Summary: This study aimed to investigate the association between social capital and COVID-19 vaccination. The results showed that individuals with social capital were more likely to receive COVID-19 vaccination compared to those without, indicating that social capital may be a factor in reducing vaccine hesitancy.

Summary: This study evaluated the effectiveness of two doses of BNT162b2 or mRNA-1273 vaccines against the Delta variant in the Japanese population from June to September 2021. The VE was found to be 92% in June-July and 79% in August-September, and adjusted VE for homestay, hotel-based isolation, and hospitalization was 78%, 77%, and 97%, respectively. Despite a slight decline, VE against hospitalization remained strong for about 3 months after the second dose, indicating the need for longer-term monitoring of VE against new variants in vaccination policymaking.

Summary: This study aimed to investigate the effectiveness of COVID-19 mRNA boosters in individuals with different immune histories and clinical vulnerability profiles. The data showed that the booster vaccine provided 26.2% effectiveness against infection and 75.1% effectiveness against severe, critical, or fatal COVID-19 during a 1-year follow-up period. The effectiveness was particularly significant in individuals who were clinically vulnerable to severe COVID-19.

Summary: The study aims to determine the effectiveness of COVID-19 vaccines in the healthcare system of the U.S. Department of Veterans Affairs. Research on over 2 million individuals who received the Moderna or Pfizer-BioNTech COVID19 vaccines showed a vaccine effectiveness of 69% against SARS-CoV-2 infection and 86% against SARS-CoV-2-related death.

Summary: This study compared cfRNA profiles between COVID-19 patients and healthy donors, and found 380 up-regulated cfRNA molecules in all COVID-19 patients. Several potential biomarkers were identified. Antiviral and neutrophil activation-related genes showed decreased expression levels during treatment, which is consistent with enhanced inflammatory response in COVID-19 patients. Differential expression of noncoding RNAs and changes in tRNA pools related to SARS-CoV-2 replication were also observed. Additionally, pneumonia-related microorganisms were detected in the plasma of COVID-19 patients.

Summary: This study investigated the duration and effectiveness of immunity among healthcare workers in the United Kingdom. It found that two doses of the BNT162b2 vaccine provided high short-term protection against SARS-CoV-2 infection, but this protection significantly decreased after six months. However, infection-acquired immunity boosted by vaccination remained high, even more than one year after infection.

Summary: This study investigated the acceptance and hesitancy towards the COVID-19 vaccine in Japan, finding that 62.1% of participants were willing to get vaccinated. The research also revealed that vaccine acceptance was lower among women, adults aged 20-49 years, and those with a low-income level. Psychological factors, such as the perceived effectiveness of the vaccine and willingness to protect others, were identified as important factors associated with vaccine acceptance.

Summary: This study examines the effectiveness of COVID-19 vaccines against COVID-19 and all-cause mortality during different periods in 2022 using data from Australia. The findings show that the effectiveness of the vaccines in preventing COVID-19 mortality decreases over time since the last dose, emphasizing the importance of administering booster doses to those at highest risk.

Summary: The study in Scotland found that the first doses of the BNT162b2 mRNA and ChAdOx1 vaccines were associated with substantial reductions in the risk of COVID-19 hospital admission, with vaccine effectiveness ranging from 88% to 91% at 28-34 days post-vaccination.

Summary: While the majority of COVID-19 vaccine breakthrough cases in England were mild, some differences in rates of breakthrough cases have been identified in several clinical groups. Further analysis is needed to assess vaccine waning and rates of breakthrough COVID-19 between different variants in order to identify individuals at higher risk.

Summary: Evidence from a cohort study in Norway indicates that a fourth dose of mRNA vaccine provides increased protection against severe outcomes of COVID-19, particularly among individuals aged 75 years and older. Bivalent vaccines show better protection compared to monovalent vaccines, but the protective effect diminishes over time.

Summary: A survey in Japan revealed that healthcare workers, especially nurses, had lower acceptance rates of the COVID-19 vaccine compared to the general population. Women and young adults were more likely to be hesitant about vaccination, while smokers were more likely to accept it. Nurses showed a higher hesitancy rate compared to the general population.

Summary: A retrospective cohort study in Ontario, Canada found that three doses of mRNA COVID-19 vaccine were associated with a lower risk of SARS-CoV-2 infection and severe outcomes compared to two doses in the hemodialysis population. Additionally, prior infection was found to be associated with a reduced risk of reinfection.

Summary: The efficacy of COVID-19 vaccination in patients with hematological malignancies appears limited and varies across different diseases and treatments. Clinical outcomes are rarely reported, with low rates of infection, symptomatic disease, hospital admission, and death. Seroconversion rates show heterogeneity, with lower response rates in patients receiving B-cell depleting treatment. Vaccine-induced T-cell response and adverse events are rarely reported as well.
