covid19 vaccine

There have been outbreaks throughout the history of man. Even in the bible, we remember when the Egyptians were plagued. Both in this modern time and centuries past, there have been a number of pandemics of diseases such as smallpox and tuberculosis. One of the most devastating pandemics was the Black Death (also known as The Plague), which killed an estimated 75–200 million people in the 14th century. Other notable pandemics include the 1918 influenza pandemic (Spanish flu) and the 2009 flu pandemic (H1N1). Current pandemics include HIV/AIDS and now the 2019–20 coronavirus pandemic.
