Latest developments on Coronavirus Vaccines

There currently are over 100 vaccines at various stages of development worldwide, including in India, Britain, China, the US, Russia and Israel.

Latest developments on Coronavirus Vaccines

The total number of coronavirus cases across the world has crossed the 11-million mark and the death toll has gone past 540,000. Coronavirus cases have only been on an upswing since it has taken the world by storm and so is the urgency of the vaccine to somehow tame this deadly virus.

The total number of coronavirus cases across the world has crossed the 11-million mark and the death toll has gone past 540,000. Coronavirus cases have only been on an upswing since it has taken the world by storm and so is the urgency of the vaccine to somehow tame this deadly virus.

Below is the status report of coronavirus candidate vaccines:-

India coronavirus vaccine status:

India’s Bharat Biotech International Ltd. has reportedly developed a candidate vaccine named Covaxin for coronavirus. The vaccine has cleared clinical trials and will begin human trials from July 7. The Indian Council for Medical Research (ICMR) has set the August 15 deadline for the launch of Covaxin. Besides this, there are 29 other coronavirus vaccines that are in different stages of development.

The Indian Academy of Sciences, a Bengaluru-based body of scientists, has said the Indian Council for Medical Research’s (ICMR) target to launch a Coronavirus vaccine by August 15 is “unfeasible” and “unrealistic”.

UK coronavirus candidate vaccine status:

Britain is close to agreeing a 500 million pound ($624 million) supply deal with Sanofi and GlaxoSmithKline for 60 million doses of their potential Covid-19 vaccine, the Sunday Times reported. The newspaper said that Britain was considering taking an option to buy the vaccine should it work in human trials, which are due to begin in September.

China’s Sinovac Biotech is starting Phase III trials of its potential Coronavirus vaccine in Brazil, becoming one of three companies to move into the late stages in the race to develop an inoculation against the disease.

It follows a fast-track approval for the trials by Brazilian regulators last week.

Sinovac said the study, which will be done in partnership with Brazilian vaccine producer the Instituto Butantan, would recruit nearly 9,000 healthcare professionals working in Covid-19 specialised facilities and start this month. Sinovac initiated the development of the vaccine candidate in late January.

Moderna coronavirus candidate vaccine status:

 Named MRNA-1273, US pharma giant Moderna has also developed a candidate vaccine for the coronavirus pandemic. The vaccine is being developed in association with Kaiser Permanente Washington Health Research Institute and is currently in the second phase of human trial.

Germany coronavirus vaccine status

BioNTech-Pfizer is the candidate vaccine being co-developed by German biotech firm BioNTech and US pharmaceutical giant Pfizer. The vaccine has completed phase 1 human trials. The vaccine will now be tested on a large group of healthy people (nearly 30,000). The next stage of human trials is likely to begin from the last week of July.

There are several other candidate vaccines in different stages of trials being developed by Russia, France, Israel and Italy. Recently, Israeli Defence Minister Naftali Bennett has claimed a “significant breakthrough” in the process of developing a vaccine for coronavirus. He said that scientists at Israel’s Institute for Biological Research (IIBR) have developed an antibody to the novel coronavirus. However, there has not been any significant update about it after that. 

Coronavirus  is finding new victims worldwide, giving rise to frightening clusters of infection that increasingly seems to confirm what many scientists have been saying for months: The virus might linger in the air indoors, infecting those nearby. If airborne transmission is a significant factor in the pandemic, especially in crowded spaces with poor ventilation, the consequences for containment will be significant. Thus, there’s pressure from governments on pharmaceutical companies and scientists to come up with a vaccine as soon as possible.
