When people are infected with the Delta variant, they carry approximately 1,000 times more virus compared with previous versions of the virus, according to a recent study. All that virus can overwhelm even the strong protection from the vaccines.
As good as they are, these shots aren't perfect. Their protection differs from person to person depending on age and underlying health. People with immune function that's weakened because of age or a health condition can still become seriously ill, and, in very rare cases, die after vaccination.
After two doses, vaccines prevent symptomatic infection about 79% of the time against Delta, according tocompiled by Public Health England. They are still highly effective at preventing hospitalization, 96% after two doses. "We know the vaccine reduces the likelihood of carrying the virus and the amount of virus you would carry," Wen told CNN.
If you're older or immunocompromised, Schaffner recommends what he calls the"belt-and-suspenders approach," in other words, do everything you can to stay safe.Thankfully, because they are vaccinated, they just feel under the weather like a mild flu.Not having severe illness means it IS working. Get the shot.
