I’d postpone the booster for at least a few months. I could get my second booster but have put any plans on hold indefinitely. Also keeping my kids at single Phizer shot. A lot of data is pointing towards more risk (rare) for second shot in children (particularly males) than the threat Omicron presents.
Recently read a story out of the UK where many health professionals are suggesting suspending vaccines to children ages 12-18. Will see if I can find it.
