Flu vaccine only has ~40% efficiency. The important part is to reduce the severe cases. When you get cold, it's not severe and you can get well in few days or weeks. You don't need to get to the hospital. Therefore the hospital can take care of other patient.

Even if the vaccine doesn't have too much efficiency, at least it reduces the severe cases. People can stay at home and they will get well on their own in few days.


The point of vaccine is actually to "replicate" the actual virus so your body can use that as "punching bag". But since some vaccine give live attenuated virus, it won't replicate the bad part of the virus in your body. So your body can take time as they want to fight the virus. Then your body will know which part of the virus to attack when the actual virus come into your body. So yes, your body will see it as a threat and fight the vaccine.

From what I understand with the Pfizer and Moderna vaccines, they do not contain the live virus. I believe they contain the spike protein which allows for our bodies to create antibodies against COVID, which who knows for how long we will retain the antibodies from this vaccine.
