Sure it will...... I personally have had only one flu vaccine shot and that was 20 years ago. I did not enjoy the experience so that was the last one. I rarely get the flu and when I do it is usually not nearly as bad as what other people suffer.
I recently found out at 23andme that I have a set of genes associated with higher resistance the flu so I really do not need the vaccine - thank you very much.
Stop living in fear.
We also. We considered it one and done many years ago. The VA keeps asking me if I would like one and they get denied.
