In a recent study conducted by the CDC, it has been confirmed that both the Pfizer and Moderna COVID-19 vaccines are remarkably effective at preventing infections in real-life scenarios. The study, which involved healthcare workers and first responders, revealed a staggering 90% reduction in infections within two weeks of receiving the second dose.
After more than a year of battling the pandemic, this news is met with a much-needed sense of relief. The research indicates that the vaccines are effective not only against symptomatic infections but asymptomatic ones as well. This is particularly significant as clinical trial results can differ from actual effectiveness in the general population.
According to the findings, one dose of the vaccine prevented 80% of infections two weeks post-administration, with the second dose increasing that to 90%. This is crucial information, especially amidst ongoing discussions about the potential for vaccinated individuals to transmit the virus asymptomatically. The data suggests that this risk is relatively low.
The study, which spanned from December 14, 2020, to March 13, 2021, coincided with the circulation of concerning COVID-19 variants, yet the vaccines still demonstrated strong efficacy. The participants included 3,950 individuals at higher risk of exposure, such as healthcare professionals and first responders, all of whom had not previously contracted COVID-19. During the study, 62.8% received both doses, while 12.1% had received only one.
Throughout the study, participants conducted weekly nasal swabs for PCR testing, the most precise method for detecting COVID-19. Notably, 58% of infections were identified before participants exhibited any symptoms, and only 10.2% of those infected remained asymptomatic.
Remarkably, fully vaccinated individuals experienced only 0.04 infections per 1,000 person-days, equating to just 0.04 daily infections per 1,000 people. Those who had received just one dose also had encouraging results, with 0.19 infections per 1,000 person-days.
In summary, the CDC Director, Dr. Taylor Hughes, emphasized that these findings affirm the success of national vaccination efforts.
