Are you coughing, hacking or feeling feverish? It may not be just a summer cold; you might want to consider taking a Covid test. Although the autumn respiratory illness season hasn’t kicked off, and flu and RSV activity remain low, there’s a growing summer wave of Covid-19. (Christensen, 8/20)

The team compared antibody patterns recorded before and after COVID-19 vaccination. They discovered that elevated levels of several preexisting antibodies were associated with stronger responses to the vaccine, including common microbes like Staphylococcus aureus, respiratory syncytial virus (RSV), and human respirovirus 3. The scientists suggest these are “sentinel” antibodies because they are not necessarily helping the body attack the vaccine’s intended target. Instead, they may serve as signals of how prepared the antibody-producing portion of the immune system is to spring into action. (Edwards, 8/20)

Two Indigenous groups in Bolivian Amazon had the lowest COVID-19 death rates ever reported in the height of the pandemic—less than one-tenth of 1%—despite high rates of infection and severe disease—a finding that researchers say has implications for disease-mitigation efforts in future pandemics. For the study, published in Social Science & Medicine, a team led by researchers from the Universita di Corsica in France interviewed and took blood samples from members of the Tsimane and Moseten communities aged 17 years and older in July and December 2020 and March through May 2021.

Evelyn Griffin had led a life out of the spotlight until she testified at the Louisiana Statehouse five years ago and experienced what she called her “great awakening.” The state health department wanted to add covid vaccines to the school immunization schedule, a move no state has ever implemented. Robert F. Kennedy Jr., then known as a leading vaccine skeptic, had already claimed the covid shot was “the deadliest vaccine ever made” during a poster board presentation at the legislative hearing.

Each measles case in the 2025 US outbreak—the largest since the disease was eliminated from the country in 2000—cost $43,200, rising to $58,600 when including the public health response, Johns Hopkins researchers estimate in Vaccine. (Van Beusekom, 8/20)

The company’s fortunes cratered as demand for Covid-19 vaccines plummeted. But it was busy working on something else. (Robbins, 8/20)
