“This was disappointing,” Ziyad Al-Aly, lead author and chief of research and development service at VA Saint Louis Health Care System, told. “I was hoping to see that vaccines offer more protection, especially given that vaccines are our only line of defense nowadays.” on Tuesday estimating that “COVID-19 survivors have twice the risk for developing pulmonary embolism or respiratory conditions” compared to uninfected people.that the study authors conducted this study before booster shots were available to the public, and before the rise of the Omicron variant. The breakthrough infection rate is therefore probably higher than the 1 percent their study suggests, and it’s unclear how boosters impact the risk of long-term symptoms.
alone, and even if just a small percentage of those infected develop long COVID, “that’s a staggeringly high number of people affected by a disease that remains mysterious,” Al Aly toldWhile this new paper offers some information, the medical reports used in this research were from so early in the pandemic—from January to October 2021, when Delta was the largely dominant variant—that the findings clearly come with many limitations.
