unfortunately no one knows the answer to your question - because there is no credible research on what happens when humans take an industrial bleaching agent orally - for obvious ethical reasons such trails have not been done.
as wladek posted - we know bleaching agents in sufficient concentrations kill 99.9% of all known germs when tested in a petri dish - including those in biofilms,
but i do not think any actual research has been done on what concentrations of chlorine dioxide appear in the blood and tissues after ingesting it in the concentrations the MMS people suggest. it could well be that in low concentrations it is mostly neutralised inside the digestive tract and does not reach effective concentrations in the blood and tissues - and in high concentrations damages the intestines and vascular system - and in fact all living tissues - due to its oxidising action - and not just microorganisms.
i read the the USA extradited and prosecuted the owners of the MMS scheme from Columbia where they had fled to avoid prosecution in connection with 7 deaths related to MMS and official figures for poisonings due to chlorine dioxide in the USA alone were 16,000 cases between 2014 and 2019.
presumably these 7 people who died also believed MMS was safe, preferring to believe a few individuals who were making $100k a month from the scam over all other sources.

By then there was evidence that using MMS could be fatal. In 2009, American retiree Doug Nash and his Mexican wife, Sylvia Fink, embarked on a circumnavigation of the globe aboard their sailboat, Windcastle. On their way to the Solomon Islands, they met a couple, a Belgian man and an American woman, who sold MMS to Fink as a prophylaxis against malaria. On an August morning, after a night of dancing with villagers on the remote island of Epi to celebrate an annual canoe race, Fink added 2 drops of MMS to 10 drops of lime juice and drank the mixture on the boat’s sundeck. Within 15 minutes, she’d started vomiting uncontrollably, continuing until she was throwing up only bile. She also suffered burning urinary pain. Nash radioed for medical assistance, but by sundown Fink had lapsed into a coma. By 9 p.m. she was dead.
The autopsy report noted a significantly high level of methemoglobin in the blood—a symptom of high exposure to chlorite—which would have effectively starved her body of oxygen. “It was a substance, used in the fashion that was being recommended, that was definitely acting like a poison would on your gut,” Nash says of the MMS. “Her body got so dehydrated that her organs started to fail.

According to court records, Smith had emailed his father outlining the economics of selling MMS and associated products, noting that “100,000 bottles at $15 and 100,000 books at $15 is $3 MILLION dollars. Double that and we’re the SIX MILLION DOLLAR MEN.”

please be careful with what you put in your body - there are many people out there who would take advantage of sick and dying people - and there are much safer and better substantiated treatments available for lyme disease and associated conditions.
all the best
