Hi and welcome. So sorry you're finding yourself here.
You are not alone in wondering if there is a connection. The vaccine you received was for Hep. B, and there's been a lot of research and debate over whether or not this particular vaccine is involved with MS.http://www.cdc.gov/vaccinesafety/Vaccin ... hep_b.html
There are lots of environmental triggers known to be involved in MS progression or worsening of symptoms. Some of the ones we know about, that have peer-reviewed science behind them, are EBV, vitamin D levels, obesity, lack of sleep, salt intake, processed foods, and latitude.
Vaccinations raise levels of inflammation in the body, and also limit vasodilation, so blood flow becomes hampered. http://www.ncbi.nlm.nih.gov/pubmed/22866006
All of the environmental factors I mentioned above do the same--by creating endothelial dysfunction.
Here's a study where they gave participants a typhoid vaccine and watched what happened. There was a pro-inflammatory cytokine response, increased oxidative stress and the blood vessels constricted, due to interference in nitric oxide. This was enough for the researchers to say it created a temporary high cardiovascular risk.http://cardiovascres.oxfordjournals.org ... 2.full.pdf
I put together some research to help my husband feel like himself again. Seven years past his MS dx, he's had no progression and is doing really well. Maybe some of the ideas might help you. http://ccsvi.org/index.php/helping-myse ... ial-health
