The protection of health care workers from nosocomial infection is a paramount consideration in the current pandemic involving severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Not only is prevention of viral transmission the most effective means to lessen the public health impact of coronavirus disease 2019 (COVID-19), but also both quarantine and illness – that disproportionately affect health care workers – have devastating effects on the ability of hospitals to adequately care for increased patient loads.

The recent pandemic of SARS-CoV-2 has emerged as a health emergency to develop effective therapeutic strategies for restricting deadly disease, COVID-19. SARS-CoV-2 infects cells by the endocytosis process via receptor-mediated binding and priming by cellular proteases.

A 22-day-old male neonate was admitted to the neonatal intensive care unit (NICU) with complaints of abnormal movements, fever, breath holding spells, refusal and bluish discoloration of skin. He was born at term with a birthweight of 2·72 kg to a mother with a history of positive polymerase chain reaction for SARS-Coronavirus-2 (SARS-COV-2) virus (RT-PCR-positive), asymptomatic 2019 novel coronavirus disease (COVID-19) at 32-33 weeks gestation, which did not require any supportive measures.

The ongoing global Coronavirus Disease 2019 (COVID19) pandemic has enormous social and economic impact. COVID19 is caused by the Coronavirus Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) and is characterized by a high transmission rate and increased mortality from acute respiratory distress syndrome compared to other viruses.

A recent article published by Abbas et al. in the Journal of Biomedicine and Pharmacotherapy systematically revealed about the vaccines developed against the recent pandemic agents SARS-CoV-2 and its variants [1]. The authors insightfully provided an overview on the distinct features of the SARS-CoV-2 new variants, the associated mortality rate, hospitalization, re-infection and finally the efficacy of different vaccines.
