Answer: The greater risk of death and injury places pressure on scientists to come up with advancements.
Step-by-step explanation:
In less than a year after the world began to feel the effects of the Coronavirus pandemic, vaccines were rolled out. This is an astronomical achievement because vaccines usually take longer but the devastating effects of this pandemic prompted scientists to come up with a vaccine faster than usual.
This was the same during wartime. In war, it is in a country's best interest to lose as little life as possible which is why governments invest in medicine during war to mitigate losses. This leads to scientists coming up with ways to save more lives. Instances of these include the use of frozen blood in the Vietnam war and the use of anaesthesia in the American Civil War.
Another reason for medical advancements during war is the unexpected effect of weapons on soldiers leading scientists to research more on these weapons. For instance, poison gas in the first World War killed normal cells in soldiers which laid the foundations for chemotherapy.
