Till now the WHO hasn't approved any vaccine against COVID 19. Hope that answers your question.

Since COVID 19 is caused by a virus, it is almost impossible to manufacture a vaccine that is 100% effective. Many of the health agencies are saying that they will approve a potential vaccine, if it's proven to be 50% to 70% effective. Russia and China has started mass-production of their vaccines, although these don't have the approval from the WHO.

I have seen a lot of posts on this thread claiming that Conor is a MMA fighter and he stands no chance in the boxing ring. I have to disagree here. Manny Pacquiao may be the overwhelming favorite, but it is not going to be a cakewalk for him. Conor is at his prime, and he has taken part in boxing before (although it ended in defeat, against Floyd Mayweather in 2017). I would say that the risk is too great to bet in favor of Manny.

The CSK bowling was not up to the mark. They won the game only because of Watson/du Plessis. None of the other players can claim any role in this victory. Dubai International Cricket Stadium is such a big ground and even then the CSK bowlers conceded 178 runs in 20 overs. Chahar and Jadeja were the only bowlers who escaped punishment. And Dhoni made a big blunder by not allowing Chahar to bowl his full quota of overs.

This is really surprising. Kucoin actually claimed that they had identified most of the hackers and have traced back a majority of the stolen funds. However, if the criminals are moving the funds with ease and liquidating them, then their claims are false. They may be trying to pacify their clients, by giving false assurances. Unfortunately for the Kucoin users, there is very little chance of anyone reimbursing their losses. 

I don't think that the demand for treasury bonds from the United States is going down. On the other hand, the interest in them seems to be going up. Average Yield for a 10-year bond is somewhere around 2% right now, and it is declining with every passing year. If the demand is low, then the interest rate should be going up. I agree that having consecutive budget deficits are not good for the economy. But tell me one thing. Among all the UN members, how many countries are having surplus budgets right now? Even countries such as Saudi Arabia are having huge budget deficits.

You can expect the stock markets to crash very badly, if Biden wins. During Trump's term the Dow Jones Industrial Average went up from 18,847 to 27,682.81, which represents an increase of 47% in just 4 years. No other president can claim something like this. All these gains will vanish in case Biden/Kamala gets elected. I am wondering whether I should sell my stocks, since Biden is well ahead as per the opinion polls.

Factually incorrect article. The Russians are going to mass produce their vaccine from this month onwards and they are saying that by the end of 2021, around 2 billion doses may be made available. Also, the vaccine from one of the Chinese firms will be available in the market shortly. The OP is mentioning the vaccine from University of Oxford/AstraZeneca, but I guess we will be having much better options by 2021.

For the last two matches, Francois du Plessis is opening the batting along with Shane Watson. The du Plessis/Watson combo seems to be doing much better than Vijay/Watson. But the middle order still looks vulnerable. I forgot the last time Kedar Jadhav scored a half century. He has scored 51 runs from 4 matches so far, and I don't know how this guy finds a place in the playing XI all the time.

There is a lot of intermarriage nowadays in the United States. A few months back, I read a statistic claiming that more than 30% of the black births are to mothers who are not black themselves. So in case a child is born to a father, who is a descendant of a slave and a mother, who is descendant of a slave-owner, will he/she be eligible for reparations? Also, blacks were not the only group to be enslaved. Asians, Whites (especially Irish and Slavs) as well as Native Amerindians were enslaved in the recorded history. Are their descendants eligible for reparations?

There is not a single country in the world, which will allow you to operate a cryptocurrency exchange without a valid license. I would say that it is sort of mixed package. You have to comply with KYC regulations and your transactions may no longer be anonymous. But at the same time, tighter regulations mean that there is a lower chance of the exchange owners conducting an exit scam.

At least this time they didn't hacked his Twitter account. These sort of attempts have been very common in Twitter over the past few months. I posted about one such attempt in the "Scam Accusations" subforum sometime ago. If you are unfortunate enough to click the phishing link, then it will take you to a very sophisticated web page. Only the experienced users will understand that everything shown there is faked. These criminals are very innovative.

Back in 2016, Trump as a politician was a new comer. His opponent (Hillary) had a lot of past baggage and a large section of the population voted for Trump not because they agreed with his policies, but because they wanted to make sure that Hillary never becomes the president. Times have changed. Trump's disapproval ratings have remained consistently in the 50-55% range, and his opponent this time is regarded as a moderate (I am talking about Biden, and not about Kamala).

If they want to include Gayle, then they needs to drop either Glenn Maxwell or Nicholas Pooran. Maxwell is not in good form right now, but they want to stick with him. For today's match, they dropped Karun Nair and included Mandeep Singh. Mandeep performed well today. So at least one of their changes worked. They have included Chris Jordan as well, and let's see how that goes.

This is a controversial topic. But from what we have seen, there is very little evidence to prove that third party candidates will have an impact on the outcome of the elections. They get very few votes and most of these votes come from those who want to cast protest vote. The votes received by such candidates doesn't lower the vote count for the main candidates. And for the POTUS 2020 elections, none of the third party candidates have received any attention from the media.

Well.. I never said that it is going to be easy. No matter how small the boundaries are, the required run rate is still above 12 runs per over (i.e 2 runs per ball). It is not going to be easy. But David Warner is not someone who will get intimidated with such a steep asking rate. As long as Warner is there, it is going to be advantage SRH. If he gets out sometime soon, then the outcome will get unpredictable.

Any new development on this topic? If they actually manages to get hold of the hackers, then it will be an exception. We had dozens (if not hundreds) of exchange hacks since 2014 and not even once the actual perpetrators were captured and the stolen funds were recovered. I just hope that this time they manage to get hold of the thieves and make an example out of them. Even if they manage to recover a part of the funds, it is going to be huge.

Right now there is no logic in keeping the fees very high. The fee reward doesn't constitute for more than 20% of the income for the miners. It is causing a lot of damage to the adoption and acceptability, and at the same time the miners are not gaining much out of it. And as you pointed out, those who transact small amounts are worst hit. Imagine paying $5 as fees for a transaction that is worth just $25.

Right now, it looks like SRH is having the advantage. They are 91/1 after 9 overs. They lost Bairstow early, but Warner and Pandey have stabilized the innings. Also they have Kane Williamson at no.4. Apart from Krunal Pandya, almost every other MI bowler has gone for plenty of runs. And Bumrah has been a big disappointment so far. In this game also his performance was not up to the mark.

If Russia ignores this conflict, then in the end they will also get caught up. Do you really think that Erdoğan and his puppet Aliyev will be satisfied with just Karabakh and Armenia? Their primary aim is obviously to complete what they couldn't finish in 1915-18. But what will happen after that? Erdoğan wants to establish the greater Turkestan and to become the Caliph. His idea of Turkestan includes the Caucasus, Volhynia and Siberia (which forms a part of Russia presently). Also, he would like to include Northern part of Iran (which is mostly populated by the Azeris). For now, Armenians are the target. Russians, Greeks, Serbs and the other non-Turkic people in this region can ignore this conflict as of now. But they will become the target sometime soon.

Update: Armenian side is suffering disproportionately high casualties, with 51 soldiers KIA yesterday. Total military casualties on the Armenian side is now above 200. The UAVs provided to Azerbaijan by Israel has singlehandedly shifted advantage to the Azeri side. The vast majority of the Armenian casualties and equipment damage resulted from drone strikes.

It happens time to time. You can check the Mempool size here:
 
https://www.blockchain.com/charts/mempool-size

Mempool size is the total size of the transactions which are to be confirmed. If the size is high, then the transaction fees also will be relatively high. Last time I checked, the size was around 32 million Bytes. Assuming that the average Block size is 1.2 MB, it is going to take around 30 blocks to confirm all these pending transactions, in case no new transactions are added.
