Original title: who's second response "problem vaccine": no additional side effects
Beijing News Alerts (reporter Li Dandan) following three ministries in China today "problem vaccines" held a press conference after the meeting, the World Health Organization late in the day in response to the event for the second time. Who reiterates that outdated or improperly stored vaccines should be vaccinated do not generate any additional side effects and toxicity risk.
Vaccines in the event of doubt, China World Health Organization carried out one by one to respond.
1. What is the difference between first class and second class of vaccines in China?
A vaccine is that the Government use of the expanded programme on immunization vaccine, children against 12 infectious diseases. A vaccine is provided free of charge to children in China, children must be vaccinated with the vaccine. Is II vaccine parents choose the supplementary immunization vaccines for children, such as caused by preventable Haemophilus influenzae type b disease, invasive pneumococcal disease and rotavirus gastroenteritis. Vaccination against class II needs at their own expense.
2. How to ensure vaccine quality issues?
Who vaccine to China (includes vaccines and vaccine) have confidence in the production and licensing. Management of vaccines in China National regulatory authorities (State food and drug administration and the National Committee on health and family planning) has 2010 and 2014 through the who assessment, meeting all international standards, including the ability to ensure use of current good manufacturing practice (GMP). The events associated with vaccine storage and distribution of vaccines. A vaccine distributed by the Government's centers for disease control systems from manufacturers to the point of inoculation, controlled temperature cold-chain system have been through the who and United Nations Children's Fund to assess and confirm the high quality of the cold chain system. But two types of vaccine distribution through the system.
3. "Toxic response", does it mean harmless?
"Drug reaction" means children expired or improperly stored vaccines became sick after the possibility is extremely low. However, if the vaccine due to expiration or improper treatment ineffective, lack of vaccines for disease prevention in children, may in future infections and damage. Similar to the consequences of this situation have not been vaccinated.
4. If the children have been vaccinated against noncompliance, to replant it?
Normally, expired or improper handling of the vaccine after inoculation, the body may not develop immunity to vaccines against the disease and should therefore be vaccinated again. Vaccination is safe again, immediately inactivated vaccines can also be vaccinated with live attenuated vaccine in 28 days. But because of the various vaccine-preventable diseases in different ages have different risk, so not all the vaccine necessary vaccinations. Such as measles, rubella, hepatitis a, hepatitis b and chicken pox and other diseases, can be a blood test to know children's immune and confirm that you need to be vaccinated again. If considered to be vaccinated, you should consult your professional vaccination points.
5. Security risk is very low, how low?
As far as we know, is not within the specified temperature range storage of vaccines or expired vaccine was not contaminated by toxic vaccines or vaccines. The problem, however, is not sure whether the vaccine is still effective. All vaccination has some risks of side effects, such as allergic to the ingredient in a vaccine reaction. But outdated or improperly stored vaccines should not cause any additional side effects and toxicity risk.
6. If the children have been vaccinated against noncompliance, what consequences will it have?
After improper storage of vaccine is in in children, sick is very unlikely due to the vaccination. However, if vaccine due to expiration or improper treatment ineffective, lack of vaccines for disease prevention ability of the children, may in future infections and damage. Similar to the consequences of this situation have not been vaccinated.
7. Should you give children vaccinated?
Yeah. Chinese children, like other children around the world, need Vaccine protection, avoid infection vaccine-preventable diseases. China's immunization program can protect children from 12 kinds of infectious diseases. Except for a few outside children cannot be vaccinated for medical reasons, all children should be vaccinated according to the routine immunization schedule. Vaccination is the protection of children the safest way to avoid infection vaccine-preventable diseases.

世卫再回应问题疫苗：过期不会产生额外副作用|疫苗|世卫组织|过期疫苗_新闻资讯
原标题：世卫组织二度回应“问题疫苗”：不会产生额外副作用
新京报快讯（记者李丹丹）继中国三个部委在今日下午就“问题疫苗”召开记者会后，世界卫生组织在当天晚间第二次回应该事件。世卫组织重申，接种过期或不当储存的疫苗应不会产生任何额外的副作用和毒性反应风险。
世界卫生组织对中国疫苗事件中的疑问进行了一一回应。
1。中国的一类和二类疫苗有何区别？
一类疫苗是政府扩大免疫规划使用的疫苗，使儿童能预防12种传染病。一类疫苗免费向中国儿童提供，也是儿童必须接种的疫苗。二类疫苗是父母自主选择为儿童补充接种的疫苗，例如可预防B型流感嗜血杆菌所致疾病、侵袭性肺炎链球菌病和轮状病毒胃肠炎。接种二类疫苗需自费。
2。疫苗质量问题如何保证？
世卫组织对中国疫苗（包括一类疫苗和二类疫苗）的生产和许可有信心。中国管理疫苗的国家监管部门（国家食品药品监督管理总局和国家卫生和计划生育委员会）已于2010年和2014年通过世卫组织的评估，符合所有国际监管标准，包括能确保使用现行的药品生产质量管理规范（GMP）。此次疫苗事件主要与疫苗的储存和分发有关。一类疫苗由政府的疾控中心系统从生产商分发到接种点，其可控温度的冷链系统已通过世卫组织和联合国儿童基金会评估并确认为高质量的冷链系统。但二类疫苗不通过该系统配送。
3。“无毒性反应”是否代表无害？
“无毒性反应”指儿童接种过期或储存不当的疫苗后生病的可能性极低。但是，如果疫苗由于过期或不当处理失去效力，儿童将缺乏疫苗针对疾病的预防能力，可能在未来感染疾病，对其造成伤害。这种情况跟未接种疫苗的后果类似。
4。若孩子接种了无效疫苗，要补种吗？
一般情况下，接种过期或不当处理的疫苗后，人体对疫苗针对的疾病可能不产生免疫能力，因此应重新接种疫苗。重新接种疫苗是安全的，可立即接种灭活疫苗，也可在28天后接种减毒活疫苗。但由于不同疫苗可预防疾病在不同年龄阶段所产生的风险不同，所以不是所有疫苗都有必要重新接种。诸如麻疹、风疹、甲肝、乙肝和水痘等疾病，可通过血液检测了解儿童的免疫情况和确认是否需要重新接种疫苗。若考虑重新接种疫苗，应咨询预防接种点的专业人员。
5。安全风险非常低，到底有多低？
据我们所知，未在规定温度范围内储存的疫苗或过期疫苗不是被污染的疫苗或有毒性的疫苗。然而，问题在于不确定疫苗是否仍有效力。所有疫苗的接种均有一定的产生副作用的风险，例如对某疫苗成分出现过敏反应。但接种过期或不当储存的疫苗应不会产生任何额外的副作用和毒性反应风险。
6。若孩子接种了无效疫苗，有何后果？
儿童在接种不当储存疫苗后，由于接种疫苗而生病的可能性极低。但是，若疫苗由于过期或不当处理失去效力，该儿童将缺乏疫苗针对疾病的预防能力，可能在未来感染疾病，对其造成伤害。这种情况跟未接种疫苗的后果类似。
7。应该给孩子注射疫苗吗？
是。中国儿童与全球其他儿童一样，需要疫苗的保护，避免感染疫苗可预防疾病。中国免疫规划可保护儿童免于患12种传染性疾病。除极少数儿童因医学原因无法接种疫苗之外，所有儿童都应根据常规免疫程序接种疫苗。接种疫苗是保护儿童避免感染疫苗可预防疾病的最安全途径。
