Researchers found many factors within COVID-19 vaccinations that predisposed cancer patients towards a worsening of their condition.

COVID-19 vaccines can trigger genetic changes in cancer patients that could aid in the further development of the disease in such individuals, according to a recent peer-reviewed analysis.
The review, published in the Cureus medical journal on Dec. 17, looked at the relationship between COVID-19 vaccines and cancer. A review of multiple studies led the authors to conclude that certain COVID-19 vaccines may create an environment that predisposes some cancer patients, including survivors, to “cancer progression, recurrence, and/or metastasis.”
The conclusion was based on two factors. First is the “multi-hit hypothesis” of cancer, which suggests that cancer is the consequence of several genetic mutations.
The second is the “growing evidence and safety reports” in the Vaccine Adverse Effects Report System (VAERS), which suggested that some cancer patients who took COVID-19 vaccines saw their conditions worsen.
“In light of the above and because some of these concerns also apply to cancer patients infected with SARS-CoV-2, we encourage the scientific and medical community to urgently evaluate the impact of both COVID-19 and COVID-19 vaccination on cancer biology and tumor registries, adjusting public health recommendations accordingly,” the review said.
The review focused on mRNA vaccines, Pfizer/BioNTech and Moderna, and adenovirus-vectorized vaccines, Johnson & Johnson and Oxford/AstraZeneca, as these products were most widely used in global COVID-19 vaccination campaigns.
