A father who almost died a week before his son's first birthday calls on people to be immunized against the flu this winter.
Last winter, Adam Blackman didn't bother to catch the flu and catch the flu.
The virus triggers a life-threatening asthma attack. He spent more than a month in hospital to recover.
He says he "learned the hard way" how dangerous flu is and why people should have the vaccine.
The viruses that cause the flu can mutate and change every year, so you need to get immunized every year to protect yourself.
Mr Blackman, 47, of East Sussex, says he has grossly underestimated how risky a flu can be.
While many who catch it will recover within a week or more, the flu can be deadly to others, especially those at risk.

Asthma United Kingdom says colds and flu are the most common causes of asthma.
In Mr Blackman's case, pneumonia and collapsed lungs meant that he had to be put in a coma for one week in hospital.
"I have asthma and my body just can't handle it," he
"I actually thought I would die before the ambulance got here.
" It was almost catastrophic for me, but my friends and family I was also at risk.
"My son-in-law who has asthma fell ill shortly afterwards and ended up in hospital.
" I learned the hard way to make the flu life-threatening.
"I was hooked up to a life support machine and put in isolation so that the flu does not spread.
"Given how contagious the flu can be, I would urge everyone to get the flu vaccine so they don't have to go through the hell I went through.
"I don't risk it again and I already have the flu vaccine.
"I urge everyone with asthma to get it as soon as possible.
"This could save your life." [1
