News Picture: LA County Scenario Suggests COVID 'Herd Immunity' Is Unlikely

FRIDAY, Jan. 21, 2022

Herd immunity in opposition to COVID-19 is unlikely, and dealing with the illness will doubtless hinge on vaccination, therapy and making certain enough hospital capability, a brand new research carried out in Los Angeles County claims.

With herd immunity, most individuals have antibodies from vaccination or prior an infection, so a virus has fewer folks to contaminate and stops spreading,

Early within the pandemic, there have been hopes that herd immunity would finish it, however this new research means that’s unlikely.

“Given that new variants proceed to lead to vital surges — even in a spot like LA County which had a few of the strictest masks mandates and most expansive testing capability within the nation — we have to pivot our pandemic response from minimizing infections to minimizing the hurt from infections, ” mentioned Neeraj Sood, director of the COVID Initiative on the University of Southern California’s Schaeffer Center for Health Policy & Economics.

The researchers estimated that as of April 2021, about 72% of adults in Los Angeles County had antibodies in opposition to COVID-19 by vaccination or a previous an infection.

Despite that top fee of individuals with antibodies, COVID circumstances within the county have practically doubled since final April, in keeping with findings printed Jan. 20 within the journal JAMA Network Open,

Black adults and people from decrease earnings households had far decrease charges of protecting immunity total, regardless of having increased charges of antibodies from previous an infection, the research discovered.

“These communities were hit on both sides: they generally had lower vaccination rates, especially in the first few months that vaccines were available, and they also were harder hit by the earlier waves of COVID,” Sood mentioned.

The pandemic has laid naked extreme well being disparities in Los Angeles, mentioned Howard Hu, chairman of the Department of Population and Public Health Sciences at USC’s Keck School of Medicine. “Going forward we need to redouble our efforts to reduce these disparities.”

The outcomes recommend that policymakers and public well being officers ought to rethink long-term targets in coping with COVID-19 and easy methods to make finest use of sources.

“Testing the symptomatic, ensuring access to new treatments and encouraging vaccinations for high-risk populations should be the pillars of our pandemic response going forward,” Sood mentioned.

“These findings indicate that preventing COVID surges may be increasingly unrealistic, but we can ensure our health care systems and hospitals have the needed capacity and patients have the care they need,” he added.
