Next Season’s Influenza Vaccine

March 5th, 2013

Just as our influenza season winds down (and it is), it’s time to plan for the next one.  Every February the World Health Organization convenes a panel of experts to look at the most current data on the circulating flu strains from around the world and makes recommendations for the next season’s Northern Hemisphere flu vaccine.  At this week’s meeting in Geneva, the group recommended changing a B component of the vaccine, but sticking with the A/H3N2 and A/H1N1 components for next year. 

It may seem too early to be thinking about next year’s flu vaccine, but planning in February allows time for vaccine companies to grow the viruses and process the vaccine. The vaccine-making process still takes about 6 months… so it’s important to start as early as possible to ensure that vaccine is available for the start of the next flu season. Getting vaccinated against the flu every year is important, especially because the vaccine strains can change from year to year, as will happen for the 2013-2014 season.

Influenza Still Increasing in AZ

January 25th, 2013

Yesterday afternoon’s weekly flu report shows that influenza is still circulating widely in AZ…  with a steep increase in the last couple of weeks.  The strain that’s circulating is mostly Type A - H3N2 which can be more severe than the 2009 H1N1, especially for seniors. There are plenty of B strains going around too.  But you can still find a vaccine through Stop the Spread AZ – just be sure to call the place first to make sure they still have it and if you need an appointment.  By the way- this year’s vaccine is still a perfect match for the circulating strains.  The best prevention besides getting vaccinated is to wash your hands and make sure you cough or sneeze into your sleeve instead of your hand.  Most importantly…  don’t send your kids to school sick and don’t go to work sick either.

The Silent Breakthrough

November 26th, 2012

Until last week, influenza vaccine makers were limited to producing flu vaccines using a 40-year-old technology that depends on using fertilized chicken eggs to grow virus strains- meaning that it takes several months to make an influenza vaccine.  Makers needed to organize sterile egg supplies and incubate the virus in them before the vaccine could be made and delivered.  That’s why it took 6 months or so to develop the H1N1 vaccine during the 2009 pandemic.

Public health has known for a long time that relying on this 40-year-old egg-based technology poses a huge response and public health risk- especially if a severe pandemic strain were to break loose.  That’s why the US Department of Health & Human Services invested more than $1B in the development of a new cell-culture technology to develop the influenza vaccine.  A cell-culture technology will allow the public health system to make a brand-new influenza vaccine in a matter of weeks rather than months.

That investment paid off a couple of days ago- when the FDA  approved the first seasonal flu vaccine produced using cultured animal cells, instead of fertilized chicken eggs.  The vaccine is called Flucelvax and it’ll be available for people 18 and older.  The new vaccine isn’t in large scale production yet…  but it will be as soon as Novartis gets its manufacturing facility up and running.   

This breakthrough will also have another side benefit.  If you have an egg allergy and have always wanted to do the right thing for your community and get vaccinated for influenza, but couldn’t…  this new technology will allow your day to finally come.  Like I said…  it’s not widely available yet, but I’m sure it will be for next season. 

This new cell-culture technology will likely become the new standard for influenza vaccine production- and importantly- it adds an important layer of protection for pandemic readiness.

Flu Down Under- 2012

August 24th, 2012

The Southern Hemisphere has its flu season during our Summer- so every year around now we watch influenza activity “down under” to get an idea of what we might expect for our upcoming flu season.   Here’s the scoop right now.  Flu south of the equator has already peaked and continues to decline.  There’s been a lot of variation in the dominant viruses in each country this season.  Many South American countries have mostly had the H1N1 “pandemic strain” while others like Southern Africa, Australia and New Zealand all had a lot of influenza A (H3N2), with co-circulation of influenza B.  You can check out more on the World Health Organization’s main influenza website and the Australian Health Ministry’s surveillance website.  

The formula in this year’s US vaccine is a good match for what’s been circulating in the Southern Hemisphere so far this year (Influenza A H3N2 and H1N1, and influenza B).   Some of the manufacturers of the vaccine have already delivered some doses- and you’ll no doubt start seeing those “flu shots here” signs at a pharmacy near you shortly.

Flu Down Under

August 4th, 2011

This is the time of year that public health folks start watching the flu reports from the southern hemisphere.  We’re watching for a couple of things – the circulating strains and how it’s spreading.  The Australian Government Department of Health is reporting 6 times as many cases as they had at this time last season.  It could be an early season for them or it could be that it will end up being a blockbuster flu season for them.  The good news is that the circulating strains are all covered by the vaccine strains approved by the FDA last week –meaning that there aren’t any surprise strains going around (at least so far).  The H1N1 pandemic strain is dominant in Australia right now.

FDA Approves Vaccines for the 2011-2012 Influenza Season

July 25th, 2011

The FDA approved the 2011-2012 influenza vaccine this week. The strains in this year’s vaccine were recommended by the CDC and the World Healthy Organization after studying virus samples collected from around the world to find the influenza viruses that are the most likely to cause illness during the upcoming flu season.  The strains selected for this season are the same as last year: A/California/7/09 (H1N1)-like virus (pandemic H1N1 2009 influenza virus), A/Perth /16/2009 (H3N2)-like virus and B/Brisbane/60/2008-like virus. 

 People should get immunized against the flu every year- even when there’s no change in the strain from the previous year (like this time).  Immunity to influenza viruses declines over time and might be too low to provide protection after a year.

ADHS Aces the 2010 Strategic National Stockpile Test

September 21st, 2010

The Strategic National Stockpile is a national repository of antibiotics, chemical antidotes, antitoxins, life-support medications, IV administration, airway maintenance supplies, and medical/surgical items which are stored in a few locations around the country. The stockpile is designed to supplement public health agencies in case there’s a national emergency anywhere and at anytime within the U.S. or its territories. At the beginning of the H1N1 pandemic, Arizona  received and distributed hundreds of thousands of treatment courses of antiviral medication and other hospital supplies.  We turned around our supplies and shipped everything to their final destinations at the local health departments within 36 hours.

Each year the CDC comes out to “grade” our readiness by reviewing our plans, exercises, our execution during actual events (e.g. H1N1) and our after action reports.  This week, our project officer gave us a final grade of A+ or 97%.

Well done Preparedness Team.

The reviewer gave us glowing commendations for factors including leadership support, effective coordination and collaboration with the state/local/private sectors (Scott Voss & Kaitlin Henslee), and development and implementation of a multi-year Training and Exercise Plan (Andrew Lawless).  We already knew we were ready because we smoked the H1N1 stockpile distribution, but it’s nice to know that we’re still in crackerjack shape.

Seasonal Flu News

August 9th, 2010

The FDA approved this year’s (2010-2011) flu vaccine for the US.  This year’s shot will protect folks from 3 strains of influenza including the pandemic strain from last year.  The technical terms for the strains in this year’s shot are the “A/California/7/09 (H1N1)-like virus (i.e. pandemic virus”; the “A/Perth /16/2009 (H3N2)-like virus”; and the “B/Brisbane/60/2008-like virus”.  For the first time, the CDC is recommending that everybody over 6 months old get a seasonal flu shot.  The supply of vaccine should be robust- as there are now 13 brand names and manufacturers for this year’s vaccine, so if there is a problem with one of the suppliers (as was the case in 2004) it’s unlikely to create a major supply disruption. You can read more in the  FDA’s announcement this week.

 

Last week, the CDC’s Advisory Committee on Immunization Practices recommended that doctors avoid using the flu vaccine made by CSL Biotherapies (an Australian company) for kids under 8 years old because of unexplained  fevers in kids that got the vaccine over the last several months in Australia and New Zealand.

 

The pandemic flu strain (A/California/7/09 (H1N1)-like virus) pretty much completely displaced the H3N2 strain last flu season in North America.  However, the flu outbreaks that have occurred this summer (at summer camps, day care centers and sports camps and the like) have mostly been the A/Perth/16/2009-like H3N2 virus.  Both strains are included in this year’s seasonal flu shot.

ADHS Status

July 21st, 2010

We’ve got a lot to be proud of over the last year and an half.  It’s been hard, I know because of all of the budget reductions and the lower staffing level.  On the other hand, we’ve got an incredible mission and we’re doing a good job.  I often tell people that we work in the most interesting agency in state government.  Why?  Because we touch the lives of Arizonans in dozens of different ways everyday.  We:

 

  • Make sure that Arizonans are healthy and protected from infectious diseases like the flu and foodborne illnesses- and prevent diseases in the first place through our Vaccine for Children Program  

 

  • Provide families with young kids access to nutritious blend of foods www.azwic.gov.

 

  • Make sure that the kids at Child Care facilities are safe and sound and that they get some exercise thanks to our Empower Pack program.

 

 

  • Help save lives by doing things like developing Cardiac Arrest Centers and Primary Stroke
    Centers across the state that are dramatically improving outcomes for folks that have a cardiac arrest or a stroke and are leading the national shift to continuous chest compression CPR from the old compression/breathing method .

 

  • Are building a new Trauma System from the ground up- which saves lives every day.

 

  • Are leading the state’s anti tobacco efforts like the prevention activities in our youth tobacco campaign (called Venomocity)  and helping thousands of Arizonan’s Kick the Habit through our www.ashline.com services.

 

  • Are improving the performance of the state’s mental health system by giving choice and voice to folks with mental health and substance abuse needs- improving their ability to better participate in their path to Recovery from  Mental illnesses.  Over this past year, we have developed the new Nine Adult Guiding Principles to compliment our Children’s 12 Principles. We developed an RFP, went out for bid, and issued awards for all Geographic Service Areas outside of Maricopa County. We also planned for and implemented the most severe budget reductions in the behavioral health system in Arizona’s history.

 

  • Make a difference in hundreds of peoples lives at the Arizona State Hospital-  by helping them in their road to recovery by treating them with dignity, care and respect.

 

  • Run one of the state’s most well respected public health laboratories- providing the backbone for Arizona’s public health system.  For example, we find hundreds of kids with metabolic disorders and hearing and helped their doctors conduct interventions to help them avoid serious complications from their condition through our newborn screening program. 

 

  • Administer the Office of Children with Special Healthcare Needs (OCSHCN) program, which includes the Children’s Rehabilitative Services (CRS) program.  CRS provides family-centered medical treatment, rehabilitation, and related support services for children under age 21 with qualifying chronic and disabling conditions such as congenital heart disease,  neuromuscular conditions, spina bifida, cleft lip, cerebral palsy, and many others.

 

  • Test 1000s of biological samples for all kinds of viruses and bacteria including H1N1, tuberculosis, West Nile virus, rabies, and literally dozens of other diseases so that counties and doctors can help slow the spread of disease and help people get better in our Public Health Microbiology program.

 

 

  • Ensure that hundreds of clinical and environmental laboratories across the state are doing things right and providing good results through our Laboratory Licensure & Certification program.

 

 

And that’s just a fraction of the incredibly interesting and important things that we do.  Do you have any doubt now that this is the most fascinating place to work in state government?

 

We’re successful at all of these things because of your commitment to the folks of Arizona and to each other.  It takes a wide range of help from everyone including our IT, Human Resources, Rules, Procurement, Auditing, Financial Services and other Operations Teams to make these things happen.

 

Thank you all for rowing in the same direction.  I really appreciate your can-do attitude.  Thanks…  and make sure that you take the time to thank the folks around you from operations that make this place tick.
