UPDATE: CDC SAYS, "PLAN NOW: EXPECT FLU VACCINE SUPPLY DELAYS AND POSSIBLE SHORTAGES"
The Centers for Disease Control and Prevention (CDC) has released the following announcement:
Influenza vaccine manufacturers have told FDA and CDC to expect delays in flu vaccine shipments this flu season. In
addition, the possibility of a U.S. shortage of influenza vaccine for the 2000-01 season continues to be a
concern. CDC is urging all health care providers who provide flu vaccines to
their patients to consider ways to ensure their high risk patients receive vaccination if a severe
vaccine shortfall were to occur. CDC also encourages delaying adult mass influenza vaccination campaigns to
November (usually recommended for October through mid-November) to diminish the possibility
that these campaigns will need to be cancelled because vaccine is not available.
The amount of vaccine available is complicated by two important factors: 1) the yield for this year's influenza
vaccine A(H3N2) component appears to be lower than expected which limits the supply that can be developed in time for
this flu season and, 2) other manufacturing issues. The total amount of vaccine available for the influenza season
is uncertain at this time. Because of this uncertainty, CDC urges health care providers to develop contingency
plans to ensure their high risk patients receive flu vaccine. Both FDA and CDC are actively working with manufacturers to
determine how much and when vaccine will be available.
Regardless of the overall availability of vaccine this flu season, CDC emphasizes that health care providers should
vaccinate persons at highest risk of death from influenza and the health care workers who take care of
In the United States, 70 to 76 million persons (approximately 35 million persons aged 65 years or older;
33 to 39 million persons less than 65 years of age with high-risk medical conditions; and 2 million pregnant
women) are at high risk for serious complications from influenza infections, including
hospitalizations and deaths. For every age group, people with chronic medical
conditions are at higher risk. However, healthy 50 to 64 year olds are not at
any greater risk than healthy adults less than 50.
Currently, four antiviral drugs are approved by FDA to treat acute, uncomplicated influenza. Two of the drugs are
also approved for use in preventing influenza. However, these drugs are not a general substitute for
influenza vaccine and should not be used as such. The annual use of influenza vaccine is the primary means for minimizing
adverse outcomes from influenza virus infections.
Influenza Vaccine Recommendations for the 2000-01 Influenza Season Only
Annual vaccination against influenza is the best way to reduce hospitalizations
and deaths from influenza complications. These infections result in approximately
20,000 deaths and 110,000 hospitalizations per year in the United States.
- Organized influenza vaccination campaigns should be
delayed. Health-care providers, health organizations, commercial companies, and other
organizations planning organized influenza vaccination campaigns for the 2000-01
influenza season should delay vaccination campaigns until November. The purpose of this recommendation is to
minimize cancellations of vaccine campaigns and wastage of vaccine doses
resulting from such cancellations.
- Influenza vaccination of persons at high risk for
complications from influenza and their close contacts should proceed routinely during
regular health-care visits. Routine influenza vaccination activities in
clinics, offices, hospitals, nursing homes, and other health-care settings
(especially vaccination of persons at high risk for complications from
influenza, health-care staff, and other persons in close contact with persons at high risk for complications from influenza)
should proceed as normal with available vaccine. This is particularly important for young
children at high risk who are receiving influenza vaccination for the first
time and who require two doses of vaccine.
- Providers should develop specific contingency plans for
an influenza vaccine shortage. All influenza vaccine providers, including health-care
systems and organizers of vaccination campaigns, should develop a provider-specific contingency plan to maximize vaccination of
high-risk persons and health-care workers. These plans should be available for
implementation if a vaccine shortage develops.
- Influenza vaccine should be offered to unvaccinated
persons throughout the influenza season. Each season, many people who should be
vaccinated have not received vaccine by November. For these people, influenza vaccine
administered about November can still provide substantial protective benefits within 10 to 14 days after
vaccination. In many years, influenza activity does not peak until after December.
- Minimizing influenza vaccine waste is particularly
important. Influenza vaccine purchasers should not place duplicate orders with multiple
companies. This should minimize the amount of vaccine that is returned
to a manufacturer and discarded.
- In 2000, the Advisory Committee on Immunization Practices
(ACIP) broadened its influenza vaccine recommendations to include all persons
50-64 years. There is no change in this recommendation at this time. However, if a vaccine
shortage materializes, then it would be appropriate to vaccinate persons with high-risk conditions in this age
group rather than the entire age group. Healthy persons in the 50-64 year old age
group are at lower risk for serious complications than persons in this
age group with underlying high-risk medical conditions.
- Vaccine providers should keep in mind that pneumococcal
vaccine is recommended for many of the same people for whom influenza vaccine
is indicated. Use of pneumococcal vaccine could reduce some of the bacterial complications
of influenza infection.
- There are no new recommendations for the use of influenza
antiviral drugs. Even if an influenza vaccine shortage develops, CDC does not
support their routine and widespread use to prevent influenza because this is an
untested and expensive strategy that could result in large numbers of persons experiencing adverse effects.
- This fall a CDC website will provide information on where
to obtain additional influenza vaccine supplies. In addition, local or state health
departments may also have information on vaccine availability in local
