CDC Releases 2009 H1N1 Vaccine Schedules CDC Releases 2009 H1N1 Vaccine Schedules CDC Releases 2009 H1N1 Vaccine Schedules

Children aged 6 months through 9 years should receive two doses of 2009 H1N1 vaccine roughly 4 weeks apart, the CDC announced in MMWR.

The report details the differing age-range approvals for the manufacturers:

  • CSL’s vaccine is approved for use in people 18 years and older (one dose, IM);
  • Novartis’, for ages 4 and up (one dose, IM, except for children under 10, who get two);
  • Sanofi Pasteur’s, for ages above 6 months (one dose, IM, except for children under 10);
  • MedImmune’s, for ages 2 to 49 (one dose, intranasally, except for children under 10).

The injectable formulations are adjuvant-free and contain inactivated virus; the intranasal formulation contains live attenuated virus and shouldn’t be administered to children under 2, adults over 49, pregnant women, people with medical conditions that put them at higher risk for flu complications, and children under 5 who’ve had a wheezing episode within a year. All the vaccines contain egg protein, and the article’s table provides details on those containing mercury.

  5. I am a kidney transplant patient. My doctor is saying not to get the injectable vaccine because I may loose my new kidney.

    Is this true??

    Its been a year since my transplant.

    If I get the H1N1 virus, what drugs can they give me?

    Thank you.

  6. By the time the vaccine will be fully available the virus will be gone or we all will be immune or dead!

  7. I would like to thank the CDC centre for its concern regarding this pandemic disease , actually many viral pandemic diseases are dilema for the whole world .however , the new vaccination for 2009 H1N1
    I think is save like the seasonal infuenza vaccine ( and the most likely side effects like thethe seasonal infuenza vaccine , fever , soreness at the site of the injection ,,,,etc ).
    but I notice the population still not trust this vaccination .
    thans again

  8. Shortly,I will be a kidney donor to my identical twin (27 yrs. female) The recipient tested positive for H1N1 some 5 months ago at the time of her end stage Renal diagnosis. At that time, whilst in quarantine, she was treated with TamiFlu. She is presently undergoing H.D.
    Should I as a donor, be vaccinated against the H1N1 influenza? Tentatively, the transplant should proceed within the next 3 months. In view of the recipients history, should she be vaccinated also.
    Precise answers are difficult to come by from our caregivers.
    Any input would be greatly appreciated.

  9. I am also a kidney transplant patient. I have been working as a high school director and I feel myself in a high risk group. Up to now my doctors haven’t informed me well. So what do you advice ?
    Should I as a kidney transplant patient, be vaccinated against the H1N1 influenza?
    I have never vaccinated the seasonal infuenza in my life.
    It has been more than three years since my transplant.
    If I get the H1N1 virus, what drugs can they give me?

  10. I had a kidney transplant 11/08. Cr was steady a 1.0 post transplant, until I had a seasonal flu shot in Oct 09 Cr went up to 1.3 within one week. 4 weeks later I had the H1N1 flu shot (as highly advised by by entire team), within one week my Cr shot up to 1.9. I was admitted for observation. Highest Cr was 2.8. Biopsy done post solu medrol IV for 5 days showed ATN. (Unable to do the biopsy on initial admission due to Coumadin Rx for DVT and need to be converted to Heparin- delayed biopsy).
    Cr is now steady at 2.0 since mid December. So disappointing. Since then I have developed HTN, treatment is causing edema. Also now have Anemia and back on Aranesp injections.
    No other factors changed prior to flu shots. We can only hope the ATN will resolved and I never get the flu….I will never get another flu shot.
    I also have SLE and during my initial exacerbation of SLE/nephritis was after a flu shot (1975).
    When patients have gut feelings not to do something…believe them. I should have listened to my inner self and took my chances of getting the flu. Maybe I could have spared my kidney this hit.
