Nope. I'm a big believer in vaccines, but honestly staying inside is probably a better protection than any vaccine. The chance that my 12 year old is going to get Tetanus, or Diptheria because his vaccine is a few months late is impossibly small, and the isolation is keeping him out the settings and activities where HPV, Pertussis, or Meningitis would be a risk. So, vaccinating him even 6 months late isn't going to be a concern.
