Vaccines Are Made in China!

It shouldn’t be a secret that vaccines are made in China.

There are over 1.3 billion people in China, and no, they don’t import all of their vaccines from the United States.

Neither does India, for all of their 1.2 billion people.

For example, the Serum Institute of India Pvt. Ltd. makes many vaccines, including:

  • GeneVac-B – hepatitis B
  • Quadrovax – DTP-Hib combo
  • Pentavac – DTP-HepB-Hib combo
  • Tresivac – MMR
  • Poliovac – polio
  • Triple Antigen – DTP
  • MenAfriVac – meningococcal group A
At least 34 manufacturers make vaccines for use in China, like this Hib vaccine.

And there are over 34 vaccine manufacturers in China, including:

  • Chengdu Institute of Biological Products Co., Ltd
  • Hualan Biolgical Bacterin Co., Ltd
  • Jilin Brother Biotech Co., Ltd
  • Wuhan Institute of Biological Products
  • Lanzhouz Institute of Biological Products

These vaccine manufacturers in China, a mix of state run, private, and international joint ventures, help produce the vaccines used in China’s immunization program.

Some US vaccine companies even have vaccine manufacturing plants in China and other countries, but they make vaccines that are used in nearby parts of the world.

For example, Merck recently opened a new vaccine plant in Hangzhou, China to make vaccines to be used in the Asia Pacific region.

Should We Be Concerned About Vaccines Made in China?

If you are getting vaccinated in China, then you likely want to know more about where and how your vaccines are made. Everyone else should probably be wondering why anti-vaccine folks make such a fuss about this.

In addition to implying that vaccines are made under unsafe conditions, much of this anti-vaccine propaganda includes racist themes.

Parents who are concerned should understand that the United States doesn’t get any vaccines from China or India, or from Brazil, Cuba, Indonesia, or Russia for that matter.

The concern, of course, would be that it might be hard to test and verify these vaccines if they were.

“Following approval, FDA also carefully monitors the quality of vaccines—all manufactured lots must pass tests before they can be used. And as with all manufacturers of medical products, vaccine manufacturers must follow strict manufacturing standards. In addition, FDA conducts routine inspections of manufacturing sites.”

FDA on How does FDA assess the safety of vaccines?

Instead, vaccines that are used in the United States are made by:

  • Emergent Biosolutions – USA – Anthrax vaccine
  • ID Biomedical Corp – Canada – Fluvaval
  • GSK Vaccines – based in Belgium, but vaccines are made in Belgium (Boostrix, Cervarix, Energix-B, Havrix, Hiberix, Infanrix, MenHibrix, Kinrix, Pediarix, Rotarix), Germany (Boostrix, Fluarix, Infanrix, Kinrix, Pediarix, Rabavert), and Italy (Bexsero, Menveo)
  • MedImmune – USA – FluMist
  • Merck – USA – BCG, Gardasil9, MMRII, PedvaxHIB, PneumoVax23, ProQuad, RecombivaxHB, RotaTeq, Vaqta, Varivax, Zostavax are made at Merck’s vaccine manufacturing plants in West Point, Pennsylvania, Elkton, Virginia, and Durham, North Carolina
  • PaxVax – USA – their Vivotif typhoid vaccine is made in Thörishaus, Switzerland
  • Pfizer – USA – (Prevnar, Trumenba)
  • Protein Sciences Corporation – USA – Flublok
  • Sanofi Pasteur – Canada (Adacel, Daptacel, Pentacel), France (IPOL, Pentacel), USA (Menactra, YF-Vax, ),
  • Seqirus – USA – Afluria, Flucelvax, Fluvirin
  • Valneva (Intercell USA) -their  Japanese encephalitis vaccine (IXIARO) is made in Livingston, Scotland, UK
  • Valneva Sweden AB – their Dukoral cholera vaccine is made in Solna, Sweden

A little competition in the vaccine industry wouldn’t be a horrible thing though.

Vaccines are expensive

They are safe, but expensive. Necessary too.

What to Know About Vaccines Made in China

Although plenty of vaccines are made in China, the vaccines that are used in the United States are not, although anti-vaccine folks use this as a talking point to scare parents away from vaccinating and protecting their kids.

For More Information on Vaccine Manufacturer Sites:

Are Vaccines Evaluated for Mutagenicity, Carcinogenicity or Impairment of Fertility?

Spend much time on anti-vaccine websites or forums and you will soon be warned that vaccines are not evaluated for mutagenicity, carcinogenicity or impairment of fertility.

Actually, you can often read that simply by reading a vaccine’s package insert.

Mutagenicity, Carcinogenicity and Impairment of Fertility

What are these term exactly?

  • mutagenicity – being known or suspected of causing mutations in our DNA, which can lead to cancer
  • carcinogenicity – being known or suspected of being able to cause cancer
  • impairment of fertility

And why are they listed in Section 13 of a vaccine’s package insert?

The Section 13 Vaccine Conspiracy?

More importantly, why do some folks talk about Section 13.1 of a vaccine’s package insert like it is Area 51 or Agenda 21?

“13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, mutagenesis, impairment of fertility. This subsection must state whether long term studies in animals have been performed to evaluate carcinogenic potential and, if so, the species and results. If results from reproduction studies or other data in animals raise concern about mutagenesis or impairment of fertility in either males or females, this must be described. Any precautionary statement on these topics must include practical, relevant advice to the prescriber on the significance of these animal findings. Human data suggesting that the drug may be carcinogenic or mutagenic, or suggesting that it impairs fertility, as described in the “Warnings and Precautions” section, must not be included in this subsection of the labeling.”

CFR – Code of Federal Regulations Title 21

So no material for a vaccine conspiracy?

Just information on studies in animals?

“The goals of the nonclinical safety evaluation generally include a characterization of toxic effects with respect to target organs, dose dependence, relationship to exposure, and, when appropriate, potential reversibility. This information is used to estimate an initial safe starting dose and dose range for the human trials and to identify parameters for clinical monitoring for potential adverse effects. The nonclinical safety studies, although usually limited at the beginning of clinical development, should be adequate to characterize potential adverse effects that might occur under the conditions of the clinical trial to be supported.”

FDA on Guidance for Industry M3(R2) Nonclinical Safety Studies for the Conduct of Human Clinical Trials and Marketing Authorization for Pharmaceuticals 

It still sounds important though…

Are Vaccines Evaluated for Mutagenicity, Carcinogenicity or Impairment of Fertility?

As important as vaccines are, no one wants them to mutate our children, cause cancer, or keep them from having babies.

Fortunately, they don’t!

“To ensure the safety of new vaccines, preclinical toxicology studies are conducted prior to the initiation of, and concurrently with, clinical studies. There are five different types of preclinical toxicology study in the evaluation of vaccine safety: single and/or repeat dose, reproductive and developmental, mutagenicity, carcinogenicity, and safety pharmacology. If any adverse effects are observed in the course of these studies, they should be fully evaluated and a final safety decision made accordingly. ”

M.D. Green on the Preclinical Toxicology of Vaccines

And that’s because vaccines are safe and well tested.

Then why do anti-vaccine folks scare parents into thinking that vaccines are missing necessary testing when the package insert states that they are “not evaluated for mutagenicity, carcinogenicity or impairment of fertility?”

Cancer is caused by a host of factors. Vaccines have a role in preventing and potentially treating some types of cancer. Components of vaccines and their associated cell lines that viruses are grown in are safe and have not been shown to induce cancer in the vaccinated host.
“Cancer is caused by a host of factors. Vaccines have a role in preventing and potentially treating some types of cancer. Components of vaccines and their associated cell lines that viruses are grown in are safe and have not been shown to induce cancer in the vaccinated host.”

Probably because it sounds scarier than saying that vaccines have a low risk of inducing tumors and that there are very specific guidelines and rules for when a manufacturer needs to perform fertility studies.

That means that if  a package insert says that it has “not been evaluated,” it is simply because it was not necessary or appropriate. It is not because they just didn’t want to do it and left those tests out.

That doesn’t sound as scary though.

All necessary pre-clinical or nonclinical testing is done on vaccines and their components. You just don’t see long term testing that would be listed in the package insert unless the initial tests found a problem.

Also remember that vaccines are monitored through several passive and active safety systems that would detect issues with mutagenicity, carcinogenicity, and impairment of fertility.

And several vaccines actually prevent cancer!

What to Know About Vaccines and Mutagenicity, Carcinogenicity and Impairment of Fertility

Vaccines are appropriately evaluated for mutagenicity, carcinogenicity and impairment of fertility, when necessary, as a part of pre-clinical or nonclinical studies that occur even before the first phase one studies on people.

Vaccine Testing and Development Timeline and Myths

New vaccines must go through a long journey before they are finally approved by the FDA and get added to the recommended immunization schedule.

Vaccine Testing and Development Myths

There are many myths and much misinformation surrounding vaccine testing and development that is used to scare parents away from vaccinating their kids.

Have you heard that vaccines aren’t tested together?

Or that flu vaccines or Tdap were never tested on pregnant women?

Then there are the myths about fast-tracking, and that important steps are skipped when a vaccine is on fast track for FDA approval, or that the whole vaccine testing and development process happens very quickly.

Vaccine Testing and Development Timeline

The vaccine development process is anything but quick.

“Vaccine development is a long, complex process, often lasting 10-15 years and involving a combination of public and private involvement.”

The History of Vaccines on Vaccine Development, Testing, and Regulation

During this time of the exploratory and pre-clinical stage research and then phase 1,2, and 3 trails, vaccines are:

  • tested on animals
  • tested on small groups of people
  • tested on larger groups of people
  • tested alone
  • tested together with other vaccines
  • tested for safety
  • tested for efficacy (to make sure they work)

This often includes double-blind, placebo controlled vaccine trials.

Fast tracking does speed the process up, but not because any of the testing is skipped. The researchers just get more frequent meetings and communication with the FDA and “Eligibility for Accelerated Approval and Priority Review, if relevant criteria are met.”

“Vaccine development is a complex multidisciplinary activity, combining understanding of host-pathogen interactions at the molecular level, with clinical science, population-level epidemiology and the biomechanical requirements of production.”

Anthony L. Cunningham, et al on Vaccine development: From concept to early clinical testing

Testing doesn’t stop once a vaccine is approved by the FDA and is added to the immunization schedule either. We often continue to see testing for vaccine safety and efficacy using phase 4 trials and with our post-licensure vaccine safety system, including VAERS and the Vaccine Safety Datalink.

And of course testing continues long after we begin using vaccines to see how long their protection will last. For example, because of continued testing, we now know that Gardasil and Cervarix are providing protection that lasts at least 8 and 9 years.

What To Know About Vaccine Testing and Development

From pre-clinical studies and years of phase 1, 2, and 3 trials to continued monitoring after a vaccine is approved and added to the immunization schedule, the vaccine testing and development process helps make sure that vaccines are safe and that they work.

Are Vaccines Tested Together?

If you are on the Fence about vaccines, one issue that might have you scared is that the idea that vaccines aren’t tested together.

So maybe they tested the Prevnar vaccine, but did they test it with the Hib vaccine?

And did they test the Prevnar and Hib vaccine with the Pediarix vaccine?

After all, kids get all of those vaccines at their two, four, and six month well child checkups.

Vaccines Are Tested Together

It is not hard to find evidence that most combinations of vaccines are in fact tested together.

For example (and this is not a complete list):

  • Rotarix was tested with Pediarix (DTaP-HepB-IPV), Prevnar, and Hib
  • Prevnar 13 was tested with DTaP, IPV, hepatitis B and Hib
  • Prevnar 13 was tested with MMR, Varicella, and hepatitis A
  • MenC with DTaP-IPV-HepB-Hib
  • MenC with MMR
  • MMR and Varicella with Hib, Hepatitis B, and DTaP
  • hepatitis A and hepatitis B with either MMR or DTaP-IPV-Hib
  • HPV vaccine for babies
  • Flumist with MMR and Varicella
  • Kinrix (DTaP-IPV) with MMR and Varicella
  • HPV9 with Tdap and Meningococcal vaccines
  • Tdap with influenza vaccine
  • Meningococcal vaccine with influenza vaccine

And even after a vaccine is added to the immunization schedule and it is given together with other vaccines, our post-licensure vaccine safety monitoring systems, from VAERS to the Vaccine Safety Datalink, kick in to make sure that they are indeed safe and effective.

The Myth That Vaccines Aren’t Tested Together

If it is clear that vaccines are in fact tested together, then why do some folks still believe that they aren’t?

Bob Sears appeared on Fox & Friends in 2010 for the segment
Bob Sears appeared on Fox & Friends in 2010 for the segment Vaccines: A Bad Combination?

Hopefully everyone sees the irony in Dr. Bob saying something about vaccines being untested, as he is infamous for pushing his own made up and completely untested alternative vaccine schedule.

“Babies get as many as 6 or 7 vaccines altogether…and the CDC is admitting that they don’t always research them that way.”

Dr. Bob Sears on Fox & Friends Vaccines: A Bad Combination?

When did they admit that???

“We’ve researched the flu vaccine in great detail and it seems safe when it’s given alone, but the CDC has never researched the flu vaccine when you give it in conjunction with all the other infant shots…and that’s what we’re worried about. ”

Dr. Bob Sears on Fox & Friends Vaccines: A Bad Combination?

So, what about the flu vaccine?

A 2013 report from the Institute of Medicine found that there was no evidence that vaccines caused ADHD.
A 2013 report from the Institute of Medicine stated that “Each new vaccine considered for inclusion in the immunization schedule is tested within the context of the existing schedule and reviewed by clinical researchers, who analyze the balance of demonstrated benefits and risks.”

While most kids get their flu vaccine by itself, just before the beginning of flu season, some might get it when they see their pediatrician for a regular checkup, at the same time they are due for other vaccines.

Not surprisingly, Dr. Bob was wrong, and several studies have shown that the flu vaccine can be safely given with other vaccines.

And don’t forget, any problems with co-administration of vaccines would show up in post-licensure vaccine safety testing.

That’s how a very small increased risk of febrile seizures was found during the 2010-11 flu season in toddlers who received either DTaP or Prevnar and a flu shot at the same time.

The very small extra risk doesn’t mean that you still can’t get the vaccines at the same time if your child needs them all though. Remember that febrile seizures “are temporary and do not cause any lasting damage.”

It will be even more reassuring to some parents that another study “examined risk of febrile seizures (FS) after trivalent inactivated influenza vaccine (TIV) and 13-valent pneumococcal conjugate vaccine (PCV13) during the 2010-2011 influenza season, adjusted for concomitant diphtheria tetanus acellular pertussis-containing vaccines (DTaP)” and found no extra risk for febrile seizures.

“Vaccines can generally be co-administered (i.e. more than one vaccine given at different sites during the same visit). Recommendations that explicitly endorse co-administration are indicated in the table, however, lack of an explicit co-administration recommendation does not imply that the vaccine cannot be co-administered; further, there are no recommendations against co-administration.”

Summary of WHO Position Papers – Recommendations for Routine Immunization

Also remember that “there are no recommendations against co-administration of vaccines,” unless of course, you are getting your advice from Bob Sears…

 

What To Know About Vaccines Being Tested Together

Vaccines are thoroughly tested for both safety and efficacy and they are also tested in many of the different combinations on the routine childhood immunization schedule.

Where are the Double Blind Placebo Controlled Randomized Trials about Vaccines

Have you ever heard that there are no double-blind, placebo-controlled randomized clinical trials for vaccines?

It isn’t true.

There are many double-blind, placebo-controlled randomized clinical trials that involved:

  • flu shots
  • pneumonia shots
  • HPV vaccines
  • potential HIV vaccines
  • malaria vaccines
  • rotavirus vaccines
  • Dengue vaccine
  • Staphylococcus aureus vaccine

That’s good, because double-blind, placebo-controlled randomized clinical trials are considered the “gold standard” when you do medical research.

“Placebo Control – A comparator in a vaccine trial that does not include the antigen under study. In studies of monovalent vaccines this may be an inert placebo (e.g. saline solution or the vehicle of the vaccine), or an antigenically different vaccine. In combined vaccines, this may be a control arm in which the component of the vaccine being studied is lacking.”

WHO on the Guidelines on clinical evaluation of vaccines: regulatory expectations

Tragically, many more folks got pneumonia and died if they got the saline placebo instead of the vaccine in this study.
Tragically, many more folks got pneumonia and died if they got the saline placebo instead of the vaccine in this study.

But do they all use a saline placebo?

No, not always, which typically leads anti-vaccine types to dismiss them outright and push anti-vaccine misinformation, including that they are never done.

It seems that they aren’t worried so much about the antigens in vaccines anymore (the Too Many, Too Soon argument), but are now more concerned about other vaccine ingredients. They will only be satisfied with a saline placebo, but they must miss the part about wanting the trial to be double-blinded, which gets harder to do if the placebo doesn’t look and “feel” like the vaccine.

And they miss the part that “not always” doesn’t mean never.

Gardasil is a good, recent example of a vaccine that had a double-blind, placebo-controlled (using a saline solution without an adjuvant) trial for safety.

Others vaccine trials use a saline control too, including efficacy and safety trials for a new recombinant, live, attenuated, tetravalent dengue vaccine (it worked and had a good safety profile), a malaria vaccine (a phase I dose escalation study), a universal flu vaccine, a Staphylococcus aureus vaccine, etc.

The Ethics of Placebo Use in Vaccine Trials

So why haven’t placebo control studies been done even more routinely then?

Why isn’t every vaccine on the immunization schedule or every combination of vaccines tested using a double-blind, placebo controlled study?

“Placebo use in vaccine trials is clearly acceptable when (a) no efficacious and safe vaccine exists and (b) the vaccine under consideration is intended to benefit the population in which the vaccine is to be tested.”

Placebo use in vaccine trials: Recommendations of a WHO expert panel

Of course, the answer is that in order to do this type of study, you would have to have a very good justification for leaving many of the kids unprotected and at risk for a vaccine-preventable disease.

Instead, as is discussed in the article “Current topics in research ethics in vaccine studies,” if a vaccine is “already in use in some other country or community which is more or less comparable to site where the trial is planned, that vaccine should be used as the comparator.”

So instead of a placebo, it is more common “to give another vaccine that provides comparable benefit against another disease, or more willingly, against similar disease caused by different agents.”

When can you use a placebo control?

The article states that “placebo controls are ethically acceptable when there is no proven vaccine for the indication for which the candidate vaccine is to be tested.”

But get educated and don’t be fooled, many double-blind, placebo-controlled randomized clinical trials have been done with vaccines.

What to Know About Placebo Use in Vaccine Trials

When it is ethical to do so, placebos have been used in vaccine trials, even saline placebos.

Vaccines are safe, effective, and necessary.

They aren’t full of toxins.

They have been tested together.

Pediatricians do know a lot about vaccines. What they may not know is how to counter every anti-vaccine argument that you might have heard of, read about, or with which one of your family members is scaring you.

“Pediatricians who routinely recommend limiting the numbers of vaccines administered at a single visit such that vaccines are administered late are providing care that deviates from the standard evidence-based schedule recommended by these bodies.”

American Academy of Pediatrics

You can rest assured that these arguments have all been debunked, often many years ago, but they keep coming up, over and over again. In fact, today’s anti-vaccine movement uses many of the same themes as folks used when the first vaccines were introduced over one hundred years ago.
