Trying to keep all the vaccine info in one place so feel free to add what is accurate and helpful. Thanks!

Pneumococcal vaccine: PCV= pneumococcal conjugated vaccine PPV-pneumococcal polysaccharide vaccine

Healthy normal kid: PCV at 2,4,6,12

Sickle cell kid: PCV at 2,4,6,12 with Pn and then once they turn 2 give them the PCV because of their high risk of asplenia.


From peterskype:

Children younger than age 2 y o have poor immuno response to MPCV which is a conjugate vaccine. May be it's the reason why these two ( MPCV and PPCV ) are given after 2 years


From usmle8484
