Brief summary

The LLS COVID-19 Registry is being amended to invite people who participated in the LLS COVID-19 Registry and did not develop antibodies after receiving a complete COVID-19 vaccination, as well as people with blood cancer who did not participate in the initial LLS COVID-19 Registry and also did not develop antibodies after receiving a complete COVID-19 vaccination, to participate in this amended LLS COVID-19 Registry.

Detailed description

The results of the Leukemia and Lymphoma Society (LLS) COVID-19 Registry indicate that about twenty-five percent (25%) of people with blood cancer and on immunosuppressants participating in the LLS COVID-19 Registry, who received a complete COVID-19 vaccination, did not develop antibodies. The Food and Drug Administration has authorized third doses (boosters) of the Pfizer and Moderna Covid-19 vaccines for people with weakened immune systems, in a bid to bolster their protection against infection as the highly contagious Delta variant circulates. The agency will amend the emergency-use authorizations for the two vaccines to allow immunocompromised people to get an additional dose. Therefore the LLS COVID-19 Registry is being amended to invite people who participated in the LLS COVID-19 Registry and did not develop antibodies as noted above, as well as people with blood cancer who did not participate in the initial LLS COVID-19 Registry and also did not develop antibodies after receiving a complete COVID-19 vaccination, to participate in this amended LLS COVID-19 Registry. Using the same design as the initial COVID-19 Registry (Protocol LLSC19-001), this amended LLS COVID-19 Registry will determine if people who have decided to receive a booster vaccination, who did not develop antibodies after receiving a complete COVID-19 vaccination will develop antibodies after a single dose booster of either the Pfizer or Moderna COVID-19 vaccination.
