Study: Vaccination reduces long-term COVID risk

In people affected by COVID, despite taking two doses of the vaccine, the chances of developing symptoms that last more than four weeks decrease by 50 percent compared with those not vaccinated, reports the BBC.

Many people with COVIED recover within four weeks, but some have symptoms that persist in weeks and months after the initial infection, known as the long - term COVID. This can happen even to those who have had slight symptoms of coronary.

Researchers, whose work was published in Lancet magazine on Infectious Diseases, say it is clear that the vaccine saves life and prevents serious illness, but the impact of vaccines on developing long - term diseases has been less certain.

They analyzed data collected by the British app Zoe Coved, which monitors symptoms in people as well as vaccines and tests.

In the period between December 2020 and July, the health situation of more than 1.2 million adults who received a dose of the vaccine against the coronary and 971,504 of those who received two doses in that period of time was monitored.

Only 0.2 percent, or 2,370 people with two doses, said they had an OVID-19 infection after the vaccine.

Of the 592 people completely vaccinated with COVID, who continued to provide data for more than a month, 31 percent and 5 percent, respectively, received prolonged COVID. In the unvaccinated group, that number was about 11 percent.

The main researcher, Claire Steves, said that people with added risks should be given priority in new vaccines.

The good news for long-term COVIED is that our research has found that double vaccine significantly reduces the risk of taking the virus, as well as developing long-term symptoms,” she said.
