About 1%, or practically 34,000, developed breakthrough infections.

Vaccination decreased the possibilities for any Lengthy COVID signs by a “modest” 15%,” though it minimize the chance in half for lingering respiratory or clotting issues, stated Al-Aly, a researcher with Washington College and the Veterans Affairs well being system in St. Louis. These signs included persistent shortness of breath or cough and blood clots in lungs or veins within the legs.
Infectious illness professional Dr. Kristin Englund, who runs a middle for Lengthy COVID sufferers on the Cleveland Clinic, stated the Nature Drugs research mirrors what she sees at her clinic. Lengthy COVID sufferers there embrace individuals who have been vaccinated and acquired boosters.
“As we’ve no clear remedies for Lengthy COVID, it’s important for everybody to get vaccinated and use different confirmed strategies of prevention corresponding to masking and social distancing with a purpose to forestall infections with COVID and thus Lengthy COVID,’’ Englund stated.

Older adults’ dangers have been increased for sure circumstances, together with strokes, mind fog, kidney failure, and psychological well being issues. The findings are worrisome as a result of these circumstances can hasten older adults’ wants for long-term care, the report authors stated.
