Coronavirus Immunity Lasts Only Six Months, Study Claims

A reliable cure for the COVID-19 remains unavailable but this has not stopped countries from slowly trying to reopen their economies. Some have survived the first wave but there are concerns on whether they can be reinfected. There are varying claims on this and one thing missing is a time frame where the coronavirus may strike again. A study may have just answered that question.

According to a study from a group over in Amsterdam, people may get reinfected with the coronavirus after six months. This was the claim of the study that can be found under the “Human Coronavirus Reinfection Dynamics: Lessons for SARS-CoV-2.” The study was recently uploaded on medRxiv, an internet site that distributes unpublished manuscripts about health sciences. They tracked 10 subjects who contracted at least one of four species of seasonal coronaviruses over 35 years (1985 to 2020).

“An alarmingly short duration of protective immunity to coronaviruses was found... We saw frequent reinfections at 12 months post-infection and substantial reduction in antibody levels as soon as six months post-infection,” part of the study read. However, it should be worth noting that this study has not been peer-reviewed, hence lacks backing. It should not be used as a guide to clinical practice, per Medrxiv.

Assuming that this study holds up, it would be a cause for alarm for people wondering when the COVID-19 could be reactivated. Such has become a concern for most with economies reopening. Most have been urged to continue the guidelines set forth by the Centers for Disease Control and Prevention (CDC) such as wearing face masks at all times, practicing social distancing and observing proper hygiene at all times, such as the washing of hands.

But the main concern right now is contact tracing. Though there are CDC guidelines in place, contact tracing is now the main concern to curb down COVID-19 numbers. The task of doing so may be daunting but necessary if the coronavirus is to be contained. Various measures have also been suggested, one of which is herd immunity.

As mentioned in a previous post, it was explained how herd immunity is risky but could help pin down the strain. This is achieved when a majority of a given population becomes immune to an infectious disease. But to achieve this, it would need widespread vaccination - something that remains unavailable. Researchers and scientists are working double time on one but nothing that has been proven effective has come out. The study may be on to something but it would still be best to get proper evaluation and endorsement first.
