Statistics on human swine influenza vaccinations

4 Feb 2010

At least 1,644 doses of human swine influenza (HSI) vaccine were administered to target groups at Hospital Authority (HA), Department of Health (DH) and private clinics as well as residential care homes during the 24 hours ending at 1pm today (February 4).

Of this number, 448 were administered at HA and DH clinics while the eHealth System received 252 and 944 vaccination reimbursement claims from private doctors and visiting medical officers to residential care homes respectively. It is expected that some additional vaccinations already given will be recorded in the eHealth System later.

The administered doses comprised 191 for community-living elderly aged 65 or above, 156 for persons under 65 years with chronic illnesses, one for pregnant women, 103 for healthcare workers, 276 for children aged between six months and less than six years, and 917 for residents of residential care homes.

The cumulative total of HSI jabs administered to target groups since the start of the vaccination programme on December 21, 2009 is now at least 162,758.

Meanwhile, the DH's Centre for Health Protection has received further information on the 67-year-old woman with history of HSI vaccination who was admitted to Kwong Wah Hospital (KWH) on January 15, complaining of limb weakness.

A CHP's spokesman, while reaffirming that the woman was not suffering from Guillain-Barre Syndrome, said updated information from the hospital suggested that the patient might be suffering from encephalitis. "Further investigation will be carried out to ascertain the cause of her illness," he said.

The woman is now in intensive care unit in KWH. She received HSI vaccination on December 23, 2009 and developed weakness on January 12, and fever, headache and vomiting on January 15, 2010.
