Passage: Salks vaccine was then used in a test called the Francis Field Trial, led by Thomas Francis, Jr., the largest medical experiment in history at that time. The test began with about 4,000 children at Franklin Sherman Elementary School in McLean, Virginia, and eventually involved 1.8 million children, in 44 states from Maine to California. By the conclusion of the study, roughly 440,000 received one or more injections of the vaccine, about 210,000 children received a placebo, consisting of harmless culture media, and 1.2 million children received no vaccination and served as a control group, who would then be observed to see if any contracted polio. The results of the field trial were announced 12 April 1955 (the tenth anniversary of the death of President Franklin D. Roosevelt, whose Franklin D. Roosevelts paralytic illness was generally believed to have been caused by polio). The Salk vaccine had been 60-70% effective against PV1 (poliovirus type 1), over 90% effective against PV2 and PV3, and 94% effective against the development of bulbar polio. Soon after Salks vaccine was licensed in 1955, childrens vaccination campaigns were launched. In the U.S, following a mass immunization campaign promoted by the March of Dimes, the annual number of polio cases fell from 35,000 in 1953 to 5,600 by 1957. By 1961 only 161 cases were recorded in the United States.

Passage: After the tough home win over the Vikings, the Colts stayed home for a division rival duel against the Jaguars.  Scoring started early as the Jags drew first blood scoring a 44-yard field goal from Josh Scobee to take a 3-0 lead.  However, the Colts took the lead with Andrew Luck's 40-yard touchdown pass to T. Y. Hilton for a 7-3 lead.  The Colts increased their lead in the 2nd quarter with Andrew Luck's 4-yard touchdown pass to Mewelde Moore for a 14-3 halftime lead.  In the 3rd quarter, the Jaguars were able to fire back as Maurice Jones-Drew ran in a touchdown from 59 yards out to cut the lead to 14-10.  Followed up quickly by Scobee's 47-yard field goal to shorten the lead to a point 14-13.  In the fourth quarter, the Jags were able to take the lead with Scobee kicking a 26-yard field goal for a 16-14 lead.  The Colts however retook the lead with Vinateri's 37-yard field goal for a 17-16 lead.  But then the Jags were able to complete the comeback attempt 11 seconds later with Blaine Gabbert's touchdown pass to Cecil Shorts III (with a failed 2-point conversion) to make the final score 22-17.
