Vaccines should keep people healthy and away from the fear of diseases. However, some problematic vaccines found in China have caused big worries and anger among people recently.

    Since 2011, 12 types of vaccines, such as vaccines for rabies and the flu, have been sold illegally in 24 provincial-level areas. Together they are worth more than 570 million yuan and were sold by a mother and daughter crime(犯罪)team.

    The mother, surnamed Pang, once worked at a hospital in Shandong. After leaving the hospital, Pang began to sell vaccines without a licence. Qualified companies made the vaccines, but Pang did not keep them at a low temperature. As a result, the vaccines could lose their effect.

    Pang and some other criminals have already been arrested. Local governments are still tracing(追踪)the problematic vaccines in different areas.

    Although the governments are working on the case, it has caused worries in the public. Some parents worry that the problematic vaccines could be toxic(有毒的)and refuse to take their children to get vaccinated in hospitals.

    But according to the World Health Organization, there is little risk of these vaccines, and they are seldom toxic. The WHO still encourages parents to protect their children's health through vaccination.

    Nowadays, more and more people are in poor health. If we want to keep (health), we should have a healthy eating .

    First, we should have a (balance)diet. It (mean)we should have (difference)kinds of healthy food. So we should eat not only meat vegetables and fruit. Second, we had better (eat)regular meals. We need to eat breakfast, lunch dinner every day, because regular meals throughout the day can give (we)enough energy to carry out our daily activities. Third, we should get from fast food.
