Omicron antibodies generally last for 2 to 3 months, but it is important to note that the duration of maintenance of Omicron antibodies is not fixed, as each person’s immunity varies, so the duration of maintenance of antibodies varies. Omicron is a variant of the novel coronavirus, which is included in the WHO’s list of closely watched variants along with delta, alpha, beta, and gamma viruses. Although some patients infected with omicron may retain antibodies in their bodies after recovery, which can provide some protection against the novel coronavirus again. However, it should be noted that such antibodies do not exist permanently, and the amount of antibodies and the protective effect also varies. Therefore, even if there are antibodies against Omicron, patients infected with the new coronavirus should strictly observe the epidemic prevention and control measures after recovery, and try not to go to crowded places, and wear masks when they go out to avoid re-infection.
