Maternal SARS-CoV-2 vaccination in early-third trimester may optimize neonatal seroprotection

Researchers in Israel have conducted a study showing that vaccinating pregnant women against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) early on in the third trimester may maximize transplacental antibody transfer, potentially helping to prevent severe coronavirus disease 2019 (COVID-19) during infancy.

Mystery deaths of children blamed on insanitary conditions and poor resources in India

While authorities in Uttar Pradesh are narrowing down on dengue as the 'mystery disease' behind the deaths of more than 50 people, mostly children, in the last fortnight, they are not ruling out scrub typhus or other monsoon-related infections.

Will mRNA vaccine boosters be required for SARS-CoV-2 variants?

A new study shows that the highly effective mRNA Moderna vaccine designed against the original SARS-CoV-2 strain may lose some efficacy as new variants arise.

30 Aug 2021

Two mRNA vaccines are effective even without post-shot symptoms or prior SARS-CoV-2 infection

Vaccination with the two messenger RNA (mRNA) vaccines for SARS-CoV-2, the virus that causes COVID-19, yields a robust antibody response, even if a person did not develop significant symptoms following vaccination or did not have a prior SARS-CoV-2 infection.

26 Aug 2021

Analysis of antibody titer decay following vaccination or SARS-CoV-2 infection

A new study focused on the decrease in antibody titers following two doses of BNT162b2 vaccine or SARS-CoV-2 natural infection in Israel.

Study shows difference in antibody levels in response to SARS-CoV-2 infection and type of vaccination

In a recent study, researchers aimed to monitor the levels of the anti-SARS-CoV-2 spike IgG levels in populations that were subjected to routine tests.

24 Aug 2021

Expansion of seasonal betacoronavirus antibodies post-vaccination is associated with reduction in neutralization of the SARS-CoV-2 variants of concern

A new study determined the antibody response to SARS-CoV-2 and seasonal viruses induced by BNT162b2-Comirnaty vaccination in healthcare workers.
