The Chinese mainland reported one more death from A/H1N1 flu Friday after at least 12 people had fallen victim to the disease, authorities said.

The new death case, reported in northern China's Inner Mongolia Autonomous Region, was a 65-year-old woman named Zhao Xiuqin.

She was hospitalized at noon on Monday in Ulanqad city and was tested A/H1N1 positive. She died at around 1:10 p.m. Thursday, after developing complications involving other conditions, including tracheitis, cardio-vascular disease and kidney disfunction.

Twelve deaths from A/H1N1 have been reported from Beijing, Tibet, Qinghai, Xinjiang, Heilongjiang, Guangxi, Hunan, Zhejiang, Hebei, Ningxia and Gansu.

China's Ministry of Health on Thursday stressed that local medical institutions and schools should not charge students for A/H1N1 flu vaccine inoculations.

The government has announced that students, medical staff, public servants and elderly people can receive free A/H1N1 flu vaccines.

The first country to issue a production license for A/H1N1 vaccines, China had inoculated more than 3.78 million people as of Oct. 31, with no reports of serious adverse reaction, according to the Health Ministry.

As of Wednesday, more than 51,490 confirmed A/H1N1 flu cases had been reported on the Chinese mainland, 38,644 of whom had recovered. Among the 153 serious cases, 110 were still in hospital, the ministry said.
