Interpretation

Introduction of conjugate vaccines against S pneumoniae and

H influenzae into the childhood immunisation schedules of

African countries could substantially affect survival of children

with sickle-cell anaemia

optional after 5 years

o 125 mg twice daily (< 3 yr old);

o 250 mg twice daily (> 3 yr old).

o Erythromycin ethyl succinate (EES) 10

mg/kg/dose, twice daily for those allergic to

penicillin

Conclusions


1. Newborn screening for SCD makes sense in Africa.

2. Implementation of a Public Health Newborn Screening

Programme is feasible in Ghana in both rural and urban

settings.

3. Ghanaian healthcare systems and staff can support all

phases of comprehensive management of SCD.

4. Children with SCD born in Ghana, diagnosed at birth and

given comprehensive healthcare, have reduced mortality.


1. US funding for pilot project ended March 2008

2. Screening has continued with support from MOH,

GHS, Children‟s Hospital of Philadelphia, and Sickle

Cell Foundation of Ghana (SCFG)

3. SCFG proposal for national scale-up submitted to

Ministry of Health 2006 and 2007

4. 2007-2010: Planning meetings among MOH, Ghana

Health Service, SCFG, National Health Insurance

Authority

5. SCFG secures support from Brazil Government

Progress Report (1/2)



6. Brazil-Ghana Technical Cooperation Agreement in

SCD signed (Sep 2009)

7. National Programme of Newborn Screening for SCD

launched Nov 2010

• Technical Advisory Committee inaugurated

• Screening Plan submitted to MOH, Nov 2011

• Steering Committee being established

8. National scale-up in ALL other Regions, 2012

9. Initial Regional Training Workshops completed Nov,

2011.
