Good manufacturing and regulatory practices are designed to prevent problems in the process of ensuring quality vaccines. But when problems are found, the regulator must take action. WHO commends the quick and transparent actions taken by China NDA to suspend production at the company and investigate these incidents.
WHO assessed the national regulatory authorities in 2010 and 2014, and found that they met WHO criteria as a functional regulator for vaccines with a clear commitment to continual improvement. WHO welcomes the fact that China's NDA continues to work with WHO's Regulatory Systems Strengthening program, as it has been doing for nearly 20 years. While the current incident is clearly regrettable, the detection of this event by an unannounced inspection shows that the regulatory authority’s system of checks and balances to protect population health is working.
WHO reiterates that quality-assured vaccines are critical for disease prevention and urges countries to continue using this cost-effective public health intervention. The Expanded Program on Immunization in China has brought results. It has made China free from polio and significantly reduced vaccine-preventable diseases such as measles, mumps, rubella, and hepatitis A and B among children. To that end, WHO is also supporting vaccine manufacturers in China to ensure that they comply with international standards and meet WHO Prequalification expectations.
怎么知道孩子打的疫苗是否是有问题的
疫苗都是有疫苗批号的，所以可以通过追溯疫苗批号，来看自己孩子接种疫苗的生产日期以及有效期。并且孩子的接种手册上有接种时间，通过推算可以得出孩子接种的疫苗是否在有效期内，所以说宝宝接种的疫苗是否过期，是完全可以溯源的。 5/7 首页 上一页 3 4 5 6 7 下一页 尾页 |
