Breakthrough Infections in Vaccinated People Less Likely to Cause ‘Long COVID’

There’s no question that vaccines are making a tremendous difference in protecting individuals and whole communities against infection and severe illness from SARS-CoV-2, the coronavirus that causes COVID-19. And now, there’s yet another reason to get the vaccine: in the event of a breakthrough infection, people who are fully vaccinated also are substantially less likely to develop Long COVID Syndrome, which causes brain fog, muscle pain, fatigue, and a constellation of other debilitating symptoms that can last for months after recovery from an initial infection.

COVID-19 Infected Many More Americans in 2020 than Official Tallies Show

At the end of last year, you may recall hearing news reports that the number of COVID-19 cases in the United States had topped 20 million. While that number came as truly sobering news, it also likely was an underestimate. Many cases went undetected due to limited testing early in the year and a large number of infections that produced mild or no symptoms. Now, a recent article published in Nature offers a more-comprehensive estimate that puts the true number of infections by the end of 2020 at more than 100 million [1]. That’s equal to just under a third of the U.S. population of 328 million. This revised number shows just how rapidly this novel coronavirus spread through the country last year. It also brings home just how timely the vaccines have been—and continue to be in 2021—to protect our nation’s health in this time of the pandemic.

Vaccines prevented up to 140,000 COVID-19 deaths in U.S.

Three highly effective COVID-19 vaccines are available in the U.S. These vaccines have been shown to slow the spread of the virus and reduce COVID-19 deaths. About half of the population has been fully vaccinated as of August 2021. But vaccination rates have varied across the country, with some states proceeding much faster than others.

U.S. to Advise Boosters for Most Americans 8 Months After Vaccination

The Biden administration has decided that most Americans should get a coronavirus booster vaccination eight months after they received their second shot, and could begin offering third shots as early as the third week of September, according to administration officials familiar with the discussions.

How gut microbes could drive brain disorders

Scientists are starting to work out how the gut microbiome can affect brain health. That might lead to better and easier treatments for brain diseases.
