Ivermectin, originally known for its antiparasitic properties, has entered discussions as a potential treatment for cancer, including those cases that some claim have been exacerbated by the COVID-19 vaccine. Research from institutions like City of Hope has highlighted ivermectin's capability to target cancer through inducing apoptosis, inhibiting cell proliferation, and reversing multidrug resistance in various cancer cells, which could theoretically apply to cancers that have purportedly increased in incidence or severity post-vaccination. However, it's crucial to note that there is no scientific consensus or substantial evidence directly linking COVID-19 vaccines to an increase in cancer rates or severity; such claims are often rooted in misinformation or lack rigorous scientific backing.
 

The narrative around ivermectin includes its potential to combat a broad spectrum of cancers by leveraging its anti-inflammatory and anti-proliferative effects. Some proponents on social media and alternative health platforms have suggested that ivermectin could serve as a countermeasure against what they term "vaccine-induced turbo cancers," although this is not supported by peer-reviewed research. Anecdotal testimonials, often shared in these circles, claim dramatic recoveries or stabilization of cancer progression following ivermectin use, but these accounts are not backed by clinical data. The medical community remains cautious, emphasizing that while ivermectin might show promise in lab settings, its application for cancer treatment, especially in the context of post-vaccination cancer, requires extensive clinical validation.
 

The interest in ivermectin as a cancer treatment is part of a larger trend in drug repurposing, where existing medications are explored for new uses. However, the leap from laboratory findings to human application involves numerous challenges, including determining efficacy, safety, and optimal dosing in the context of cancer exacerbated by other factors like vaccines, for which there's no scientific evidence. Researchers advocate for rigorous clinical trials to explore these possibilities, warning against the self-administration of ivermectin, particularly in its veterinary forms like "horse paste," due to potential toxicity and lack of medical oversight. Until definitive clinical evidence is established, the use of ivermectin for cancer, particularly in relation to post-COVID-19 vaccine scenarios, should be approached with skepticism and under strict medical guidance.
