Schneller aber nicht schlimmer (Corona)

Some variants become more common in a population simply by luck, not because the changes somehow supercharge the virus.

In short: It will be very hard for the coronavirus to escape the body’s defenses, despite the many variations it may adopt.

Escape from immunity requires that a virus accumulate a series of mutations, each allowing the pathogen to erode the effectiveness of the body’s defenses. Some viruses, like influenza, amass those changes relatively quickly. But others, like the measles virus, collect hardly any of the alterations.

Even the influenza virus needs five to seven years to collect enough mutations to escape immune recognition entirely, Dr. Bloom noted. His lab on Friday published a new report showing that common cold coronaviruses also evolve to escape immune detection — but over many years.
