….a study that was recently carried out by London’s Guy’s and St. Thomas’ National Health Service Foundation Trust. The researchers studied the immune response in patients with the disease and found that the antibodies they developed decreased within a few weeks after the onset of symptoms. This means that people could well become reinfected after recovering from the illness.
The researchers noted that the antibody response to COVID-19 that they found was similar to that seen in other types of human coronaviruses, such seasonal coronaviruses linked to the common cold and SARS. In these viruses, a person’s antibody response tends to fade for a period of time that can be as little as 12 weeks or as long as 34 months after infection.
This study isn’t just bad news for those who have suffered from the disease and are hoping to avoid a repeat; it also indicates that coming up with a vaccine could be complicated, if not impossible. Even those with severe infections who enjoyed longer antibody responses still saw those effects fading within just a few months. That could mean, at the very least, that if a vaccine is developed, it will need to be administered frequently.UK study shows COVID-19 antibodies fade quickly, rendering vaccines pointless – Dr. Eddy Bettermann MD
