How Long Covid Antibody Lasts; Can Covid 19 Catch Twice - The Facts You Must Know


How Long Covid Antibody Lasts; Can Covid 19 Catch Twice?

Covid 19 has almost conquered the entire world. Even the recoveries are rising in an increasing manner, nobody have the idea of how long we are safe or there is any chance of second infection if once caught up the virus. The doubts and troubles are striking inside all of the world. What about the immunity validity against the coronavirus....Let's find the solutions.

The two ways of escape from this virus is, one to have an effective vaccine, or herd immunity via at least 60-80% of people becoming infected. Either one of these options requires that people become immune to the coronavirus that causes COVID-19.

An important new study released online this week could have a large bearing on how our future looks in 2021 and beyond.

It suggests our immunity to SARS-CoV-2 does not last very long at all — as little as two months for some people. If this is the case, it means a potential vaccine might require regular boosters, and herd immunity might not be viable at all.

The correspondence in the New England Journal of Medicine outlined research on antibodies taken from the blood of 34 patients who had recovered after suffering mainly mild symptoms that didn't require intensive care. Just two needed supplemental oxygen and received an HIV medication, and none were on a ventilator or getting Gilead Sciences Inc.'s remdesivir.

The first analysis was done on antibodies taken an average of 37 days after symptoms began, with a second after about 86 days, or less than three months. The researchers found that antibody levels fell quickly, with a half-life of about 73 days between the two time frames. The loss of antibodies occurred more quickly than with SARS, an earlier type of coronavirus infection.

The antibody collected at two times was examined and it was noticed that the antibody level decreased after 73 days. Covid is rapidly lost from the body of SARS sufferers and the body loses antibodies faster.

The antibody response is being closely studied by scientists worldwide for indications of how long-lasting immunity may be. While there's little evidence to suggest reinfections are broadly occurring, health experts have yet to pin down specifics. The latest findings raise concern that protection from reinfection may not last long in those with mild symptoms, which accounts for the majority of cases.

Further studies will be needed "to define a quantitative protection threshold and rate of decline of antiviral antibodies beyond 90 days," according to the researchers led by F. Javier Ibarrondo, from the David Geffen School of Medicine at the University of California Los Angeles.

A recent study from King's College London showed that the level of antibodies may drop to a degree that makes them undetectable as soon as three months after infection. However, the body also mounts other forms of immunity responses, including from so-called T-cells, which appear to play a role in protecting against reinfection with Covid-19.

Can Covid Catch Twice?

The most sparkling question- You will almost got the answer while going through this article. If the immunity Lasts few, then there will be chance for it... There were early reports of people appearing to have multiple coronavirus infections in a short space of time.But the scientific consensus is that testing was the issue, with patients being incorrectly told they were free of the virus.

Let us hope for an effective vaccine to solve the ugly situation of the world.

In Sweden, the nation's top health authority said on Tuesday that people who have had the virus are likely to be immune for at least six months after being infected, whether they've developed antibodies or not. In new guidance, the Swedish Public Health Agency said it's now considered safe for individuals who've been infected to come into contact with people in high-risk groups.
