The updated list, which is subject to the approval of the vaccine supply by the Medicines and Health Products Regulatory Agency (MHRA), is divided into nine groups, the elderly living in nursing homes and care home workers being the top priority.
Next come all people aged 80 and over and health and social service workers.
The list decreases by age groups in five year increments.
People aged 70 and over, as well as those who are clinically extremely vulnerable, rank fourth on the priority list.
This means that people with conditions such as blood, bone or lung cancer, chronic kidney disease, and Down syndrome were placed in the priority group four out of nine.
Gemma Peters, Managing Director of the Blood Cancer UK charity, said: “This is very good news.
“Putting people with blood cancer at the same priority level as people over the age of 70 better reflects the fact that they are particularly vulnerable to the coronavirus. ”
She added: “Any vaccine may not work as well in people with blood cancer, so vaccinating those around them is an essential part of their protection.
“We are very grateful to the government for listening to the voices of people with blood cancer and other health issues on this issue.
“It’s also important to remember that this is not definitely the final priority list.
“No vaccine has yet been approved, and we are awaiting confirmation that any vaccine will be safe and effective for people with blood cancer. ”
The clinically vulnerable group excludes pregnant women and those under 18.
The updated list describes the conditions that fall under priority group six for at-risk adults between the ages of 18 and 65.
These include diabetes, chronic heart disease, and morbid obesity.
The risk group was ranked sixth on the priority list and is followed by those aged 60, 55 and 50.
