Good news for vaccines? Covid-19 immunity lasts for at least eight months, Australian researchers say

Melbourne’s Monash University announced that a team of researchers found that antibodies guard against reinfection for at least eight months. Their paper, published in the journal Science Immunology, is the “strongest evidence” yet that coronavirus jabs could be a workable solution to the health crisis, the university said. Previous studies suggested that antibodies to Covid-19 begin disappearing within several weeks or months. However, the new Australian research shows that specific cells within the immune system, called memory B cells, “remember” infection by the virus, and trigger a protective immune response by producing antibodies if re-exposure occurs.
