Federal health officials are investigating the first hints of any possible significant complications from the H1N1 vaccine, but stressed that the concerns will probably turn out to be a false alarm.
The latest analysis of data has detected what could be a somewhat elevated rate of Guillain-BarrĂ© syndrome, which can cause paralysis and death; Bell’s palsy, a temporary facial paralysis; and thrombocytopenia, which is a low level of blood platelets, officials reported Friday. The data is being collected through five of the networks the government is using to monitor people who were inoculated against the swine flu.
Officials stressed that it is far too early to know whether the vaccine was increasing the risk of those conditions or whether there is some other explanation, such as doctors identifying more cases because of the intensive effort to pinpoint any safety problems with the vaccine.
