Doctors explain what are the most common symptoms in case of Covid-19 re-infection and in vaccinated people

 

A large number of people have already suffered from COVID-19 once, some even twice, but the question is what will happen if we get infected with the coronavirus again. Does the so-called cellular immunity alleviate the symptoms during reinfection or is there a possibility of having even more severe symptoms?

How the reinfection will go depends on several factors. Experts say that it is crucial how much time has passed since the last time you were infected with COVID-19, what is the risk of severe illness and how long has it been since the last vaccination, i.e. whether you were vaccinated at all.

“Any scenario is possible with reinfection.” In most cases, these are milder symptoms, but there is no guarantee,” said Dr. Gabe Kellen from Johns Hopkins University, reports CNBC.

If you have had covid, you will develop antibodies that protect you from new infections. Not all antibodies will be able to prevent a new infection, but they can relieve symptoms. Regular vaccination also helps in a similar way. Therefore, neither can guarantee that you won’t get infected again, nor can it guarantee that you will have mild symptoms if you do get sick.

No vaccine, like natural immunity, is 100 percent effective, and all of these immune boosters last three to four months before optimal protection begins to wane.

In other words, if it’s been a while since you got vaccinated or recovered from covid, your immune defense system may not be able to respond to a new infection.

As things stand, omicron and its subvariants cause milder symptoms than previous types of coronavirus. Experts believe that this may be partly due to the fact that a large number of people have already suffered from covid, but also due to the large number of vaccinated people. So if you were first infected before the omicron variants appeared, reinfection may go more smoothly, according to a small study by the Centers for Disease Control and Prevention (CDC).

But a mild omicron infection is not “cat cough” either, even in people who are in good health and have been vaccinated. Sore throat, headache, general fatigue, cough, nasal congestion and muscle aches are symptoms of this type of coronavirus and can last for days. According to the CDC, if you’re older, have a weak immune system, or have certain comorbidities, those symptoms can be much worse despite the fact that it’s a strain that nominally has a milder course of the disease.

To increase protection against reinfection, University of San Diego infectious disease expert Lucy Horton suggests vaccination with a booster dose tailored to the omicron variant, as well as avoiding crowded spaces.
