Three ways vaccines prevent the flu

Fighting off the disease

When you receive the influenza vaccination, your body thinks that it has contracted the virus and then builds an immunity to the virus. The vaccination trains your body to recognize the flu, or influenza, and your immune system will get rid it before it causes damage (if you were to come in contact with the flu).

Your shot may not cover all the types of flu, which may be a reason if you contracted influenza after your vaccination.

Yes violent video games can increase the risk of the person wanting to try out the things in reality , in real life . the person may be mad and want revenge and is playing the video game and the video may give more ideas of what to do sounds confusing but yes it does increase the influence sadly on violence out there . there is much evidence of many incidents where violence has happened sadly , like the columbine school shooting on april 20 of 1999 r.i.p to the innocent lives lost may they rest in peace ❤️also violent video games you can choose your choices on who to shoot and what to do and what to do not to get caught like gta 5 no hate on it i'm personally a big fan but you can choose to do bad or good on the game just like real life. people might illusion it in real life n try it out because in the video game it seems so realistic.
