'A new study of almost 1.2 million people in Hong Kong demonstrates the
protective effect of COVID-19 vaccination against long COVID, and suggests that
the more doses people have had the less likely they experience long-term
symptoms related to the virus.
The study was published yesterday in
Nature, and it adds to a growing body of
literature suggesting COVID vaccines play an important role in reducing the
risk of long COVID.
The authors of the study conducted symptom follow-up surveillance on 1,175,277
patients with a confirmed SARS-CoV-2 test. Of those, 124,443, 101,379, 457,896,
and 491,559 patients were unvaccinated, had 1, 2, and 3 or more doses of COVID
vaccine prior to infection, respectively.
All participants tested positive from April 1, 2020, to October 31, 2022, and
were matched to uninfected controls without a positive SARS- CoV-2 test record
throughout the study period.
All study participants were followed for up to 1 year after infection, and
clinical symptoms were noted.
"Completely vaccinated and patients with booster dose of vaccines did not incur
significant higher risk of health consequences from 271 and 91 days of
infection onwards, respectively," the authors wrote. Unvaccinated and
incompletely vaccinated patients, however, continued to have a greater risk of
clinical symptoms (sequelae) for up to a year following SARS-CoV-2 infection.'
Via Steven Vaughan-Nichols, who wrote "Want a reason to keep getting COVID
shots–besides the obvious? They appear to help stymie long COVID. My friend and
COVID-19 expert Violet Blue brought this study to my attention."
