Historical Moments in 21 Days
The 'Miracle of Dunkirk' Evacuation (1940)
During World War II, the evacuation of Allied forces from Dunkirk, France, was accomplished in a massive operation that lasted about 21 days. Between May 26 and June 4, 1940, a combination of military and civilian vessels rescued approximately 338,000 British and French troops trapped by advancing German forces. This large-scale evacuation was executed under intense pressure and adverse conditions, marking a critical moment in the war.
Development of Pfizer-BioNTech’s COVID-19 Vaccine Prototype (2020)
When the genetic sequence of SARS-CoV-2 was published in early January 2020, researchers at BioNTech, in collaboration with Pfizer, rapidly set to work on developing a vaccine. Within just 21 days, BioNTech had designed the initial mRNA vaccine prototype (later known as BNT162b2). This incredible speed in creating the prototype set the stage for subsequent testing, regulatory approval, and mass production, ultimately leading to one of the first widely distributed COVID-19 vaccines.
