The announcement by Russia about the approval of a COVID-19 vaccine has set the alarm bells ringing around the world. Russia has approved the vaccine while WHO’s official database shows that this vaccine is only at Phase-1 trials. As per WHO’s database, a total of 29 vaccine candidates are at different stages of clinical trials while 6 of them are at Phase-3 clinical trials. Across the globe, scientists and researchers are racing against time to find a vaccine for COVID-19 caused by the SARS-CoV-2 virus. As is evident from the data on number of cases across the world, COVID-19 is highly contagious and till a vaccine is available for large scale public use, the only way that one can stay safe is through social distancing, wearing masks, and personal hygiene. Since vaccine is essential to make a large section of the population immune to the infection, the entire world is waiting for a vaccine with bated breath. Vladimir Putin announced the world’s first vaccine approved in Russia The Russian President Vladimir Putin made an announcement on 11 August 2020 that the world’s first COVID-19 vaccine, named Sputnik V has been approved by Russia and that one of his daughters got vaccinated. The Government of Russia tweeted on the same day saying that- ‘the Russian Healthcare Ministry had given regulatory approval to the world’s first coronavirus vaccine. Its effectiveness and safety were confirmed in clinical trials.’ However, concerns have been raised on its ‘effectiveness’ and ‘safety’ since the vaccine has not completed large-scale clinical trials. Large-scale clinical trials on thousands of persons are necessary in order to study the side effects of a vaccine which may not be evident in smaller trials.

Meanwhile, as per the World Health Organization’s list of vaccine candidates and status of trials, as on 13 August 2020, the Adeno based vaccine was at the Phase-1 of clinical trials. Three phases of clinical trials need to be passed by vaccine candidates before approval Phase-1 of clinical trials involves the testing of the vaccine among a small number of healthy adults, say around 20. During this phase, the properties of the vaccine and its tolerability are tested, and if found appropriate, its clinical laboratory and pharmacological parameters are also recorded. In phase-2, a target population based on certain parameters like age, and physical health is selected and preliminary information on vaccines ability to produce desired effect among the persons and general safety is recorded. The last stage, phase-3, is when thousands of persons are tested. A large number of people are given the vaccine to assess protective efficacy and safety on a larger scale.

Out of these, the following six (6) candidates in phase-3 trials There are two other candidates in phase-2 from China – CanSino Biological Inc. – Beijing Institute of Biotechnology and Anhui Zhifei Longcom Biopharmaceutical/Institute of Microbiology, Chinese Academy of Sciences. Of the ten candidates in phase-1/2 trials, there is one candidate each from China, Japan, South Korea, and Belgium. In addition to two US based candidates in this stage, vaccine developed by Inovio Pharmaceuticals in collaboration with UNDP’s International Vaccine Institute also falls in phase 1/2 of trials. Bharat Biotech and Cadilla Healthcare Ltd, are two Indian candidates in phase 1/2 of trials. Bharath Biotech has developed Covaxin- which is India’s first indigenous COVID-19 vaccine in collaboration with Indian Council of Medical Research and National Institute of Virology. Zydus Cadilla’s vaccine is named ZyCoV-D. There are 138 vaccine candidates in the pre-clinical stage The pre-clinical stage of testing is when the vaccine is tested on animals. Currently, there are 138 vaccine candidates at this stage. Mynvax, Indian Immunologicals Limited (in collaboration with Griffith University in Australia), Cadilla Healthcare Ltd.’s measles vector vaccine, are few other candidates from India which are in the pre-clinical trial phase.
