A latest research printed in bioRxiv by Indian SARS-CoV-2 Genomic consortia in addition to scientists on the College of Cambridge within the UK have reported that the immune escape of each mutations, E484Q and L452R, is lower than that of variants with E484K. The research mentioned that the Indian mutation contributed to the epidemic wave in India and that development to critical sickness and demise was low in all research.
