Researchers at Winship Cancer Institute of Emory University found that COVID-19 vaccines are much less effective for patients with non-Hodgkin lymphoma and chronic lymphocytic leukemia, particularly those ages 65 and older. After vaccination, many of these patients produced low or no antibodies that bind or neutralize SARS-CoV-2 and its variants of concern, particularly Omicron.
Treatment with an indefinite course of osimertinib dramatically improves progression-free survival for patients with stage 3 non-small cell cancer, according to the results of the LAURA trial. The median PFS was 39.1 months in the osimertinib group, compared to 5.6 months with the placebo group.
