A recent publication highlighted on The Focal Points and elsewhere has drawn intense attention by claiming a connection between COVID-19 vaccination and cancer, based on a systematic review that reportedly identifies over 300 peer-reviewed cases and multiple studies in 27 countries showing cancer diagnoses, recurrence, or progression occurring after vaccination or SARS-CoV-2 infection.
According to this review — authored by Charlotte Kuperwasser, PhD, and Wafik S. El-Deiry, MD, PhD in the journal Oncotarget — a global search of scientific literature from January 2020 through October 2025 uncovered 69 peer-reviewed publications including 333 individual cancer cases and large population cohort studies where temporal associations were reported between vaccination and various malignancies across many countries. These covered different cancer types such as lymphomas, carcinomas, sarcomas, melanoma, glioma, and leukemia, with lymphoid malignancies frequently represented among post-vaccination reports.
The review also noted patterns in timing, with roughly half of the reported cases occurring within two to four weeks of vaccination, and some reported within days or continuing over several months after doses or booster shots — timelines interpreted by the authors as potentially consistent with tumor promotion or immune modulation rather than background coincidence alone.
Beyond individual case reports and series, the review identified large population-level studies — including analyses from Korea (≈8.4 million individuals) and Italy (≈300 000 people) — which in the authors' view support a cancer risk signal among vaccinated populations across age and sex groups when compared with baseline rates.
Authors of the review proposed biological mechanisms that might explain observed patterns, including immune dysregulation and reduced tumour surveillance, prolonged exposure to spike protein, and concerns about residual DNA fragments in vaccine formulations that could, in theory, influence cell biology or genomic stability.
These findings have been framed by some commentators as evidence that regulators and health authorities have overlooked cancer risk in post-vaccination safety evaluations, and have raised concerns about journal access being disrupted by alleged cyberattacks — claims that are also part of the broader narrative around this paper's release.
Despite this, public health agencies and major cancer research institutions state that there is no established causal link between COVID-19 vaccines and cancer. Both the National Cancer Institute and organizations such as the American Cancer Society maintain that existing evidence does not show vaccines cause cancer, lead to recurrence, or promote disease progression. Much the same was said by the medical establishment about smoking in the pre-WWII era, with doctors appearing in cigarette advertisements:
