Current pandemic COVID-19 vaccine strategies and development: a comprehensive review

The coronavirus disease-19 pandemic with the characteristics of asymptomatic condition, long incubation period and poor treatment has influenced the entire globe. Coronaviruses are important emergent pathogens, specifically, the recently emerged sever acute respiratory syndrome coronavirus 2, the causative virus of the current COVID-19 pandemic. To mitigate the virus and curtail the infection risk, vaccines are the most hopeful solution. The protein structure and genome sequence of SARS-CoV-2 were processed and provided in record time; providing feasibility to the development of COVID-19 vaccines. In an unprecedented scientific and technological effort, vaccines against SARS-CoV-2 have been developed in less than one year. This review addresses the approaches adopted for SARS-CoV-2 vaccine development and the effectiveness of the currently approved vaccines(AU)

La pandemia de COVID-19, con sus características de condición asintomática, largo periodo de incubación y escaso tratamiento, ha tenido un impacto global. Los coronavirus son importantes patógenos emergentes, específicamente, el coronavirus del síndrome respiratorio agudo severo 2 descubierto recientemente, virus causal de la actual pandemia de COVID-19. Para mitigar el virus y reducir el riesgo de infección, las vacunas son la solución más esperanzadora. La estructura de la proteína y la secuencia del genoma del SARS-CoV-2 se procesaron y proporcionaron en un tiempo récord, lo que ha permitido el desarrollo de las vacunas contra el COVID-19. En un esfuerzo científico y tecnológico sin precedentes, se han desarrollado vacunas contra el SARS-CoV-2 en menos de un año. Esta revisión aborda los enfoques adoptados para el desarrollo de la vacuna contra el SARS-CoV-2 y la eficacia de las vacunas actualmente aprobadas(AU)

Standard of Care in Clinical Research Involving Human Subjects: A Perspective from Developing World.

Abstract: Standard of care is an ordinary, reasonable formal treatment and diagnostic process that a physician should follow for his/her patient with specific disease. Standard of care followed in one country may not suit to other country; the reason may involve economic conditions, certain norms, beliefs, tradition and culture of that society. It may be considered ethical if it does not exploit human rights and poor vulnerable population, once it exploits the human rights it creates ethical dilemmas that need to be sort out to protect vulnerable population and to make the research more ethical. Patients attending medicine department of Bolan Medical Complex (BMC) Quetta, Balochistan, Pakistan were selected randomly interviewed and requested to fill the questionnaire. The ethical issues in clinical research conducted on human population have been perplexing and remains to be the same in clinical research settings. Exploitive use of research participants in resource poor developing countries has intensified the debate on the ethics of international research and led to increasing attention to exploitation of vulnerable study subjects. The issues of conducting research in developing countries will remain and need to be focused and debated where and whenever require. One has to try sincerely to sort out the ethical problems while conducting a research study, he might fail to solve all the issues but the situation may improve by the time if tried sincerely.

Issues of research ethics and clinical ethics in developing world, possible solution: a way forward.

ABSTRACT: Research plays a pivotal role in the progress of inventions in medicines and medical technology. It is noticed that researchers from developing world or multinational companies are interested to conduct their research studies in developing countries, in doing so sometimes it is noticed that rather benefiting the participants it causes significant harm to the research study participants of developing countries. Ethical lapses in research can significantly harm human subjects. In research ethics the basic aim of ethics is distinguishing between right and wrong, to recognize the wrong doings and try to avoid them from harming research subjects in any research study whether that is done in developing country or developed country. It must follow the principle of non malefiecence or do no harm.
