Jo Whiley's sister will have her covid vaccination this weekend, a month after she was hospitalised with the virus.
The broadcaster, 55, told listeners of her BBC Radio 2 show that Frances, 53, is scheduled to have her jab in the coming days.
Her younger sister has diabetes and learning difficulties related to rare genetic disorder Cri du Chat.
Frances contracted the killer virus after an outbreak at the care home where she lives, and was so poorly she was admitted to hospital.
While she fought for her life, Jo was offered her covid vaccine, prompting her to slam Government chiefs for not prioritising the more vulnerable members of the population.
At the time, mum-of-four Jo said: "I would give up my vaccine in a heartbeat if I could for my sister and any of the residents in her house to have their vaccine.
"It does not feel right. She's fighting for her life in hospital. It couldn't be crueller."
But finally she had some happier news to share with listeners, telling them last night: "My sister gets her vaccination this weekend
"It's been a long time coming - you have to wait a month after you have had Covid."
When Frances was in hospital, Jo was a guest on This Morning where she revealed her family had discussed "end of life care" for her poorly sister.
Jo said: "It played out like the worst disastrous movie. I got offered my vaccine, which felt like the cruellest twist.
"She refused to take our calls. She refused to talk to me, to my mum and dad. That showed the impact on her mental health."
Due to Jo's actions, vulnerable adults were added to the Government's 'top six' vaccine priority groups.
