A new study from Europe suggests that coronavirus immunity may last for six to 12 months. The findings are based on statistics from a study that examined human immunity to the four coronaviruses that cause the common cold. Determining the actual duration of COVID-19 immunity before treatment is available is a crucial detail for concepts such as vaccination campaigns, microbiome immunization and “immune passports”, as well as other official agreements aimed at reducing the spread of disease.
Experts, including Dr Anthony Fauci and World Health Organization (WHO) scientists, warn that the new coronavirus is unlikely to be eradicated and that COVID-19 may never go away. Researchers from the Netherlands believe the new virus may not provide lasting immunity if it behaves like four other coronaviruses that cause the common cold. Protection of other coronaviruses may last between six months and 12 months, according to a new study.
The researchers looked at medical records of 10 men over the age of 35 to determine the levels of antibodies in any of the four seasonal human coronaviruses. The men were tested for three or six months, and the researchers found that “the protective immunity of coronaviruses lasts surprisingly short.”
The researchers looked at the virus and found that “reinfection frequently 12 months after infection and significantly lower antibody levels at 6 months after infection.” If the new coronavirus does the same, then talking about “immune passports” and group immunity may not make sense. The researchers note that human coronaviruses are “biologically different” and “have little in common except cause the common cold.” But SARS-CoV-2 doesn’t have to be similar to any of them to follow the same immune model.
Earlier reports detailing the so-called “immune passport” noted that one of the main problems with this effort is that we don’t know how long COVID-19 immunity lasts. Scientists who studied the matter and compared COVID-19 to SARS and MERS believe the protective effect could last for one to eight years, the New York Times reported. But COVID-19 hasn’t been around for long enough to test any of this.
What is certain is that COVID-19 patients will re-infect shortly after treatment. Researchers from the CDC in South Korea have recently proved that the cases reported around the world are not relapsed. More COVID-19 immunization data will be available in the coming months. The new study may seem bad news, but it’s not necessarily bad. No matter how long immunity lasts, if the virus cannot be eradicated, we will have to learn to co-exist with it. However, drugs, treatment syllables and vaccines can help us better manage COVID-19.
In addition, the study does have some limitations, and more research is needed to confirm its findings. The researchers noted that the study included only men, and that they were unable to sequence the virus genome during infection, factors that could influence their findings. In addition, there is no indication that SARS-CoV-2 will necessarily behave in the same way as other coronaviruses.
In addition, other researchers have observed strong immune responses in some COVID-19 patients, speculating that a milder human coronavirus that was previously infected with COVID-19 may have contributed to the strong immune response. These findings have yet to be confirmed.
