@mangamaker, @dhamil and all -
Flouroquinolone is an antibiotic, not an ingredient in vaccines. No Covid vaccine contains any antibiotic. As far as I know, there are no vaccines for illness that are composed of antibiotics.

Here is a description, directly from the CDC, about the 3 current vaccines and how they work: https://www.cdc.gov/coronavirus/2019-ncov/vaccines/different-vaccines.html

Whether to have a second vaccine dose after a reaction from the first shot depends entirely on the type of reaction you experienced. The vast majority of reaction are an indication of your body's immune response to the vaccine, meaning your system is doing exactly what it should, building resistance to the virus.

Here is the CDC guidance https://www.cdc.gov/coronavirus/2019-ncov/vaccines/expect/after.html about what to expect. It stresses the importance of both doses to achieve protection.

A few are true allergic or life-threatening reactions, which should be carefully reviewed with you primary care provider or an infectious disease doc to determine whether to have a second dose.

Please remember that, as we learn more and more about Covid infections themselves, it is becoming obvious that this virus is NOT "just the flu" - in addition to higher-than influenza risks of severe illness, hospitalization and death, as many as 1/4 of the people who recover from the Covid virus have lingering aftereffects, ranging from annoying to severe. People with underlying conditions (like neuropathy or diabetes) are more likely to suffer severe illness and aftereffects.

I traded a couple months of discomfort (Okay, pain) from inflammatory flares for the chance to get my life back and to keep others safe.

When you are searching for information about the vaccine, the virus, etc it is very important to relay on first-line science and researched based data from the CDC, NIH, Mayo and other major research institutes - if you choose to use Google, please add them to your search, or look for them in your results.
