I believe part of the scientific argument against the bcg jab is that it is only 80% effective but anyone who has had it would subsequently always test positive in a blood test for TB exposure? I had the bcg jab and so did piggy daddy, its the one vaccination his parents consented to as they lived on a farm with rescue badgers (though whether it would protect against bovine TB is open to debate...) but my daughter's generation (millenials!) didnt get bcg in the UK and I dont think the USA offer it at all, though they do routinely vaccinate against chickenpox there...
