What is a vaccine shelf life? In other words, shelf life denotes the length of time for which any item remains fit for use. Why does shelf life matter? DGCI, earlier in February, granted approval to Serum Institute of India (SII), the manufacturer of Covishield, for an extension of the vaccine’s shelf life from six months to nine months. WHO, however, rejected SII’s application for the extension of Covishield’s shelf life, citing the lack of sufficient data, Reuters reported.
