This comes as some countries decided to give different second doses in the wake of vaccine shortages and supply chain challenges, especially for AstraZeneca. "Data from mix and match studies of different vaccines are awaited - immunogenicity and safety both need to be evaluated." But the Health ministry is yet to decide whether mixing vaccines from different manufacturers will be the next viable option. The government expects 1.7 million doses of Pfizer vaccine from the US government from the 14 million the US has pledged to donate to the African states. Another 1,037,353 have received their first dose with the uptake of the second dose among those who received their first dose being at 56 per cent.
