Can immunizations be given individually?

Question 3 of A Parent’s Guide to Vaccines : A Conversation About Vaccines for New Parents

2015_11_3 Can immunizations be given individually square

Some parents may want to give one immunization at a time, but this option is not always available.

An individual vaccine can immunize against multiple diseases or even multiple strains of a disease, and breaking them down into separate shots isn’t always possible to do. Pharmaceutical companies often combine multiple antigens into their formulations either for convenience, or to increase the efficacy of the immunization.

  • Monovalent vaccines Immunize against a single microorganism or a single strain of a microorganism.
  • Multivalent vaccines Immunize against two or more strains of the same microorganism, or against two or more microorganisms.

When your child receives one injection, there could be multiple strains or vaccines in that one inoculation. For example, the pneumonia vaccine only protects against pneumococcal bacteria, but there are 7, 13, or 23 different strains of pneumococcus that the vaccine is intended to protect against, depending on which version of the shot received. Breaking these strains into different shots would make little sense because the strains are similar and separating them would entail dramatically increasing the number of injections required.

An example of a combination vaccine is the MMR. It is only one injection, but it is intended to protect against measles, mumps, and rubella. Because these are live virus vaccines for three very distinct illnesses, parents may express a desire to separate this shot into three different injections.

Internationally, the MMR vaccine can be separated into single components. For example, measles vaccination can be given without mumps or rubella. In the US, though, the measles vaccine is only available as a combination shot (MMR or MMRV).

Other vaccines are combined because one component, like the pertussis component of the DTaP, does not work as well if not combined. Although different variations are available for different age groups, the monovalent acellular pertussis is not available in the US, and diphtheria and tetanus components are given together worldwide.

In the United States, parents have limited options when it comes to separating some combination vaccines. For example, an individual measles vaccine or whooping cough vaccine is not available in the U.S. at this time. These immunizations are available as combination vaccines only.

Examples of vaccines that are offered as single, multiple or combined vaccines:

The problem with MMR is that it can give me as a grown woman arthritis . The risk is quite high, 26%. If the rubella part is taken out, it would cause no problem and I could get it. But if I can get arthritis for months, years or “rarely” for life? No.

My family has the same problem with the Rubella shot. We need the measles and mumps separate.

Can somebody start a petition please? I really want to give the MMR to my children but I want to space them out!

My English is horrible otherwise I would start a petition.

How do we promote access to the split MMR vaccine? Is this something that is a Congress leader question or a CDC question or a vaccine company question?

I’m not sure I would love if someone could start a petition. I have no idea how to do that. I want to give my son the monovalent measles vaccine.

That would be awesome if someone could start a petition. I definitely not giving my kids this combined vaccines.

This article compares the vaccines that combine ingredients to prevent infections from strains of the same bacteria to vaccines that combine completely different viruses. That is bad science to compare the two, and also bad writing. There is no good scientific reason for combining the vaccine for measles, mumps, and rubella in the US and not in other countries.
