鉴于病毒与多年前流行的类似，大多数65岁以上者应加以保护。 包括患重感冒的儿童和孕妇在内的低于65岁的人群，也应受到保护。

Most over-65s are protected, because the strain is similar to one that circulated years ago, so it is a younger age group, including children and pregnant women, who are being hardest hit.

孕妇可能有轻微類似感冒症狀，以及出现早产或小产的可能性现象。

Pregnant women may have mild flu-like illness, and infection can lead to premature delivery or stillbirth.
