(Reuters) - Moderna (NASDAQ:MRNA) Inc said on Thursday it expects COVID-19 vaccine sales of $18.4 billion this year, above the $15 billion in sales forecast by Pfizer Inc (NYSE:PFE) for the only other vaccine authorized for emergency use in the United States so far.
Both vaccines, developed using a technology based on messenger RNA (mRNA), are being distributed at an unprecedented speed as cases mount in the United States, with deaths from COVID-19 surpassing the dire milestone of 500,000.
Moderna, whose shares rose 4% to $150.7 in trading before the bell, has been aiming to ramp up production of the vaccine, its first and only revenue-generating product.
It now aims to produce at least 700 million doses this year and expects to raise production to as much as 1 billion doses by improving its manufacturing process..
"2020 demonstrated the power of harnessing mRNA to make medicines," Chief Executive Officer Stéphane Bancel said in a statement.
"I believe that 2021 will be an inflection year for Moderna."
Moderna expects cost of sales to be about 20% of product sales in 2021, well above the 4% it recorded a year earlier.
The company also said it had completed enrollment for a mid-to-late stage study of the vaccine in adolescents between the ages of 12 and 17, while a study in children aged six months to 11 years will start in the near-term.
Moderna's chief medical officer, Tal Zaks, would leave the company in late September, the company added.
