WOW: "Covid-19 vaccines... set off a powerful alarm that rallies the human immune system against cancer and nearly doubles the median survival length of patients, according to a new retrospective study by researchers at the University of Texas MD Anderson Cancer Center & the University of Florida."
NEW STUDY PUBLISHED IN NATURE: People who got an mRNA COVID vaccine within ~3 months before or after starting immunotherapy for cancer lived longer overall than those who didn’t get the vaccine.
