Summary: The study found that Malawi experienced two waves of SARS-CoV-2 epidemic, with widespread exposure and high antibody detection rates in both urban and rural areas. The first wave sera showed higher neutralization activity against the original variant, while the second wave sera exhibited higher neutralization activity against the Beta variant. Blantyre and Mzuzu also showed signs of a third pandemic wave.

Summary: This study investigated whether antibodies against SARS-CoV-2 were associated with a decreased risk of symptomatic and asymptomatic reinfection. It found that individuals with a previous history of SARS-CoV-2 infection had an 84% lower risk of reinfection, with a median protective effect lasting for 7 months following primary infection.

Summary: Virus-specific antibody levels after a single dose of the BNT162b2 vaccine in individuals previously infected with SARS-CoV-2 are similar to levels after two doses of the vaccine in infection-naive individuals. Post-vaccine symptoms were more prominent for those with prior infection after the first dose, but symptomology was similar between groups after the second dose.

Summary: The ChAdOx1 nCoV-19 vaccine did not provide significant protection against mild-to-moderate Covid-19 caused by the B.1.351 variant, with an efficacy of 10.4%. The incidence of serious adverse events was balanced between the vaccine and placebo groups.

Summary: The NVX-CoV2373 vaccine showed efficacy in preventing Covid-19, with higher vaccine efficacy observed among HIV-negative participants. Most infections were caused by the B.1.351 variant.

Summary: The study found that vaccination of both previously infected individuals and those who were not infected resulted in increased neutralizing antibody titers, with previously infected individuals showing a greater boost in neutralizing titers. Vaccination of naive individuals also elicited cross-neutralizing responses, but at lower titers.

Summary: This study characterized clinical and immunological responses of patients with confirmed and suspected COVID-19 in a hospital in Malawi, revealing that suspected patients had inflammatory profiles similar to confirmed cases, potentially making them a target population for COVID-19 treatment strategies.

Summary: The study shows that reinfection is rare in Qatar's young and international population, with natural infection providing strong protection against reinfection with an estimated efficacy of around 95% for at least seven months. Reinfections are often less severe than primary infections.

Summary: The prevalence of anti-SARS-CoV-2 immunoglobulin G among blood donors in Kenya from April to June 2020 was 4.3%, with the highest rates in urban counties like Mombasa, Nairobi, and Kisumu. This suggests that SARS-CoV-2 exposure is more widespread than case-based surveillance indicates.
