the study the article
is discussing didn’t test anyone who wasn’t vaccinated.

their finding were that you can have a false positive after an MMR vaccine and other respiratory illnesses may go untreated.


So? The study showed shedding. The question is if shedding could have contributed to the outbreak. You know, scientific questioning.

Conclusion: Shedding of measles vaccine RNA is not uncommon and vaccine RNA can be detected up to 29 days post MMR; the amount of vaccine RNA shedding is low indicated by high Ct values. Clinicians and public health officials should consider performing measles vaccine testing on those testing positive for measles within one month of MMR vaccination, especially if the Ct value is high and definitive epidemiological links are absent.

it’s important to be aware of shedding the live virus after the vax., especially if you have a very young child in the same home. There’s a reason you’re told not to allow a child who recently had the measles vax around young babies.


No pediatrician worth their salt would tell you that. Shed virus from MMR doesn't cause illness, even in the immunocompromised. The oral polio vaccine would rarely cause polio infection via shed virus, but we haven't used that in the US in 25 years. MMR shedding never infects anyone.

Yes. And measles is an RNA virus. Thus, the vaccine is sometimes called an RNA vaccine. You can literally google the exact words.


Measles is an RNA virus, but MMR is not an RNA vaccine, it's a LAV (live attenuated vaccine). LAV's can be used for RNA viruses or DNA viruses. Here's a brief wikipedia article on RNA vaccines. It doesn't mention MMR, because MMR is not an RNA vaccine.

because the article posted in the op is claiming that this is “ Proof That Vaccinated Individuals Can Spread Measles”

Again, this study didn’t look into that at all.

true or false, this isn’t evidence of it one way or other.

Basic scientific literacy

Interesting. Our pediatrician who was head of the Texas State Board of Pediatrics spoke about measles rna being detected in the air and surfaces up to 3 weeks. She also specializes in international pediatric medicine.

Are you autistic? If a vaccine addresses an RNA virus, it can’t be called an RNA vaccine?

You should take your argument up with the author of the article, not the OP.

Again, the OP did not confuse rna with mRNA. He simply quoted an article.

Simple enough. Post a link to a scientific or medical journal that uses the term "RNA vaccine" to describe the MMR vaccine. LAV's are not RNA vaccines. They are live attenuated virus vaccines (which can be used against DNA or RNA based viruses).

Measles is the most infectious disease there is. That's true. But there is a difference between wild-type strains and vaccine attenuated strains. the strains in vaccines don't cause measles infections. Wild-type measles is bad news. It kills about 1 in a thousand unvaccinated people and so there are probably more cases out there in West Texas than they've identified.

How about you just argue with the author of the article now?

no one calls them that though.

I googled “rna vaccine” and every response was about mRNA vaccines.

If you google “what kind of vaccine is MMR” you get “attenuated live virus vaccine”

You can call it anything you like. You can call it an aminoglycoside antibiotic if you prefer. Your nomenclature wouldn't be accepted in the scientific or medical community. They don't call MMR vaccine an "RNA vaccine" because it confuses the MMR LAV with a different type of vaccine.

I get that. I’m simply saying that the article called it that bc it was discussing a vaccine that targeted and RNA virus and the shedding of RNA after vaccine. It’s not inaccurate even if it’s not how it’s usually referred to by that name.

Ok. That wasn’t the point of the author referring to it that way. He wasn’t publishing in a medical journal.

This is SFP level of semantics obsession

OP, change the title to this so they will shut up:

It has to be autism. I don’t know why I even tried to explain for so long

I mean, direct quote from the article:
quote:

The question now is: If the vaccine strain virus is being shed, could it be capable of infecting others?

This study does not answer that question, but it does confirm that measles vaccine RNA persists in the body long after injection.

The one thing i’ve learned since covid is people cannot and do not read scientific studies.

they read headlines.

and 50% of the time the headline will directly conflict with a disclaimer like that in the study.

and i’ll even say this: if you can get infected from
someone who got a LAV vaccine, does that cause pathology or did they basically vaccinate you. Is the virus your getting attenuated too?

and what’s lost is the main take away from the study was: if you’re getting a positive test measles but overall the epidemiology doesn’t matched, see if they’ve been vaccinated in the last 30 days.

Clearly.


The article addresses the exact things you brought up, yet you ignored them or didn't read them
