Fitch warns SAâs slow rate of vaccine roll-out poses risk to economy By Siphelele Dludla Share JOHANNESBURG - FITCH Ratings Agency on Friday warned that the Covid-19 pandemic would continue to pose risks for South Africaâs economy well into 2022 as vaccine roll-out was proceeding slowly. Fitch said South Africaâs medium-term growth would remain low at less than 2 percent, a key rating constraint, complicating fiscal consolidation as reforms remained limited in scale and slow in implementation. It said this will also limit the government's ability to contain the debt-to-GDP ratio. âThe government has secured enough doses to inoculate the adult population, but most will arrive only in the second half of 2021,â Fitch said.
