My son had the Pfizer vax (he is 12) last week. He is having a flare with his OCD, but otherwise ok. We are managing it with our pediatrician. I would rather he get this flare than what would be a MUCH worse flare with COVID. Having spoken with the pediatrician and UCSF pediatric neurology, that seems to be the consensus. His second shot is in 2 weeks, so will see how he fares after that one. Either way, just happy that the flare is not horrendous and I presume, it will be temporary.
