(Portland, OR) -- A new study out of Oregon shows people who are vaccinated against COVID-19 and then get a breakthrough infection end up with super-immunity. A study of patients by Oregon Health Science University finds that vaccinated people who get COVID-19 have antibodies that are one-thousand percent more effective than antibodies that come from a second dose of the Pfizer vaccine. The study shows it's especially effective against the Delta variant, but they believe it would have the same effect against all variants.
