covid vaccines may increase the life span in cancer patients

Question

the article by the gaurdian talks about how a study being done has been showing that the mRNA vaccines actually help maligment cells.

Answer 1

The article used in the claim talks about how it is true that Covid vaccines have helped cancer patients live longer. Over half (55.7%) of vaccinated patients were alive compared to the unvaccinated patients in which only 30.7% were still alive after 3 years since starting treatment. Scientists found that pairing an mRNA vaccine with immunotherapy  helped active the immune system. It doesn't target just cancer, but it primes the immune system to be more responsive and alert.

I did further research on this topic and found an article by UFHealth that confirms this is true. They also did a study on this and found that receiving a Covid mRNA vaccine within 100 days of starting immunotherapy increased the life of cancer patients significantly.

Answer 2

The claim that covid vaccines may increase the life span in cancer patients according to The Guardian. "According to an a recent study published in Nature, mRNA vaccines seem to trigger a powerful immune response that increases the median survival time by about 75% for certain cancer patients" (The Guardian). In this text The Guardian uses statistics to describe how covid vaccines may increase the lifespan of cancer patients. The mRNA vaccines activate the immune system in general, which fights cancerous cells. The Guardian is a credible British daily newspaper, known for its independent and investigative journalism. Another site that reported on this claim was UF Health, the official webpage for the academic health center in Florida. "The results from this study demonstrate how powerful mRNA medicines truly are and that they are revolutionizing our treatment of cancer" (UF Health).

Therefore, the claim that covid vaccines may increase the life span in cancer patients is backed by multiple sources such as The Guardian and UF Health, which supports this with statistical evidence.

Answer 3

This claim appears to be true. In a study, patients who were vaccinated lived a median of 37.3 months, compared to the unvaccinated group who lived a median of 20.6 months. On top of this, after three years of treatment, the vaccinated group had a 20% higher survival rate than the unvaccinated group. The way in which this works is that the vaccine basically puts the body's immune system on high alert to be able to recognize and attack cancerous cells, "the cancer cells start making the immune checkpoint protein PD-L1, which works as a defense mechanism against immune cells. Fortunately, several immune checkpoint inhibitors are designed to block PD-L1, creating a perfect environment for these treatments to unleash the immune system against cancer." (MDAnderson) In short, the vaccine itself doesn't fight the cancer, but it allows the immune system in the body to target the cancer.

Answer 4

The Guardian asserts that COVID vaccinations may lengthen cancer patients' lives. "According to an a recent study published in Nature, mRNA vaccines seem to trigger a powerful immune response that increases the median survival time by about 75% for certain cancer patients" . The Guardian utilizes statistics in this article to explain how COVID vaccinations may lengthen cancer patients' lives. The mRNA vaccines stimulate the immune system as a whole, which combats malignant cells. The Guardian is renowned for its independent and investigative reporting. The official website of the academic health center in Florida, UF Health, also reported on this assertion, "The results from this study demonstrate how powerful mRNA medicines truly are and that they are revolutionizing our treatment of cancer".

Therefore, a number of publications, including The Guardian and UF Health, provide statistical evidence to support the idea that COVID vaccinations may lengthen the lives of cancer patients.
