Imagine a place where 8-10 people live in 100 square feet structures. A place which squeezes close to 6,50,000 people, 5,000 small factories, and about 15,000 single-room workshops in just 2.5 square kilometer area. Welcome to  Dharavi, the biggest slum of Asia situated in the heart of fashion, entertainment, and commercial capital of India, Mumbai.

When the first COVID-19 case was discovered in Dharavi, it caused massive panic among the citizens as well as officials. Social distancing is virtually impossible to achieve in Dharavi, which is a maze of narrow congested lanes with tenements on either side of it and where 80% of the population use community toilets.

With their fingers crossed, people were speculating about Dharavi turning into a graveyard. These fears turned out to be misplaced and three months later Dharavi won praise from the WHO for effectively restricting the spread of coronavirus. According to the official data, the COVID-19 case doubling rate improved greatly, from 18 days in April, to 43 days in May, to 108 days in June, and 480 days in July.

Mr. Kiran Dighavkar, Assistant Commissioner of the top civic body of Mumbai, Brihanmumbai Municipal Corporation (BMC) said that their undertaking of an aggressive strategy of 4T’s - Tracing, Tracking, Testing & Treating, is the key to Dharavi’s successful fightback against the pandemic. The fightback plan was aptly coined "Mission Dharavi".

Extensive screening and testing of residents was done to detect the symptoms for coronavirus in "fever camp" which were set up by medical workers in different parts of the slum everyday. Many buildings such as schools, wedding halls, and sports complexes were overtaken by the civic authorities and were repurposed as quarantine facilities. A 200-bed hospital was also set up in record 14 days.

The BMC commissioner, I S Chahal said “Proactive screening helped in early detection, timely treatment and recovery.” Close to six hundred thousand people were screened, 14,000 people tested and 13,000 quarantined in nearby institutions, schools, marriage halls, and sports complexes. Furthermore, continuous monitoring of people’s movement using drones helped reinforce containment measures and scaled progress swiftly.

To further strengthen the measure, locals of the community emerged as “COVID Yodhas” (warriors) to address the concerns, a senior official said.  Many well endowed citizens and NGO’s provided Free meals, ration, PPE gear, oxygen cylinders, gloves, masks, medicines, and ventilators to residents and doctors.th July

On 8th July 2020 Dharavi recorded a total of 2,335 COVID-19 out of which 1,735 patients have recovered and there are only 352 active cases at present. Only 82 deaths were recorded in Dharavi till 8th July as against more than 4500 in the whole of Mumbai.

This phenomenal success has given the world a yet simple and effective technique in curbing the spread of the deadly virus. World Health Organization (WHO) chief Tedros Adhanom Ghebreyesus, in a virtual press conference in Geneva, acknowledging the efforts of various nations and Dharavi to contain the virus, said that “There are many examples from around the world that have shown that even if the outbreak is very intense, it can still be brought back under control”. Further, he added, “And some of these examples are Italy, Spain, and South Korea, and even in Dharavi -- a densely packed area in the megacity of Mumbai -- a strong focus on community engagement and the basics of testing, tracing, isolating and treating all those that are sick is key to breaking the chains of transmission and suppressing the virus.”

Asian countries & the race for COVID-19 Vaccine

Our relationship with the new strain of coronavirus is almost 8 months strong now. Countries like the US, Russia, UK, China, India, and many more have already set their brainy scientists in the task of developing a vaccine, turning it into a race which desperately needs a winner, since no one wants this deadly relationship to endure. Several attempts have proved to be successful, especially in countries like Russia, USA, India, and China.

China was the first to start scouring for a vaccine the day WHO declared that the new strain of SARS-CoV, originating in Wuhan-China, has resulted in a pandemic. It is a fierce competitor, especially to the US, as almost 8 of the 24 promising vaccines approved for clinical trials are from China. It used the technology of ‘inactivated vaccine’ which basically means killing the actual virus and using that to create a vaccine. This method is quite useful in treating measles and influenza, thus, increasing the chances of success in the case of COVID-19 as well.

“It’s a tried and true strategy”, Paul Offit, director of the Vaccine Education Center at Children’s Hospital of Philadelphia, said  about the inactivated vaccine. One potential vaccine from China-based Sinopharm is already in the phase 3 of trials whereas Sinovac will enter the third phase this month. Moreover, China has permitted Sinovac and Sinopharm to dilute phase 1 and 2 of vaccine trials on humans to hasten the process.

The head of the Chinese Center for Disease Control and Prevention, Gao Fu, had also been injected with a potential vaccine on July 28, 2020. “I’m going to reveal something undercover: I am injected with one of the vaccines'' Gao Fu said in a webinar hosted by Alibaba Health, an arm of the Chinese e-commerce giant, and Cell Press, an American publisher of scientific journals. However, he did not reveal any more details about how and when exactly he administered himself with the vaccine and ‘hopes’ that the vaccine works.

Elsewhere in Russia, on August 11, 2020, President Vladimir Putin proudly announced that Russia was the first country to grant regulatory approval to their vaccine after carrying out human trials for less than 2 months by the Gamalei Institute in Moscow. Regulatory approval permits vaccination of the masses. Although it has not undergone phase 3 of trials, Russia expects to initiate mass production of the vaccine by the end of this year. Kirill Dmitriev, head of Russia's sovereign wealth fund states that the vaccine will be called ‘Sputnik V’, named after Sputnik 1, the first satellite launched by Soveit Union which was a euphoric moment for Russia. More recently, China and Russia have joined hands in proceeding with the clinical trials of their vaccines.

These two instances seem to bring a new hope for the future, yet raise alarms and invite scepticism from the experts in the field of public health. One major concern is that without prolonged trials, vaccines should not be authorized for public use. Anthony Fauci, an infectious disease expert based in the US said “I do hope the Chinese and the Russians are actually testing the vaccines before they are administering the vaccine to anyone. Because claims of having a vaccine ready to distribute before you do testing is problematic at the very least”. Hence, some people are still in doubt regarding the safety of the product. Putin, however, rubbished such concerns and said "I know that it works quite effectively, forms strong immunity, and I repeat, it has passed all the needed checks".

An Indian biotechnological company, Bharat Biotech developed ‘Covaxin’ in collaboration with Indian Council for Medical Research (ICMR), using the mechanism of inactivated vaccine. It was successful in getting approval for human trials which were scheduled to begin in July, 2020. Initial reports stated that it would be ready for mass use by August 15, 2020, which also marked the 73rd Independence Day of India. However, Bharat biotech was clear in letting the public know that phase 1 of the trials are still on-going. ICMR cleared the confusion by stating that it would prepare the results of the phase 1 trials by August 15, 2020, not the actual vaccine for use. Phase 2 of the trials are awaited in September, 2020.

So far, the results of phase 1 trials have been positive as no serious side-effects are observed in the vaccine candidates. “The vaccine has been safe. No adverse effect has been reported. Even the point of injection pain, which is normal in vaccines, has been very mild” said Dr Kushwaha of Prakhar Hospital.

Meanwhile, the South Korean government stated on August 21, 2020, that it will secure adequate vaccine supply to its citizens by cooperating with international bodies and promoting local drug development. Three South Korean companies have started the process of making a vaccine and all are in the clinical trial phase. Bill Gates asserts that the South Korean pharmaceutical company, SK Bioscience, will have around 200 million vaccine doses ready by June 2021.

Japan is jointly collaborating with the UK, France and other European countries to establish a $20 billion fund to buy coronavirus vaccines, with Japan pledging a contribution of $800 million. It’s vaccine program aims to focus on giving primary attention to its medical workers and the elderly people of the country when the first doses of the vaccine are made. The state-funded vaccination program is believed to be officially adopted by Japan in September this year with negotiations with the UK and US based drug makers already in place.

With the race to bring COVID-19 vaccine seemingly coming to a close and it will hopefully be ready by the end of 2020 or early 2021. Till then, the entire world is watching this race with bated breath.
