(CNN)Mass public vaccination programs are underway across the globe. In the United States, Dr. Anthony Fauci told NBC that President-elect Joe Biden’s goal to distribute 100 million doses of Covid-19 vaccine in his first 100 days of office was “quite feasible.”

India, which trails only the US in total cases, began an ambitious nationwide vaccination drive this weekend after regulators approved the AstraZeneca/Oxford shot and a locally produced vaccine. In Turkey and Indonesia, tens of millions of people are poised to receive doses of the CoronaVac shot made by Beijing-based company Sinovac, Helen Regan reports.

England has just expanded its vaccine program to people aged 70 and older, while South Korea’s president says he believes the country will have complete Covid-19 “herd immunity” by November.

There’s an urgency to these rollouts. The world hit 2 million coronavirus deaths last week, and policy makers are scrambling to stem the human and economic toll wrought by the pandemic. The Chinese and Indian vaccines are regarded as potentially affordable and easily distributed shots, and unlike the Pfizer/BioNTech and Moderna vaccines, they do not require expensive cold storage.

But there have been queries over the effectiveness of the Sinovac vaccine, which was revealed to have an efficacy rate of just 50.38% in late-stage trials in Brazil — significantly lower than earlier results showed. The makers of India’s homegrown vaccine, Covaxin, have also faced criticism from experts for not revealing the vaccine’s efficacy results or any other data from its clinical trials.

Amid the questions, countries are re-examining their rollout plans. Singapore’s Health Minister said officials would review Sinovac’s vaccine before any rollout to its citizens. Concern is growing in Australia — which has secured 54 million doses of the Oxford/AstraZeneca shot — that relying on a single vaccine with a lower efficacy rate may not necessarily build up the required herd immunity in its 26-million-strong population. Some scientists are calling for a delay to mass inoculations.

New Zealand, hailed as a global model for how it handled the outbreak, has yet to approve a vaccine, though it has struck deals with several vaccine developers for access to their candidates once local regulators give the green light. Experts say its wait-and-see approach will mean the population will be able to have greater confidence in the vaccines. But it could be a risky bet — particularly given new, potentially more transmissible variants, could risk further outbreaks.

Q: What kind of Covid-19 test is considered acceptable for travelers entering the US?

A: Last week, the US Centers for Disease Control and Prevention (CDC) announced that, as of Tuesday, January 26, all air passengers ages two and older must show proof of a negative Covid-19 test to enter the country.

This means travelers bound for the US on international flights must have a viral test. PCR and antigen tests both qualify.

WHAT’S IMPORTANT TODAY

Vaccination rates highlight stark differences between Israelis and Palestinians

At least 4.5 million Palestinians living on the West Bank and in Gaza are being left behind by Israel’s world-leading vaccine rollout, Sam Kiley reports. So far none has had the injections, and most are unlikely to get them any time soon — because there is no Covid-19 vaccination campaign in the Palestinian territories.

A UN expert report says that Israel is the occupying power in and over Gaza and the West Bank, and has been since 1967, and is thereby ultimately responsible for the health care of those living under occupation. But as Israel’s vaccination campaign climbs past 20% of its population (including east Jerusalem residents), Israel’s government has pointed to the Oslo accords, signed in the mid-1990s with the Palestine Liberation Organization, which led to the creation of the Palestinian Authority (PA). Included in the first of those agreements is a clause that hands responsibility to the PA for the health of all Palestinians under its civil administration.

Experts admit it is not a straightforward task trying to navigate between the responsibilities assigned by Oslo, which was not a final status agreement, and the duties laid out under the Geneva Conventions.

UK leads Europe’s vaccination race as it closes travel corridors

England is expanding into the next phase of its vaccination campaign, offering doses to people aged 70 and over and those considered vulnerable to the virus, the government announced Sunday. So far, more than 3.5 million people received a first dose of a Covid-19 vaccine in the UK, surpassing the number who have tested positive for the virus, according to government data.

While the UK was the first in the world to start a mass vaccination rollout, and has vaccinated more people than some of the European Union’s biggest nations, the country has suffered the highest Covid-19 death toll in western Europe, of more than 89,000 deaths, according to Johns Hopkins University figures. Fears over new Covid-19 variants have also led it to close all travel corridors today, meaning all travelers coming into the UK must have a negative Covid-19 test and will have to quarantine for 10 days on arrival.

The inoculation drive has seen England's historic Salisbury Cathedral transformed into a vaccination center, with patients given shots while organ music was played in the picturesque building.

Norway assesses deaths in frail elderly patients following vaccinations

Norway is looking into the death of 23 patients who had received the Pfizer/BioNTech vaccine. Thirteen of the deaths have so far been assessed by Norwegian authorities and the assessments suggest that common adverse reactions to mRNA vaccines, such as fever and nausea, may have contributed to a fatal outcome in some frail patients, said Sigurd Hortemo, chief physician at the Norwegian Medicines Agency.

As the country is vaccinating the elderly and people in nursing homes with serious underlying diseases it should be “expected that deaths close to the time [of the] vaccination may occur. In Norway, an average of 400 people die each week in nursing homes and long-term care facilities,” the country’s Institute of Public Health said in a statement. Pfizer said in a statement to CNN that it is working with Norwegian authorities to gather all the relevant information, adding that the “the number of incidents so far is not alarming, and in line with expectations. All reported deaths will be thoroughly evaluated [by the Norwegian Medicines Agency] to determine if these incidents are related to the vaccine.”
