2 Can people get flu from the flu vaccine
The answer is no, because the flue vaccine contains killed virus.

人不会因为注射了流感疫苗而得到流感,因为流感疫苗里的病毒都是被杀死了的。 不过一些人在注射了疫苗以后会有些轻微的症状,还有可能有过敏的症状.
The "flu shot"—an inactivated vaccine (containing killed virus) that is given with a needle, usually in the arm. The flu shot is approved for use in people older than 6 months, including healthy people and people with chronic medical conditions.
