  • So far, limited data suggests an AstraZeneca shot followed by the Pfizer shot is safe and effective

Can you mix and match two-dose COVID-19 (coronavirus) vaccines?

It’s likely safe and effective, but researchers are still gathering data to be sure.

The authorized COVID-19 shots around the world are all designed to stimulate your immune system to produce virus-fighting antibodies, though the way they do so varies, noted Dr. Kate O’Brien, director of the World Health Organization’s vaccine unit.

“Based on the basic principles of how vaccines work, we do think that the mix-and-match regimens are going to work,” she said.

Scientists at Oxford University in the United Kingdom are testing combinations of the two-dose COVID-19 vaccines made by AstraZeneca, Moderna, Novavax and Pfizer-BioNTech. Smaller trials are also ongoing in Spain and Germany.

“We really just need to get the evidence in each of these (vaccine) combinations,” O’Brien said.

So far, limited data suggests an AstraZeneca shot followed by the Pfizer shot is safe and effective. The combination also appears to come with a slightly higher likelihood of temporary side effects like aches and chills.

That might be because mixing and matching different types of vaccines can often produce a stronger immune response, said Lawrence Young, a virologist at the University of Warwick in the United Kingdom.

In some places, health officials already suggest mixing in select circumstances.

After the AstraZeneca vaccine was linked to extremely rare blood clots, many European countries including Germany, France and Spain recommended people who got it as a first dose get a Pfizer or Moderna shot as a second dose instead.

In Britain and Canada, officials say people should aim to get the same vaccine for their second dose if possible. If they got AstraZeneca as their first shot, they’re advised to get another vaccine only if they have a history of blood clots or other conditions that might put them at higher risk of clots.

KABUL: The United Nations said on Friday that its main compound in western Afghanistan was attacked by "anti-government elements", killing at least one Afghan police guard and other officers injured.
"The area around Herat where the compound is located witnessed fighting today between the Taliban and government forces," a statement by the United Nations Assistance Mission in Afghanistan (UNAMA) said. It added the UN is urgently seeking to establish a full picture about the attack and is in contact with the relevant parties.
It was not immediately clear who attacked the compound.

  • The last round of talks ended in Vienna on June 20 and no date has been set for a new meeting

BERLIN: Germany’s foreign minister is signaling growing impatience with Iran, saying that a revival of the country’s frayed nuclear accord with world powers won’t be possible “forever,” a German magazine reported Friday.
The countries that remain parties to the agreement — Russia, China, Germany, France, Britain and Iran — have been trying during six rounds of talks in Vienna to resolve how the United States can rejoin and how Tehran can return to compliance. President Donald Trump pulled out of the agreement in 2018, but successor Joe Biden has said the US wants to return.
The last round of talks ended in Vienna on June 20. No date has been set for a new meeting.
“I am seeing with growing unease that Iran is delaying the resumption of the Vienna nuclear talks on the one hand, and on the other hand it is simultaneously moving further and further away from core elements of the agreement,” news weekly Der Spiegel quoted German Foreign Minister Heiko Maas as saying.
Since the US pulled out, Iran has gradually been violating the deal’s restrictions to put pressures on the remaining parties to come up with economic incentives to offset crippling American sanctions.
The accord, known as the Joint Comprehensive Plan of Action, or JCPOA, is aimed at preventing Iran from developing nuclear weapons. Tehran denies it is seeking any.
“We want a return to the JCPOA and are firmly convinced that it is in all sides’ interest,” Maas said. “But it is also clear that this option will not be open to us forever.”

  • Puigdemont and two former ministers are wanted in Spain on allegations of sedition
  • The European Parliament voted to strip them of immunity, but the trio appealed to the court

LUXEMBOURG: The EU’s General Court on Friday upheld a decision by the European Parliament to lift the immunity of former Catalan leader Carles Puigdemont and two fellow pro-independence allies.
The move overturned a ruling in June that had seen the separatist politicians provisionally regain the legal protections afforded to members of the parliament.
Puigdemont, along with that of former Catalan regional ministers Toni Comin and Clara Ponsati, are wanted in Spain on allegations of sedition following an attempt by the Catalan region to gain independence through a referendum that Madrid ruled was unconstitutional.
In March, the European Parliament voted to strip them of immunity, but the trio appealed to the court arguing that they ran the risk of jail which would prevent them from exercising their mandate as elected European lawmakers.
The latest ruling on Friday rejected the claim that Puigdemont — based in Brussels since fleeing Spain in 2017 — and his colleagues face imminent arrest.
“There is no reason to consider that the Belgian judicial authorities or that the authorities of another Member State could execute the European arrest warrants issued against the deputies and could hand them over to the Spanish authorities,” the court said.
But it added that the three lawmakers — elected to the European Parliament in 2019 — could still reintroduce their demand to have their immunity reinstalled if authorities moved to arrest them and it became “sufficiently probable” they would be sent to Spain.
Madrid last month pardoned nine other jailed Catalan separatists behind the failed 2017 independence bid and released them from long prison sentences.


Airlift begins for Afghans who worked for US during long military campaign

Airlift begins for Afghans who worked for US during long military campaign
WASHINGTON: Some 200 Afghans were set to begin new lives in the United States on Friday as an airlift got under way for translators and others who risk Taliban retaliation because they worked for the US government during its 20-year war in Afghanistan, US officials said.
The operation to evacuate US-affiliated Afghans and family members comes as the US troop pullout nears completion and government forces struggle to repulse Taliban advances.
The first planeload of some 200 evacuees were expected to be bused to Fort Lee, a US military base in Virginia, for final paperwork processing and medical examinations.
The Afghans who worked for the United States are being granted Special Immigrant Visas (SIV) entitling them to bring their families. As many as 50,000 or more people ultimately could be evacuated in “Operation Allies Refuge.”
The first group is among some 2,500 SIV applicants and family members who have almost completed the process, clearing them for evacuation, said Russ Travers, President Joe Biden’s deputy homeland security adviser.
The Afghans were expected to remain at Fort Lee for up to seven days before joining relatives or host families across the country.
The evacuees underwent “rigorous background checks” and COVID-19 tests, Travers added. Some were already vaccinated, and the rest will be offered jabs at Fort Lee.
The surging violence in Afghanistan has created serious problems for many SIV applicants whose paperwork is in the pipeline amid reports — denied by the Taliban — that some have been killed by vengeful insurgents.
Some applicants are unable to get to capital Kabul to complete required steps at the US embassy or reach their flights.
“We do lack the capacity to bring people to Kabul from other parts of the country or to house them in Kabul,” Tracey Jacobson, State Department coordinator of the operation, told reporters.
The SIV program has been plagued by long processing times and bureaucratic knots — which the Biden administration and Congress are working to undo — that led to a backlog of some 20,000 applications. The State Department has added staff to handle them.
“The US has had 20 years to anticipate what the withdrawal would look like,” said Adam Bates, policy counsel for the International Refugee Assistance Project, which provides legal aid to refugees. “It’s unconscionable that we are so late.”
Kim Staffieri, co-founder of the Association of Wartime Allies, which helps SIV applicants, said surveys the group has conducted over Facebook show that about half of SIV applicants cannot reach Kabul, including many approved for evacuation.
Congress created SIV programs in 2006 for Iraqi and Afghan interpreters who risked retaliation for working for the US government.

India reports most new COVID cases in three weeks
  • The nationwide tally of infections has reached 31.57 million, according to health ministry data

NEW DELHI: India reported 44,230 new COVID-19 cases on Friday, the most in three weeks, the latest evidence of a worrying trend of rising cases that has forced one state to lock down amid fears of another wave of infections.
India was battered by the Delta variant of the virus in April and May but the rate of spread of infections later eased off. It has again been rising, with higher numbers in seven of the past eight days.
The nationwide tally of infections has reached 31.57 million, according to health ministry data. Deaths rose by 555 overnight, taking the overall toll to 423,217.
Medical experts polled by Reuters in late June said a third wave of coronavirus infections was likely to hit India by October, though it would be better controlled than the devastating April-May outbreak.
Health experts have called for faster vaccinations to stave off another big surge.
The government estimates that 67.6% of the 1.35 billion population already have antibodies against the coronavirus, with nearly 38% of the adult population of about 944 million people having received at least one vaccine dose.
The disease's estimated reproduction rate, or R value, has also inched up in the past week,
The R value hit 1 on July 24 - meaning on average, every 10 people infected will infect 10 other people - for the first time since May when daily infections were near a peak of 400,000.
The southern state of Kerala announced a new lockdown on Thursday while movement restrictions are in place in some northeastern states reporting a rise in infection rates.
Other places, including the capital New Delhi, have recently reopened most economic activities.
