Study assesses COVID-19 policy differences between GOP- and Democrat-led states

The per-capita rates of new COVID-19 cases and COVID-19 deaths were higher in states with Democrat governors in the first months of the pandemic last year, but became much higher in states with Republican governors by mid-summer and through 2020, possibly reflecting COVID-19 policy differences between GOP- and Democrat-led states, according to a study led by researchers at the Johns Hopkins Bloomberg School of Public Health and the Medical University of South Carolina.

Danish study on the efficacy of Pfizer/BioNTech SARS-CoV-2 vaccine after first and second dose

As the coronavirus disease 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues, many countries have rolled out vaccines against the virus. In an encouraging preprint research paper posted to the medRxiv* server, scientists report on the vaccine efficacy in the Danish vaccination program.

South African SARS-CoV-2 variant most problematic for BNT-162b2 vaccine

Researchers from Germany and the US investigated the efficacy of neutralizing antibodies against newer variants using serum and saliva samples obtained from groups of infected, vaccinated (with Pfizer BNT-162b2), and uninfected individuals. The researchers started this study to uncover vaccine-induced immune response and show the efficiency of antibody binding and neutralization in SARS-CoV-2 variants.

Study confirms COVID-19 vaccine rollout decreasing disease incidence across USA

By comparing vaccination rates in 580 counties across the United States with the corresponding coronavirus disease (COVID-19) incidence rates, a recent study currently available on the medRxiv preprint server finds that cumulative county-level vaccination rates are significantly associated with a concomitant fall in the incidence of COVID-19.

Genome-wide covariation analysis sheds light on the evolution of SARS-CoV-2

Researchers in the United States have computed genome-wide covariation within severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to investigate interactions that could be of considerable importance in the prevention, diagnosis, and treatment of coronavirus disease 2019 (COVID-19).

Researchers study prevalence of SARS-CoV-2 UK variant at University of Texas

Researchers at the University of Texas at Austin and Santa Fe Institute in the US used quantitative polymerase chain reaction (PCR) data from a surveillance testing program on a large university campus to estimate how fast the new variant spreads. The team used the data to provide local situational information on the COVID-19 pandemic.
