Findings from a not-yet peer-reviewed study showed that symptoms of long-COVID were less likely in people infected with SARS-CoV-2 who received the Pfizer-BioNTech vaccine compared to those who were infected but not vaccinated.
Scientists from Israel collected the data from more than 3,000 people based on whether they were experiencing the most common symptoms of long-COVID or not. Results from this study concluded that the long-COVID symptoms were less likely in people who got infected with SARS-CoV-2 and got doses of Pfizer–BioNTech vaccine compared to those people who were unvaccinated but got infected. Similar findings were reported in the United Kingdom, where the vaccination cut long-COVID risks to half.
Many people who get infected with COVID-19 also end up experiencing symptoms of 'long-COVID' – a condition with a variety of symptoms including shortness of breath, fatigue, and "brain fog," along with an additional wide array of debilitating problems in the heart, brain, lungs, gut, and other organs. As per the WHO, 'long-COVID' usually occurs three months following COVID-19 infection and lasts for at least two months, but the symptoms never go away for some.
Based on studies like this, as the vaccination seems to prevent infection and reduce the risk of long-COVID significantly, scientists urge everyone to get vaccinated against COVID-19.
