Measles case in the un vaccinated

A pure "oversight" for the MMR when the child had all other vaccinations seems a bit fishy to me. The parents, the physician, and the daycare would all have to miss it. I guess these things do happen.

1. i can imagine it does in a population as big as ours. nt

2. Yeah, "oversight" doesn't make any sense.

MMR is one that requires a booster. So that would be TWO oversights. Highly doubt it.

[chicagomd]

3. MMR requires a booster,

but not until 5-6 years of age, so the child in question would only need to have had one to be "up to date" on shots for most school requirements.

4. Now it looks like MMR needs TWO boosters

especially in adults..Heads up on a study that showed that a whole bunch of people who got mumps in that outbreak a couple years ago had two boosters. While I'm sure certain anti-vaxxers will misinterpret this, to me its *proof* of the damage unvaccinated people can do to the general population....

5. I got a third in college

We didn't have written proof upon arrival that I'd had the MMR so they jabbed me at the dorm. I've had autism ever since!

6. Despite what I have read here I was told by the pediatrician that you need a booster every 18 yrs

Tetanus every ten and MMR every 18. I never heard that it was supposed to be a lifelong protection. Maybe the measles is but not the mumps perhaps.

7. MMR contains all three live (but weakened) viruses.

When they induce an immune reaction, it is generally lifelong.

When this vaccine virus (a now modified form of the natural virus) is put back into the body, it grows very poorly. Whereas natural measles virus reproduces itself thousands of times during natural infection, the measles vaccine virus reproduces itself probably fewer than 20 times. That is why natural measles virus causes illness, but measles vaccine virus doesn't. However, because the measles vaccine virus reproduces itself a little bit, it induces immunity against measles that is life long.

8. Correct

Which is why technically the 2nd dose is not really a "booster", per say. Although it does look like a 3rd does might be necessary as per the mentioned the study above.

9. Many Vaccine Booster Shots Unnecessary: Study

Many vaccine booster shots may be unnecessary

The amount of protection that many vaccines offer is greatly underestimated and current vaccine schedules may need to be reevaluated, suggests new research in the New England Journal of Medicine.

The study, by Oregon Health & Science University researchers, finds that many people may be getting booster shots when their immunity levels may not require it.

The study's lead author, Dr. Mark Slifka, an associate scientist at the Vaccine and Gene Therapy Institute, notes that over-vaccinating the population poses no health or safety concerns; "it may just be unnecessary under certain circumstances."

The researchers evaluated blood samples from 45 study participants to determine the level of immunity in each individual for the flowing viruses:

Measles
Mumps
Rubella
Chickenpox (Varicella-zoster virus)
Mononucleosis (Epstein-Barr virus)
Tetanus
Diphtheria

They expected to find that an infection with one of the viruses would provide long-lived immunity against it, while a vaccination against one of the viruses would provide relatively short-lived immunity, said Slifka.

"Surprisingly, we found that immunity following vaccination with tetanus and diphtheria was much more long-lived than anyone realized," said Slifka.

What's more, immunity following infections with measles, mumps, and rubella was maintained several decades and in most cases, for life.

The research also reconfirmed a previous finding by Slifka and his colleagues that the duration of immunity after smallpox vaccination is much longer than previously thought. They demonstrated in this study that antiviral antibody response is maintained with a calculated half-life of 92 years.

That's substantially longer than the current estimate proposed by experts at the U.S. Centers for Disease Control and Prevention of three to five years of immunity.

In the case of tetanus, doctors are told that vaccination is effective for 10 years, after which a booster shot is currently recommended. But the Slifka team found that once a person has received their primary series of vaccinations, they are likely to be protected for at least three decades.

Based on this data, Slifka's team suggests health authorities may want to consider adjusting some recommended vaccination schedules, to help extend limited health care resources.

He also notes his study does not diminish the need for vaccinations.

"We want to emphasize that proper vaccination is vital for protecting people against infectious disease," he said in a statement.

Many Vaccine Booster Shots Unnecessary: Study
HealthDay, November, 2007 by Robert Preidt

Americans may be over-vaccinated against some diseases, according to a study that found the duration of protective immunity for many vaccines is greatly underestimated.

That means many people may be getting booster shots even though their immunity levels are adequate, the researchers say.

Based on the findings, it may be necessary to reevaluate timelines for vaccinating and revaccinating Americans against disease, said the Oregon Health & Science University researchers.

For this study, they analyzed 630 blood samples from 45 volunteers to determine each person's level of immunity against measles, mumps, rubella, chickenpox, mononucleosis, tetanus and diphtheria over an extended period of time.

"The goal of this study was to determine how long immunity could be maintained after infection or vaccination. We expected to see long-lived immunity following a viral infection and relatively short-lived immunity after vaccination, especially since this is the reasoning for requiring booster vaccinations," Mark Slifka, ...
