Vaccines have proven to be our most cost-effective health care
intervention, preventing millions of children and adults from
contracting debilitating, disabling and sometimes fatal infectious
diseases. Most children in Canada are routinely immunized against9
of these diseases under programs offered and paid for by provincial
governments. However, for 4 additional vaccines thoseagainst
meningococcal infection, pneumococcal infection, varicellaand
adolescent/adult pertussis there is no uniform approach:these
vaccines are offered in some provinces but not others(see News, page
5981), despite their potential to prevent
diseasesand their sometimes permanent complications, to avert
hospitaladmissions and to save lives.2
To those of us working in health care professions geared to
optimize the well-being of children, the strides made in thelast
several decades in providing access to vaccines seem tohave been
replaced by paralysis. In most provinces and territoriestoday,
parents of newborn children must decide whether to payfrom their own
pockets for the newer vaccines, or to let theirchildren run the risk
of contracting preventable diseases. Insome provinces this can
amount to $600 per child, an amountthat many families would find
prohibitive.
Canada stands apart from the United States, the United Kingdomand
Australia in having a fractured immunization program bywhich each
province and territory defines the list of publiclyfunded vaccines
and immunization schedules. Even the much-malignedUS health care
system provides varicella and conjugate pneumococcalvaccines to the
majority of children through the federally fundedVaccines for
Children Program or private health insurance schemes.At the 5th
Canadian National Immunization Conference, in December2002, experts
and policy-makers from across the country recommendedthat
immunization be a national priority, anchored in a workable
federal/provincial/territorial collaboration with strong federal
leadership.2 There are several obvious reasons
for this, themost important of which is that infectious diseases do
not respectprovincial or national boundaries. Only by immunizing a
verylarge proportion of people a feat that cannot be accomplishedin a parent-funded immunization program will we reapthe full
benefits of vaccination. Second, although new vaccinesare not cheap,
a national program of vaccine procurement anddistribution would
dramatically reduce per-unit costs and thesecurity of supply.
Vaccines are cost-effective compared withother health care
interventions, but their economics are mostfavourable when they are
delivered through organized, large-scaleprograms.
We recognize that, in Canada, health care is primarily a provincialor territorial responsibility and that some provinces have resistedfederal involvement in health-related areas. In addition, until
December 1998, when varicella vaccine was licensed for use inCanada,
the provinces and territories were doing a good jobof introducing
newly licensed vaccines to prevent childhoodmorbidity and mortality,
and of making sure their populationswere immunized. Federal support
has been limited to regulatingvaccine licensure and lot-by-lot
release, supporting the NationalAdvisory Committee on Immunization
and maintaining a small staffand budget to assist provinces and
territories in coordinatinglimited activities.
But, during the 1990s a time of cutbacks in health carebudgets
and a gradual weakening of public health in Canada3,4 provinces and territories began to delay adopting
newprograms such as vaccination against Haemophilus influenzaetype b disease and hepatitis B, which eventually were implementedin all provinces and territories. But provincial and territorialdisparities have grown since the licensure of vaccines to preventvaricella, meningococcal group C infection, pneumococcal disease,and pertussis in adolescents: in most provinces and territories,none or few of these vaccines are publicly funded. These disparitiesare likely to widen as even more new vaccines reach the Canadianmarket. The not-too-distant future holds the promise of a varietyof new vaccines against influenza, human papillomavirus, herpes
simplex, HIV, chlamydia, gonorrhea, group A and B streptococci,
rotavirus, herpes zoster, respiratory syncytial virus, parainfluenza,
hepatitis C and a variety of other infectious and noninfectious
diseases. We need a national strategy, national leadership and
national funding.
Canadians have long cherished our universal health care program.
We strive to make sure that all adults get treatment for diseases
such as hypertension and even for risk factors such as hypercholesterolemia.But when it comes to protecting children and susceptible adults
against much clearer threats to health, we as a nation havefaltered.
At present, only the rich can afford these effectivevaccines.
Underprivileged children, who are most at risk ofa severe
complication of infection and would benefit most fromnew vaccines,
are least likely to receive them.5
The National Immunization Strategy2 is a
masterpiece of collaborativeplanning and a model for
federal/provincial /territorial cooperationtoward improved health.
As an early step in current health carereforms, it offers an
opportunity for the federal governmentto demonstrate its leadership
in a role that will be deemedby most Canadians to be appropriate.
Decision-makers might fearthat it would result in a never-ending
demand for funding ofnew and increasingly expensive vaccines. But
this can be dealtwith by agreeing on criteria including economic
considerations for the assessment of new technology.
We must end the current provincial vaccination hodge-podge that
results in treating some children (and adolescents and adults)as
more precious than others. We urge you to act quickly toput into
place a national coordinated system of planning, procurement,
implementation, monitoring and evaluation. The status quo isa sure
recipe for chaos.
