hello, I m Swarnava from India. In January, 2014 I took post-exposure rabies vaccination 5 (dose 0,3,7,14,28). But mistakenly it was given on 0,2,6,13,27. Now i need to take post exposure rabies vaccine again and the doctor told me that the first two dose (0,3) will be enough as i m already immune. So am i perfectly immune or should i have to take the whole five of it (0,3,7,14,28)?
