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.

mRNA COVID-19 vaccine protection wanes after six months: a wide-scale study of the population of Qatar

In a paper recently uploaded to the preprint server medRxiv* by Chemaitelly et al. (August 27, 2021), the long-term effectiveness of the mRNA vaccines is analyzed amongst the Qatar population. The study observed waning protection against infection around six months post-vaccination but lasting protection from death and hospitalization.

Booster shot of Pfizer COVID-19 vaccine provides additional protection against SARS-CoV-2 infection

A team of scientists from the USA and Israel has recently highlighted the importance of a third booster dose of the Pfizer/BioNTech coronavirus disease 2019 (COVID-19) vaccine in achieving additional protection against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The study is currently available on the medRxiv* preprint server.

Do kidney transplant recipients need a third booster dose of mRNA COVID-19 vaccine?

A team of researchers in France have observed that the “standard” 2 dose regimen for mRNA COVID-19 vaccines could provide adequate protection to only a few KTRs. It has also been shown in multiple studies that a considerable population of vaccinated KTRs were easily infected with SARS-CoV-2.

Vaccinated individuals with breakthrough SARS-CoV-2 infection have much lower risk of hospitalization

A recent study conducted by a team of US-based scientists has revealed that unvaccinated individuals are 17-times more likely to be hospitalized due to severe coronavirus disease 2019 (COVID-19) compared to those vaccinated against the disease. The study is currently available on the medRxiv* preprint server.

COVID-19 vaccine elicits antibody responses in nearly 9 out of 10 people taking immunosuppressants

COVID-19 vaccination elicited antibody responses in nearly nine out of 10 people with weakened immune systems, although their responses were only about one-third as strong as those mounted by healthy people, according to a study by researchers at Washington University School of Medicine in St. Louis.

Modeling of COVID-19 seroprevalence and resurgence in Canada

Despite increased vaccine distribution and a significant decrease in the number of COVID-19 cases in Canada, the future of the pandemic is still a major concern, based on the possibility of a resurgence in the short term as well as long term and an understanding of the future of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunity. It is not clear if the Canadian population will reach herd immunity or if there is a risk of future resurgence of the virus in the Fall or Winter.
