It’s Just More Anti-Vaccine Misinformation

Vocal vaccine deniers don’t like to get called out for pushing anti-vaccine misinformation.

They like to think they are giving folks ‘more information.’

More anti-vaccine misinformation from the usual suspects.
Nope. It’s just more misinformation about vaccines to scare parents away from vaccinating and protecting their kids.

In reality, it’s just more misinformation about vaccines…

It’s Just More Anti-Vaccine Misinformation

It’s not even just Bob doing it anymore.

Larry Cook stuffed all of the basic components of anti-vaccine propaganda into one little comment.

That’s a lot of misinformation stuffed into one comment…

Got something else?

Yup. Measles. A lot of measles.

A week-long rash that is accompanied by a high fever, cough, and irritability. A week-long rash that can sometimes lead to encephalitis and even death.

A week-long rash that is easily prevented with two doses of the MMR vaccine, which doesn’t shed, rarely causes vaccine-associated measles (38%???), and rarely causes serious side effects.

A life-threatening disease that your kids might unnecessarily be at risk to get because you are listening to these folks who don’t think that vaccines are ever necessary or ever work.

Larry Cook thinks that he knows the real truth about vaccines.

Is that what you believe?

Del Spreads Misinformation

And there are still others spreading misinformation.

“I know that a lot of people read, ‘Oh, Del spreads misinformation,’” he said. “That’s an opinion. I like to call it missed information. This is the information that the mainstream media establishment doesn’t want you to hear.”

I attended an Orthodox anti-vaccine rally. Here’s what I saw.

So what’s some of the “missed information” that Del Bigtree is spreading?

“Over the course of about 12 minutes, Bigtree linked vaccines to the Holocaust and then to child sacrifice. He compared them to Nazi experimentation on unwilling Jewish medical subjects, then to the intentional ritual murder of children, in an effort to debunk the scientific consensus that a critical mass of vaccinated people, or herd immunity, means that even those who cannot be vaccinated for genuine medical reasons will have some protection from getting sick.”

I attended an Orthodox anti-vaccine rally. Here’s what I saw.

While it isn’t surprising that someone like Del Bigtree would say these things, that he would do it at an anti-vaccine rally in the middle of the biggest measles outbreak in 27 years in New York is unbelievable.

More Misinformation from Bob Sears

Want to hear the latest misinformation from Bob Sears?

Where in the package insert does it say that there are very small pieces of fetal tissue in the hepatitis A or chickenpox vaccines???
Where in the package insert does it say that there are very small pieces of fetal tissue in the hepatitis A or chickenpox vaccines???

The guy who brought us his own made up vaccine schedule is claiming that there are “physical pieces of fetal tissue” in vaccines.

Bob Sears usually bans people who correct his misinformation. Let's see how long this comment lasts on his Facebook page...

There aren’t.

Yes, some vaccines are made with fetal embryo fibroblast cells from cell lines that were derived (they can replicate infinitely) from two electively terminated pregnancies in the 1960s.

That certainly does not mean that any vaccines contain aborted fetal tissue though.

The cells used today have been copied, over and over again. They are descendant cells, which is why a common way to explain all of this is to say that vaccines are said to have a “distant association with abortion.”

Missed Information About Vaccines

Not only do vaccines not contain aborted fetal tissue, the fetal embryo fibroblast cells that are used to grow the viruses in these vaccines are mostly removed from the final vaccine our kids get!

“Some vaccines may contain residual quantities of components used during the manufacturing process, including inactivating agents, antibiotics, and cellular residuals. These agents are removed at the end of the manufacturing process, but trace amounts may be present in some vaccines.”

NIH on Other Vaccine Ingredients

If any of the fetal embryo fibroblast cells are present, it is only in trace amounts and as cellular residuals, not even as complete cells.

When used, WI-38 and MRC-5 cells are not necessarily listed in the excipient summary if they are not contained in the final vaccine, but they are still listed in the vaccine's package insert.

Anti-vaccine folks don’t usually tell you that…

What ever they now want to call the anti-vaccine misinformation they are pushing to folks, just understand that it is all the same propaganda that is designed to scare you away from vaccinating and protecting your kids.

Fetal Bovine Serum in Vaccines

Are you worried that there might be fetal bovine serum in your child’s vaccines?

Fetal Bovine Serum in Vaccines

Are you wondering why they even put fetal bovine serum in vaccines?

Well, it is not really added to the vaccine, like a preservative or other vaccine ingredient.

Instead, the FDA explains why fetal bovine serum might be in some vaccines:

“In the manufacture of viral vaccines, the virus may be grown in cells.  These cells need a source of nutrition, which in some instances may be provided by fetal bovine serum.”

Common Ingredients in U.S. Licensed Vaccines

So fetal bovine serum is used as a growth media to provide nutrients to viruses.

What about bovine serum albumin?

Bovine serum albumin actually comes from fetal bovine serum. It is one of the major components and is very similar to human serum albumin.

“Bovine serum albumin (BSA) is a major component of fetal bovine serum (FBS), which is commonly used as a culture medium during vaccine production. Because BSA can cause allergic reactions in humans the World Health Organization (WHO) has set a guidance of 50 ng or less residual BSA per vaccine dose.”

Loughney et al on Residual bovine serum albumin (BSA) quantitation in vaccines using automated Capillary Western technology.

And they are eventually removed from vaccines through multiple processing and purification steps. Any that remains is only in residual trace amounts.

So even though you don’t have to be concerned about it, there likely isn’t even any fetal bovine serum or albumin left in any of the shots that your kids get!

That’s also why fetal bovine albumin is unlikely to cause or trigger vaccine allergies.

There is also no risk that using these materials from cows could cause mad-cow disease.

Chick Embryos and Vaccines

There are no chick embryos in vaccines.

Chick Embryos and Vaccines

Some vaccines, like MMR, are made or are grown in chick embryo fibroblast cells.

Others, like many influenza vaccines and the yellow fever vaccine, are actually grown in the allantoic sacs of chick embryos.

But just like vaccines that are grown in baker’s yeast, most of the egg proteins are removed as the vaccine antigens are removed and purified.

Yeast in Vaccines

Yeast in vaccines?

Yeast in Vaccines

Yes, a few vaccines may contain trace amounts of yeast proteins.

Why?

Those vaccines are actually made in baker’s yeast (the growth medium), kind of like other vaccines are grown in cell cultures, etc.

And although most of the yeast proteins are removed as the vaccine antigens are removed and purified, some residual yeast proteins might remain in the vaccine.
