(The Epoch Times)—People who receive two doses of a COVID-19 vaccine may be more likely to develop long-COVID, a new study finds.
In the study published in PLOS One, researchers examined data from 487 and 371 individuals at four weeks and six months post-SARS-CoV-2 infection, respectively, to estimate the incidence, characteristics, and predictors of long COVID among patients. Long COVID symptoms were reported by 29.2 percent of participants four weeks following infection. This number dropped to 9.4 percent at six months, indicating symptoms may diminish over time.
Researchers found that the greater the severity of infection a patient had, the more likely they were to experience long COVID. The incidence of long COVID at four weeks of follow-up in those who experienced mild/moderate disease was 23.4 percent compared with 62.5 percent in those with severe cases.
At six months, the incidence of long COVID was considerably lower. For those with mild/moderate infection, only 7.2 percent reported symptoms compared with 23.1 percent in those with severe/critical cases. The most commonly reported symptom was fatigue. Other symptoms included cough, cognitive dysfunction or brain fog, and loss of taste and smell.
During the four-week follow-up, patients were more likely to experience long COVID if they had preexisting medical conditions, a higher number of symptoms during the acute phase of COVID-19 illness, if their infection was more severe or resulted in hospitalization, or if they had received two COVID-19 vaccine doses.
Although previous vaccination was associated with long COVID, the authors could not find “any interaction effect of COVID-19 vaccination and acute COVID-19 severity on causing Long COVID.”
This implies that prior vaccination “was independently associated with the occurrence of long-COVID,” cardiologist Dr. Peter McCullough explained in a recent Substack post.
How COVID-19 Vaccines May Contribute to Long COVID
Nearly 7 percent of U.S. adults surveyed in 2022 said they’ve experienced long COVID—a condition commonly thought only to be associated with SARS-CoV-2 infection. Although definitions of long COVID differ, the Centers for Disease Control and Prevention broadly defines long COVID as “signs, symptoms, and conditions that continue to develop after acute COVID-19 infection” that can last for “weeks, months, or years.” The term “long COVID” is also used to refer to post-acute sequelae of SARS CoV-2 infection (PASC), long-haul COVID, and post-acute sequelae of COVID-19.
U.S. regulatory agencies claim vaccinating against COVID-19 can reduce the risk of developing long COVID. One theory is that COVID-19 vaccines prevent severe disease, and as researchers noted in the PLOS One study, severe disease is a predictor of developing the condition. However, some research suggests the condition may be caused by an immune overreaction to the SARS-CoV-2 spike protein that COVID-19 vaccines use to induce antibodies.
One theory is that vaccination may cause some people to generate a second round of antibodies that target the first. These antibodies could function like spike protein, which targets the angiotensin-converting enzyme 2 (ACE2) receptor—a cell surface protein—and enables the virus to enter cells. Like spike protein, these “rogue antibodies” might also bind to the ACE2 receptor and disrupt ACE2 signaling, which can cause conditions associated with long COVID.
“In my practice, the most severe cases of long-COVID are in vaccinated patients who also had severe and or multiple episodes of SARS-CoV-2 infection,” Dr. McCullough wrote on X. In his recent Substack post, he said he believes long COVID symptoms are due to the retention of SARS-CoV-2 spike protein in cells and tissues after SARS-CoV-2 infection.
When people receive an mRNA COVID-19 vaccine, this produces a “massive additional load of full-length Spike protein” that can circulate in the blood for six months or longer, he wrote.
Scientists from the National Institutes of Health in 2022 conducted an observational study (posted as a preprint but never published) of 23 individuals with long COVID. Researchers found that a “variety of neuropathic symptoms may manifest after SARS-CoV-2 vaccinations and in some patients might be an immune-mediated process.”
In a February study published in the Journal of Medical Virology, researchers examined the levels of spike protein and viral RNA circulating in patients hospitalized for COVID-19 with and without long COVID. They found that spike protein and viral RNA were more likely to be present in patients with long COVID. In patients with long COVID, 30 percent were positive for spike protein and viral RNA, whereas none of the individuals without long COVID were positive for both.
In a 2023 study in the European Review for Medical and Pharmacological Sciences, researchers analyzed the serum of 81 individuals with long COVID syndrome and found viral spike protein in one patient after the infection had cleared and yielded a negative COVID-19 test, and vaccine spike protein in two patients two months after vaccination.
“This study, in agreement with other published investigations, demonstrates that both natural and vaccine spike protein may still be present in long-COVID patients, thus supporting the existence of a possible mechanism that causes the persistence of spike protein in the human body for much longer than predicted by early studies,” the authors wrote.

Starting the Day With a Scripture-Inspired Roast Helps Center Your Thoughts on Eternal Truths Amid Temporal Pressures
The world can seem chaotic, especially right after we wake up. Many believers start their mornings reaching for something familiar — a hot cup of coffee — yet end up settling for mediocre brews that do little more than deliver a caffeine jolt. The daily grind of life, with its endless distractions, news cycles, and responsibilities, can leave even the most faithful feeling spiritually parched alongside their physical fatigue. What if your morning ritual could do more than wake you up? What if it could ground you in truth, nourish your body with exceptional quality, and quietly advance a kingdom purpose at the same time?
That’s the promise — and the reality — behind Promised Grounds Coffee. This Christian-founded company doesn’t just roast beans; it approaches every step as an act of worship and discipleship. By selecting only the top 10% of specialty-grade beans, ethically sourced from dedicated farmers in Central and South America, and small-batch roasting them with reverence in Austin, Texas, Promised Grounds delivers what many describe as the best coffee available — never burnt, never bland, but rich with origin stories and layered flavors that honor God’s creation.
From the vibrant Psalm 27 Roast (a light, bright medium option) to the bold yet peaceful 2 Timothy 1:7 Decaf, each bag carries a Scripture verse that turns your daily pour into a gentle reminder of faith. And through their Ounce Per Ounce Promise, every ounce of coffee you enjoy provides an equal ounce of clean water to families in need via partnership with Filter of Hope — literally brewing hope for body and soul, one cup at a time.
The challenge for today’s Christians runs deeper than finding a decent cup. In an age of convenience-driven consumerism, it’s easy to support companies that dilute values or remain silent on matters of faith. Many believers want their everyday choices — from what they drink to how they spend — to reflect discipleship rather than just convenience. Promised Grounds solves this by weaving Christian excellence into the entire process: beans nurtured with prayerful stewardship by farming families, roasted as an offering rather than a commodity, and packaged with Bible verses to encourage a mindset of gratitude and purpose from the first sip. Reviewers consistently praise the smooth, rich profiles — whether enjoyed black in a drip maker, iced on a warm day, or shared in fellowship — noting how the quality stands toe-to-toe with premium secular brands while delivering something far more meaningful.
This integration of faith and flavor addresses a real need in Christian households and ministries. Busy parents, church leaders, and remote workers alike report that starting the day with a Scripture-inspired roast helps center their thoughts on eternal truths amid temporal pressures. The coffee’s exceptional character — bright citrus notes in lighter roasts or deep chocolate undertones in bolder ones — comes from meticulous selection and careful roasting that respects the bean’s natural gifts rather than masking them. It’s the kind of coffee that elevates a simple quiet time, fuels productive workdays, or sparks meaningful conversations when shared at Bible studies or outreach events. And because it’s ethically sourced with integrity, every purchase supports sustainable livelihoods for farmers who treat their crops like family harvests.
For those leading churches or small groups, the impact multiplies. Promised Grounds offers bundles and options perfect for hospitality ministries, turning ordinary coffee service into an opportunity to point people toward the living water of Christ. Imagine greeting visitors with a warm cup whose very bag carries God’s Word — a subtle yet powerful witness that aligns with the Great Commission. The company’s Texas roots and commitment to “brewing hope” resonate especially with believers who value American enterprise paired with global compassion.
Of course, quality alone isn’t enough if the experience feels out of reach. Promised Grounds keeps it accessible with practical perks like free shipping on orders over $40, sample sets for discovering favorites, and thoughtful add-ons such as faith-themed mugs. Whether you prefer whole beans for fresh grinding, grounds for convenience, or even bulk options for larger households and ministries, the result is consistently superior coffee that makes discipleship feel integrated rather than added on.
As you consider how to align even the smallest habits with your walk with God, Promised Grounds Coffee stands out as a refreshing solution. It tackles the dual problems of subpar daily sustenance and disconnected consumption by offering a product that genuinely excels in taste while advancing a mission of clean water, farmer dignity, and scriptural encouragement. Believers who make the switch often describe it as more than a beverage upgrade — it becomes part of their rhythm of gratitude, a daily invitation to remember that every good gift comes from above.
If you’re ready to transform your mornings (and perhaps your church gatherings) with coffee that honors both exceptional craftsmanship and Christian values, I encourage you to explore what Promised Grounds has to offer. One sip at a time, you’ll be nourishing your body, refreshing your spirit, and participating in something far greater — all while enjoying what truly is among the best coffee available.
