Singapore has cancelled the passport of one of its citizens who was found to have flouted the requirement to quarantine himself after returning from overseas, according to a Bloomberg report.
The man, not named by the publication, arrived in Singapore onboard a ferry from Batam, Indonesia on March 19. He left for Indonesia the same day, despite having been issued a notice to stay home for a period of 14 days.
The person returned to Singapore on March 24 and was issued a second notice.
The city-state has imposed strict measures to help contain the spread of the novel coronavirus pandemic. Under these measures, persons making false or misleading travel declarations can be prosecuted.
Earlier on March 29, Reuters reported that Singapore had registered its third coronavirus death, a day after the total infections there topped 800. The Health Ministry said the patient, a 70-year-old male Singaporean, had been in intensive care for 27 days before he passed and that he had some pre-existing conditions.
Frequently Asked Questions
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.
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.
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.
