    Through antigenic evolution, viruses such as seasonal influenza evade recognition by neutralizing antibodies. This means that a person with antibodies well tuned to an initial infection will not be protected against the same virus years later and that vaccine-mediated protection will decay. To expand our understanding of which endemic human viruses evolve in this fashion, we assess adaptive evolution across the genome of 28 endemic viruses spanning a wide range of viral families and transmission modes. Surface proteins consistently show the highest rates of adaptation, and ten viruses in this panel are estimated to undergo antigenic evolution to selectively fix mutations that enable the escape of prior immunity. Thus, antibody evasion is not an uncommon evolutionary strategy among human viruses, and monitoring this evolution will inform future vaccine efforts. Additionally, by comparing overall amino acid substitution rates, we show that SARS-CoV-2 is accumulating protein-coding changes at substantially faster rates than endemic viruses. Display omitted •Ongoing adaptive evolution in human endemic viruses is largely in surface proteins•Immune evasion drives continuous adaptive evolution in many endemic human viruses•Antigenic evolution occurs in several viral families•SARS-CoV-2 is accumulating protein-coding changes faster than other endemic viruses Kistler and Bedford examine the genomes of 28 human endemic viruses and estimate that 10 of these viruses are undergoing antigenic evolution. This demonstrates that evasion of antibody detection is not an uncommon evolutionary strategy among the viruses that commonly infect humans.
