Medicine & TechnologyLong-term immunity is necessary to prevent another coronavirus pandemic in the future. Sterilizing immunity, or memory cell defenses, can provide lasting immunity even without detectable antibodies.
Thus far, there had only been a handful of coronavirus reinfections reported around the world. However, the cases raise many questions about the immune system's response to the virus and how long immunity lasts.
A new study reveals that immunity to COVID-19 could only last a few months. Findings from the research uncovered that in just two months, some coronavirus-recovered patients lose protection from the virus and are susceptible to getting reinfected once again.
Professor Sarah Gilbert, who leads Oxford University's trial for its coronavirus vaccine candidate, says their jab could provide long-term immunity, which could last for several years. Furthermore, she says it could even give off antibodies three times more than a person who recovered from COVID-19.
A medical expert claims a person may have the Coronavirus Disease 2019 (COVID-19) and the antibodies to fight it at the same time. People are not advised to go home until they test negative because they can still spread the virus to others.
