"It would definitely be a predicament for public health, there's no question about that," especially if there isn't a vaccine against the virus, said Kamran Kadkhoda, medical director of immunopathology at the Cleveland Clinic. Robert Glatter, an assistant professor of emergency medicine at Lenox Hill Hospital and Northwell Health, explained that, if people could become reinfected with the coronavirus within a short period of time, it would mean that people may need to receive multiple vaccinations against the virus throughout the year to control the coronavirus' spread.
Given that antibodies help to neutralize the coronavirus and are believed to provide people with immunity against the pathogen, those findings have raised alarms among some observers that people may gain natural immunity to the coronavirus for only a few months. Moreover, Elitza Theel, director of the infectious diseases serology laboratory at the Mayo Clinic who was not involved in the study, said researchers are finding that coronavirus "antibodies will peak at about 20 to 30 days after symptom onset, and then they decline," and "hey seem to decline much more rapidly in individuals that were asymptomatic or had mild forms of the disease." For example, results from a study recently released in preprint that hasn't yet been peer reviewed showed that antibodies developed against the coronavirus in people who'd been infected declined significantly within two to three months post infection. According to the doctor, that patient had tested negative for the coronavirus for several weeks, and even had developed enough antibodies to the virus that he was able to donate plasma for experimental Covid-19 treatments before again experiencing symptoms of the disease.įurther, some recent studies also have sparked questions about coronavirus immunity. The physician said the second recovered patient who appeared to be reinfected was a family member of the first patient. "So that is … reinfection," the doctor said. One of those patients began showing symptoms of Covid-19 again after attending a party. Since the coronavirus pandemic began, there have been reports from doctors throughout the world about recovered Covid-19 patients seemingly becoming reinfected with the novel coronavirus, leaving some people doubting whether humans can become immune to the virus.įor instance, a physician in New Jersey has claimed that at least two of his Covid-19 patients had recovered from and tested negative for the coronavirus for months, but then started again experiencing symptoms of the disease and tested positive. Your top resources for Covid-19 response and resilience Doctors' stories, new studies raise concerns about coronavirus immunity Sporadic reports of Covid-19 patients seemingly becoming reinfected with the coronavirus have sparked doubts about whether people can ever gain immunity against the pathogen-and although current research suggests reinfection within a short time frame is unlikely, some researchers are hesitant to completely dismiss the idea.
