Coronavirus Vaccine News Live Updates July 23: Russia expects vaccine by fall Coronavirus Vaccine News Live Updates July 23: Russia expects vaccine by fall

As the world paces towards an efficient coronavirus vaccine, one pertinent question emerges -- when is the COVID vaccine likely in the market? The answer might not be very simplistic. Microsoft co-founder Bill Gates believes that multiple doses of the vaccine would be required, unlike what was expected earlier. This throws a spanner in the works. Nevertheless, Pfizer believes that in the best case scenario, a vaccine could be available by year end. Serum Institute of India CEO Adar Poonawalla, for instance, believes that a COVID-19 vaccine could be ready and available by year-end. Serum Institute is manufacturing the Oxford University-AstraZeneca vaccine that has advanced to the latter stages and has reported positive results in the first phases of trial. A WHO expert believes that people could start getting vaccinated by the first part of next year. Meanwhile, Russian Prime Minister Mikhail Mishustin has said that he is optimistic of a reliable COVID vaccine by fall.

It must be mentioned that there are multiple contenders from several countries in the race to find the first coronavirus vaccine. In India too, several pharmaceutical companies are working towards a vaccine -- some have advanced to trial phases. Bharat Biotech, Zydus Cadila, Indian Immunologicals, Nynvax, Panacea Biotec, and Biological E are some of the Indian companies working towards the vaccine. Multiple hospitals have started screening volunteers for COVAXIN trials. Screening for volunteers will wrap up in July-end.

12:15 pm: Coronavirus Vaccine Tracker: COVAXIN results to take three months

AIIMS said that the COVAXIN trials would take at least three months for researchers to arrive at the first set of data. "It (starting trials) is heartening because it's an indigenous vaccine; making a new vaccine is an achievement. Even if a vaccine is first developed somewhere else in the world, India will be mass producing it. We are good at it," said AIIMS Director Dr Randeep Guleria.

11:40 am: Latest News on Coronavirus vaccine: 'Too early to sign deal for vaccine,' says Harsh Vardhan

Health Minister Dr Harsh Vardhan has said that it is too early to sign a deal with pharma companies to procure coronavirus vaccines. "I do not know about the details of this particular vaccine candidate but there are more than 200 trials happening around the world currently for developing a vaccine against Covid-19, and all are currently far from the stage of manufacturing. None of these are a ready vaccine, rather, these are merely vaccine candidates," he said. He also added that it is too premature to put put government's vaccine procurement and roll-out plan in public.

11:30 am: Coronavirus vaccine: When will we have one?

Boris Johnson's medical advisor has said that the chances of a coronavirus vaccine by year-end is 'very low'.

"But how many of them develop a severe disease is still not very clear because these numbers are very small," he said.

10:42 am: Pfizer coronavirus vaccine possible by year end in best-case scenario

Pfizer and collaborator BioNTech are hoping to seek regulatory approval as early as October. In the best-case scenario there would be a coronavirus vaccine by the year end, it said. "An interesting thing about this vaccine approach is that the mRNA is enclosed in a lipid nanoparticle, so you can imagine the complexity of that. At this site, we are looking at engineering that particle and analyses for it that will allow clinical trials as well as the manufacturing to occur," Burkhardt said," John Burkhardt, Senior Vice President, Drug Safety Research and Development at Pfizer

A senior scientist at Johns Hopkins Applied Physics Laboratory also said that there have been very little mutation observed so far.

"I think it is important for the general public to understand that COVID-19 is not the only virus or infectious disease in our society currently. the best protection against COVID-19, in particular, will be its own vaccine. Until one is approved, eating healthy, staying physically active and taking supplements like zinc, and vitamins C and D, utilising hand sanitiser and wearing masks will help keep one's immune system strong," said Burnett.

10:03 am: Nobel laureates advocate 'human challenge trials'

Over 100 top scientists including 15 Nobel laureates have advocated for volunteers to be exposed to coronavirus for vaccine development purposes. This deliberate exposure is called 'human challenge trials'. It is a controversial move, especially for a disease like coronavirus that does not have a cure yet. "If challenge trials can safely and effectively speed the vaccine development process, there is a formidable presumption in favour of their use, which would require a very compelling ethical justification to overcome," the scientists wrote in a letter to US National Institutes of Health (NIH).

WHO and UNICEF have warned that there is an alarming decline in the vaccinations of other diseases amid coronavirus pandemic.

Similarly Professor Adrian Hill who is heading the team of researchers at Oxford has also said that the vaccine is possible within this year. "If we got a result in, say, October and we had emergency use licensure (ph) by November, we would certainly hope to have many millions of doses available then in different countries from different manufacturers," Hill said in an interview in NPR.

Head of WHO's emergencies programme Mike Ryan has said that while there are multiple contenders and many companies have made significant progress, the likely time for a coronavirus vaccine in the market is not before 2021.
