"Dec. 3, 2012 -- The U.S. flu season is here -- the earliest start since the "moderately severe" season of 2003.
Just as in 2003, the nasty H3N2 flu bug is causing most cases so far.
"This could be a bad flu year," warned CDC"...
As for any vaccine, adequate treatment provisions, including epinephrine, should be available for immediate use should an anaphylactoid reaction occur.
Special care should be taken to ensure that the injection does not enter a blood vessel.
It is important to use a separate sterile syringe and needle for each patient to prevent transmission of hepatitis B or other infectious agents from one person to another.
As with other vaccines, Liquid PedvaxHIB may not induce protective antibody levels immediately following vaccination.
As reported with Haemophilus b Polysaccharide Vaccine36 and another Haemophilus b Conjugate Vaccine37, cases of Hib disease may occur in the week after vaccination, prior to the onset of the protective effects of the vaccines.
There is insufficient evidence that Liquid PedvaxHIB given immediately after exposure to natural Haemophilus influenzae type b will prevent illness.
The decision to administer or delay vaccination because of current or recent febrile illness depends on the severity of symptoms and on the etiology of the disease. The Advisory Committee on Immunization Practices (ACIP) has recommended that vaccination should be delayed during the course of an acute febrile illness. All vaccines can be administered to persons with minor illnesses such as diarrhea, mild upper-respiratory infection with or without low-grade fever, or other low-grade febrile illness. Persons with moderate or severe febrile illness should be vaccinated as soon as they have recovered from the acute phase of the illness.46
Instructions to Healthcare Provider
The healthcare provider should determine the current health status and previous vaccination history of the vaccinee.
The healthcare provider should question the patient, parent, or guardian about reactions to a previous dose of PedvaxHIB or other Haemophilus b Conjugate Vaccines.
Laboratory Test Interactions
Sensitive tests (e.g., Latex Agglutination Kits) may detect PRP derived from the vaccine in urine of some vaccinees for at least 30 days following vaccination with lyophilized PedvaxHIB;38 in clinical studies with lyophilized PedvaxHIB, such children demonstrated normal immune response to the vaccine.
Carcinogenesis, Mutagenesis, Impairment of Fertility
Liquid PedvaxHIB has not been evaluated for carcinogenic or mutagenic potential, or potential to impair fertility.
Pregnancy Category C: Animal reproduction studies have not been conducted with PedvaxHIB. Liquid PedvaxHIB is not recommended for use in individuals 6 years of age and older.
Safety and effectiveness in infants below the age of 2 months and in children 6 years of age and older have not been established. In addition, Liquid PedvaxHIB should not be used in infants younger than 6 weeks of age because this will lead to a reduced anti-PRP response and may lead to immune tolerance (impaired ability to respond to subsequent exposure to the PRP antigen).49-51 Liquid PedvaxHIB is not recommended for use in individuals 6 years of age and older because they are generally not at risk of Hib disease.
This vaccine is NOT recommended for use in adult populations.
