The Department of Public Health is recommending that 585 people get revaccinated


COLORADO. (KRDO) -- The Colorado Department of Public Health and Environment (CDPHE), in consultation with Moderna, is recommending that 585 patients who received the Moderna COVID-19 vaccine between September 2021 and May 2022 by Denver-based Bloom Healthcare be revaccinated because they administered vaccines past their beyond-use date.

Bloom Healthcare self-reported this vaccine handling and administration error to CDPHE and is contacting those affected and for whom contact information is available via phone and email.

The CDPHE temporarily paused Bloom Healthcare from administering and reordering COVID-19 vaccine but recently reauthorized their approval so they can coordinate repeat doses for those who need to be revaccinated. The majority of COVID-19 vaccine doses administered by Bloom Healthcare are not affected.

The CDPHE is working closely with Bloom Healthcare to ensure every effort is made to contact the people affected. CDPHE is also requiring Bloom to complete a COVID-19 vaccine compliance improvement plan to ensure similar administration errors do not occur again.

The CDPHE says that vaccines administered past their beyond-use date may be ineffective, and CDC and CDPHE believe revaccination is appropriate.

There are no negative side effects associated with receiving a dose of a COVID-19 vaccine past its beyond-use date. The only risk is that it may not offer protection from COVID-19 the way a valid dose does, and the efficacy of the doses administered cannot be confirmed, according to the CDPHE.

People who received the Moderna COVID-19 vaccine through Bloom Healthcare between September 2021 and May 2022 can email CDPHE with questions at They can also call the COVID-19 vaccine call center at 1-877-268-2926, available Monday through Friday, 8 a.m. to 8 p.m.; Saturday and Sunday, 9 a.m. to 6 p.m. MT, and answers are available in multiple languages.

If anyone witnesses what they believe to be irregular vaccination practices, the CDPHE encourages them to file a complaint using our online complaint form, or they can call 1-877-268-2926. Anyone with knowledge or concerns about an enrolled COVID-19 vaccine provider can file a complaint says the CDPHE.
