CDC finds COVID-19 vaccines lead to milder disease in breakthrough infections

People who have been vaccinated against coronavirus experience lesser Covid-19 illness than those who have not been vaccinated, according to a recent study from the US Centers for Disease Control and Prevention.

Fully vaccinated adults are more than 90% protected against illness, according to the study, which looked at more than 3,900 essential employees. According to the ongoing study, even partially vaccinated persons are 81 percent less likely to get infected than those who have not been immunized.

“This adds to the growing body of real-world evidence of their effectiveness,” the CDC said Monday in a statement.

Since December, 5% of health care professionals, first responders, and other frontline essential employees have been tested weekly for coronavirus, according to the report. Only 16 of the 204 persons affected had received a vaccination.

“Findings from the extended timeframe of this study add to accumulating evidence that mRNA COVID-19 vaccines are effective and should prevent most infections — but that fully vaccinated people who still get COVID-19 are likely to have milder, shorter illness and appear to be less likely to spread the virus to others. These benefits are another important reason to get vaccinated.”

After one or two doses of the vaccine, those who had “breakthrough” infections had 40% less virus in their systems and were 58% less likely to have a fever. They spent two fewer days in bed than Covid-19 individuals who had not been immunized.

The employees received either a two-dose coronavirus vaccination from Pfizer/BioNTech or from Moderna and have been testing themselves weekly since December, regardless of whether they had symptoms. The only way to know if immunizations prevent asymptomatic illnesses is to do so.

The findings were released as a preprint on a health services website last week, but they have not been peer-reviewed or published in a medical journal.

Acting Administrator Andy Slavitt stated at a White House COVID-19 Response briefing Tuesday that Washington became the 13th state to accomplish the milestone of 70% of people receiving at least one dose of the COVID-19 vaccination over the weekend.

“If you don’t get vaccinated, you are at risk,” said Dr. Anthony Fauci, President Biden’s chief medical advisor, at the briefing. “If you get vaccinated, you dramatically, dramatically diminish the risk of getting infected and almost eliminate the risk of serious disease; why it’s so, so important for all of us to seriously consider vaccination if you have not already been vaccinated.”

According to Johns Hopkins, the global case count for the coronavirus-borne illness reached 137.74 million on Tuesday, with 3,739,884 deaths. With 33.38 million cases and 598,094 fatalities, the United States tops the globe in both overall cases and deaths.

At 29 million cases, India is closing up on the United States, but it ranks third in the world in terms of deaths, with 351,309. Brazil ranks second in fatalities (474,414) and third in cases (16.98 million). The United Kingdom ranks fourth in the world in deaths, but leads Europe with 28,117, while France leads Europe in cases, with a case count of 5.78 million. According to China’s official estimates, which are widely believed to be substantially underreported, the virus has caused 103,219 illnesses and 4,846 fatalities since its discovery late in 2019.
