I got my flu shot about two weeks ago. My doctor mentioned the shingles vaccine, but said now is not a good time for that one because it causes a slight fever which could cause one to be quarantined if a temperature monitor detects a high reading.
The shingles vaccine (first dose) put me in bed for a week last year with flu like symptoms. So schedule that time just in case before you get it.
The second dose was very small side effect.
