A Yale-designed 'Prime and Spike' nasal vaccine approach can help combat COVID-19 by bolstering immune responses in the respiratory system. The strategy, which involves a combination of a prime vaccination and a spike protein booster administered directly into the nostril, has been shown to reduce viral shedding and transmission.
A recent study by West Virginia University sociologists found that individuals with paranormal beliefs are more likely to be hesitant about vaccination. These beliefs, which include astrology and spirits, lead to a lack of confidence in science and vaccines, including the COVID-19 shot.
A review of COVID-19 and other adult vaccination efforts found that cash transfers and lottery programs had limited outcomes in increasing vaccination rates, with some studies showing a slight over 2% increase in coverage. Non-cash incentives also showed no significant impact on vaccination uptake.
