(CNN)Vaccine maker Pfizer said Friday that trials of its vaccine in children ages 2 to 5 show that it did not provide the expected immunity in kids this age, and it is adding a third dose to the regimen.
The company decided to add the third dose for all children and babies ages 6 months to 5 years after its independent outside advisers took a look at the data so far.
It showed that two child-sized doses of the Pfizer/BioNtech vaccine were not producing the expected immunity in the 2- to 5-year-olds, although they were doing so for the babies up to age 2.
So the company said it would "amend" the trial to add a third dose.
