The world's larges vaccine supplier Serum Institute of India syas it will not be able to meet its target production of 2 billion doses for 2021. It says vaccines will not be available for export from the Institute till the end of the year. The Indian government has initiated an effort to diversify its vaccine production by distributing it among many suppliers in India's large pharmaceutical industry so that constraints at any one supplier would not affect the overall supply for use inside India and the production that can be sent overseas.
Another setback was seen in the US as 100 million doses of J&J one dose vaccine at a Baltimore plant are being checked for contamination.
