I gave my child pentaxim at 1.5 Mths. Now he is 2.5 Months+, but pentaxim is not available in market anymore (out of stock) & the distributor says, it could take 7-15 days for new stock. Please suggest should I hold on for 10-12 days (the child will be 3 Months then), or should I look for alternate (Easy five, pentavac, Tripacel, Boostix, etc). If alternate, then which vaccine is recommended. Also we did not take Hepatitis B, so should we go for it now? Thanks Ronak Sheth
