Overview
Complications
Methods of exposure prior
to the vaccine
Description of the vaccinebenefits and risks

this information is relevant
Argument for the use of the
Varicella vaccine from
personal experiences
About Varicella






Comes from the Varicella Zoster Virus
Varicella (chicken pox)- childhood
Herpes Zoster (shingles)- late adulthood
Chickenpox: fluid filled skin lesions that scab, crust over, and fall off
Treatments: home remedies such as oatmeal baths, covering children’s
hands so they won’t itch, or using lotions
Academic concerns: students typically miss 5-6 days
My Case




Kindergarten class
outbreak
10 bumps
Did not know if it was a
mild case or something
completely unrelated
Pediatricians thought
that I would be likely to
get it if exposed to it
again
Kindergarten
Chickenpox Parties




Also known as exposure parties
Parents would exposure their child to one
with chicken pox so they would get the virus
at a younger age.
Common before vaccine
Raises concern about willfully spreading
infectious diseases
My “parties”



Brother had a typical
case
Neighborhood friend
had a cousin who was
invited to come to the
park
Did not develop
chickenpox
My brother at the age he had the virus
Fun times at Crowe Park
Complications




Rare severe complications
Adults and adolescents, pregnant women
fetuses, newborns, infants, and people with
compromised immune systems at risk
Complications: infections, high fevers,
dehydration, vomiting, diarrhea, encephalitis,
pneumonia, Reye’s syndrome etc.
Can result in hospitalizations or death
Why I was at risk?



Not sure that I ever had
the chickenpox
Parties unsuccessful
Close to adolescence.
My mother, a nurse,
was concerned about
me getting it when I
was older
The development of the vaccine






Developed in Japan in 1974
US since 1995
Live attenuated virus
Prevents chickenpox in 70-90% of people (mild
case)
MMRV (measles, mumps, rubella, varicella) vaccine
Most states including North Carolina now require it
for entering daycare and kindergarten
Pros




Shingles are less common
with vaccine
Less hospitalizations since
vaccine
If people develop
chickenpox approx. 50
lesions (typical wild case
300-500)
More cost effective (cost of
vaccine versus cost of
hospitalization)
Cons





People still can get Varicella
People who are allergic to
neomycin and gelatin may
develop allergic reactions
Adults may run a low grade
fever
Rash may develop (MMRV
vs. MMR or Varicella)
More research still needed
about long term immunity
My initial vaccination




Got the vaccine in 1996
11 years old
No symptoms
Was new vaccine but this would now be considered
a “catch up” because of my age
New developments


Recommend to be given in two doses (initial
with booster shot given 4-6 years later)
North Carolina requirements-1 dose if born in
2001 or later
Should I get another vaccine?



Microbiologist told me of recommendations of
another dose
I work in a preschool (not-state run) and
don’t have access to vaccination information
Discussed with my physician
Varicella Outbreak



Students in NC who are born before 2001 are
not required to have been vaccinated
Adults with shingles
Outbreak recommendations




Students-lesions crust (non-contagious)
Adults with Herpes Zoster-Antiviral medications
Vaccination (families, peers, 2nd dose)
Notification Letters to parents
An advocate for the Vaccine






Another dose
Didn’t develop any
symptoms
(Tetanus booster in other
arm the same day)
Soreness around Tetanus
shot but not Varicella
Older non-vaccinated
students coworkers with
shingles
Complications in
adulthood
Discovered from fiancé's
case that it recommended
when traveling abroad
Both Chicken pox free
due to Varicella Vaccine!
