It's a plausible enough mistake to have happened before. Which to me, is good enough reason to not outright dismiss it as "obviously false".
Some Polio vaccines were contaminated with SV40 for years, and it does, in fact, alter human DNA.
For COVID-19, there have been at least 2 major cases of live virus vaccine contamination and recall. In the case of the Sputnik vaccine in Brazil and South Africa, there are claims that at least some made it into patients.
And then the "Baltimore Factory" testimony before Congress included company executives admitting to making ~100 million contaminated doses, more than the number of safe doses they had produced.
So this "don't mind him, he does conspiracies" attitude isn't doing anything except getting nods from those that don't need convincing, and proving to skeptics that you have a knowledge gap, whether it's ultimately relevant or true (or not).
I don't think it's currently happening happening here (at a minimum, adenovirus doesn't alter your DNA), but I also think it's just as reckless to imply that any concerns aren't legitimate or that it's impossible.

>>polio vaccine administered from 1955–1963 was contaminated with simian virus 40 (SV40). The virus came from the monkey kidney cell cultures used to produce the vaccine. Most, but not all, of the contamination was in the inactivated polio vaccine (IPV). Once the contamination was recognized, steps were taken to eliminate it from future vaccines. There have been many questions as to the effects on people who received the contaminated vaccine. SV40 has biological properties consistent with a cancer-causing virus, but researchers have not conclusively established whether or not it could cause cancer in humans. Studies of groups of people who received polio vaccine during 1955–1963 provide evidence of no increased cancer risk.
>>However, because these epidemiologic studies are sufficiently flawed, the Institute of Medicine's Immunization Safety Review Committee concluded that the evidence was inadequate to conclude whether or not the contaminated polio vaccine caused cancer. In light of the biological evidence supporting the theory that SV40-contamination of polio vaccines could contribute to human cancers, the committee recommends continued public health attention in the form of policy analysis, communication, and targeted biological research.
"Based on these limitations, the committee concludes that the evidence is inadequate to accept or reject a causal relationship between SV40-containing polio vaccines and cancer."
There is literally no reason to bring this up in relation to COVID vaccines. First, this was a contamination issue with polio vaccines between 1955 and 1961, long since fixed (and unlikely to happen again, as it is now much easier to detect this kind of contamination). Second, there has never been any good evidence that the 'contaminated' vaccines ever did anyone any harm.

Multiple vaccines have already been recalled due to contamination, after they passed initial qaqc.
How does that make it unlikely that contaminated products don't go undetected?
My point isn't that vaccine's shouldn't be taken.
It's that the same people that constantly complain about pharmaceutical companies taking shortcuts and behaving unethically, suddenly decide the same companies are infallible when it comes to a rushed development of a product, from which they are fully shielded from liability.
>There is literally no reason to bring this up in relation to COVID vaccines
When someone suggests a concern is scifi conspiracy theory nonsense, and that concern has actually historically happened, then it's absolutely relevant.
The scare tactics are bad enough, but don't try to trick people with lies and outright manipulation, and there won't be anything to call out.

Come on – this is just the standard ass-covering language in a scientific paper. "Further research is needed." By the nature of the case it's very hard to conclusively show that no-one has ever had a cancer caused by a 1960s Polio vaccine. But at present there is no good evidence that this has happened, as the paper that you linked to states very clearly.
Any medication can contain contaminants. I do not understand why you think that the mere abstract possibility that any given vaccine might contain contaminants is relevant to COVID vaccination efforts. This is like cautioning against people taking Aspirin because any given Aspirin pill might contain contaminants.
You posted a lot of evidence that SV40, a virus, causes cancer. You are using that to argue against a vaccine that targets a virus (the COVID-19 vaccine), because that vaccine might be contaminated with a virus? This is absolutely ridiculous. Viruses cause cancer, not vaccines.

Right, and the Harvard Mark II had a moth that caused it to malfunction, therefore we can't trust the Apple M1.
This is the level of reasoning that anti-vaxers have sunk to. It's deliberate ignorance and sophistry.
Anti-vaxers aren't "asking questions". They aren't curious about actual reality. They are very confused people who want to maintain a simplistic (maybe naturalistic, who knows?) worldview and are increasingly twisted in knots and therefore filled with cognitive dissonance.
I personally don't like hunting down morons, but when they step on stage and refuse to yield, the should absolutely be mocked, shamed, and embarrassed, maybe even more so that they risk the health and safety of others with their idiocy. They didn't reason themselves into their positions, so I see no reason why we should try to reason them out.
