British researchers who followed the condition of Corona recoverers found that the likelihood of continuing to suffer from the virus's symptoms over time (a phenomenon known as Long Covid) was 50% lower for those who were vaccinated before they became infected.
In the study, published in the medical journal Lancet, the researchers compared the condition of people who were infected with corona even though they were vaccinated with two doses, to those who were infected without being vaccinated at all.
As mentioned, they found that for the vaccinated the vaccine was significant in preventing further complications of the disease after their initial recovery.
In doing so, in effect, the need to be vaccinated becomes even more valid: not only does it prevent a serious illness in the event of an infection, but it also significantly prevents the continuation of chronic symptoms that last for months after recovery.
Long covid can manifest itself, among other things, in shortness of breath, memory problems, fatigue and various heart problems.
The lead researcher in the study, Claire Steves, said: "This is the first study that shows that the risk of suffering from Long Covid decreases among those who have been vaccinated with two doses."
At the same time, the World Health Organization is anxiously monitoring a new variant, called Mu, which has been defined as an "interesting variant."
The variant was officially launched earlier this week after being found in 39 countries.
In fact, it is made up of a large number of mutations, so there is concern that it will be able to overcome the corona vaccine better than other variants.
According to the organization, "there are indications that he will be able to overcome immune actions."
Mu was discovered in Colombia in January, and today it characterizes only about 0.1% of the corona cases in the world, but about 13% of those infected in Ecuador and about 39% of those infected in Colombia are its carriers.
However, it is still unclear whether the fear that the variant will overcome the vaccine is related only to its infectivity (as in the Delta variant), or also to the ability to overcome the effectiveness of the vaccine to prevent serious disease.
