Statistics on human swine influenza vaccinations

11 Jan 2010

At least 4,972 doses of human swine influenza (HSI) vaccine were administered at Hospital Authority (HA), Department of Health (DH) and private clinics to target groups between 1pm on January 8 and 1pm today (January 11).

Of this number, 3,523 were administered at HA and DH clinics while the eHealth System received 1,449 vaccination reimbursement claims from private doctors. It is expected that some additional vaccinations already given by private doctors will be recorded in the eHealth System later.

The administered doses comprised 2,324 jabs for community-living elderly aged 65 or above; 1,316 for persons under 65 years with chronic illnesses; 84 for pregnant women; 352 for healthcare workers; 888 for children aged between six months and less than six years; and eight for pig farmers and slaughterhouse workers.

This brings to at least 124,587 the cumulative total of HSI jabs administered to target groups since the start of the vaccination programme on December 21.

One report of a serious adverse event with a history of vaccination has been received so far. The patient's clinical features are compatible with Guillain-Barre Syndrome. Investigation by the DH is underway. An expert panel considered that it was not possible to differentiate with reasonable certainty whether the relationship between the HSI vaccination and the patient's symptoms was causal or coincidental.
