As CEPI scientists said in April, a total of 115 vaccine candidates are in early stages of development with 78 (79 according to the Milken Institute) confirmed active and 37 others announced, but with little publicly available information (assumed to be in planning or design).
Kama ilivyoripotiwa na wanasayansi wa CEPI mnamo Aprili, jumla ya chanjo 115 zilizoteuliwa zinafanyiwa maendeleo ya hatua za mwanzo, huku 78 zikithibitishwa kama miradi inayoendelea (79, kulingana na Taasisi ya Milken), na zingine 37 zimetangazwa, lakini kwa maelezo chache yanayopatikana kwa umma (zinadhaniwa kuwa zinapangwa au zinaundwa).
