Covid-19: 'Without the vaccine we would have been on our knees'
BBC News NI is given access to Belfast City Hospital's intensive care unit, where a consultant warns the system is "one step from chaos".
Seven patients had Covid-19 - six of the men and women in their 20s, 40s and early 60s were unvaccinated.
One of them was double-jabbed.
"Without the vaccine we would have been on our knees weeks ago," Dr Gardiner said.
