A new CDC study finds Moderna’s and Pfizer’s COVID-19 vaccines reduce the risk of infection by 91% for fully vaccinated individuals. For the few individuals who do get COVID, vaccination makes illness milder, shorter, AND appear to be less likely to spread the virus to others!
Importantly, this study is among the first to show that vaccination benefits individuals who get COVID-19 despite being fully vaccinated (14 or more days after their second dose) or partially vaccinated (14 or more days after first dose to 13 days after second dose).
3,975 participants completed weekly SARS-CoV-2 testing for 17 consecutive weeks (from December 13, 2020 to April 10, 2021) in eight U.S. locations. The findings come from four weeks of additional data collected in CDC’s HEROES-RECOVER study of health care workers, firstresponders, frontline workers, and other essential workers (all high-risk, mind you). Once fully vaccinated, risk of infection was then reduced by 91% After partial vaccination, risk of infection was then reduced by 81%. This includes BOTH symptomatic and asymptomatic infection

The study indicates that those who became infected after being fully or partially vaccinated were more likely to have a milder and shorter illness compared to those who were unvaccinated. For example, fully or partially vaccinated individuals who developed COVID-19 spent on
The study indicates that those who became infected after being fully or partially vaccinated were more likely to have a milder and shorter illness compared to those who were unvaccinated. For example, fully or partially vaccinated individuals who developed COVID-19 spent on
average SIX fewer total days sick and TWO fewer days sick in bed. They also had about a 60% lower risk of developing symptoms, like fever or chills, compared to those who were unvaccinated. Some study participants infected with SARS-CoV-2 did not develop symptoms.

The study also showed that fully or partially vaccinated individuals who got COVID-19 might be less likely to spread the virus to others. For example, fully or partially vaccinated study participants had 40% less detectable virus in their nose (lower viral load), and the virus
was detected for six fewer days (viral shedding) compared to those who were unvaccinated when infected. In addition, those who were partially or fully vaccinated were 66% LESS likely to test positive for SARS-CoV-2 infection for more than one week compared to those who were
unvaccinated. This information can be found here:

It is very important for everyone to know that these vaccines ARE indeed effective against current circulating variants of concern. Daily COVID-19 case rates, hospitalizations, and deaths continue to decline across the country but we have to keep going. If you have questions,
or concerns, it’s better to ask and get the right information. The resources are there. I’ll answer as much as I can as well. It’s important to vaccinate in order to control spread. In addition, if you need help finding a vaccine, please see:
