US pharmaceutical giant Moderna on Monday reported a "robust neutralizing antibody response" to its Covid vaccine in children aged 6-11, and said that it will submit the trial data to global regulators soon.
"We are encouraged by the immunogenicity and safety profile of mRNA-1273 in children aged 6 to under 12 years and are pleased that the study met its primary immunogenicity endpoints," chief executive Stephane Bancel said in a statement.
The results come after Pfizer said last week that its Covid vaccine was 90 percent effective in preventing symptomatic disease among children aged 5-to-11.
The Food and Drug Administration has called an advisory panel of independent experts to meet Tuesday to vote on whether to green light Pfizer's shot.
Overall, more than 150 children aged 5 to 11 have died from Covid in the United States since the start of the pandemic, according to official data.
The administration of President Joe Biden has said it stands ready to roll out shots for the country's 28 million 5 to 11-year-olds as soon as a vaccine is authorized by science agencies.
