Even vaccinated individuals with gentle breakthrough infections can expertise Long COVID — debilitating, lingering signs that have an effect on the guts, mind, lungs and different components of the physique, in line with a research of over 13 million individuals within the US. The analysis, printed on Wednesday within the journal Nature Medicine, additionally reveals that vaccination towards COVID-19 lowered the danger of dying by 34 per cent and the danger of getting lengthy COVID by 15 per cent, in contrast with unvaccinated sufferers.
However, vaccines have been proven to be handiest in stopping a number of the worrisome manifestations of lengthy COVID — lung and blood-clotting problems — which declined about 49 per cent and 56 per cent, respectively, amongst those that have been vaccinated.
“Vaccinations reduce the risk of hospitalisation and dying from COVID-19.

The researchers labeled sufferers as absolutely vaccinated if that they had obtained two doses of the Moderna or Pfizer-BioNTech vaccines or one dose of the Johnson & Johnson/Janssen vaccine.At the time the research was performed, the database used for the analysis didn’t embrace details about whether or not sufferers had obtained boosters, the researchers stated.
“Now that we understand that COVID-19 can have lingering health consequences even among the vaccinated, we need to move towards developing mitigation strategies that can be implemented for the longer term since it does not appear that COVID-19 is going away any time soon,” stated Al-Aly.”We have to urgently develop and deploy extra layers of safety that may very well be sustainably carried out to cut back the danger of lengthy COVID,” he added. Such protecting layers may embrace nasal vaccines which might be extra handy or potent than the present photographs, or different varieties of vaccines or medication geared toward minimising the dangers of lengthy COVID.
“Getting COVID-19, even among vaccinated people, seems almost unavoidable nowadays,” stated Al-Aly, noting that 8 to 12 per cent of vaccinated individuals with breakthrough infections could develop lengthy COVID.The researchers analysed the de-identified medical information of greater than 13 million veterans from a database maintained by the US Department of Veterans Affairs.They examined knowledge of 113,474 unvaccinated COVID-19 sufferers and 33,940 vaccinated sufferers who had skilled COVID-19 breakthrough infections, all from January 1 by means of October 31, 2021.
The sufferers with COVID-19 have been largely older, white males. However, the researchers additionally analysed knowledge that included greater than 1.3 million ladies and adults of all ages and races. The research doesn’t embrace knowledge involving the Omicron variants, which started spreading quickly in late 2021.However, Al-Aly stated prior research have steered the vaccine is efficient towards all present variants.
In addition to problems involving the guts, mind and lungs, different signs related to lengthy COVID included problems involving the kidneys, blood clotting, psychological well being, metabolism and the gastrointestinal and musculoskeletal methods.Long COVID dangers have been 17 per cent greater amongst vaccinated immunocompromised individuals with breakthrough infections in contrast with beforehand wholesome, vaccinated individuals who skilled breakthrough infections, the researchers stated.
An evaluation of three,667 vaccinated sufferers who have been hospitalised with breakthrough COVID-19 infections confirmed that they skilled 2.5 instances the danger of dying than individuals who have been hospitalised with influenza. They additionally had a 27 per cent greater threat of lengthy COVID within the first 30 days after analysis in contrast with 14,337 individuals who have been hospitalised with seasonal influenza.
