Identifying SARS-CoV-2 epitopes targeted by current vaccination could help improve future vaccines
Researchers in the United States have identified antibody-inducing epitopes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in individuals vaccinated against coronavirus disease 2019 (COVID-19) that could be used for future diagnostics, therapeutics, and vaccine design.
Using an approach called reverse vaccinology, the team identified distinct amino acid motifs and epitopes of the SARS-CoV-2 spike protein that elicit specific immunoglobulin IgG antibody responses that have previously been associated with neutralization of the virus.
The spike protein is the main structure SARS-CoV-2 uses to infect cells and the primary target of neutralizing antibodies following vaccination or natural infection.

Why do humans sleep? Most people spend one-third of their lives asleep. For most of human history, individuals have been much more vulnerable to enemies and predators when sleeping.

Some Benefits of Sleep
One reason for sleeping may be to rest the brain and body. Nevertheless, most organs continue to work during sleep. In particular, the brain is highly active during sleep.
