When the federal government no longer buys vaccines at a discount for the entire nation, individual health-care providers will purchase the shots from the vaccine makers at a higher price. Moderna CEO Stephane Bancel told CNBC last month that the company is preparing to sell the vaccines on the private market as early as this fall. Pfizer CEO Albert Bourla told investors during the company's earnings call this week that he is preparing for the vaccines to go commercial in the second half of the year. Pfizer and Moderna have said they are considering hiking the price of the vaccines to somewhere around $110 to $130 per dose once the U.S. government pulls out of the vaccine program.
