ANTIOCH, Calif. (KRON) — Several children in Antioch were administered the wrong dose of the COVID-19 vaccine, Sutter Health confirmed.
It happened over the weekend.
“14 patients at our Antioch pediatric vaccine clinic received vaccines with an incorrect amount of diluent. As soon as we learned of this, we contacted the parents and advised them of CDC guidance in this situation. The safety of our patients is our top priority, and we immediately reviewed our processes to help make sure this doesn’t happen again,” said Dr. Jimmy Hu, Chair of the Sutter Health COVID-19 Vaccine Task Force and Pediatrician.
Patients who receive an incorrect diluent volume may experience more arm soreness, fatigue, headache or a fever, Hu adds, citing the CDC.
A diluent is a normal, preservative-free saline (0.9% sodium chloride) that is mixed with the vaccine.
It comes in a separate vial from the vaccine, and medical officials are supposed to prepare each dose with a new vial of diluent and a new vial of vaccine each time, according to the CDC’s Pfizer vaccine preparation guide.
For kids ages 5-11 years old, the vaccine is supposed to include 1.3 mL of diluent, according to the CDC. This age group’s diluent dose comes with an orange cap to differentiate from the diluents for people 12 years and up.
Sutter Health refused to clarify whether the children were given extra diluent or less diluent. KRON4’s Sara Stinson has reached out to a parent of a child given the incorrect dose.
If a child was given less diluent, they should not repeat the dose and their parent or guardian should be made aware of potential side effects. If the child was given extra diluent, then the vaccine administrator should repeat the dose immediately, according to the CDC.
