5 | India to get 100 million AstraZeneca's vaccine shots by December 2020, say Reports: With Covishield, the coronavirus vaccine candidate jointly developed by the University of Oxford and British firm AstraZeneca entering phase 3 trials, Serum Institute of India (SII) has started ramping up the production of the vaccine. The world's largest vaccine maker plans to have 100 million doses ready by December 2020 for an inoculation drive that could begin across India that same month, Bloomberg reported on November 13.

From US President Donald Trump saying the United States might have the coronavirus vaccine before November to Israel claiming it already has an 'excellent' vaccine against the coronavirus, here are all the latest updates on the development of the vaccine against COVID-19 on August 6:

Trump says coronavirus vaccine possible before November 3: Trump said it was possible the United States would have a coronavirus vaccine before the November election. This, according to news agency Reuters, is a far more optimistic forecast than that put forth by his own White House health experts.

Asked on the Geraldo Rivera radio program when a vaccine might be ready, Trump said, "Sooner than the end of the year, could be much sooner." When prodded and asked if it could be sooner than November 3, Trump reportedly said it is possible "in some cases, yes possible before, but right around that time."

Israel claims 'excellent vaccine in hand', set to start human trials Israel claimed it already has in hand an 'excellent' vaccine against the coronavirus pandemic, but it has to go through regulatory processes, which are set to begin with human trials following the autumn holidays.

Human trials of coronavirus vaccine set to begin in Indonesia Human trials on a potential coronavirus vaccine are due to start in Indonesia next week as part of a collaboration between state-owned pharmaceutical company Bio Farma and China's  Sinovac Biotech, a senior researcher said.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.

The phase 3 clinical trial is set to begin on August 11 and will involve 1,620 volunteers aged between 18 and 59, Professor Kusnandi Rusmil, Head Researcher at Bandung’s Padjadjaran University, said.

Half of the participants will receive the vaccine over a six-month period, while the rest will receive a placebo, he said, noting 800 volunteers had been signed up so far.

AstraZeneca in first COVID-19 vaccine deal with Chinese company Shenzhen Kangtai Biological Products will produce AstraZeneca's potential COVID-19 vaccine in China, the British drugmaker said on August 6, its first deal to supply one of the world's most populous countries.

The deal underscores Astra's frontrunner position in a global race to deliver an effective vaccine, given that Chinese ventures are leading at least eight of the 26 global vaccine development projects currently testing on humans, news agency Reuters reported.

Under the agreement Shenzhen Kangtai, one of China's top vaccine makers, will ensure it has annual production capacity of at least 100 million doses of the experimental shot AZD1222, which AstraZeneca co-developed with researchers at Oxford University, by the end of this year, AstraZeneca said.
