The recent death of a woman in Taipei County who died after being immunized against the influenza (H1N1) virus was caused by coronary heart disease, and therefore unrelated to her getting the vaccine, the Banciao District Prosecutors' Office said Wednesday. The 78-year-old woman had been given an H1N1 immunization shot on Dec. 22, 2009 and died on Dec. 25. The Banciao District Prosecutors Office and the Institute of Forensic Medicine under the Ministry of Justice conducted an autopsy on Dec. 30. According to the autopsy report, which was released Tuesday night, the woman's cause of death was coronary heart disease, so she died 'a natural death', said chief prosecutor Cheng Hsing-hung. The autopsy report shows that no fatal analphylatic shock (a severe allergic reaction), infections or other complications have been found in the case, and the woman's relatives have no objections to the autopsy report, Cheng added. Cheng said the public should not be misled by incorrect media reports, panic and avoid receiving the vaccine. Meanwhile, another autopsy report of a 45-year-old man, who died two days after receiving the vaccine last month, failed to help officials determine whether the man's death was related to the vaccine. According to Pingtung District Prosecutors Office, the man's cause of death was choking on food, which might have resulted from antipsychotic or pain relief medication the man had taken, but the possibilities of post-vaccination nausea or vomiting could not be ruled out. The autopsy report said there was no proof of any fatal analphylatic shock, infections or other complications in the case. Since Taiwan began its vaccination program against the H1N1 virus last year, there have been 17 reported cases of people who died after getting the vaccinations. So far, health authorities have not confirmed that any of the cases are caused by side effects from the vaccine. Among the 17 deaths, no common clinical symptoms were found. Three cases have been proven to be unrelated to the vaccine, while the remaining 14 cases are still awaiting further investigation, the report said. The 17 deaths are among 168 cases of 'suspected serious adverse events' following H1N1 vaccinations, according to a weekly monitoring report released by the Central Epidemic Command Center Tuesday.
