Vaccines targeting Covid-19 are able to curb deaths and hospitalization in patients substantially, including those infected by the highly-transmissible delta variant that drove India's devastating second wave and is now triggering curbs from Los Angeles to Melbourne.
About 0.4% died among those who got infected after inoculation -- called breakthrough infections -- while nearly 10% needed hospitalization, according to a new study by researchers led by Indian Council of Medical Research's Nivedita Gupta. The study, which analyzed genome sequencing data of 677 Covid patients, found 86% of the fully-vaccinated cases were due to the delta variant.
