New research highlights the long-lasting effectiveness of mRNA COVID-19 vaccines, showing sustained B-cell and antibody responses in health care workers over 3 years.

These results suggest that individuals who are immunocompromised with type 2 diabetes (T2D) may need multiple doses of a pneumococcal conjugate vaccine (PCV) to sustain their protection.

The recommendations are not considered to be final until they are published in the Morbidity and Mortality Weekly Report.

Patients who received a pneumococcal 13-valent conjugate vaccination had slightly lower incidence of severe COVID-19 outcomes, but the directions of these associations were mixed.

The findings suggest a positive impact of RSV vaccination on RSV-associated hospital admission, emphasizing the importance of protection in this population.

In a survey among community pharmacists in South Carolina, many pharmacists were unable to correctly identify proper pneumococcal vaccination guideline, raising concerns.

Monetary incentives to receive a COVID-19 vaccine at a public vaccination event may have inadvertently turned away others from receiving a booster, emphasizing the importance of recognizing spillover in trials addressing vaccine hesitancy.

A significant portion of unvaccinated individuals were open to future vaccination.
