Corona Vaccine Protects Blood Cancer Patients: Generally, the immune system of people suffering from blood cancer is very weak. Because of this, they become easy victims of Covid and fall ill soon. In addition, there are many cancer treatments that allow little or no antibody production against SARS-CoV-2 after Covid-19 vaccination in patients. On the other hand, vaccination can activate T cells, which are responsible for long-term immune responses.
Virologist Prof. of the Medical Center of LMU Munich-University of Freiburgand. A team led by Oliver T. Kepler’s Dr. Andrea Kepler-Haffkemeyer and Dr. Christine Greil has shared a detail after studying the immune response of patients for several months. This study was done on those patients who had blood cancer and who had got all the three doses of corona vaccine. The results show that corona vaccination protects these patients from serious diseases caused by SARS-CoV2.
Strong T cell response to Covid-19 vaccination
This study was based on patients with two types of blood cancer – B-cell lymphoma and multiple myeloma. Dr. Andrea Kepler-Hafkemeyer said that the results of this study, conducted on all participants in the study, showed that almost all participants had a strong T cell response to the Kovid-19 vaccination. Dr. Christine Greil says, ‘Symptoms of infection were found to be mild to moderately severe in the people participating in the study, because the antibodies produced after vaccination could not be produced due to therapy. This could be a reason.
Antibodies against different variants of SARS-CoV-2
The study shows that patients who can make antibodies can also produce high quality antibodies. The antibodies produced after the second vaccination neutralize different variants of SARS-CoV-2. This capacity is much higher in these patients as compared to vaccinated people. Covid-19 vaccination can induce antiviral immunity including ‘neutralizing antibodies’ on a very large scale in patients with different types of blood cancers. As a result, multiple vaccine doses can be recommended without interruption for patients with B-cell lymphoma or multiple myeloma.
