Adverse Events and Immunogenicity of mRNA-Based COVID-19 Vaccine among Healthcare Workers: A Single-Centre Experience

Decline of Anti-SARS-CoV-2 IgG Antibody Levels 6 Months after Complete BNT162b2 Vaccination in Healthcare Workers to Levels Observed Following the First Vaccine Dose

Oktavija Dakovic Rode et al.

Summary: Research on post-vaccination antibody dynamics is crucial in estimating COVID-19 vaccine efficacy. This study found that antibody levels significantly increased one month after vaccination and exponentially decreased three and six months after complete vaccination. Participants with a prior history of COVID-19 had higher antibody levels, particularly after the first dose. Six months after vaccination, antibody levels were comparable to those seen in COVID-19-naive participants after the first vaccine dose.

SARS-CoV-2 Spike Protein Elicits Cell Signaling in Human Host Cells: Implications for Possible Consequences of COVID-19 Vaccines

Yuichiro J. Suzuki et al.

Summary: This article highlights the potential impact of the spike protein from COVID-19 vaccines on human host cells and emphasizes the need for careful monitoring of the long-term consequences. Further research on the effects of the SARS-CoV-2 spike protein on human cells and appropriate animal models is recommended.

Effects of Natural Ventilation and Saliva Standard Ejectors during the COVID-19 Pandemic: A Quantitative Analysis of Aerosol Produced during Dental Procedures

Imena Rexhepi et al.

Summary: In dental procedures, using standard saliva ejectors can reduce the total amount of released PM10, thus decreasing the risk of exposure to SARS-CoV-2 in high-risk environments. On the other hand, natural ventilation may lead to increased particulate matter release, especially during scaling procedures.
