COVID-19 Vaccine Booster Strategies in Light of Emerging Viral Variants: Frequency, Timing, and Target Groups

It is found that the more frequently variants emerge, the less the effect boosters will have, regardless of whether administered annually or biannually, and delivering well-timed annual COVID-19 vaccine boosters to all those eligible, prioritising those most vulnerable, can reduce infections and hospital admissions.

Evaluation of Effectiveness of Global COVID-19 Vaccination Campaign

To model estimated deaths averted by COVID-19 vaccines, we used state-of-the-art mathematical modeling, likelihood-based inference, and reported COVID-19 death and vaccination data. We estimated that

Despite its ‘silent killer’ sobriquet, the global efforts to tackle hypertension has been tepid at best. Its insidious impact on humanity over the last century is expected to last far into the future

COVID-19: vaccines, efficacy and effects on variants

Three leading strategies of vaccine development against coronavirus disease 2019 (COVID- 19): mRNA vaccines, adenoviral vector vaccines and recombinant nanoparticles are reviewed and the evidence for the effectiveness of the vaccines against those five VoC is explored.

STUDY OF ACCEPTANCE OF COVID-19 VACCINE AND ITS ASSOCIATED FACTORS AMONG POST GRADUATE STUDENTS IN A MEDICAL COLLEGE

It can be concluded that no major side effects were associated with this vaccine and it was found that only about 87 (43.5%) Postgraduate students got vaccinated.

Vaccination and three non-pharmaceutical interventions determine the dynamics of COVID-19 in the US

A new analytical framework is developed that treats COVID-19 as a feedback control system with the NPIs and vaccination as the controllers and a computational model that maps human social behaviors into input signals to effectively predict the epidemic spreading in 381 Metropolitan statistical areas (MSAs) in the US.

Race-Specific, State-Specific COVID-19 Vaccination Rates Adjusted for Age

This work provides the first age-standardized race/ethnicity-specific, state-specific vaccination rates for the United States, encompassing all states reporting race/ ethnicity-specific vaccinations, and finds that racial/ethnic group vaccination rates are associated with state politics.
