Do flu vaccines carry a potential to cause symptoms of the flu?

If so, how high is the risk? What exactly are they and how long can they last?

The nasal spray vaccine is live and can give you symptoms, but the shot is pieces of the virus and will not make you sick

But the virus is dead or chemically ineffective. The immune reaction can cause a slight fever. If you have actual symptoms of a cold or the flu, then it was brewing before you actually got the vaccine.

Of course, if you get the flu mist that is the actual, active flu virus. That's a different story all together. My first paragraph was about the shot.

yes, there are two basic types of vaccines active and inactive meaning one has active flu stuff in it and one doesn't.

I was prompted by my clinic to visit for it and have been considering it. I'll go soon and ask which ones are available for administration. This was a very helpful answer : )

I went and got my vaccine inactive at a Rexall beside the clinic conveniently 2 days ago. I have experienced no symptoms nor even soreness.

They have changed how the flu vaccine is being made. Now there are less symptoms or none at all.

Same! Especially Flu Season!!! /(^~^)'

Yeah, because the vaccine doesn't cover all strains of the virus. So you get sick from one of the other, less dangerous strains.

Of course. That makes perfect sense. ^

The shot is dead or inactive and does nothig. The nasal mist is alive and active, and can cause temporary symptoms (note it is dangerous for those with respiratory disorders, such as asthma.)

But the vaccine does NOT actually give you the infection. You might get mild symptoms because your immune system does not know the difference between infections and vaccines. It responds as if the vaccine is the threat, and you can feel a few symptoms. That is a good thing. It means it is working.

If you get a full-on infection, it means you were exposed independent of the vaccine, and the vaccine had nothing to do with it. It was a coincidence of timing. I work as a medical lab tech, so I understand this very well.

Also, the vaccine does not cover all strains of the flu, so you may still get the flu. I got the vaccine in early September, and came down with influenza in early November. The flu is influenza by the way, which is a horrible respiratory virus. The stomach "flu" is not related in any way. Not sure who termed it the "stomach flu" but that person has been confusing many people.

Very analytical, efficient, and logical. ^

A vaccine is a "dead" version of the original bacteria or virus. Thus you can get symptoms but they will not be severe and you might not even notice.

Yes, it can cause symptoms,but it is hard to tell how many people get them. The only two large, randomized, controlled double-blind studies I could find shows the only statistically significant effect is for a sore arm:

Wow, you probably went way out of your way for these! Much obliged. I'll follow you for that. BTW, I am not old.
Report as
I got it with no symptoms.
Report as
great! yeah, I was surprised to read about flu-like symptoms on the FDA page, so I looked for the evidence.
Report as
I would not have expected the FDA to cover flu vaccines as they're not exactly medication let alone a drug, which are what fall under their fields.
