Fluid collection surrounding breast implants, called seroma, is a frequent issue that has diverse etiologies. We describe a 48-year-old woman with an acute onset of bilateral breast swelling occurring 5 years after aesthetic surgery and 10 days after a second SARS-CoV-2 mRNA vaccine dose. At breast ultrasound, we found an abundant bilateral peri-implant seroma. Our patient noticed symptom improvement 48 h after nonsteroidal anti-inflammatory drug treatment, complete disappearance of symptoms after 10 days with seroma disappearance documented by ultrasound. We hypothesized a breast implant seroma as post-SARS-CoV-2 mRNA vaccine side effect, as different other diagnosis had been excluded.

Background The safety and adverse effects (AEs) associated with approved COVID-19 vaccines in individuals with multiple sclerosis (MS) require further examination, particularly as there is limited information available for MS patients in Saudi Arabia. This study sought to investigate the reported AEs of COVID-19 vaccines among MS patients admitted to a major rehabilitation center in Saudi Arabia. Methods A cross-sectional analysis was conducted from January 2023 to March 2024 at Sultan Bin Abdulaziz Humanitarian City (SBAHC) in Riyadh.

A total of 5011 adult volunteers attending vaccination centers in different regions of Colombia were enrolled in a 1-year prospective observational cohort study to evaluate the immunogenicity and effectiveness of SARS-CoV-2-based vaccines as part of a National Vaccine Program established to contain the COVID-19 pandemic. Following informed consent, 5,011 participants underwent a sociodemographic survey and PCR testing to assess SARS-CoV-2 infection. Blood samples were collected, and serum fractions were obtained from a participant subsample (n = 3441) at six-time points to assess virus-specific IgG responses to the Spike protein, its Receptor Binding Domain, and the Nucleoprotein by ELISA.

Circular RNA (circRNA) has gained attention as a promising platform for mRNA vaccines due to its stability, sustained protein expression, and intrinsic immunostimulatory properties. This study aimed to design and optimize a circRNA cancer vaccine platform by screening for efficient internal ribosome entry sites (IRES) and enhancing circRNA translation efficiency for improved cancer immunotherapy. We screened 29 IRES elements to identify the most efficient one for immune cell translation, ultimately discovering the A (EV-A) IRES.

The waning immunity following the COVID-19 vaccination become a significant concern and the immunological dynamics of vaccine-induced antibodies after vaccination need to be explored. The aim of this study was to compare anti-SARS-CoV-2 receptor-binding domain (RBD) antibody levels before and after a booster dose with heterologous COVID-19 vaccine and to identify factors influencing the levels after receiving the booster dose. A cross-sectional study was conducted in which individuals who received primary doses of CoronaVac and a booster dose with an mRNA-based vaccine were recruited using a purposive sampling technique.
