Dr. Joseph Ladapo again raised concerns about the delivery of "nucleic acid contaminants" in the vaccines and the "risk of DNA integration" into cells. And again, the FDA stood behind the science.

Adult doses got shipped first, CDC director Mandy Cohen said. Doses for the under-12 set have begun shipping, and “the supply is filling out.”

CEO Stephane Bancel said Moderna gave the government a discount with its initial prices. Now, the company must assume more costs and risk, he said.

Once U.S. stockpiles of COVID-19 vaccine run out, Moderna says it might charge as much as $130 per dose, but give people who lack health insurance a break. Critics say that's not enough help.

The drugmakers said a combination of the vaccine and Merck’s immunotherapy Keytruda led to a statistically significant improvement in survival before the cancer returned in patients with advanced melanoma.

Moderna CEO Stephane Bancel said in a prepared statement that the vaccine developer pioneered that technology and invested billions of dollars in creating it.

Advisers to the CDC voted unanimously to recommend Moderna's shots as an option for school-age kids and adolescents. This age group has been able to get shots shots made by Pfizer since last year.

The consensus has been that Pfizer and Moderna are most protective. But a study looking at 5 vaccines — including Russia's Sputnik V and two Chinese types — offers an unexpected finding.

The vaccine maker’s COVID-19 shots, which are now available in more than 70 countries, totaled $17.7 billion in sales last year, their first full year on the market.
