NEW YORK (WABC) -- There's a new step towards vaccinating children against COVID, a trial involving babies and young children is underway.
Pfizer says its vaccine is now being tested on children as young as six months old.
"When we weigh the risk with getting the virus, it's clear, let's get the vaccine," said Otavio Good, father.
The California couple's seven-month-old son will take part in the trial this week.
His 1-year-old brother was the first in his age group to start the trial.
"He had a sore arm for a day, was a little low energy for a day, but that's it," said Zinaida Good, mother.
In the meantime, the CDC says more than 50% of adults have received at least one dose of the COVID vaccine.

How many people in your area are hesitant to get the COVID-19 vaccine?
Most states have opened up COVID-19 vaccination to everyone 16 and older, but not everyone is lining up to get the shot. With the recent temporary pause on the distribution of the Johnson & Johnson vaccine, doctors worry about an increase in vaccine hesitancy that may not be warranted. Using data from the U.S. Census Bureau's Household Pulse Survey, the CDC found that as many as a third of adults in some areas reported being hesitant about getting the COVID-19 vaccine. These rates are highest in the states of Wyoming and North Dakota, and lowest in Massachusetts, Vermont and California.
