Back-to-school season means it's time
for . . . a television commercial exhorting parents to vaccinate
their children against that potentially deadly disease, chickenpox.
A recently launched ad sponsored by Merck
features shots of a weeping rubber duck and several dejected-looking
stuffed animals while a female voice warns that "children
can die from the serious problems caused by chickenpox."
The TV spot and two companion print ads
are timed to coincide with the beginning of the school year,
a Merck spokeswoman said, because that's when parents are
most likely to have their children immunized to meet vaccination
requirements.
Twenty-nine states require proof that
children entering day care or school either have had chickenpox
or have been vaccinated against the disease, which kills about
50 American children and an equal number of adults annually.
For reasons that are unknown, chickenpox
greatly increases the chance of contracting toxic shock syndrome
or necrotizing fasciitis, more commonly known as "flesh
eating bacteria" as well as encephalitis and pneumonia.
Although a single-dose vaccine was approved
six years ago by the Food and Drug Administration, some pediatricians
have been slow to recommend it, in some cases because they
were not convinced it was
necessary.
Their reluctance has led many parents
to believe that chickenpox, which strikes about 4 million
Americans annually, is more a childhood nuisance than a public
health threat.
That is a notion public health officials
and the American Academy of Pediatrics have sought to dispel.
In the past year immunization rates have jumped by 10 percentage
points and now approach 68 percent of children under age 3,
according to Merck.
"Despite the fact that most of the
time this disease doesn't result in complications, you can't
tell which child is going to have a mild case and which child
is going to be the one who dies," said Jane F. Seward,
acting chief of childhood vaccine-preventable diseases at
the federal Centers for Disease Control and Prevention (CDC).
"A lot of pediatricians have never seen a child die or
even be hospitalized."
Every year, according to the CDC, about
11,000 Americans are hospitalized with serious complications
from chickenpox, which tends to be more severe in adults,
particularly those with compromised immune systems.
Saari doesn't think the ominous tone of
the commercial, produced by the advertising agency Foote,
Cone, Belding-New York, hypes the risk chickenpox poses. "I'm
thinking of kids I see in the hospital who without good medical
care wouldn't have made it," he said. In the past six
months in Madison, a community of 400,000 people, Saari said,
six children have been hospitalized for chickenpox and several
nearly died.
"Historically it's kids in school
or day care who bring the disease home," and that can
be particularly serious if the household includes an infant
-- the CDC recommends vaccination at 12 to 18 months -- or
an elderly person or someone receiving chemotherapy, Saari
noted. Chickenpox is among the most contagious diseases.
Unlike other vaccines that have been dogged
by questions about whether they trigger autism -- a concern
for which there is no scientific evidence, health officials
maintain -- the chickenpox preventive has not encountered
questions about its safety, Seward said.
Early concerns that a booster shot might
be required to ensure continued immunity have not been borne
out, according to Seward. It appears that a single dose administered
after a child's first birthday offers sufficient protection.
For children who have not had either chickenpox
or the vaccine, the CDC recommends immunization between the
ages of 11 and 12. After age 12, two doses of vaccine administered
one month apart are necessary.
