People who received a Pfizer vaccination dose on Feb. 28 after 4:30 p.m. and March 1 between 8 a.m. and 3 p.m. may have received the slightly smaller doses, the CDPH said in a statement.

The recommended dose of the vaccine by the CDC is 0.3 milliliters, but dosages of 0.15 milliliters or more are still sufficient and the recipient does not need to repeat the dose, the CDPH said.
The affected vaccine recipients at the Colosseum may have received dosages of 0.22 milliliters, “which is well within the range set forth by the CDC,” the CDPH said in a statement.
On-site personnel at the vaccine site, which is jointly managed by the California Office of Emergency Services and the Federal Emergency Management Agency, corrected the dosage difference on March 1, according to the CDPH.

People who received their first dose during the affected period on February 28 and March 1 should still receive their second dose about three weeks after the first was administered.
CDPH officials also sent a letter to those receiving the slightly smaller doses, notifying them of the dosage difference and reminding them of the two-dose schedule of the vaccine.
People with questions about the COVID-19 vaccine dose they have received can contact the CDPH at [email protected] or by calling (833) 422-4255.
