California public health officials said Monday that people who received a coronavirus vaccine at the Oakland Coliseum on Feb. 28 and March 1 are likely to receive less than what the Centers for Disease Control & Prevention recommends for a single dose – which was confirmed what a TV station last reported last week.
The California Department of Public Health notified people who received a Pfizer COVID-19 vaccine after 1:30 p.m. on Feb. 28 between February 8 and 3:00 p.m. was determined using CDC vaccine. experts.
About 6,300 individuals scheduled appointments during that period that could be ‘influenced,’ said Ali Bay, a spokesman for the Department of Public Health.
The letter from the state health department appears to be undermining statements by government officials who run the Coliseum site in response to inquiries about the overdose. Last week, clinic management officials denied that anyone at the Colosseum had received too little vaccination.
State health officials found that some individuals may have received a dose containing about 0.22-0.3 milliliters per piece, instead of the recommended 0.3 ml Pfizer COVID vaccine. However, the CDC said that any dose greater than 0.15 ml was’ safe ‘and that the dose should not be repeated to protect people from COVID-19,’ the letter reads.
Bay said staff at the Coliseum site corrected the dose difference on March 1st.
“The California Department of Public Health has implemented additional steps for training and quality assurance as a preventative measure,” state officials said.
The letter comes days after KTVU reported that two unnamed medical emergency technicians said that about 4,300 people who were vaccinated at the Oakland Coliseum on March 1 before 2pm “had received the wrong doses.” The syringes have residual vaccine in the bottom of the container.
