Moderna Inc. executives said on Thursday they believe a fourth COVID-19 vaccine shot will be needed late this year due to waning protection from earlier doses, which could push up sales in the second half of 2022.
Chief Executive Stephane Bancel stressed that the company’s current sales projections for its Spikevax COVID-19 shot—$19 billion in 2022, up from its prior estimate of $18.5 billion—does not include any additional sales to the United States this year.
