Nearly 100 students received a diluted amount of the Pfizer vaccine at a clinic held on Wednesday, Nov. 10, at South Lake Elementary School in Montgomery Village, Maryland.
Parents were notified by phone Monday night of the mix-up, according to a Montgomery County government news release. An additional clinic will be held at the school next Wednesday, Nov. 17, for the affected children to get an additional dose. Children who can’t attend that clinic are being advised to schedule another appointment at their earliest convenience.
The Montgomery County Department of Health and Human Services learned on Saturday that the affected children received an amount of Pfizer’s pediatric vaccine that was more diluted than recommended.
“We apologize for the error, and we are offering another opportunity for the children to be revaccinated,” James Bridgers, acting county health officer, said in the news release.
“We are confident that this is an isolated situation and staff have already received additional training on reconstituting and administering pediatric doses,” he said.
“Staff will continue to receive weekly updates on clinical guidance for the administration of vaccine doses to this age group.”
A similar incident happened last week when about 100 children received a potentially lower-than-recommended dose of the COVID-19 vaccine at a pharmacy in Loudoun County, Virginia.
