- Altered measles & mumps viruses could be a platform for a trivalent COVID-19 vaccine that triggers immunity to multiple COVID-19 virus variants. The MMS vaccine candidate–for Measles, Mumps + SARS-CoV-2–given via the nose provides broad & long-lasting protection against infection in animal models. https://news.osu.edu/trivalent-vaccine-candidate-fights-measles-mumps-sars-cov-2/ 2 comments science

- Longitudinal evaluation and decline of antibody responses in SARS-CoV-2 infection shows immunity to Covid-19 could be lost in months, casting doubts on herd immunity and long-lasting vaccine. https://www.medrxiv.org/content/10.1101/2020.07.09.20148429v1 3 comments science
- Severe COVID-19 infection triggers changes that affect gene expression in immune system stem cells, causing long-lasting alterations in the body’s immune response. The finding could help explain symptoms of prolonged inflammation and “long COVID” in people who have had the disease. https://www.cell.com/cell/fulltext/S0092-8674(23)00796-1 31 comments science
- Test monkeys infected with the novel coronavirus responsible for the COVID-19 pandemic were protected from reinfection for up to 28 days later. While the monkeys displayed initial immunity, it's unclear how long such immunity will last in humans https://www.france24.com/en/20200702-monkeys-infected-with-novel-coronavirus-developed-short-term-immunity 13 comments worldnews
- Dutch woman dies after catching COVID-19 twice, the first reported reinfection death, raising serious questions about how long immunity and antibodies can last. Her immune system was compromised.

- Rapid decay of Anti–SARS-CoV-2 antibodies in people with mild Covid-19 raises concern that immunity may not be long lasting in those with mild illness, who compose the majority of infections, finds new study in NEJM (21 July 2020), with implications for herd immunity and vaccine effectiveness. https://www.nejm.org/doi/full/10.1056/nejmc2025179 3 comments science
