How can the school tell if it is a notice issued by the CDC when it sends a notice to fight a voluntary vaccine?

The school sent a notice to take a voluntary vaccine to identify whether it was sent by the CDC. The method is as follows.

1. Check the source of the notice: If the sender of the notice is the official email address or official micro-signal of the school, then it is probably a voluntary vaccination activity organized by the school itself. If the sender is the official mailbox or official micro signal of the CDC, then this may be a voluntary vaccination activity organized by the CDC.

2. Ask the school or CDC: If you are not sure about the source of the notice, you can contact the school or CDC by phone, email or WeChat. And ask them about the specific information and participation methods of voluntary vaccine activities.

3. Pay attention to security risks: If you receive a voluntary vaccination notice from an unidentified person, it is recommended not to click on the link or attachment in the notice easily to avoid fraud or virus attack.
