Are There Generic Vaccines?

We are used to drugs becoming generic once they have been around for a while, which may have you wondering if we have generic vaccines too.

“Who owns the patent on this vaccine?
Well, the people, I would say. There is no patent. Could you patent the sun?”

Jonas Salk

In addition to vaccines that don’t have patents, others have lost their patent protection, which typically lasts for only 20 years, so it seems like we could have generic vaccines.

Are There Generic Vaccines?

And we have.

Consider that once upon a time:

  • the Texas Department of Health Resources made up to 7 different vaccines
  • the University of Illinois made a BCG vaccine
  • the Michigan Department of Public Health made up to 8 different vaccines
  • Massachusetts Public Health Biological Laboratories (Mass Biologics) made several vaccines

These included many generic vaccines, including DPT and IPV.

In addition to Tenivac, made by Sanofi Pasteur, MassBiologics makes a generic Td vaccine.

In fact, the Massachusetts Public Health Biological Laboratories continues to make the last remaining generic vaccines, DT and Td.

Why Aren’t There More Generic Vaccines?

Couldn’t more pharmaceutical companies make vaccines, including more generic vaccines, so that they could be less expensive?

“In sum, although patent protection remains the major barrier to the production of affordable small-molecule generics, access to trade-secret–protected information and know-how present major additional obstacles to generic production of vaccines.”

Unfortunately, unlike drugs, patents aren’t the only issue when making a generic vaccine. You also need the expertise, investment, and studies to prove that your generic vaccine is as safe and effective as similar vaccines.

Too Many Too Soon Revisited

You know how anti-vaccine folks like to say that kids get too many vaccines at too early an age these days?

Four generations of vaccines or vaccine misinformation?
Four generations of vaccines or vaccine misinformation?

It’s not like the ‘good old days,’ when instead of more vaccines, they just got more diseases.

But looking at the immunization schedules from the 1950s and 1960s, you should know that folks back then got a lot more vaccine doses than you have been led to believe.

Too Many Too Soon Revisited

And you know what else? Those vaccines include the “crude brew” of DPT and smallpox, which contained far more antigens per vaccine than today’s vaccines.

The 1951 immunization schedule published by the AAP.
The 1951 immunization schedule published by the AAP.

By six months, these kids got the smallpox vaccine (200 antigens) and three doses of DPT (3,002 antigens), for a total of 9,206 antigens.

And today?

They could get up to about 174 antigens, including

  • DTaP: 7 antigens * 3 doses = 21 antigens
  • IPV: 15 antigens * 3 doses = 45 antigens
  • Hib: 2 antigens * 3 doses = 6 antigens
  • Prevnar13: 14 antigens * 3 doses = 42 antigens
  • hepatitis B: 1 antigen * 3 doses = 3 antigens
  • rotavirus: 15 antigens * 3 doses = 45 antigens
  • Flu: 12 antigens * 1 dose = 12 antigens

That’s 9,032 fewer antigens or less than 2% of what they once got, even though they are protected against many more diseases!

Not worried about antigens anymore?

Just remember that in the 1950s, in addition to all of these extra antigens, except for smallpox, these vaccines were made with thimerosal and aluminum.

Not that those ingredients were dangerous then, or today. It’s just more recently that folks decided that they were scary.

But it is just important to keep in mind that it is misleading to say that kids only got 2 vaccines then, and now get 69, 72, or 74.

In fact, it’s not just misleading, it’s lying.

If you use the same anti-vaccine math, in the 1950s, they actually got at least 22 doses by age 9 or 10! And they got even more once the polio vaccine was introduced in 1955.

Vaccines don't destroy your life force...
Vaccines don’t destroy your life-force…

Anti-vaccine folks still try to downplay the number of doses of vaccines folks got back in the 1950s and 1960s though.

Why?

To scare you.

Kids do get more vaccines, but they have far fewer antigens, and more vaccines means more protection against more diseases.

In the 1950s, 60s, and 70s, kids were dying of diseases that are now vaccine preventable, including rotavirus, hepatitis A and B, chicken pox, pneumococcal meningitis, epiglottitis, Hib meningitis, and meningococcal meningitis, etc.

What about the idea that all of the extra vaccine doses were added right after the passage of the National Childhood Vaccine Injury Act of 1986?

Believe it or not, it was almost nine years, 1995, before a new vaccine (Varivax) was added to the immunization schedule. Others were slowly added after that, including:

  • hepatitis A (1996)
  • rotavirus (1998)
  • Prevnar (2000)
  • Menactra (2006)
  • Tdap (2006)
  • Gardasil (2006)

The biggest change? The one that helps boost the numbers of doses so that anti-vaccine folks can try and say that kids get 72 doses of vaccines?

That was when we started recommending flu shots for healthy kids, beginning with infants for the 2004-05 flu season. Remember, nearly a third of their list is just flu shots…

What about Hib and Hep B? They were both added right before the passage of the National Childhood Vaccine Injury Act of 1986.

Guess what?

Nothing about their little anti-vaccine memes are true.

Vaccines are safe, with few risks, and are necessary.

Making a Better Pertussis Vaccine

So we know that we need a better pertussis vaccine.

DTaP and Tdap just aren’t doing the job that they should be doing.

Whooping Cough is back, again.
Whooping Cough is back, again.

So when will we get one?

Making a Better Pertussis Vaccine

Since anti-vaccine folks are always talking about the 300 new vaccines in the pipeline, you would think that we would have had several new pertussis vaccines by now…

Unfortunately, we don’t.

What we do have is some good candidates, including:

  • new acellular pertussis vaccines, either with more antigens or an adjuvant
  • a new live attenuated nasal vaccine, BPZE1
  • new whole-cell vaccines with reduced endotoxin contents (so should have fewer side effects that then original whole-cell pertussis vaccine – DTP)

Before you get too excited, keep in mind that none of these vaccines will be available in your pediatrician’s office any time soon. Developing a new vaccine takes a lot of time.

BPZE1 has started phase 2a trials though.

What do we do until we get new pertussis vaccines?

“We should be more vigilant than we have been in the past to recognize and treat pertussis in all age groups so that transmission to young infants is reduced. Most important (although not discussed in this review) is to ensure that all pregnant women receive the Tdap vaccine between 27 and 36 weeks’ gestation with each pregnancy. Also, we should consider routinely administering Tdap vaccine every 3 years to all adolescents and adults who were primed with a DTaP vaccine.”

James D. Cherry on The 112-Year Odyssey of Pertussis and Pertussis Vaccines—Mistakes Made and Implications for the Future

We should keep using the pertussis vaccines we have!

Vaccines work, even when they aren’t as effective as we would like.

Choose to Stop Spreading Anti-Vaccine Propaganda

You have a choice.

Right now.

You can continue to share and spread anti-vaccine propaganda, helping scare other folks away from vaccinating and protecting their kids, or you can stop.

Choose to Stop Spreading Anti-Vaccine Propaganda

Why is the above meme anti-vaccine propaganda?

For one thing, there aren’t 200 vaccines in the pipeline!

There are actually very few new vaccines being developed that have any chance of making it onto the immunization schedule anytime soon. Many of the so-called vaccines in the pipeline are either not for infectious diseases (many are therapeutic vaccines for cancer!) or are for the same disease.

Even more importantly though, removing non-medical vaccine exemptions, which are often abused, doesn’t force anyone to vaccinate their kids.

Vaccine mandates are laws about getting vaccinated to attend daycare and school, etc. You still have a choice if you don’t want to get vaccinated.

What’s the problem that some folks have?

They don’t like their choices!

They want to be able to skip or delay their child’s vaccines and be able to send them to daycare or school.

“…the increased risk of disease in the pediatric population, in part because of increasing rates of vaccine refusal and in some circumstances more rapid loss of immunity, increases potential exposure of immunodeficient children.”

Medical Advisory Committee of the Immune Deficiency Foundation

And they want to take away everyone else’s choice to decrease their risk of getting a vaccine-preventable disease.

You don’t have a right to do that though!

Are you still spreading anti-vaccine propaganda?

Then you are part of the problem. You just don’t realize it yet.

And you are the reason that rates of vaccine-preventable diseases are going up and why Legislators are having to tighten the rules to prevent exemption abuse.
