Clinical trial underway to help determine right vaccine dose for children

A clinical trial is underway at Children’s Mercy Hospital to determine the correct dose of COVID-19 vaccine for children.

Dr. Barbara Pahud said the phase 1 clinical trial was started about two weeks ago for children 6 months to 11 years old. The trial will determine if children should get a different sized dose than adults.

Dr. Pahud is research director of pediatrics infectious diseases at Children’s Mercy Hospital and clinical associate professor of pediatrics at the KU School of Medicine. She spoke at the University of Kansas Health System news conference Friday morning.

They are trying to find a vaccine dose for children that is immunogenic and does not have many side effects, she said.

They are still enrolling children in the phase 1 study, according to Dr. Pahud, and they are close to finding the correct dose for children. About six places in the world are running phase 1 clinical trials for children, she said.

As soon as these six centers find the correct dose for children, that dose will get locked in, and then they will begin doing the clinical trials that have been seen everywhere around the world for adults.

They will enroll more children in the trials at that point, she said.

Dr. Pahud said that quite often, vaccines given to children are in smaller doses than those given to adults. For example, the varicella vaccine for children is a much smaller dose than the zoster vaccine given to adults, she said. The vaccine protects children from getting varicella. Once people get varicella, they can get it again as an adult as zoster or shingles, she said.

Dr. Pahud said Pfizer has already finished acquiring the data they need to submit to the FDA for the emergency use authorization for the COVID-19 vaccine for children 12 and older. The FDA is busy reviewing the data for the Johnson and Johnson vaccine, and as soon as it is completed, they will be able to review the data for the vaccine for children over 12.

The study currently underway at Children’s Mercy is for 6 months to 11 years old, and the major trial hasn’t started yet, Dr. Pahud said.

“At Children’s Mercy, we are trying to make uncomfortable situations as comfortable as we can,” Dr. Pahud said.

They will be given numbing agents to the children before they get blood draws, she said. However, it’s possible some children may be upset not because they are hurting but because they are afraid, she said.

On another topic, Dr. Dana Hawkinson, medical director of infection prevention and control at KU Health System, said studies have shown that the risks are much greater of not getting the COVID-19 vaccine than getting the vaccine. Those who get the disease have a higher risk of medical complications than those who get the vaccine. Data coming out recently showed the vaccine is safe for pregnancy.

Dr. Hawkinson said about 20 percent (or one out of five) of the people who get COVID-19 get blood clots in their legs or lungs. The risk shown in the Johnson and Johnson vaccine for blood clots in the brain was about one in a million, he said.

New data has shown the risk of mortality increases in the six months following getting COVID-19 because of the long hauler syndrome, he said.

“There’s a risk-benefit in everything we do,” Dr. Pahud said. Even Tylenol, an over-the-counter medication, can cause liver failure in a very small number of people, she said. People just need to weigh the benefits versus the risks, she said.

Dr. Hawkinson said they have seen an overwhelming benefit from getting these vaccines.
