Reply to comment by AutoModerator in New evidence suggests that ‘hybrid’ immunity, the result of both vaccination and a bout of COVID-19, can provide partial protection against reinfection for at least eight months. Immunity acquired by booster vaccination alone seems to fade somewhat faster. by MistWeaver80

I wonder about regional varients though. I had COVID in July in the Middle East, after being vaccinated there, and then got it again in North America less than 5 months later. For people who travel internationally often, are we more susceptible to getting region variants? Maybe I can collect them all!

Main point.

>When time is expressed in units of orbital or thermal timescale in thin-disk models, we find a universal structure function, independent of luminosity and wavelength, supporting the model of magneto-rotational instabilities as a main cause.

>Scientists study the patterns of spinning things in space like planets around stars. They found out that these spinning things sometimes flicker, which means they change brightness quickly. This happens because of something called "magneto-rotational instabilities." It's like when two magnets push and pull each other and make patterns. The spinning things in space also do this and it causes them to flicker. No matter how bright or what color the spinning thing is, the flicker patterns always look the same.

Close enough

The virus won't mutate in a vaccinated person? Plenty of vaccinated people are getting sick with COVID, some seriously.

Much better to get vaccinated and then get COVID by licking doorknobs and risk death or crippling medical problems than to just get vaccinated more often I guess?
