Understanding Herd Immunity

[Dr. Oz and Dr. Roizen, MDs] Understanding Herd Immunity By Dr. Oz and Dr. Roizen, MDs Chances are you've heard of herd immunity, but like most folks you don't know how it really works. Fortunately, the experts at the U.S. Government Accounting Office's Science Technology Assessments and Analytics team and the medical journal JAMA have recognized how important it is to look at what we know and don't know about it and get the facts out to you. “A population can establish herd immunity to an infectious disease once a large enough portion of the population — typically 70% to 90% — develops immunity. Reaching this threshold limits the likelihood that a non-immune person will be infected. This process slows or stops the spread of the disease,” they wrote. Special: [Randy Jackson: ‘This Drink Is Like a Powerwash for Your Gut’]( For polio, 80% to 86% of the population must be immune for the spread to slow or stop. For measles, the threshold is very high: 91% to 94%. For COVID-19? It's unknown. That is because we do not yet know: • How many folks it takes to achieve herd immunity from infection or vaccination • The number of secondary cases typically generated by an infected individual • The viral mutation rate (because the virus can change enough to escape the effect of antibodies that squelch a previous version of the infection) • The length of time immunity lasts Measles and polio immunity typically last a lifetime; immunity to influenza, just a year or so. For COVID-19, it may vary depending on the intensity of the individual infection. Don't bank on naturally occurring herd immunity. The price paid in human suffering and medical costs may be too high. Until an effective vaccine is available to everyone, it is each person's responsibility to limit community spread by wearing a mask, washing hands frequently, maintaining social distancing, and limiting gatherings. Let's get back to work, but do it wisely and safely. --------------------------------------------------------------- Special Message --------------------------------------------------------------- [Don't Buy Another Bottle Of Olive Oil Before Seeing This]( If you cook with or consume olive oil, it is very important that you read this carefully.
