Three new articles published in the New England Journal of Medicine provided powerful evidence of reduced risk of COVID-19 in healthcare workers who received one or more vaccinations against the disease. Health care workers have a much higher exposure to COVID-19 than the average person, so this kind of data is extremely interesting.
I have written in the past about challenge studies, where the subjects are intentionally exposed to SARS-CoV-2 after receiving the vaccines. Many people, including myself, think they are unethical. However, healthcare workers, who are unintentionally exposed to the virus, function as a “challenge study” in that those who are vaccinated do not have to “wait” for an infection, it’s going to happen eventually.
It is also important to note that these healthcare workers are more frequently tested for the virus than the average person on the street. This alone makes the data even more intriguing.
These three articles describe the level of reduced COVID-19 risk after being vaccinated in a healthcare setting. The results should convince anyone that the vaccine is very effective.Continue reading “Reduced COVID-19 risk in healthcare workers after vaccines – real-world evidence”
