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.

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.

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.

Bhutan starts immunizing children in the 12 to 19 age group against COVID-19

Bhutan is following up on its success in vaccinating 90 per cent of its adult population against COVID-19 by embarking on a plan to immunize children in the 12 to 19 age group.

Study examines impact of COVID pandemic on birth outcomes in Wales

Researchers in the UK have looked at the impact of the COVID-19 (coronavirus disease 2019) pandemic on the population birth outcomes in 2020, detailing the experiences of the expectant mothers from immunization rates for babies to self-reported levels of stress and anxiety in the mothers, compared to pre-COVID years.

COVID-19 hospitalizations 29 times more likely in unvaccinated individuals, CDC study suggests

Getting inoculated against SARS-CoV-2 protects against getting severe COVID-19 or being hospitalized. In a new study by the U.S. Centers for Disease Control and Prevention (CDC), scientists noted that unvaccinated individuals are 29 times more likely to be hospitalized due to COVID-19 than those who were vaccinated.

COVID booster shots might be needed in subgroup of HIV-positive individuals

The coronavirus disease (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has evolved into a global pandemic destroying lives and economies. COVID-19 is not curable, so vaccines are the only safeguard during this pandemic.
