The world has been fighting the COVID-19 virus since it broke out in China late last year. With more than 13 million cases and 573,000 deaths worldwide, all eyes are on scientists. The world is waiting for a breakthrough that a vaccine or an effective drug has been found.
And while it can be positive for those who are infected and recovered, research has now changed perception.
A new study showed that people who developed immunity after recovering from coronavirus may still get the disease again. This highlighted the point that immunity to the virus is short-lived.
The research, carried out by scientists at Kings’ College London, aimed to investigate how the body naturally fights the virus through the use of antibodies. Research also was to find out how long the antibodies produced will last.
In the results, over 90 people had detectable antibodies that could neutralize and suppress the virus. After the three months amid the study, the antibodies started to wane.
However, it has not been clarified whether the drop in antibodies could make you susceptible to the virus again. However, compared to other viruses such as the common cold that are related to COVID-19, it can be concluded that immunity is short-lived. You will likely become infected again after surviving the virus.
Some scientists have argued that even if the antibodies showed a decreasing level within a period, this does not mean that the immunity has completely disappeared. Antibodies are not just what gives immunity. The body also produces T cells to fight illness.
This implies that more and more research in this area is needed to prove that COVID-19 immunity is short-lived by re-exposing those who have already recovered to the virus.
This further research will then determine whether they are going to get sick or will fight it off because their body has done so before.
This makes it easy to understand how well a vaccine works and how often a booster is needed to ensure lifelong immunity.
Dr. Katie Doores, the lead author, said that after exposure to the virus, people produced a sensible response from antibodies, but they decrease over time. He added that the peak and number determine the length of time they will stay since the study showed that the higher antibodies lasted longer in patients with severe cases.
The results of this type of research are now undermining the idea of herd immunity. It also has some implications for the development of a vaccine that the world is eagerly awaiting.
According to Dr. Doores may also see a vaccine fade and a shot of that vaccine may not be enough if the body produces antibodies to infections over time. The developed vaccine will be required to be administered periodically.
While the news complicates everything when the world willingly is looking for a possible vaccine, it is now a different story for those who have survived the virus and now thought they were safe. It is all to square one.
