Beliefs and Barriers to COVID-19 Vaccine Acceptance in Three Countries with Different Human Development Index (HDI) Scores: A Comparative Study.

Background: As vaccination is a cornerstone strategy to prevent the spread of COVID-19, this study assessed and compared beliefs about and barriers to COVID-19 vaccination among the population of three countries with different Human Development Index (HDI) scores: Saudi Arabia (very high), India (medium), and Sudan (low).

Methods: A web-based, self-administered structured questionnaire was employed to collect data from the three countries. The questionnaire contained three sections that measured sociodemographic characteristics, participants' beliefs about and attitudes toward COVID-19 vaccines, barriers to receiving COVID-19 vaccines, and scenarios in which there is a possibility to take a COVID-19 vaccine.

Congenital chylothorax--successful management with chemical pleurodesis.

We report a case of congenital bilateral chylothorax presenting as non immune hydrops and managed successfully with chemical pleurodesis.
