Antiviral Treatment

• ICU Admissions• 50% of pediatric ICU admissions received AV

treatment within 48 hours of symptom onset• 30% of adult ICU admissions received AV

treatment within 48 hours of symptom onset

• Deaths• 45% of pediatric deaths received AV treatment

within 48 hours of symptom onset• 20% of adults deaths received AV treatment within

48 hours of symptom onset

Invasive Pneumococcal Disease –Preliminary – CDC from 1 site

Antiviral Resistance

• DSHS and CDC are collaborating on resistance testing for novel H1N1

• A few confirmed Tamiflu resistant cases in Texas, associated with prophylaxis or use in persons with significant immunocompromise

• No confirmed resistance to Zanamivir/Relenza • All novel H1N1 viruses tested by CDC have been

resistant to amantadines, including those in Texas

• Use antivirals appropriately to decrease resistance development; trend is towards watchful waiting rather than prophylaxis after exposure

Vaccine Administration Intervals and Types

• Inactivated vaccine – seasonal and novel H1N1 – any interval or simultaneously

• Seasonal and H1N1 at same time– can give 2 inactivated or one inactivated and one intranasal LAIV; can also give at any interval between

• Interval between live (LAIV) vaccinations of any type should be 28 days but could be at least 21 days

• Novel H1N1 Vaccine types

• 3 injectable vaccines and one live attenuated influenza virus intranasal vaccine are in use in the U.S.

• One of the injectable vaccines (CSL) has been expanded for use from 6 months of age and up.

• FDA has just approved an additional manufacturer’s injectable for use in persons 18 years old or older.

DSHS Vaccine Allocation

• DSHS manages vaccine distribution in accordance with the recommendations of the CDC’s Advisory Committee on Immunization Practices (ACIP).

Priority Groups

• Vaccine has been made available for these priority groups:

• Pregnant women• HCW / EMS• Close contacts of children < 6 months of age• Children 6 – 59 months• High risk children 5 thru 18 years• High risk adults 19 thru 64

Once vaccine supply is sufficient, the groups will be expanded to the two remaining high risk groups--healthy children and healthy adults 19 – 25.

IN CHOOSING WHOM TO VACCINATE:PROVIDERS SHOULD USE CLINICAL JUDGMENT,

BASED ON THEIR EXPERIENCE AND SITUATION

Vaccine Supply as of Monday, November 16th, 2009

• Approximately 48 million doses available nationally

• 3.7 million doses made available to Texas

• Virtually all has been made available to providers

Number of Providers

• Pre-registered providers: 12,706

• Final registered providers: 11,055

• New provider registrations in ImmTrac: 3,482

Vaccine Ordering and Distribution

• H1N1 vaccine distribution relies on Texas’ successful public and private healthcare partnerships.

• State, regional and local public health recruited private-sector partners for H1N1 vaccine administration.

• Public and private providers registered at www.TexasFlu.org to receive H1N1 vaccine.

• The Vaccine Ordering and Reporting System (VORS) at www.TexasFlu.org manages vaccine allocation, ordering, distribution information, and reporting.

•Provider allocations are posted online in the Vaccine Ordering and Reporting System (VORS).

•Providers are notified by email and blast fax to place their orders for H1N1 vaccine in VORS.

•Providers place their order in VORS up to their maximum amount of available allocated vaccine.

•The Immunization Branch sends the orders to the distributors for shipment

•Distributor’s delivery time is 5 – 10 days

Vaccine Ordering & Distribution

Doses Administered Reporting

• Providers are required to go into VORS and report doses administered on a weekly basis• Total Number of doses administered are reported by age

group for the following ages:

• 6-23 months

• 24-59 months

• 5-18 years

• 19-24 years

• 25-49 years

• 50-64 years

• 65+ years

Reporting the Administration of the H1N1 Vaccineto ImmTrac

• ImmTrac is the Texas immunization registry• Serves as the tracking and reporting tool for Texas

community preparedness effort• Free service from the Texas Department of State Health

Services (DSHS) • Repository of immunization histories for

• Texas children• Texas first responders• First responder family members 18 years of age and

older• Disaster-related information

ImmTrac

Texas Administrative Code, Title 25 Part 1 Chapter 100 Rule § 100.7 & § 100.8

Allows for the inclusion of information about persons who receive antivirals, immunizations or other medications (AIMs) in preparation for, or in response to, a potential or declared disaster or public health emergency into ImmTrac

State Law Requirements

• As the reporting and tracking tool, ImmTrac will include information on all individuals who receive an antiviral, immunization or medication (AIM) in response to, or in preparation for, a public health emergency or disaster event (providers should notify each client receiving the vaccine of this information)

• Healthcare providers administering AIMs must report such information to ImmTrac

• ImmTrac will retain impacted individuals’ records for the mandated retention period of 5 years after the event has been declared over

• Opportunity to grant consent to remain an ImmTrac participant may be requested anytime prior to the end of the mandated retention period for any disaster/emergency (see Disaster Information Retention Form section)

How to Report Administration of the H1N1 Vaccine to ImmTrac

There are two (2) ways to report the administration ofthe H1N1 vaccine to ImmTrac*

1. Direct ImmTrac Online Application Entry

2. Electronic Reporting Interface Standard Import Data File Process Delimited File Format Excel Spreadsheet Template

*Providers who are unable to report to ImmTrac using any of the methods listed above may contact ImmTrac via email at ImmTrac@dshs.state.tx.us (please type Reporting to ImmTrac in the subject) or you may contact us via telephone at 1-800-348-9158.

Vaccine Safety

• Modern vaccine development: • Improved process for manufacturing vaccines• FDA must approve after testing on animals and

humans

• Method for developing H1N1 vaccine is the same as that used for seasonal flu• This method is both proven and safe• Made with much of the same ingredients for seasonal

flu vaccines

• Clinical trials for effectiveness and safety are still underway

• Ongoing monitoring after release - VAERS

Vaccine Adverse Event Reporting System (VAERS)

• Texas VAERS reports are sent to DSHS

• DSHS sends reports to the CDC

• CDC analyses reports and conducts investigations on VAERS reports

• CDC maintains national VAERS data

H1N1 Help Desks

• 2-1-1 Texas (877-541-7905 or www.211texas.org)

In addition to usual information and referral specialists, 2-1-1 is also staffed by nurses who respond to the public and healthcare providers on H1N1 clinical questions, VORS questions, and other H1N1 questions.

• DSHS H1N1 Vaccine Call Center opened 10-08-09 (888-777-5320 or VacCallCenter@dshs.state.tx.us)

Is staffed by Immunization Branch employees and temporary staff who respond to provider’s questions on vaccine allocation, ordering, distribution, and administration.

Responds to approximately 300 calls per day
