Sizing
up Smallpox Vaccine

SIZING
UP SMALLPOX
Question:
I thought we got rid of smallpox in the 1950s. What’s
with this talk of vaccine?
Answer:
The last case of smallpox (AKA variola virus) in the USA
was in 1949. In 1977, a Somalian man was the last person
on earth to ever suffer from the disease. Smallpox has
no natural host other than humans. You won’t catch
it from animals or bugs. Man-made laboratory stockpiles
loom on as the sole source of smallpox virus.
Question:
I’ve heard that smallpox is always fatal and definitely
ugly, so I want to get the vaccine right away, just in
case.
Answer:
According to the Centers for Disease Control, the smallpox
virus commands a fatality rate of just 30%. This means
that most people who contract the illness will survive.
In the event of bioterrorism, there’s sufficient
smallpox vaccine to protect everyone in the country.
Question:
Good, then since we have enough, I’m going out for
the shot this instant.
Answer:
Wait! Right now, the only people receiving the vaccine
are health care workers volunteering for the Massachusetts
Smallpox Response Team and certain military personnel.
The Massachusetts Department of Public Health & the
Smallpox Working Group of the Statewide Bioterrorism Task
Force determined this distribution as part of the pre-event
vaccination plan.
Question:
Come on. We’ve got enough vaccine, let’s protect
everybody. Israel didn’t have a problem with it.
Answer:
The Israelis immunized their military with a different
strain of smallpox vaccine than ours. Theirs is the Lister
vaccine. It won’t give you fresh minty breath, but
it does elicit fewer side effects than our supply. The
bi-monthly Massachusetts Nurse calls our smallpox vaccine
the most dangerous inoculation ever invented. This vaccine
contains the live virus, vaccinia, a close relative to
smallpox. Historically, 15 people per million inoculated
developed serious side effects. Two people per million
died.
Question:
My word! Just warn me about the minor side effects for
now.
Answer:
According to the CDC, standard responses to the vaccine
include a sore arm, fever, and body aches. The Massachusetts
Nurse cautions about additional reactions including swollen
underarm glands and generalized malaise disturbing all
regular activities including sleep.
Question:
That’s it?
Answer:
Those were the safer side effects. More serious reactions
can occur. Touching the open sore at the vaccination site
and then touching another part of your body can lead to
a localized “vaccinia rash”, typically affecting
the gonads or the eyes. Blindness can result. If the virus
seeds in the bloodstream, open sores afflict the whole
body. Finally, the dreaded allergic Erythema multiforme
can emerge. The CDC estimates that 1000 people per 1 million
vaccinated will experience these serious reactions.
Question:
That’s a lot. What about those fatal reactions you
mentioned?
Answer:
The Massachusetts Nurse divides these fatal reactions
into 3 categories: Swelling of the brain (encephalitis),
destruction of the skin leading to death, and eczema vaccinatum,
disastrous skin rashes. Anywhere from 14-52 people per
million vaccinated will experience these life threatening
emergencies.
Question:
Is there no telling who will fare well and who we’ll
farewell?
Answer:
So far, we do know that certain populations, like pregnant
women and babies, are more prone to harboring severe,
life threatening responses to the vaccine. Forego the
vaccine if you’ve ever had eczema or atopic dermatitis.
Immunosuppression caused by cancer, substance abuse, organ
transplantation, HIV/AIDS, anorexia, or steroids also
precludes inoculation, unless exposed to smallpox. Smallpox
itself is more hazardous than the smallpox vaccine, even
for those in a high risk category. Do you have any other
questions about the vaccine?
Question:
Yes. Do they make a bubble with it or do they stick it
in your arm?
Answer:
Neither. The smallpox vaccine currently employs a 2-pronged
needle. The vaccine-coated needle repeatedly pricks a
tiny patch of skin to form a small sore.
Question:
Gross! They use the same needle over and over again! Is
that safe?
Answer:
It’s dubious. The needles selected for smallpox
vaccine administration do not pass muster with the Needlestick
Safety and Prevention Act of 2000. Consequently, there
exists an unnecessarily high risk of needlestick injury
to the inoculating Nurse. Needlestick injuries can cause
bloodborne illness such as Hepatitis or HIV. Adhere to
strict post-vaccination care guidelines because the inoculation
sore has the potential to spread vaccinia to others and
to self. The vaccination site starts as a bump, fills
with pus, blisters up, and eventually pops.
Question:
So there are problems with the vaccine. For all these
drawbacks, the thing better work.
Answer:
Yes, the vaccine is deemed 95% effective for 3-5 years.
After 5 years, immunity starts to wane.
Question:
What about duct tape?
Answer:
Adds rough elegance to torn parkas purchased during Y2K.
