Reduced COVID-19 risk in healthcare workers after vaccines – real-world evidence

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.

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.
