I contracted the flu on the way back from Africa during Christmas and the doc I saw upon my return said I would have probably been on a ventilator if I hadn’t had all the flu shots...
“and the doc I saw upon my return said I would have probably been on a ventilator if I hadn’t had all the flu shots...”
Anecdotal: I used to get flu shots yearly in the Army, and later the VA. Then I went to Iraq for 4 years and didn’t get them. When I came back I would get sick and even pneumonia every year. I started getting the flu shots again and after six years of yearly flu shots rarely got sick. Haven’t had pneumonia since 2013 either.
