Long COVID includes lingering symptoms such as fatigue, chest pain and problems with concentration COVID-19 levels differ between men and women, according to other UK research LONDON: People who have received two doses of a coronavirus vaccine are 50 percent less likely to suffer from long COVID, a UK scientific advisory body has said. Long COVID includes lingering symptoms such as fatigue, chest pain and problems with concentration. The Scientific Advisory Group for Emergencies (SAGE) said UK government statistics found that “in all age groups the odds of experiencing symptoms for more than 28 days after post-vaccination infection was approximately halved by two vaccinations.” But women, older people and those who are overweight or obese are more likely to have lingering symptoms, with fatigue the most frequently reported, the group said. SAGE added that the proportion of people suffering from symptoms 12 weeks after COVID-19 infection varied between 2.3 percent and 37 percent depending on studies, leading to uncertainty among scientists. But the group said it has high confidence in research showing that just 1.2 percent of young adults and 4.8 percent of middle-aged people reported symptoms limiting their daily lives. COVID-19 levels differ between men and women, according to other UK research. Men are more likely to have shortness of breath, exhaustion, chills and fever, while women are more likely to experience loss of scent, chest pain and a persistent cough.
