A review of approved COVID-19 vaccines

Abstract

In the past one and half year elapsed since the identification of the SARS-CoV-2 virus and its genome, an extraordinary effort by the scientific community has led to the development of many vaccine projects. More than ten vaccine candidates throughout the world have been granted approval for emergency use. Existing data suggest that these vaccines have the potential to protect individuals and curb the spread of COVID-19 pandemic. However, long term side-effects and certain unresolved issues associated with vaccine use need to be assessed as the time passes. This study reviews the most recent data of 12 vaccines which have been approved for use and presents information on their doses, composition, mechanism of action, side effects, etc.

COVID-19 vaccination side effects among the child age group: a large cross-sectional online based survey in Saudi Arabia

“…Since COVID-19 is declared as a pandemic, vaccination brought hope to control this condition. There are different COVID-19 vaccines approved by WHO, such as The Pfizer/BioNTech vaccine and AstraZeneca/AZD1222 vaccines [ 7 , 8 ]. Vaccinations can provide excellent protection from serious illness, hospitalization, and death.…”

A comprehensive review of the use of Sodium Chloride (NaCl) in the development of the COVID-19 vaccine and medical applications

“…The COVID-19 vaccine provides acquired immunity against the virus that causes coronavirus SARS-CoV-2 disease (Jamkhande et al 2021). Numerous worldwide immunization campaigns were launched after the new pathogen was discovered and sequenced.…”

“…A recent study found that the COVID-19 pandemic vaccines effectively protect individuals and limit their spread. Long-term consequences and unanswered questions about vaccination use, on the other hand, need to be assessed over time (Jamkhande et al 2021). Table 1 included the application of sodium chloride (NaCl) in medical as well as in the treatment of SARS-CoV-2 and the approved vaccines.…”

Evaluation of serum soluble HLA-G levels post-recovery from COVID-19 and post-vaccination (Sinopharm and Pfizer-BioNTech)

“…Since there is no effective treatment for COVID-19, vaccination is one of the most effective strategies that may limit the spread of the disease in humans. More than ten candidate vaccines worldwide have received approval for emergency use, including Pfizer-BioNTech (a messenger RNA [mRNA] vaccine) and Sinopharm (an inactivated whole-virus vaccine) [13] . Both vaccines are approved for use in Iraq and are given in two doses, 21 days apart.…”
