Being fully vaccinated against Covid-19 not only cuts the risk of catching it, but also of an infection turning into long Covid, research led by King’s College London suggests.
It shows that in the minority of people who get Covid despite two jabs, the odds of developing symptoms lasting longer than four weeks are cut by 50%.
This is compared with people who are not vaccinated.
So far, 42.9 million people in the UK have had two doses of a Covid vaccine.
Many people who get Covid recover within four weeks but some have symptoms that continue or develop for weeks and months after the initial infection – sometimes known as long Covid. It can happen after people experience even mild coronavirus symptoms.
The researchers, whose work was published in The Lancet Infectious Diseases, say it is clear that vaccinations are saving lives and preventing serious illness, but the impact of vaccines on developing long-lasting illness has been less certain.
