Hi, My daughter's paed lists Pneumococcal Conjugate vaccine (PCV) as an optional vaccine. What's the purpose of this vaccine? Any one given your babies this? Its pretty costly about 4K, but the cost is secondary to me. What I would really like to know is, is it worth it and why is it an optional vaccine? Also, my daughter got her BCG vaccination 2 days after her birth. It has developed into a nodule now, which the doctor says is normal. But the other day there was some blood oozing from it. I was asked to wipe it with eau de cologne, which I did. The oozing recurred once more. Is this normal. When does the nodule go away? Please clarify. Regards, Poornima.
