Pediatrics/Prevnar n pentaxim


Hello doctor,it's dimple again my two worries are: gave pentaxim n prevnar together to my 3.5months daughter
2.the gap between the 2nd booster of prevnar 13 was only 27 days which was less than 4weeks as generally recommend
Pls advice was vaccination done in order

Hi Dimple,

Prevenar 13 and Pentaxim are normally given together only.

Gap between 2 doses of the same vaccine should at least be 28 days. Since the vaccines have already been given, nothing needs to be done. The effect of vaccines would be marginally less.

I would also like to inform you that Pentaxim (and any other brand with DTaP: "Gentle"/ "Painess" DTP) are not recommended in In India now. It has been found that these are less effective than brands that contain DTwP ("Normal" DTP). Hence we are not using DTaP since Oct 2013. WHO also is not recommending DTaP now. Please confirm local recommendations from your doctor.

Best wishes,
