BACKGROUND: Immune checkpoint inhibiting antibodies were introduced into routine
clinical practice for cancer patients. Checkpoint blockade has led to durable
remissions in some patients, but may also induce immune-related adverse events
(irAEs). Lung cancer patients show an increased risk for complications, when
infected with influenza viruses. Therefore, vaccination is recommended. However,
the efficacy and safety of influenza vaccination during checkpoint blockade and
its influence on irAEs is unclear. Similarly, the influence of vaccinations on T
cell-mediated immune reactions in patients during PD-1 blockade remains poorly
defined. METHODS: We vaccinated 23 lung cancer patients and 11 age-matched
healthy controls using a trivalent inactivated influenza vaccine to investigate
vaccine-induced immunity and safety during checkpoint blockade. RESULTS: We did
not observe significant differences between patients and healthy controls in
vaccine-induced antibody titers against all three viral antigens. Influenza
vaccination resulted in protective titers in more than 60% of
patients/participants. In cancer patients, the post-vaccine frequency of irAEs
was 52.2% with a median time to occurrence of 3.2 months after vaccination. Six
of 23 patients (26.1%) showed severe grade 3/4 irAEs. This frequency of irAEs
might be higher than the rate previously published in the literature and the rate
observed in a non-study population at our institution (all grades 25.5%, grade
3/4 9.8%). CONCLUSIONS: Although this is a non-randomized trial with a limited
number of patients, the increased rate of immunological toxicity is concerning.
This finding should be studied in a larger patient population.
