Advocating immunization: how health professionals
can make a difference Scott
Wittet and Robert Aston offer some practical suggestions CHILDHOOD
vaccines save three million young lives per year. The World Bank has concluded
that immunization is one of the most cost-effective health interventions available
today and that improved health helps to reduce poverty and boosts national development.
Yet the realities of current immunization programmes often fall short of their
potential. If you and your staff are involved in promoting immunization in any
way, there are steps that you can take to help overcome the common problems. You
can advocate for stronger and better immunization programmes. You can advocate
for the introduction of new and under-used vaccines against major threats to public
health, such as hepatitis B and yellow fever. And you can inform yourself fully
about vaccine safety so that you can help parents who may be worried by media
"scares". Here are some suggestions: Learn
all you can about overall immunization safety
Become familiar with the evidence that immunization is a very
safe and cost-effective way to protect children against suffering, disease, and
premature death. If you do not have the time to investigate the literature yourself,
take advantage of the short summaries and briefing documents that are available
for healthcare workers on the web sites of reputable organizations in public health,
such as the World Health Organization, the U.S. Centers for Disease Control and
Prevention (CDC), and others. If web access is difficult, write to the organizations
public information offices to request paper copies of documents. For
general information for health professionals on the benefits of immunization:

Learn about
your local immunization programme Try
to determine how "healthy" it really is. Are children being fully immunized and
are they receiving the vaccines at the right age? Are the injections safe? Has
the risk of accidental needle-sticks been minimized? Is the cold chain adequate?
Is there adequate surveillance of vaccine uptake, adverse events, and disease
incidence? Are public relations and health education efforts effective? Is there
a working system to counter anti-vaccine rumours and misinformation? If not, alert
those in charge of the programme and urge them to make some changes.
Reputable sources on injection safety and the implementation of safety surveillance
include: - The Safe Injection Global Network
(secretariat based at WHO, address as above):

- Relevant papers in a special issue
of the Bulletin of the World Health Organization devoted to immunization
safety:

Know your local disease
burden If you think that hepatitis
B or Haemophilus influenzae type b (Hib) disease are problems in your area,
find out what is known about the disease burden. Contact your health authorities,
the WHO representative, and the local UNICEF office. Determine if there are research
projects in which you could participate or that can share relevant data. Investigate
what is known about the burden of these diseases in neighbouring countries.

Crucial contact: healthcare workers have a duty to give informed
advice to parents |
| Fight ignorance and misinformation
As the success of immunization programmes
reduces the immediate threat of disease in some countries, it is increasingly
common to find individuals and groups who criticize immunization and claim that
it is harmful. For example, anti-immunization groups have recently revived claims
of a link between the combined vaccine against measles, mumps and rubella (MMR)
and autism. There is to date no evidence of a causal relationship
between the vaccine and autism, but many parents have been worried by what they
have heard. They have a right to accurate and informed advice from their healthcare
workers. | - For
help in responding to parents concerns, see the CDCs website for a
briefing on this topic, with links to other resources:

- For briefings on other current "hot
topics" on vaccine safety in the media, see:

In general,
be sceptical about rumours and sensational media reports claiming dangers from
modern vaccines; they may be based on misinterpretation of the evidence. As the
feature on rotavirus vaccines on pages 3 to 6 of this issue shows, vaccine safety
concerns that are genuine are promptly publicized.
Remember that vaccines are far safer than the diseases they prevent. Severe adverse
effects of vaccines are very rare. The diseases themselves are much more likely
to harm children. Remind colleagues and patients about the horrors of those diseases.
Counter allegations of vaccine-damaged children with reports of disease-damaged
children. Dont sit on the fence
Health professionals do not help parents if they
simply hand out brochures or articles and expect people not trained in medicine
to make sense of confusing, and sometimes contradictory, data. Healthcare providers
are trained to form balanced, evidence-based judgments and to share their recommendations
with patients. Doctors or nurses who do not assist patients with healthcare decisions
may be shirking their responsibilities. If you believe in the value of immunization,
say so. Discuss, publish, teach, advocate
Write articles for the local newspaper. Make yourself available as a guest on
radio and television programs. If vaccine-preventable diseases are in the news,
use the opportunity to call for increased political commitment to immunization.
Discuss your concerns with government officials. Introduce yourself to programme
managers at UNICEF and non-governmental organizations such as Save The Children
or Médecins Sans Frontières. Become active in national paediatric
and medical associations and encourage them to formally recommend use of new vaccines
against diseases that are major public health problems.
Sustain
the momentum Emphasize that vaccination is
necessary even when disease levels diminish in your community. Global travel is
now so common that infections can be spread between continents in a day. Not until
a disease has been eradicated worldwide can immunization against it be discontinued
safely. Only smallpox has been eradicated so far, and that was achieved through
continuing, and thorough, immunization.
Global immunization is the greatest public health success in history. In little
more than a decade, a massive effort raised coverage rates from 5 per cent of
children worldwide in the late 1970s to a reported 80 per cent in 1990. But as
new health issues were given priority, some of the energy and excitement about
immunization dwindled. Fortunately, that trend is now being reversed.
You can be part of the process. It may seem
that immunization issues are being addressed at the national and international
levels. But change often comes from the community, and public demand for stronger
immunization programs can influence public policy. That demand can be encouraged
by individuals, single voices, persistently making themselves heard, then joining
with others to create a chorus that cannot be ignored.
