Children from the ages of 6 months to less than 12 year old have now been given their first dose of the Moderna vaccine as part of the company's safety and effectiveness study.
The children participating in the study will be given two injections 28 days apart of either the Moderna vaccine or a saline placebo.
There will be three different possible doses from 25 micrograms up to 100 micrograms that will be given to the children who received Moderna.
The plan is to enroll about 6,750 children from both the U.S. and Canada, and which will be taking place at sites in at least eight states, including Arizona and California to South Carolina and Texas.
