Since you’ve had shingles, you know how it starts and what the rash looks like.
If you get to the dr/urgent care within 2-3n days of starting symptoms, you can get medicine to halt the viral replication and have a milder case of it.
Mr mm isn’t going to get the vaccine either, but we do know what to look for this time and will not wait.
Good idea to keep the Rx antivirals on hand.
