H1N1 Vaccine Safety ‘Reassuring’ H1N1 Vaccine Safety ‘Reassuring’ H1N1 Vaccine Safety ‘Reassuring’

The 2009 H1N1 influenza vaccine shows “no increase above background rates” for complications like Guillain-Barré syndrome, according to preliminary CDC data released online in MMWR.

Counting all adverse events, the rate among recipients of 2009 H1N1 vaccine was higher — 82 per million doses, versus 47 for seasonal vaccine — but the percentage of those events that were considered serious was higher among seasonal flu vaccine recipients (6.1%) than among H1N1 vaccine recipients (5.4%).

Speaking at a news briefing on Friday, the agency’s director, Dr. Thomas Frieden, called the results “very reassuring” and said the likelihood of a repeat of the 1976 swine flu vaccine problems “is vanishingly remote.”

  1. Here in Toronto,when we try to report complications in ourselves or our staff to Public Health we are always told “that’s impossible’ and nothing is recorded. So how do we know there are no complications to the flu vaccine?Where are the double-blind studies on the effecteiveness of the flu vaccine? Over the course of a long career,I have heard thousands of patients tell me they got the worse case of flu a few days after the vaccine. I did not know what to say until in 2006 and again in 2007,i got severe influenza like illness for 5 days in bed. Last year,I did not take it. This year,I again got the flu and waste 7 days of work. When trying to report the complication I am told “Thats impossible”.So i guess the thousands of patients and myself are just dumb and uneducated.But I have concluded the flu shot is not science,it is religion. You believe or you don’t.well i no longer believe.And I think we should stop spendiong public money for something whose effectiveness has not been proven.

  2. Dear NEJM:

    Would you please advise me whether Dr. Duchastel’s remarks apply to the injected H1N1 vaccine or to seasonal flu vaccines or both? Also, does he implicate the US as well as Canada in lack of proven effectiveness of H1N1 injected vaccination?

    I encourage him and all others to continue pressing Public Health authorities in Canada for answers to important questions. It is critically important to public health to press for information and require meaningful dialogue to resolve issues based on evidence and its analysis, on science first.
