I'll tell you why I don't trust 'em - My son now has whooping cough. Will the Doctor tell me it's whooping cough? No. Because it mucks up all their wonderful records and statistics concerning their vaccinations. He's been coughing and spewing for 5 weeks now. I know it's a virus and it'll run it's course, but poor kid. Actually he's gotten so used to carrying a bowl around with him; he dare not go out without it. He makes very light of it. Some of his friends (and believe me there are many of them) have had this virus for 7-8 weeks. There won't be many going back to school when half term is over.
