World crosses 50 million COVID cases but this country in the Pacific just got its first

The Pacific nation had been among the last few countries to have avoided the virus altogether.

Vanuatu has recorded its first case of the coronavirus after a citizen who had been repatriated from the United States tested positive while in quarantine.

The Pacific nation had been among the last few countries to have avoided the virus altogether.

Health authorities say the 23-year-old man was asymptomatic when he returned on Nov. 4 and his infection was confirmed Tuesday after routine day 5 testing.

Authorities say they plan to keep everyone from the same flight in quarantine and to trace the man’s close contacts but don’t need to impose any broader measures in the nation of 300,000 people.

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.

In other developments in the Asia-Pacific region:

— India’s capital has recorded a new peak of 7,830 new coronavirus cases in the past 24 hours as festivals and weddings attended by large crowds fuel a resurgence. Authorities targeted testing in shopping areas, workplaces and religious places with New Delhi’s tally continuing to be more than 7,000 daily this week after dropping to nearly 1,000 in September. India's infections overall have held steady recently with 44,281 new cases reported Wednesday.

The Health Ministry also reported 512 deaths, taking total fatalities to 127,571. Testing in India has generally remained opaque, with the government not sharing the total share of rapid tests that India has used to boost its testing levels in the past months. The rapid antigen tests can miss infections, while the RT-PCR molecular tests are more reliable.

— A leading Chinese health official has expressed confidence the country may avoid a second wave of coronavirus infections this winter if it maintains current precautions. Feng Zijian, deputy director of the Chinese Center for Disease Control and Prevention, told leading financial magazine Caixin that China “will very likely prevent” a new round of infections given present trends. Feng described the present state of the outbreak in China as “very safe overall.”

China has largely eliminated new local outbreaks by requiring masks indoors and on public transport, requiring two-week quarantines for those entering the country and banning some foreign travelers entirely. Authorities have quickly moved to address local outbreaks by tracing potential contacts, carrying out widespread testing and sometimes locking down entire communities.

While China was accused of suppressing information about the outbreak at its initial stage, its recent data have not been seriously challenged and local officials have moved swiftly to disclose new cases. That has allowed the world’s second-largest economy to largely recover, partly with the help of the country’s thriving home delivery services.

— The number of South Koreans with jobs annually declined for the eighth straight month in October, a streak unseen since a 2009 financial crisis. Statistics Korea on Wednesday said the number of employed people in the country was measured at 27.09 million last month, 421,000 fewer than a year earlier, with fears of viral spread and global lockdowns decimating jobs in both domestic service industries and export-driven manufacturing sectors.

“The (domestic) resurgence of COVID-19 since August and the prolonging of the virus crisis have expanded the job losses,” Statistics Korea official Chung Dong-myung during a briefing. The country added 146 new cases on Wednesday, its fourth straight day of over 100, bringing its caseload to 27,799, including 485 deaths.

— New Zealand’s central bank is making more monetary moves to counter the economic downturn caused by the pandemic. The Reserve Bank says that from December, it will provide retail banks with lower funding costs, allowing them, in turn, to lower borrowing rates for companies and households.

That's in addition to a large asset-buying program already introduced by the central bank. The bank also announced Wednesday that it was keeping its benchmark interest rate at a record low 0.25% and was considering lowering it to zero or to a negative rate next year. But the bank also said it was considering reintroducing mortgage restrictions from next March due to concerns about an increase in house prices and high-risk lending to housing investors.
