Kiribati and Samoa entered lockdowns Saturday after overseas arrivals brought Covid to the Pacific island nations that had avoided the worst of the pandemic for two years.
But authorities in both countries have been forced to put in place stay-at-home orders after the virus was detected in international arrivals.
Dozens of passengers on a flight to Kiribati from Fiji -- the first to arrive in the nation since borders reopened -- tested positive for the virus.
And in Samoa, the restrictions were triggered after cases linked to a repatriation flight from Brisbane rose to 15, prime minister Fiame Naomi Mata'afa said.
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.
The restrictions will lift on Monday night and all current cases -- believed to be infected with the Omicron variant -- are in quarantine, she added.
Kiribati's leader said the capital -- home to almost half of the country's 120,000 population -- would be placed under the restrictions after recording its first community cases.
"There is now an assumption that Covid-19 is now spreading in the community," President Taneti Maamau said in a statement on Facebook.
Under the restrictions, locals must stay home unless in need of essentials like food or healthcare.
It was unclear how long the lockdown would last, but a previous announcement said similar restrictions would end Thursday.Around 62 percent of Samoa's population is fully vaccinated, while about 34 percent of Kiribati's population is double-jabbed, according to WHO data.
