Every year millions of people die due to transmission of infectious diseases like HIV, malaria, tuberculosis, tropical diseases, viral hepatitis, and several others. Most of the people infected by such diseases are poor. Even there are certain diseases which can be prevented by vaccines but due to negligence and lack of proper diagnosis diseases like measles continue to take 140,000 lives almost every year. Another disease is dengue that sickens 50–100 million people every year according to WHO. Polio is a rearising concern, which once was eradicated but its cases are still on a rise since 2014. For some viral diseases, vaccines and antiviral drugs have allowed us to keep infections from spreading widely, and have helped sick people recover. In recent decades, several viruses have jumped from animals to humans and triggered sizable outbreaks, claiming thousands of lives. Some of such diseases are Hantavirus was first found in the United States in 1993, Marburg virus in 1967 in Germany which was caused due to import of infected monkeys from Uganda, Ebola outbreak in 2014 in West Africa that killed 90% of the infected people and the most recent one is SARS-CoV-2 also called COVID-19 which was first identified in December 2019 in a Chinese city in Wuhan.

In order to illustrate how an RCT is performed, we will use Salk’s polio vaccine example, which at the time was the largest public health experiment ever performed. As a background, polio is an infectious disease that can invade the brain and spinal cord, leading to paralysis. There is no cure for polio. The polio epidemic hit the United States in the first half of the nineteenth century and was responsible for 6% of deaths in U.S. children aged 5 to 9, peaking in 1953. In 1954, American physician Jonas Salk developed a vaccine that he believed could be effective as initial research in animals looked promising. The basic steps of the experiment were as follows:

This call for need of vaccination has shown to be effective in controlling outbreaks such as polio. Vaccines work by preparing host body’s natural defences (immune system) to identify and counter-targeted viruses and bacteria. As of mid-February 2021, there are at least seven developed vaccines used globally. Concurrently, there are over 200 additional COVID-19 vaccines candidate in development and undergoing clinical trials. However, COVAX is the most popular one, which is endorsed by WHO (WHO COVID-19 Vaccines, 2021). Prior to the launching of COVAX, Russia is the first country to approve COVID-19 vaccines in August, 2020, which is developed by Gamaleya National Center of Epidemiology and Microbiology (Moscow, Russia). The vaccine has faced many criticisms from scientist all over the world due to its premature approval (Burki, 2020).
