As part of a brand new study, Yale looked at all the available data about natural immunity and was able to estimate how many people without vaccines can get infected with COVID-19.🤦♂️
The researchers were not worried about catching a disease from being with people, but only that they would get the disease back.
You might have heard about natural immunity people develop when they catch COVID-19 and then heal from it. But how is it possible that you could get infected a second or even a third time?

Natural immunity is not forever. It turns out that it lasts a short time, and you may be surprised by how little time it really lasts. If someone is not vaccinated, they will get the illness again in 16-17 months.🤷♀️
The authors of the study say that they wanted to find out if people could get SARS-CoV-2 again after being infected. They were trying to answer a question that was hard to answer. People have been getting infected, but they don’t know how long it takes for them to be immune from SARS-CoV-2 again.
Do you expect immunity before becoming vulnerable again?
The researchers found that the body’s natural immune system is quite limited.
Hassler said, “Our results are based on the average of how long immunity lasts across multiple infected people. But any one person might have a different time of immunity because it depends on their immune system, age, and other things.”
This new data is concerning because, as the Centers for Disease Control and Prevention updates show, only 57.1% of Americans have been vaccinated against COVID-19.
