Luis Pitarma, 29 and Jenny McGee, 35, watched over him for 48 hours in intensive care, giving him vital oxygen.
He thanked the ” indomitable ” medics at London’s St Thomas’ Hospital in an emotional video message after he was released from hospital following a 7-day battle with the killer bug.
The PM said: “The NHS saved my life. No question. Things could have gone either way.”
Boris said of Jenny and Luis: “The reason, in the end, my body did start to get enough oxygen was because for every second of the night they were watching and they were thinking and they were caring and making the interventions I needed.”
Mr. Johnson will now spend time recovering at Chequers, the PM’s country home, for at least the next week.
Jenny’s brother Rob McGee hailed his sister and NHS staff as she returned to work last night.
He told BBC “She is very humble and is back at work now for another night shift.
“She said she was just really pleased to see all the hard-working people in the NHS be recognized for the amazing work they are doing.”
Mr. McGee added: “She is just doing her job, and that is how she sees it.
“This is what she was trained for, helping people who need care. [Medics are] special people.”
The nurse, of Invercargill, New Zealand and has been in Britain for eight years, trained in intensive care at the Royal Melbourne Hospital in Australia where she worked for six years.
Her other sibling Michael said her entire Kiwi family is delighted with the 35-year-old being singled out by Boris.
“We are all very proud of Jen, and to get acknowledged by Boris is something else.” Read Here
