The flu vaccine was developed by American virologist Dr. Jonas Salk in the 1930s in response to the urgent need for a preventive measure against influenza, a highly contagious respiratory disease responsible for a large number of deaths worldwide.

During World War II, the flu vaccine maintained the health of the military personnel. The crowded conditions of military barracks and troop transports created ideal conditions for the rapid spread of diseases like influenza. Recognizing the potential impact of outbreaks on military operations, the Allied forces made vaccination campaigns a priority in order to protect soldiers from illness. By immunizing troops against influenza, the vaccine helped prevent the risk of outbreaks. This ultimately saved countless lives and helped prevent the spread of the disease worldwide.

Detecting and Tracking the Enemy With Radar

Radar, an acronym for Radio Detection and Ranging, was invented during World War II. It was used to detect and track objects over great distances using radio waves. The groundwork for radar was laid by numerous scientists and engineers, but it was Sir Robert Watson-Watt and his team in Britain who made major improvements in its development. Their work led to the first operational radar system, which helped Britain in the Battle of Britain.

Radar played a few different roles in winning World War II. Its ability to detect incoming enemy aircraft allowed Allied forces to anticipate attacks and prepare defenses more effectively. Radar-equipped ships also gained a crucial advantage in naval battles, allowing them to detect enemy vessels and aircraft at greater distances. Perhaps most famously, radar was used in the Battle of the Atlantic, where Allied radar-equipped aircraft and ships helped to detect and destroy German U-boats, turning the tide in the Allies' favor.
