3-9岁健康孩子需要打几针？？？？ （更新）

[我来说两句]

疫苗计量更新：3-9岁健康孩子暂时只需要打一针,也可能会有再一次更新,注意查看Health Canada网站.



The updated recommendations include three components:

• Children between 6 months of age and under 3 years of age should receive two half-doses of adjuvanted H1N1 flu vaccine, administered at least 21 days apart. Guidance for children in this age group is unchanged.

• Children with chronic health conditions who are between 3 and 9 years of age should receive their first half-dose of the H1N1 flu vaccine as soon as possible. They should also receive a second half-dose of the H1N1 flu vaccine. The interval between the two half-doses should be a minimum of 21 days.
• Healthy children between 3 and 9 years of age should only receive a single half-dose of the H1N1 vaccine, and do not need to return for a second vaccine for now. This recommendation may be updated as more information becomes available.

有别于一周之前，卫生部昨天的最后更新又说是两次了（佐剂型，各半剂量），但又不能完全确定，有待于各地方部门根据情况来斟酌。

有一点没变过：如果打两次，间隔至少21天。

Data are still insufficient to determine whether one or two doses of adjuvanted vaccine will be needed in children under age 10. If two doses are given, the interval between doses should be at least 21 days.

The need for a second dose of adjuvanted vaccine in children under age 10 cannot be definitively determined until additional clinical trial data are available, although preliminary data are promising for young children given one dose of adjuvanted vaccine. It is anticipated that provinces and territories will provide advice on scheduling the second dose in their jurisdiction, taking into account available clinical trial data as well as additional considerations, including vaccine supply.
