Pfizer said Friday it’s going to test three doses of its COVID vaccine in young children under five years old, after two jabs failed to produce the expected immunity in babies and preschoolers.
Two doses didn’t appear strong enough in some of the kids, the company said, saying that a preliminary analysis found 2- to 4-year-olds’ immune response wasn’t as strong as expected to the lose-dose jabs for younger children.
If three doses proves successful, Pfizer and its partner BioNTech said they would apply for emergency authorization sometime in the first half of 2022.
The company already has a ‘kid-sized’ vaccine for 5- to 11-year-olds, which is one-third the dosage given to adults and children 12 and older.
For someone younger than 5, the company has been testing a very small dose: 3 micrograms, or one-tenth the amount an adult receives in their jab.
The news is a setback and comes as COVID cases are spiking in the U.S. and the Omicron variant is spreading nationwide, with 39 states now having detected cases as of late Friday, according to Centers for Disease Control and Prevention (CDC).
Cases are up 31 percent nationwide over the past two weeks, with 124,413 people testing positive for the virus. Deaths have increased by 28 percent over the past two weeks as well, with 1,288 people dying every day.
The Omicron variant, which was first discovered last month in South Africa, is taking hold in the U.S., as well.
