Bhubaneswar, Oct. 29 -- New York: In a major study, researchers have discovered a technique that could help increase the effectiveness of vaccines against the novel coronavirus, the virus that causes Covid-19.

Since it began spreading in early 2020, biomedical researchers have been in active pursuit of an effective vaccine.

According to the study, published in the journal Advanced Materials, one answer might lie in designing vaccines that partially mimic the structure of the virus.

"One of the proteins on the virus - located on the characteristic Covid spike - has a component called the receptor-binding domain, or RBD, which is its Achilles heel," said study author Jonathan F Lovell from the University at Buffalo in the US.

That is, h...
