Companies who want to manufacture COVID-19 vaccines and governments interested to make this happen must ensure that raw materials are available, adequate infrastructure and equipment are available, that high levels of quality control are maintained and that a large enough and skilled workforce is available, a report in the British Medical Journal said on May 10, 2021.
However, drawing it all together, "the patent is still the critical barrier", said Davinder Gill, an expert on vaccines and former vice president for global biotherapeutics at Pfizer. "If you compare India with other countries in the sub-continent, and if the same waiver was provided to all countries, India would be the one to perform well. In India there is the capacity, and experience, to make drugs and vaccines." Without technology transfer, it may take longer, but Indian companies will be able to develop the vaccines, he said, adding, "But the patent is still the critical barrier which poses the risk and is preventing companies from jumping in."
