A young ER nurse who questioned the safety of vaccines has died of complications from COVID-19.
Olivia Guidry, from Lafayette in the US state of Louisiana, died after battling the virus in the intensive care unit for only days, friends say.
On July 8, the nurse's sister wrote on Facebook she had a really high fever and a seizure after being diagnosed with Covid several days earlier.
Fluid was later found on her brain and she was put in a medically-induced coma so doctors could attempt to remove it.

"She had an MRI come back showing brain damage and swelling," Brittany Smith wrote.
Her condition continued to deteriorate and on Sunday (local time), her sister posted a message saying Ms Guidry had died.
"My sweet girl, there are so many things that I could say but my heart simply cannot find the words," she said.
"I will miss you every day for the rest of my life ... A beautiful, smart, kind, and loving girl with so much life left to live and who lived life with such joy and vibrancy.
"You were my absolute best friend. I truly can’t imagine life without you ... We will see each other again one day, but right now my heart is so shattered."
Facebook was flooded with tributes from heartbroken friends and colleagues who described Ms Guidry, a nurse at Ochsner Lafayette General, as "devoted and hardworking".
"Hearing this news is soul-crushing. I remember you as a nurse tech in the ER and then starting your nursing career with us all," a colleague wrote.
"You were a joy to be around. To know you is to love you."
Another friend shared her disbelief over the devastating news.
"Please pray for her soul and her family and former ER family as they have no choice but to keep moving amid this horrifically tragic loss at the hands of none other than f***ing Covid," she wrote.
"She's not just a number. She's not a statistic. She is a bright, shiny, hilarious, driven, warm person who loved life ... she was a damn good ER nurse, she worked just like a veteran nurse.
"I feel sick. So incredibly sad. I'm angry, and I am in disbelief. This one hits really hard."
On Friday (local time), Louisiana reported almost 1000 new cases of coronavirus and 10 deaths.
Since the start of the pandemic the state has recorded almost 490,000 total cases and more than 10,000 deaths.
State health officer Dr Joseph Kanter told WWNO radio the number of cases and hospitalisations in Louisiana were going up, with the Delta variant now the dominant strain.
“It’s clear right now that Covid is increasing in the state," he said.
“It’s difficult for us to know how bad it’s going to get.”
Dr Kanter added the vaccines were effective against the Delta variant, however most people in Louisiana are not yet vaccinated and are at greater risk of spreading the virus.
