaccination program.
