@merpreb, I'm sorry to hear that you are still experiencing general malaise from the shingles vaccine. See this from the CDC https://www.cdc.gov/vaccines/vpd/shingles/hcp/shingrix/about-vaccine.html):
"About 1 out of 6 people had symptoms severe enough to prevent them from doing regular activities. ... Remember that the pain from shingles can last a lifetime, and these side effects should only last 2 to 3 days."

It's not unheard of to experience general malaise for longer, but you may wish to contact your doctor for peace of mind. All the news these days about vaccines can make one anxious.

With respect to the potential side effects of vaccines for COVID-19 there is much that remains unknown. I think this is a good time to remind everyone that news headlines can be misleading. In the article posted in the first message of this discussion the article states that "doctors say" when the article quotes one doctor.
This article promises questions will be answered.

While some clarification is offered, there are not definitive answers. It's still too early and testing continues.
