In today’s MMWR, a study of COVID-19 infections in Kentucky in people previously infected with SAR-CoV-2 shows unvaccinated individuals more than twice as likely to be re-infected by COVID-19 than those who were fully vaccinated after onset contract the virus. These data further indicate that COVID-19 vaccines offer better protection than natural immunity alone and that vaccines, even after a previous infection, help prevent re-infections.

If you have had COVID-19 in the past, please get vaccinated anyway. This study shows that you are twice as likely to get infected again if you are not vaccinated. Getting vaccinated is the best way to protect yourself and others, especially since the most contagious Delta variant is spreading across the country. “

Dr Rochelle Walensky, Director of the CDC

The study of hundreds of Kentucky residents who had already been infected until June 2021 found that those who were not vaccinated had a 2.34 times greater risk of re-infection than those who were fully vaccinated. The results suggest that among people who have had COVID-19 in the past, full vaccination offers additional protection against reinfection.

What’s more, a second publication from the MMWR shows that vaccines have prevented COVID-19-related hospitalizations among the age groups most at risk. As cases, hospitalizations and deaths increase, data from today’s MMWR reinforces that COVID-19 vaccines are the best way to prevent COVID-19.

COVID-19 vaccines remain safe and effective. They prevent serious illness, hospitalization and death. Additionally, even among the rare cases of COVID-19 among fully or partially vaccinated vaccines, people are more likely to have a milder and shorter illness than those who are not vaccinated. The CDC continues to recommend that all ages 12 and over be vaccinated against COVID-19.
