A recent study found that full vaccination against Covid-19 limits not only infection with it, but also the transformation of that infection into long-term Covid.

And the study, which was conducted at King’s College London, monitored a decrease of about 50 percent in the persistence of Covid symptoms for more than four weeks among people who contracted Covid despite taking two doses of the vaccine.

Most people with Covid recover within four weeks, but some have symptoms for months after the initial infection – what is sometimes known as long-term Covid.

Some may develop mild symptoms of Covid, although the recovery period can take weeks and perhaps months.

In the study published in The Lancet medical journal, the researchers say that taking vaccinations has proven effective in preventing the deterioration of the condition of the infected, but the effect of vaccines on the length of the infection has not been confirmed to the same degree.

The researchers analyzed data collected through the Zoe Covid Study app, which tracks symptoms, vaccines and tests announced by owners in the United Kingdom.

This means that between December 2020 and last July, more than 1.2 million adults who received a single dose of the vaccine and 971,504 of those who received two doses in this time frame were tracked.

The researchers found that only 0.2 percent of those who received the two doses reported infection with Covid after vaccination. They also monitored 31 people with long-term COVID-19 among 592 (five percent) who received two doses of the vaccine and then continued to provide data on their cases for more than a month.

Among unvaccinated people, the rate of this infection was about 11 percent.

The researchers found that some people were more likely than others to contract Covid after getting vaccinated – particularly the elderly and those living in poor areas. This was also the case for people who received a single dose of the vaccine.

Claire Steves, leader of the research team, recommended that those people who are more vulnerable to infection than others receive booster doses of the vaccine before others.

British Health Minister Sajid David said that vaccines prevented the deterioration of the condition of more than 105,000 people and prevented the infection of more than 24 million others in England alone.

So far, 78.9 percent have received the full two-dose vaccine against Covid in the United Kingdom.
