"In September 2010, the California legislature passed a law requiring all students in grades seven through 12 who are in private and public schools to show proof they received the “Tdap” vaccine that protects against pertussis. The shot also protects against tetanus and diphtheria."
Thanks to Fred Pilot for sending me this. I was very sick with pertussis from mid-November through mid-February, and I'm still coughing in the morning. It was the sickest I have ever been in my life. Whooping cough is serious and highly contagious, and it is making a huge comeback thanks to these moron parents who think vaccinations are dangerous.
If you haven't had a pertussis booster within the last ten years, you have no protection. Better get one, because believe me--you do not want to get this. Trust me.
