Article Abstract
In order to curb the transmission of SARS-CoV-2, nation-wide travel restrictions at different levels were implemented in different countries. Country-specific mutational profile may exist and have an impact on vaccine efficacy. We identified nonsynonymous mutations in approximately 215,000 SARS-CoV-2 sequences during the 1st year of the pandemic in 35 countries. Mutational profiles on a bimonthly basis were traced over time. We also examined the mutations that overlapped with the spike protein vaccine epitopes. Several new mutations emerged over time and were dominating in specific countries. Many nonsynonymous mutations were within multiple spike protein epitopes that might impact the vaccine efficacy. Our study advocates requirement of active monitoring of country-specific mutations and vaccine efficacies in respective countries.

Background: All three dengue vaccines that have completed phase 3 clinical trials have shown greater efficacy in dengue-seropositive compared to dengue-seronegative individuals. This includes the live-attenuated tetravalent dengue vaccine TAK-003, where immunogenicity in baseline seronegative individuals remains lower after two doses, despite seroconversion after the first dose, compared to baseline seropositive individuals after one dose.
Methods: A whole-genome microarray was used to analyze the host response to TAK-003.

Objective: Two vaccines against herpes zoster (HZ) are currently authorized for use in China: the adjuvanted recombinant zoster vaccine (RZV) and live-attenuated Zoster Vaccine Live (ZVL). The significant disparities in prices and efficacy between the two vaccines necessitate an evaluation of their relative value in order to make an informed choice. This study aimed to evaluate the comparative cost effectiveness of RZV, ZVL, and no vaccination for older adults at different ages from the societal perspective.

As family communication is significantly related to individuals' health decision-making, it is crucial to tap into the power of this relationship for public health initiatives. The COVID-19 pandemic provided a ripe context in which to explore whether vaccination messaging could be tailored in such a way as to target specific family communication climates to encourage vaccine promotion among family members. Specifically, our study ( = 1,276) designed pro-vaccination messaging tailored based on two types of family communication styles.

Since its discovery, the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19), has become the epicenter of public health concern. This was mainly attributed to the complexity of COVID-19 that resulted in variable disease progression with some developing asymptomatic infections, some suffering mild to moderate infections that resolved without the need for hospitalizations, and a few infected persons developing severe infections that required intensive care unit (ICU) admission and mechanical ventilation. The COVID-19 pandemic spread globally, affecting billions of people and killing millions.
