Vaccines with Diluents

Many vaccines come either in prefilled syringes or ready to use multi-dose vials.

The MMR vaccine is mixed with a diluent (sterile water) before it is administered.
The MMR vaccine is mixed with a diluent (sterile water) before it is administered.

Others are freeze dried and need to reconstituted or mixed with a specific diluent, such as sterile water.

Vaccines with Diluents

Those that use a diluent include:

  • MMR II
  • ProQuad
  • Varivax (chickenpox)
  • Zostavax (shingles)
  • ActHib and TriHIBit (Hib)
  • Hiberix
  • Menveo and Menomune (Meningococcal)
  • Pentacel
  • Rotarix
  • Imovax and RabAvert (rabies)
  • YF-VAX (yellow fever)

In addition to sterile water, vaccine diluents can include sodium chloride, distilled water, and vaccine antigens.

Unfortunately, the use of diluents can lead to errors when administering vaccines, from using the wrong diluent, using a drug instead of a diluent, to giving a diluent instead of a vaccine.

That’s what happened when 15 children in Syria died after being vaccinated with MMR. The drug Atracurium was used instead of the diluent for the MMR vaccine.

It is also what happened to the children in Samoa.

And that’s why people who give vaccines are taught to “Check the vial label three times to be sure you have chosen the correct vaccine product (and diluent, when applicable). Check the expiration date of the vaccine (and diluent) before using to be sure they are not out of date.”

Neomycin in Vaccines

Some vaccines do contain very small amounts of antibiotics “to prevent the growth of germs (bacteria) during production and storage of the vaccine.”

These antibiotics can include neomycin, gentamycin, polymyxin B, and streptomycin.

Neomycin in Vaccines

Although allergies to antibiotics are not rare, the presence of antibiotics in some antibiotics has never been found to cause severe allergic reactions in kids who get vaccinated.

And in many cases, the antibiotics are actually removed from the final vaccine or only remains in residual amounts.

Are your kids allergic to neomycin or any of the other antibiotics in vaccines? Talk to your doctor before they get vaccinated.

Fortunately, commonly used antibiotics, like amoxil and zithromax, aren’t used as ingredients in vaccines.

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.

Stabilizers in Vaccines

Some vaccines contain stabilizers “to help the vaccine remain unchanged when the vaccine is exposed to heat, light, acidity, or humidity.”

Stabilizers in Vaccines

These stabilizers might include monosodium glutamate (MSG), glycine, gelatin, 2-phenoxy-ethanol, lactose, sucrose, or human or bovine serum albumin.

None of stabilizers are toxic or dangerous.

They include amino acids, sugars, and proteins.
