The meetings are a sign that the vaccines are moving closer to a possible authorization.
During the winter omicron wave, children under age 5 were hospitalized with Covid at five times the rate of the peak when the delta variant was predominant, according to the Centers for Disease Control and Prevention. About 75% of children in the U.S. have been infected by the virus at some point during the pandemic, according to data from national blood sample survey from the CDC.
Novavax was an early participant in Operation Warp Speed, the U.S. government's race to develop a vaccine against Covid in 2020. However, Moderna and Pfizer ultimately beat Novavax to the punch because the company struggled with manufacturing issues. Novavax produces the virus spike outside the human body. The genetic code for the spike is put into a baculovirus that infects insect cells, which then produce copies of the spike that are purified and extracted for the shots. The vaccine also uses an adjuvant, an extract purified from the bark of a tree in South America, to induce a broader immune response.
