Maribel Duarte told KNBC-TV that her son was bribed with pizza and told not to tell her about it by an official at the Barack Obama Global Prep Academy in South Los Angeles.

"The lady that gave him the shot and signed the paper told my son, 'Please don't say anything. I don't want to get in trouble,'" said Duarte, who showed the outlet a vaccine card indicating that her son accepted it. It indicates that two doses of Pfizer's vaccine was administered, one on Oct. 28, and the other on Nov. 18.

Duarte says she's not anti-vax and is vaccinated herself, but that her son is a special case.

"He has problems with asthma and allergy problems," she said, adding: "It hurt to know he got a shot without my permission, without knowing and without signing any papers for him to get the shot."
