Wastewater Surveillance: A New Frontier for Public Health CDC, June 30, 2022 ![]() ![]()
Tracking the spread of SARS-CoV-2, the virus that causes COVID-19 continues to be vital to interrupting chains of transmission, preventing new cases of illness, and saving lives. Scientists can test community wastewater samples to detect the ribonucleic acid, or “RNA,” of SARS-CoV-2. Wastewater testing is a novel approach for monitoring the virus, providing timely information about the changing prevalence of COVID-19 in different communities.

Delta reinfection risk low among unvaccinated children. Ledford Heidi et al. Nature 2022 6 ![]() ![]() ![]()
Children and adolescents who had not been vaccinated against COVID-19 mounted a long-lasting immune response to infection with the Delta variant of the coronavirus SARS-CoV-2, according to a large study of Israeli health records. But scientists warn that the findings do not mean that children should not be vaccinated against COVID-19.

Booster dose of BNT162b2 after two doses of CoronaVac improves neutralization of SARS-CoV-2 Omicron variant GRF Campos et al, Comm Medicine, June 29, 2022 ![]() ![]() ![]()
Based on viral microneutralization assays, we evaluated in 90 individuals the impact on antibody neutralization induction, against Omicron variant, by a booster dose of BNT162b2 mRNA vaccine after the CoronaVac primary vaccination scheme. Here we show that the percentage of seroconverted individuals 30 and 60 days after CoronaVac scheme was 16.6% and 10%, respectively. After booster dose administration, the seroconvertion rate increased to 76.6%. The neutralization mean titer against Omicron in the CoronaVac protocol decreased over time, but after the booster dose, the mean titer increased 43.1 times.
