A mother is grieving the loss of her 33-year-old daughter who was vaccinated against COVID-19 yet still succumbed to the virus on Sunday, according to a report.

And I am vaccinated.' But when she got to the hospital, turns out she had it," Tara Mosley, Angelle's mother, told WDSU.

She said, 'They will keep me because I have pneumonia and a high fever,'" Tara Mosley told the outlet.

CDC'S NEW MASK GUIDANCE FOR FULLY VACCINATED LEAVES SOME EXPERTS DIVIDED.

Angelle’s story comes as a highly transmissible delta variant, said to account for at least 83% of sequenced samples in the U.S., is behind rising infections nationwide, and even spurred a reversal in federal health guidance relating to mask use. The Centers for Disease Control and Prevention (CDC) now calls for fully vaccinated individuals to don masks in public indoor areas in places with high and substantial viral spread

The CDC reports at least 5,914 breakthrough cases (or infection resulting in hospitalization or death in a fully vaccinated individual), with 27% of hospital admissions reported as asymptomatic or not related to COVID-19, and 26% of deaths reported as asymptomatic or not related to COVID-19 against a backdrop of over 161 million fully vaccinated people in the U.S

Louisiana, where Angelle's death reportedly occurred, is among nearly two dozen states grappling with high levels of viral transmission, where the CDC recommends fully vaccinated individuals wear masks in public indoor areas
