“It is our objective to supply as many doses of our COVID-19 vaccine as possible to people in order to help end this pandemic, reduce the hospitalization of especially elderly people and bring us back to our normal lives,” said Ugur Sahin, MD, CEO and Co-founder of BioNTech.

Similarly, the US government has purchased another 100 million doses of Moderna’s COVID-19 vaccine, bringing the order to 300 million doses. To date, the Company has already supplied the US with 41 million doses. According to the Centers for Disease Control and Prevention, 22 million people have received the vaccine.
