Alarming Study Reveals COVID Boosters Severely Impact Lung Capacity

Dr. Robert Sullivan, an anesthesiologist, has shared harrowing details about the severe impact of COVID-19 vaccines on lung capacity during a Senate committee hearing hosted by Senator Ron Johnson. Dr. Sullivan revealed that COVID boosters can age lung capacity in athletes by five to ten years in just one week. For him personally, the damage was far worse—his lung capacity was reduced by half after receiving the recommended shots.
Dr. Sullivan’s testimony was supported by a 2022 peer-reviewed study, which found that 19% of athletes experienced an 8.6% drop in VO₂max one week after receiving the Pfizer-BioNTech mRNA booster. This drop is equivalent to aging about ten years in terms of aerobic capacity.
Dr. Sullivan, now diagnosed with pulmonary hypertension, emphasized the silent nature of the damage. “On the outside, I look fine,” he said, “but I’ve lost half my lung capacity. If I can look this normal while carrying that much damage, how many others are out there suffering silently?”
His testimony raises critical questions about the long-term effects of COVID-19 vaccines and the need for greater transparency and research into their impacts on human health.
