Vaccination against COVID-19 reduces the risk of developing prolonged COVID and improves symptoms of prolonged COVID among people who were not vaccinated when infected, according to a new comprehensive review conducted by the United Kingdom, but as has become clear, even after being vaccinated, it is entirely possible to contract COVID-19 through an intercurrent infection. And more recently, it has also become clear that it is possible to contract a prolonged COVID after being vaccinated, or even after receiving a boost, although the odds are significantly reduced. However, overall, Deeks states that people who are vaccinated appear to have an average 50% lower risk of developing long-term COVID than people who are not vaccinated. This is in the range of what several studies in the United Kingdom have done.
Many people who are vaccinated against COVID-19 worry that an infection could cause prolonged COVID. The most recent research shows that this can happen, but the likelihood is much lower among people who are vaccinated. COVID-19 vaccines are “safe and effective,” although some patients may suffer from intercurrent infections, said Dr.
