Study published in Pediatrics indicates children of
parents who refuse pertussis vaccination are at high risk
for the disease
The June 2009 issue of the journal Pediatrics
includes an
article titled "Parental Refusal of Pertussis Vaccination Is
Associated with an Increased Risk of Pertussis Infection in
Children." It was written by Jason M. Glanz, PhD; David L.
McClure, PhD; David J. Magid, MD, et al. The abstract is
reprinted below.
OBJECTIVE. The objective of this study was to determine if
children who contracted pertussis infection were more likely
to have parents who refused pertussis vaccinations than a
similar group of children who did not develop pertussis
infection.
METHODS. We conducted a case-control study of children
enrolled in the Kaiser Permanente of Colorado health plan
between 1996 and 2007. Each pertussis case was matched to 4
randomly selected controls. Pertussis case status and
vaccination status were ascertained by medical chart review.
RESULTS. We identified 156 laboratory-confirmed pertussis
cases and 595 matched controls. There were 18 (12%)
pertussis vaccine refusers among the cases and 3 (0.5%)
pertussis vaccine refusers among the controls. Children of
parents who refused pertussis immunizations were at an
increased risk for pertussis compared with children of
parents who accepted vaccinations. In a secondary case-control analysis of children continuously enrolled in Kaiser
Permanente of Colorado from 2 to 20 months of age, vaccine
refusal was associated with a similarly increased risk of
pertussis. In the entire Kaiser Permanente of Colorado
pediatric population, 11% of all pertussis cases were
attributed to parental vaccine refusal.
CONCLUSIONS. Children of parents who refuse pertussis
immunizations are at high risk for pertussis infection
relative to vaccinated children. Herd immunity does not seem
to completely protect unvaccinated children from pertussis.
These findings stress the need to further understand why
parents refuse immunizations and to develop strategies for
conveying the risks and benefits of immunizations to parents
more effectively.

Three measles cases confirmed in unvaccinated children in
Bucks County, PA
On May 26, the Bucks County, PA, health
department posted a
press release on its website announcing three confirmed
measles cases. The total number of cases confirmed this year
in Pennsylvania now stands at nine. Six cases were confirmed
in the Pittsburgh area in April.
A portion of the press release about the Bucks County cases
is reprinted below.
The Bucks County Health Department advises the public that
it is closely monitoring three confirmed measles cases in
the county--all of which are under control and limited to
unvaccinated individuals who were in close contact with each
other.
"There is no risk of transmission to others at this point
from these cases, which involve three individuals who were
unvaccinated," noted Bucks County Health Director Dr. David
Damsker. "The first case involves a school-age child. The
other two are directly related to the first case and all
three individuals have been isolated from their schoolmates
and the general population."
Dr. Damsker reiterated the importance of being vaccinated to
provide the best protection against the measles and other
communicable diseases. "There is no substitute for
vaccination, which has been proven to be safe and
effective," he added. . . .

MMWR publishes report on large-scale human exposures to a
rabid bat in Montana in 2008
CDC published "Human Exposures to a Rabid
Bat--Montana,
2008" in the May 29 issue of MMWR. Portions of the article
are reprinted below.
On September 29, 2008, the Ravalli County Public Health
Department (RCPHD) notified the Montana Department of Public
Health and Human Services (MDPHHS) of a large-scale human
exposure to a dead bat at an elementary school. On October
1, the bat was confirmed to be rabid, and on October 4,
MDPHHS requested assistance from CDC in evaluating persons
for rabies exposure. Of 107 persons assessed, only one
person (1%) was recommended for rabies postexposure
prophylaxis (PEP) in accordance with guidance from the
Advisory Committee on Immunization Practices (ACIP);
however, 74 persons (68%) ultimately pursued rabies PEP.
This report describes the incident and public health
response, and highlights the importance of unified risk
communication. After a potential large-scale exposure to
rabies virus, guidance from clinicians should be consistent
with ACIP recommendations to ensure appropriate use of
rabies PEP.
Incident Description
On September 28, a parent of two students at a Ravalli
County elementary school found a dead bat carried into the
house by the family cat. The bat carcass was placed in a jar
and stored overnight. On September 29, one parent
accompanied the children to school with the bat, and before
leaving school premises, removed the carcass from the jar
and presented it to eight different classrooms (one
kindergarten, four 5th-grade, and three 4th-grade
classrooms). Students and teachers in at least five
classrooms touched the bat, along with a few other staff
members of the school.
Later that morning, the school nurse notified RCPHD after
learning of the presentation. RCPHD subsequently advised the
parent to submit the bat for rabies diagnosis. That
afternoon, the parent took the bat carcass to an off-campus
soccer practice attended by students from the school. Some
of these children touched the bat. On September 30, the bat
was shipped to the Montana Veterinary Diagnostic Laboratory
(MVDL). On October 1, MVDL detected the presence of rabies
viral antigen in the animal's brain via direct fluorescent
antibody testing. On October 16, CDC identified the
implicated virus variant as one associated with the silver-haired bat (Lasionycteris noctivagans).
On September 30, while awaiting the results of the
laboratory testing, school officials sent letters home with
students enrolled in the five classrooms (kindergarten and
5th grade) where the teacher observed students touching the
bat. The letter described concern for potential exposure to
the rabies virus. School officials did not send letters home
to students enrolled in the three 4th-grade classrooms
because teachers did not observe any of these students
touching the bat. On the evening of October 1, school
officials telephoned households of students in the
kindergarten and 5th-grade classes with news of the positive
laboratory findings; voice-mail messages were left if no one
answered. The cat that had discovered the bat received a
rabies booster shot after a veterinarian confirmed its
current rabies vaccination status. The cat was observed in
the owner's home for 45 days and was reported to be healthy
at the time of this report. . . .
Editorial Note
Large-scale human contact with rabid animals requires
mobilization of substantial resources and involvement of
public health officials, as demonstrated by this incident, a
similar occurrence in New Hampshire during 1994, and a
multistate incident in 2007. These incidents typically
generate high public anxiety, which can lead to unnecessary
rabies PEP. This report differs from accounts of previous
large-scale human rabies exposures because it describes the
compliance with ACIP recommendations by persons who were
evaluated and counseled by public health officials.
During 2007-2009, the human rabies vaccine supply was
limited because of temporary suspension of production by one
manufacturer. To acquire rabies vaccine during that time,
clinicians were required to first consult with state or
local public health officials. MDPHHS requested CDC
assistance because of the anticipated challenges posed by
assessing and counseling so many persons in this incident,
especially during a time of limited vaccine supply.
Approximately one third of rabies large-scale exposures
occur in school settings, which also are ideal sites for
educational outreach to promote safe animal practices. Such
outreach should include messages that warn against contact
with wildlife (both dead and alive) and instructions on what
to do if an animal is found on school or home premises.
School policies that prohibit bats and other common rabies
reservoirs in classrooms are recommended to lessen exposure
risks. All animals suspected of being infected with the
rabies virus should be handled carefully and brought
promptly to public health officials for testing.
Risk communication is an integral component of a public
health response after potential large-scale exposures,
including those involving potential exposure to the rabies
virus. Many of the persons who pursued PEP in this incident
appear to have acted upon advice from community physicians
in preference to information provided by public health
officials. Clinicians can play an important role in ensuring
that only persons with exposure that meet ACIP criteria
receive PEP. Coordination among the medical and public
health officials involved in a response to a potential
large-scale rabies exposure is critical to ensuring the
delivery of a unified message to the public regarding the
appropriateness of PEP. Timely dissemination of ACIP
exposure criteria to local clinicians via the Health Alert
Network (HAN) or other communication tools might help ensure
that exposed persons receive advice consistent with
recommended public health practice.

IAC's laminated versions of the 2009 child/teen and adult
immunization schedules offer significant advantages over
paper versions. Place your order today and use them
throughout 2009!
IAC's 2009 laminated immunization schedules are a
must for
every immunization setting: from conventional health clinics
and private practices to walk-in shot clinics in workplaces,
pharmacies, schools, and other sites. IAC offers the
laminated schedules for two age groups. The child/teen
immunization schedule is for people ages 0 through 18 years;
the adult schedule is for those older than 18. Though both
are adapted from the immunization schedules that were posted
on the CDC website in January, the laminated schedules offer
these advantages over downloadable paper versions:
(1) Coated in thick plastic, the laminated schedules are
washable and will hold up to a year's worth of use as
teaching tools that providers in any immunization setting
can use to give patients and parents authoritative
information about the vaccines recommended for various age
groups. You can also use them as a handy reference to
consult at a moment's notice.
(2) For the second year in a row, IAC has added a
significant feature to the two laminated schedules. Each
includes a guide to contraindications and precautions for
the pertinent age group (i.e., the child/teen schedule has a
guide to contraindications and precautions for child/teen
vaccines, and the adult schedule has a guide for adult
vaccines). Healthcare professionals will find these guides
extremely valuable in making an on-the-spot determination
about vaccinating any patient they see in any immunization
setting.
The durable laminated schedules come complete with essential
footnotes and are printed in color for easy reading. Each
schedule has six pages (i.e., three double-sided pages), and
when folded, measures 8.5" x 11".
For specific information about the child/teen schedule, to
view images of it, or to order online or download an order
form, visit http://www.immunize.org/shop/schedule_child.asp
For specific information about the adult schedule, to view
images of it, or to order online or download an order form,
visit http://www.immunize.org/shop/schedule_adult.asp
Prices start at $10 each for 1-4 copies and drop to $6.50
each for 5-19 copies. Discount pricing is available for 20
or more copies. For quotes on customizing or placing orders
in excess of 999 schedules, call (651) 647-9009 or email
