Abstract:
A COVID-19 pandemic has erupted around the world. World Health Organization (WHO) and allies are racing to create and deploy safe and effective vaccines as they work together to monitor the pandemic, advise on crucial measures, and distribute essential medical resources to those in need. Vaccines save millions of lives, by training the body's natural defenses, the immune system, to identify and combat the viruses and bacteria they are intended to combat. This review article presents the status of COVID-19 vaccines evaluated by the WHO Emergency Use Listing (EUL) assessment process and those liberated as well. Data was obtained from the WHO, Gavi – The Vaccine Alliance from Bill & Melinda Gates Foundation, Oxford Vaccine Group, Serum Institute of India, AstraZeneca, European Medicines Agency EMA among others. As can be seen, there is still no totally effective vaccine, and many clinical trials are still needed, and even immunized citizens are still at risk of recontagion. Virus mutation is a recurring problem and different vaccine production methodologies are still being studied.
