Study suggests Covid and flu shots given together may boost antibody response

Covid and flu shots can be safely given at the same time, and according to a small new study, doing so may even confer benefits. Findings presented Monday at the Vaccines Summit Boston, an annual scientific conference, suggest that giving Covid and flu shots together could produce a stronger antibody response against the coronavirus than administering the vaccines separately. The study measured the antibody levels of 42 health care workers in Massachusetts who were vaccinated last fall.

Twelve of the participants received a bivalent Covid booster and seasonal influenza shot on the same day. Another 30 received the shots on different days within the span of a month. Three to four weeks after people got their Covid boosters, those who had received the flu shot at the same time had higher levels of IgG1, an antibody involved in the body's front-line defense against Covid. The results held true six months later, suggesting that co-administering the vaccines could improve long-term protectio

Genome-wide association study identifies bacterial SNPs associated with host body mass indexA new study has identified bacterial single-nucleotide polymorphisms (SNPs) associated with host body mass index (BMI) through a metagenome-wide association study (MWAS). The study discovered 1,358 statistically significant associations between bacterial SNPs and BMI, with 40 independent associations. These associations were not explained by diet, medications, or physical exercise, and 17 of them replicated in a separate cohort. The study also revealed BMI-associated SNPs in 27 bacterial species, 12 of which were not detected by standard analysis methods.
