Breast Not Best? Study Suggests Rotavirus Vaccines Work Better With Formula.

Breastfeeding Rotavirus vaccines are heavily promoted in third world nations where lack of clean water and proper healthcare often leads to infection, diarrhea and even death. This abstract below from The Pediatric Infectious Disease Journal suggests that mothers should not breastfeed during the time of administration of rotavirus vaccines (RotaTeq and Rotarix) in order to increase their efficacy. How would women, who do not have access to clean water, make safe infant formula which, we believe, requires clean water? 

Background: Live oral rotavirus vaccines have been less immunogenic and efficacious among children in poor developing countries compared with middle income and industrialized countries for reasons that are not yet completely understood. We assessed whether the neutralizing activity of breast milk could lower the titer of vaccine virus and explain this difference in vitro.

Methods: Breast milk samples were collected from mothers who were breast-feeding infants 4 to 29 weeks of age (ie, vaccine eligible age) in India (N = 40), Vietnam (N = 77), South Korea (N = 34), and the United States (N = 51). We examined breast milk for rotavirus-specific IgA and neutralizing activity against 3 rotavirus vaccine strains-RV1, RV5 G1, and 116E using enzyme immunoassays. The inhibitory effect of breast milk on RV1 was further examined by a plaque reduction assay.

Findings: Breast milk from Indian women had the highest IgA and neutralizing titers against all 3 vaccine strains, while lower but comparable median IgA and neutralizing titers were detected in breast milk from Korean and Vietnamese women, and the lowest titers were seen in American women. Neutralizing activity was greatest against the 2 vaccine strains of human origin, RV1 and 116E. This neutralizing activity in one half of the breast milk specimens from Indian women could reduce the effective titer of RV1 by ~2 logs, of 116E by 1.5 logs, and RV5 G1 strain by ~1 log more than that of breast milk from American women.

Interpretation: The lower immunogenicity and efficacy of rotavirus vaccines in poor developing countries could be explained, in part, by higher titers of IgA and neutralizing activity in breast milk consumed by their infants at the time of immunization that could effectively reduce the potency of the vaccine. Strategies to overcome this negative effect, such as delaying breast-feeding at the time of immunization, should be evaluated.

Hi Sophie,
Just out of curiosity, how would one "evaluate" the "strategy" of "delaying breast-feeding at the time of immunization"? Is there another way to do this besides requesting the mother to refrain from breastfeeding?

sophie

Hi Donna,
Age of autism IS making the statement that there is a "suggestion" in this interpretation in the provided abstract that women "should not breastfeed".
This isn't true. There isn't such a suggestion at all.

What the interpretation says is that this strategy
"should be evaluated" That's it.

-other strategies that "should be evaluated" may include delaying the vaccine, or inventing a more potent one, etc.
These other strategies aren't being "suggested" in this abstract either.

Donna L.

Sophie,
The interpretation: "Strategies to overcome this negative effect, such as delaying breast-feeding at the time of immunization, should be evaluated" comes directly out of the abstract published in The Pediatric Infectious Disease Journal.

Age of Autism did not make this statement, the authors of the article in The Pediatric Infectious Disease Journal made this statement. Age of Autism, if you re-read the very first paragraph of this post, is asking how on earth could mothers without access to clean water possibly make safe formula for their infants?

Sophie


Um, here's what the interpretation actually says:

"Strategies to overcome this negative effect, such as delaying breast-feeding at the time of immunization, should be evaluated"

"SHOULD BE EVALUATED"

isn't the same as
"suggest that mothers SHOULD NOT BREASTFEED"
which is what you have said above.

Your 'analysis' is based on misinterpretation,
and is nothing more than typical misleading AoA hype 'n spin.

Incredible, the kind of spin they are putting on this one:
Interpretation: The lower immunogenicity and efficacy of rotavirus vaccines in poor developing countries could be explained, in part, by higher titers of IgA and neutralizing activity in breast milk consumed by their infants at the time of immunization that could effectively reduce the potency of the vaccine. Strategies to overcome this negative effect, such as delaying breast-feeding at the time of immunization, should be evaluated."

They've just proved that BREASTMILK DESTROYS THE VIRUS IN QUESTION. Basically, they've just proved that breastfed babies don't need vaccines in the first place.

They've just explained why breastfed babies are less likely to be severely autistic than formula-fed babies.

And they've just made a terrific case AGAINST vaccination.

www.fourteenstudies.org needs to add this to their website.

Read this sort of 'scientific' nonsense and know that evil is stalking the earth.

But of course!! Seriously! When the world wake up and smell all the rats only interested in making a quick buck at the expense of our health?!

Not only limited access to clean water, but also limited access to money to buy formula (aside from the week's worth of free samples). Then when you think about the other diseases against which breast milk is prophylactic (everything the mother has already had), you really doubt the wisdom of this recommendation (cutting out breast milk to increase the efficacy of one vaccine).

I recently had lunch with some friends from high school, one of whom now works in vaccines at Merck. We were talking about the lunacy of the chickenpox vaccine, and he said, "But when you have to grow to move your stock price, what else are you going to do?" What else, indeed? When you sell drugs, you can either hope more people will get sick and need your drugs, or you can sell drugs that nobody needs.

The Physicians Desk Reference (PDR) 1990, "it may be prudent to recommend abstention from breast-feeding for two to three hours before and after oral [polio] vaccination to permit the establishment of the vaccine viruses in the gut."*

Breast milk has enzymes which can neutralize the polio virus by as much as 80%. Doctors were telling mothers of the 40's and 50's not to breast feed even before the polio vaccine. The very part of the immune system which can protect young children from disease, "DOCTORS" were telling mothers "NOT TO DO".

Lets see, according to the medical community, for healthy children, inject them with mercury, and don't breast feed.

Yep, that pretty much sums it up.

Breasts are anti-vaccine!

It's the mother's fault!

sarah

so, kids in third world countries continue to show high rates of diarrhea with or without the magical rotavirus vaccine. Gee, maybe the vaccine doesn't target the actual problem?

idiot questions followed by the idiot advice to breastfeed less and vaccinate more. its amazing the new lows 'scientists' can hit when all conclusions are filtered through the religion of vaccines.

jen

Oh my God, I'm friggin speechless! Indeed how would they get clean water? Why is breast not best??!!

SarahS

I didn't breastfeed my son (hindsight is 20:20 of course) and I'm horrifed by this. What's interesting is the mention that Indian women have the highest IgA titers. I wonder if there is any link to this and turmeric consumption? Isn't that supposed to be anti-viral and has been shown to be effective in bowel cancer treatments and the like? Perhaps the active circumin ingredient is present in the breast milk and protects the infant's bowels too..

debbie voss

are you f'ing kidding me????

"Strategies to overcome this negative effect, such as delaying breast-feeding at the time of immunization, should be evaluated."

Negative for who? for Merck and Nestle...?

These people have the cheek of the devil.

Theresa O

Nestle has been part of this deadly game for years: "In order to sell more of its infant formula in third world countries, Nestle would hire women with no special training and dress them up as nurses to give out free samples of Nestle formula. The free samples lasted long enough for the mother's breast milk to dry up from lack of use. Then mothers would be forced to purchase the formula but, being poor, they would often mix the formula with unsanitary water or 'stretch' the amount of formula by diluting it with more water than recommended. The result was that babies starved all over the Third World while Nestle made huge profits from this predatory marketing strategy." (http://www.breastfeeding.com/advocacy/advocacy_boycott.html)

They must be psyched to have Merck as a marketing partner.

AnaB

So basically they are recommendingn moms not nurse around the time of the kids rotavirus vaccine. Do they not realize that when you quit nursing for a few days milk production depletes or goes away completely? So then we end up with babies in developing countries whose mothers who no longer can feed them because of a vaccine AND can neither afford formula administer it safely. Starving babies. Sheesh!

GrammaKnows

Wait a minute!

"Interpretation: The lower immunogenicity and efficacy of rotavirus vaccines in poor developing countries could be explained, in part, by higher titers of IgA and neutralizing activity in breast milk consumed by their infants at the time of immunization that could effectively reduce the potency of the vaccine."

Didn't that just say that breast milk protects against Rotavirus? Didn't that interpretation just say BECAUSE a child is breastfed they don't NEED a rotavirus vaccine???

In view of recent revelations, didn't that interpretation just say that breast fed babies in poor and developing countries would have the opportunity to NOT be exposed to wasting pig viruses because they are breastfed?

"Strategies to overcome this negative effect, such as delaying breast-feeding at the time of immunization, should be evaluated."

Didn't the rest of that paragraph say babies would be deprived of natural immunity in order to make them an equal victim of virally contaminated products as infants in developed countries(read US)?

Well, hell, boys & girls, that's sure one way to prevent the revelation that rotavirus vaccines are actually harming the kids in supposedly developed nations, now isn't it?
