Many internet sources state:
If you take the H1N1 FluMist, you will in fact become a carrier of the H1N1 flu. Information on this drug states that you can and will shed the virus for up to 21 days. That means as you are visiting with your elderly family members, or shopping in the isles of your grocery store or sitting in church with young children and people with immune problems, YOU are going to be shedding the virus H1N1 germs.
Just as I have conceded to my fears of having my 9yo receive this FluMist vaccine. Concern for myself and elderly family gives further pause for fear of infecting others through my prevention efforts
. Especially considering planned family gatherings next week.
Is this more fear mongering?
I have heard the inverse to this message, that H1N1 FluMist recipients spread the weakened virus just enough to provide immunity benefits
From a small group study:
With documented transmission of one Type B in one placebo subject and possible transmission of Type A viruses in four placebo subjects, the probability of acquiring a transmitted vaccine virus was estimated to be 2.4% (95% CI: 0.13, 4.6), using the Reed-Frost model. |
The duration of FluMist vaccine virus replication and shedding have not been established.
Vaccine recipients or their parents/guardians should be informed by the health care provider that Influenza A (H1N1) 2009 Monovalent Vaccine Live, Intranasal is an attenuated live virus vaccine and has the potential for transmission to immunocompromised household contacts.
