It was the year 1956 and the world was suffering from Polio epidemic when the king of Rock N Roll was leading the charts and was a heart throb for every woman. His debut film was about to release, and he had to appear in "The Ed Sullivan Show" to perform his top songs. He entered, and before the show can start, he rolled up his sleeves to take the polio shot on National television.

Hope the same could be done today for COVID-19 Pandemic.
