This is certainly not a “new” vaccine;  the H1N1 vaccines are just like the regular seasonal vaccine, made by the same manufacturers, who use the same egg-culture process.  There’s a different flu virus inside, but that’s little different than the “new” seasonal flu vaccine that comes out each autumn.

Side effects?  I’ve heard of no reactions from my patients so far, other than occasional 1-2 days of fever.  So there’s no reason to be more fearful of the Swine Flu vaccine than any other routine immunization.  (Click here to visit my post last month about the safety of flu vaccines.)

It’s unfortunate that there’s so much noise and misinformation about flu vaccines.  Much of it stems from recent political activity from groups who oppose universal vaccination.  (Click here to see my thoughts about that issue.)

But the facts are plain.  Thousands of people die each year from influenza.  The CDC reports that 324 Americans have died from Flu since April (as of 2/10/10), including 260 children.  (Click here to see the data.) Thousands more have been hospitalized.

But I’m not aware that anyone ever died from a flu shot.  The balance of safety is certainly convincing: we’re all better off getting vaccinated!

We’ve only received 100 doses of the shot for infants and toddlers so far.  We hope to have further shipments soon, so that we can vaccinate everybody, but it’s possible we’ll run out temporarily.  Remember that you need 2 doses (at least 3 weeks apart) for the best immunity (estimated at 85%), but the first shot gives some useful protection (estimated at 75%).  So we’ll try to give everybody the first dose before we start giving boosters.  Once we have received enough vaccine, we’ll start administering the boosters.

We have also received a second shipment of the H1N1 shot for older kids (with preservative).  So now we have enough H1N1 vaccine to vaccinate all our high-risk patients for their first vaccine.  If your child has asthma (or other high risk illness), you should be on our schedule now to receive the first dose.  I’ll post a note here when we have enough for boosters.  We now have enough seasonal flu vaccine for all our patients as well; all kids should be given both.

To give you some perspective, Delaware Modern Pediatrics has received only 300 of the 2300 doses of H1N1 we ordered for our patients.  Obviously, supplies are still tight.  This is not the fault of the Division of Public Health; the manufacturing process for flu vaccine is antiquated and slow.  We have similar supply problems with the seasonal flu vaccine in most years (though not this year); but the shortages haven’t been as noticeable because demand for flu shots has never been this high.

Should you have your kids vaccinated through school?  Yes, absolutely, if you can!  The only exception is for kids with asthma (or other serious underlying disease) who are being offered only the nasal flu vaccine at school; those patients should be given the injection (available through our office for our current patients).

The vaccine we have received is a shot.  It’s the type “with preservative.”  If your child is able to receive the Swine Flu vaccine from another source, such as your school, I strongly encourage you to do so!  The only exception is if the school’s vaccine is the nasal “Flu-Mist” type, which is a live virus, which would be contra-indicated for kids with chronic conditions such as persistent asthma.

So, regrettably, we still can’t schedule flu shots for kids not on the high-risk list.  I still expect to receive further shipments of H1N1 vaccine – and I expect that we’ll be able to vaccinate all our patients by the end of the flu season!  I’ll post a note on the blog here, when we receive enough to vaccinate everybody.

Should you sign your child up?  Yes!   If the school is ready to give your child a flu vaccine, I recommend that you participate.   We expect to have the vaccine in stock also, but I don’t know when it will be delivered.  If you’d prefer that we administer it instead of your school’s nurse, we’ll be happy to help.  (I’ll post a note on the blog when we get it in!)

The Swine Flu nasal vaccine probably will be delivered before the injections.  The live nasal flu vaccines are perfectly appropriate for any child over 2 years old, if they don’t have asthma (severe enough to have 4 attacks a year or more, or needing daily asthma medication.)

If we were not able to give your child (under 2) seasonal flu vaccine because we were out of stock for the past couple of weeks, you may now call to make an appointment and get caught up!  I encourage everybody to get vaccinated!

–  David Epstein, MD

For patients with “Commercial” insurance (Blue Cross, Aetna, Coventry, etc.): we have all “regular flu” vaccines:
-  shots for all children under 3
-  nasal spray for all children over 2 (EXCEPT those with asthma)
-  shots for all children over 3 (INCLUDING those with asthma) (This is *new!* as of 9/25/09; so if we delayed giving flu vaccine last month because your child has asthma, NOW you can call us to schedule a flu shot.)

For patients with “Medicaid” insurance (Delaware Physician’s Care, Unison, etc.):
-  We have flu vaccine ONLY for patients over 8 years old (healthy or asthmatic).  I will post a note here when they are delivered; we hope to have them by Halloween.

“Swine Flu” (Novel H1N1) vaccines:  As of 10/7/09:
-  NO vaccines yet.  They will be delivered in shipments spread across many weeks.  The CDC is just starting to distribute Swine Flu vaccine to hospitals.
-  Eventually we will have both nasal vaccines and injections
-  “High Risk” patients will be vaccinated first
-  I will post a note here when they are available, we hope by Halloween.

We are able to immunize most of our patients against “seasonal” (regular) flu.  We have been immunizing kids under 3 with flu shots since mid-August.  We are also able to immunize most kids over 2 with the nasal “FluMist,” except kids with asthma; we can give them flu vaccine injections.

Separate vaccinations against both regular flu and Swine Flu are needed for the best protection.  I strongly recommend that all patients receive flu vaccine, both “seasonal” and H1N; parents should also be vaccinated if possible.

Currently, physicians are being asked to “prioritize” testing for the H1N1 flu virus.  In general, we are advised not to run tests unless the patient is sick enough to consider hospitalization.  If we test everyone with fever, the labs will be overwhelmed, which will delay really sick patients from getting test results.  Also, not every case of Swine Flu must be treated with Tamiflu.  There is concern that overuse of antiviral medications like Tamiful may induce the Swine Flu virus to mutate and develop resistance.

Some patients have asked about taking the children out in public.  But I don’t think it’s necessary to “huddle” at home.  Only a general curfew would be effective at curbing transmission; most people who contract flu (H1N1 or regular) will recover anyway; and in the meantime we have to live our lives.  Kids need social stimulation too!  Frequent hand washing (or hand sanitizer) is your best protection.

So far, Swine Flu hasn’t seemed very serious.  Most cases have recovered fully; fewer than 500 people have died from it in the US so far this year.  This is a remarkably low number, considering the high rate of transmission.

But the concern is that if the Swine Flu virus mutates into a more virulant strain, but retains its high contagiousness, things could get much worse.  This is what happened during the 1918 pandemic of H1N1 flu, which killed 100 million people (5% of the world’s population).

Our medical care is certainly better than it was in 1918, and we hope that another pandemic like 1918′s would not be as lethal.  We now have antiviral medications, better hospitals, antibiotics, and better worldwide communications.  But we are not completely protected:  strains of Swine Flu resistant to antiviral medications have been reported.  And many people in the world have never seen a doctor and can’t get to a hospital at all!

I recommend that everyone get a flu vaccine.  Adults should get them, for their own protection and so that it doesn’t spread to the kids.  Kids should get them, for their own protection and so it doesn’t spread to their friends and classmates.

Flu shots are routinely given to kids 6 months and older.  (Nasal spray vaccination is a nice alternative for kids over 5 years old who don’t have asthma.)  Two vaccinations, one month apart, are required if you’ve never had flu vaccine; one vaccine per year is required after that.  This year, vaccine against Swine Flu will be administered separately; we probably won’t get ours in stock until Thanksgiving according to the Delaware Division of Public Health.

Never had a flu shot?  This year is a good time to start!  Afraid of the flu vaccine?  There’s no reason to be; people who claim that the “flu vaccine made me sicker” are usually confused by a coincidental illness unrelated to the flu vaccine.
