And by the way, even in past I have ignored your sarcastic comments but if you can't provide a proper advice better to not reply at all to free queries if that's an issue. I use Practo as I don't like to bother friends and family Doctors for trivial issues. I have taken several paid consultations under my name. Since my phone was getting repaired, I used my son's account. And I asked a proper question to a reply that if it's 6 months you should take TT, when it's wrong if you have taken a primary series you are covered till 5 years atleast for a small cut from a trimmer  that even didn't draw blood. I did ultimately consult a friend who works at Medanta and now am satisfied with his reply. Thank you.
