TL;DR: VE after receipt of a third dose was higher than that after a second dose; however, VE waned with increasing time since vaccination, and VE was generally higher for protection against hospitalizations than against ED/UC visits.

TL;DR: The highest estimates of VE against COVID-19-associated ED and UC encounters or hospitalizations during both Delta- and Omicron-predominant periods were among adults who received a third dose of mRNA vaccine, and all unvaccinated persons should get vaccinated as soon as possible.

TL;DR: VE against laboratory-confirmed COVID-19-associated hospitalization among children aged 5-11 years was 74% 14-67 days after dose 2, with wide CIs that included zero, and in adolescents aged 16-17 years, VE during the Omicron predominant period increased to 81% ≥7 days after a third booster dose.

TL;DR: Estimates of COVID-19 vaccine effectiveness (VE) can be reduced by newly emerging variants or sublineages that evade vaccine-induced immunity, protection from previous SARS-CoV-2 infection in unvaccinated persons (2), or increasing time since vaccination (3).
