Story summary

A study of over 1,000 patients at MD Anderson Cancer Center found that COVID-19 mRNA vaccination within 100 days of starting immunotherapy correlated with longer survival.
For lung cancer patients, median survival rose from 20.6 to 37.3 months with vaccination.
For melanoma patients, vaccination left many participants still alive at study end, so median survival could not be calculated.
A larger clinical trial is planned to confirm these findings.
