If you have cancer And you think it’s a coronavirus vaccination You may do a little better, don’t let your hesitation stop you from getting shots: pair Clinical trial It was found that the patient’s immune system was elevated after vaccination.
The findings were presented this week at a virtual conference of the European Medical Society. Oncology (ESMO Congress 2021).
Nearly 800 patients in the Netherlands participated in the VOICE study.It included some and some not cancer, And those who were being treated chemical treatment, Immunotherapy or a combination of the two. They received a two-dose mRNA vaccine from Moderna.
Approximately one month after the second vaccination, researchers found adequate levels of antibody in 84% of patients. chemical treatment93% of people receiving immunotherapy, 89% of people receiving combo chemical treatment/ Immunotherapy.
Passaro said the results were comparable to the high levels of antibody response seen in more than 99% of test participants who did not have them. cancer..
“The high vaccine efficacy observed across the study population, regardless of the type of anticancer treatment, constitutes a powerful and reassuring message for patients and their physicians,” Passaro said in a news release at the conference. rice field.
The study found that two doses were needed to achieve strong immunity in cancer patients. Only one in three patients with chemotherapy or chemotherapy / immunotherapy achieved a sufficient response after the first injection. This is about half of patients without cancer.
Nearly 600 cancer patients in the United Kingdom participated in the CAPTURE trial. They received either the Pfizer-BioNTech or AstraZeneca vaccine twice.
About one-third had a previous contract COVID-19 (New Coronavirus Infection), And the vaccine produced higher levels of virus-neutralizing antibodies in those patients.

Passaro supports the idea that these results require cancer patients and other people with weakened immunity to receive complete vaccine therapy and may require booster immunity for best results. He said.
He pointed to another clinical trial in about 230 cancer patients in Israel. Of these, less than one-third developed antibodies after the first dose of the Pfizer vaccine. Nearly 9 in 10 achieved a proper immune response when they received the second dose.
“The results confirm that our patients need a complete vaccination,” Passaro said. “All our cancer patients COVID-19 (New Coronavirus Infection), Regardless of the type of vaccine. “
Findings presented at medical conferences are considered preliminary until published in a peer-reviewed journal.
