Study: Risk from virus variants remains after first Pfizer jab

A single dose of Pfizer's vaccine may not generate a sufficient immune response to protect against dominant new variants, except in people who have already been infected, a UK study has found.

The Imperial College-led study, which looked at immune responses in British healthcare workers after their first dose of the Pfizer shot, found that people who had previously had mild or asymptomatic infection had enhanced protection against more infectious mutated variants that emerged in Britain and South Africa.

But the immune response after a first dose of the shot was weaker in people who had not previously been infected, potentially leaving them at risk from such variants, researchers leading the work said on Friday. 

Turkey’s death toll tops 40,000

Turkey's death toll has surpassed 40,000, authorities said.

A total of 31,891 cases, including 2,673 symptomatic patients, confirmed across Turkey in the past 24 hours, according to the latest Health Ministry data.

Turkey’s overall caseload is now over 4.82 million, while the nationwide death toll rose by 394 over the past day to reach 40,131.

UK reports over 2,300 new cases

Britain has reported 2,381 new cases reported, down from 2,445 a day earlier, according to government data

Britain also recorded 15 deaths within 28 days of a positive test, down from 22 on Thursday, while the number who had received the first dose of a vaccine rose to 34.2 million.

Number of French patients in intensive care falls

The country has reported 4.02 million cases to date.

Mexico expects 5M more AstraZeneca doses from US

Mexican President Andres Manuel Lopez Obrador has said he expects the United States to send Mexico around 5 million more doses of the AstraZeneca vaccine to help with its efforts to inoculate the population.

Speaking at a regular news conference, Lopez Obrador told reporters that it was "probable" that the United States would make his country a loan of the 5 million doses while Mexico got its own production of AstraZeneca vaccine up and running.

Some EU nations still want Valneva vaccine deal 

Some EU countries still want Brussels to strike a deal to buy Valneva's vaccine candidate despite a recent setback in talks, as the bloc aim to shore up and diversify supplies, sources familiar with the talks have told Reuters.

A spokesman for the European Commission said last week the French vaccine maker had not met conditions required to reach an agreement, two days after the company said it would now give priority to a country by country approach.

Sri Lanka declares worst economic downturn in 73 years

Sri Lanka has announced that its economy shrank 3.6 percent last year due to the pandemic, making it the worst downturn since independence from Britain in 1948.

The unprecedented recession compared with a 2.3 percent GDP growth in 2019, the Central Bank of Sri Lanka said in its annual report for 2020.

Brazil calls on countries to share spare vaccines

Countries should share spare vaccine doses with hard-hit Brazil to help the global fight against the virus, including the spread of new variants, Brazil's Health Minister Marcelo Queiroga told a World Health Organization briefing on Friday.

Queiroga said Brazil had given out 41 million vaccine doses but needed more supplies to meet a target of 2.4 million doses per day. 

Countries should contribute spare doses as soon as possible "so we can broaden our vaccination campaign and contain the pandemic at this critical time and avoid the proliferation of new variants."

Singapore hospital hit by rare outbreak

A Singapore hospital has locked down four wards after detecting cases, authorities said, a rare outbreak in a country that has largely brought the virus under control.

After a partial lockdown and rigorous regime of testing and contact tracing, the virus had almost disappeared in Singapore, with authorities in recent months reporting hardly any local transmission.

But there were 16 infections on Thursday — the highest daily count since July last year — and another nine on Friday.

Turkey grants emergency authorisation for Sputnik V use

Italy meets 500,000 daily vaccinations target

Italy has for the first time inoculated more than 500,000 people in a day, meeting a key coronavirus vaccinations target, the government said.

Authorities initially hoped to reach the milestone by mid-April, but pushed back the objective as supply shortages stymied immunisation efforts across Europe.

"Yesterday more than 500,000 doses of the vaccine were administered in Italy," Health Minister Roberto Speranza wrote on Facebook, hailing the institutional "team work" that led to the result.

France to offer jabs to all adults from June 15

French President Emmanuel Macron has said that vaccinations will be open to all adults from June 15, as he aims to quickly reopen the country as it battles a third wave.

People over 50 can meanwhile sign up for a jab from May 15, he added on Twitter, compared to an age limit of 55 currently.

Pfizer, BioNTech seek EU's OK to use vaccine on kids

Pfizer Inc. and BioNTech have submitted a request to the European drug regulator for the approval of their vaccine to be extended to include children 12 to 15 years old, in a move that could offer younger and less at-risk populations in Europe access to the shot for the first time.

In a statement, the two pharmaceuticals said their submission to the European Medicines Agency is based on an advanced study in more than 2,000 adolescents that showed their vaccine to be safe and effective. 

The children will continue to be monitored for longer-term protection and safety for another two years.

Spain studies mixed use of vaccines

Spanish health authorities have said they started giving Pfizer-BioNTech vaccine doses to participants in a government-led study involving young people who received a first dose of the AstraZeneca vaccine.

Researchers from Spain’s Carlos III Institute want to study the effects of mixing vaccines from different manufacturers as they look for a second dose alternative following very rare brain blood clots linked to the vaccine produced by AstraZeneca.

A total of 400 people were given the Pfizer-BioNTech vaccine for their second dose until Thursday, Spain’s Health Ministry said, while 200 other people have been recruited as part of the study's control group.

Five major hospitals across Spain are involved, and results are expected in mid-May.

AstraZeneca delivers 68M Covid-19 shots in first quarter

AstraZeneca says it has delivered about 68 million doses of its Covid-19 vaccine during the first three months of 2021 after the shot became one of the first approved for widespread use.

The Anglo-Swedish drugmaker reported $275 million in revenue from sales of the vaccine, or the equivalent of $4.04 per dose. 

AstraZeneca has pledged that it will deliver the vaccine on a non-profit basis as long as the pandemic lasts.

The company said 30 million doses of the vaccine went to the European Union, 26 million to the UK, 7 million to Gavi, an alliance that secures vaccines for low-income countries, and 5 million to other nations.

Hungary to ease virus curbs as vaccine rollout progresses

Hungary's Prime Minister Viktor Orban has said that parts of the service economy will reopen as scheduled on Saturday as the country's Covid-19 vaccination rate surpasses 40 percent, adding he would slowly refocus on kick-starting economic growth.

Hungary has the highest cumulative per capita coronavirus death toll in the world, according to, but the third wave of its epidemic is slowly receding.

The range of services reopening will include hotels, indoor restaurants, theatres, cinemas, gyms, sports venues, swimming pools, museums, libraries and zoos, Orban said, confirming earlier plans.

The premier, who faces his first tight election race in 2022 since assuming power a decade ago, has leveraged the rapid vaccine rollout to try to shore up his support base.

In March, more than 16,000 died in the nation of 10 million, a 40 percent annual increase and the highest figure for that month since a deadly flu outbreak in 1983, central statistics office KSH said on Friday. 

Uganda detects Indian variant

Uganda has detected the Indian variant of the novel coronavirus, igniting fears the East African nation could suffer a resurgence of cases just when its outbreak has waned, a senior health official said.

"Yes, we have got one individual who has that variant," Pontiano Kaleebu, head of the government-run Uganda Virus Research Institute (UVRI) told Reuters on Friday.

The variant, he said, had been detected in recent days on a Ugandan who had returned from a visit to India. He did not immediately have further information.

Health Ministry spokesman Emmanuel Ainebyoona told Reuters the country's coronavirus task-force would discuss the situation on Friday.

So far, Uganda, like many African countries, has experienced a relatively mild Covid-19 outbreak.

As of Tuesday, Uganda had reported 41,797 infections and 342 deaths, health ministry data showed.

Russia produces first batch of vaccine for animals

Russia has produced the world's first batch - 17,000 doses - of Covid-19 vaccines for animals, its agricultural regulator has said.

Russia registered Carnivac-Cov in March after tests showed it generated antibodies against Covid-19 in dogs, cats, foxes and mink.

The first batch will be supplied to several regions of Russia, the regulator Rosselkhoznadzor said in a statement.

It said companies from Germany, Greece, Poland, Austria, Kazakhstan, Tajikistan, Malaysia, Thailand, South Korea, Lebanon, Iran and Argentina had expressed interest in purchasing the vaccine.

The World Health Organization has voiced concern over the risk of transmission of the virus between humans and animals. 

The Russian regulator has said the vaccine would be able to protect vulnerable species and thwart viral mutations.

Hong Kong detects untraceable coronavirus variant

Hong Kong has detected an untraceable variant of coronavirus, forcing evacuation of a residential plot and immediate quarantine of the close contacts of the infected person, a health authority said.

According to a statement released by the Hong Kong Department of Health on Thursday, a positive case with the N501Y mutant strain of coronavirus was reported late evening.

“As N501Y mutant strain is with high transmissibility, the Centre for Health Protection decided to carry out prudent measures on infection control and prevention to arrange compulsory quarantine for asymptomatic residents of all units on all floors of the building concerned, so as to stop the potential risk of spread of N501Y mutant strain,” read the statement.

The source remains unknown, it said.

The case involves a 39-year-old woman from the Philippines who is a domestic helper and caretaker of a 10-month-old baby girl who also tested positive for Covid-19.

Health authorities issued the evacuation order for quarantine in Tung Chung area of the city.

Vaccination centres close in Mumbai as India posts another record rise in cases

All vaccination centres in India's financial capital of Mumbai have been shut for three days due to a shortage of vaccines, authorities said, as the country posted another record daily rise in coronavirus cases.

India reported 386,452 news cases, while deaths from Covid-19 jumped by 3,498 over the last 24 hours, according to health ministry data.

However, medical experts believe actual Covid-19 numbers in the world's second-most populous nation may be five to 10 times greater than the official tally.

India has added about 7.7 million cases since the end of February, when its second wave picked up steam, according to a Reuters tally. In contrast, it took India nearly six months to add the previous 7.7 million cases.

The country is in deep crisis, with hospitals and morgues overwhelmed, medicines and oxygen in short supply and strict curbs on movement in its biggest cities.

US aid arrives in India as cases explode

The first US emergency aid to India has arrived as the country battles a devastating surge in Covid-19 cases which has overwhelmed hospitals and crematoriums.

A US Super Galaxy military transporter carrying more than 400 oxygen cylinders, other hospital equipment and nearly one million rapid coronavirus tests landed at New Delhi's international airport early Friday.

The delivery, which flew in from the Travis military base in California, followed talks this week between US President Joe Biden and India's Prime Minister Narendra Modi.

US officials said other special flights, which will also bring equipment donated by companies and individuals, are set to continue into next week.

More than 40 countries have committed to sending vital medical aid, particularly oxygen supplies, Foreign Secretary Harsh Vardhan Shringla told reporters earlier on  Thursday.

Edinburgh Castle reopens as Scottish Covid rules ease

Heritage sites reopen across Scotland for the first time this year and after the longest closure since World War II, as coronavirus restrictions are gradually eased.

Edinburgh Castle is one of more than 20 ticketed venues and over 200 free attractions run by Historic Environment Scotland (HES) to welcome back visitors.

HES chief executive Alex Paterson said daily visitor numbers to the ancient stronghold and former royal residence will be well below pre-pandemic highs of 10,000.

But he hopes up to 1,200 people will come every day.

Since the start of the coronavirus outbreak, 7,659 people have died after testing positive for Covid-19 in Scotland – a fraction of the more than 127,000 people who have lost their lives in the UK overall.

Pfizer begins exporting US made  shots abroad, starting with Mexico – source

Pfizer Inc's shipment of Covid-19 vaccine to Mexico this week includes doses made in its US plant, the first of what are expected to be ongoing exports of its shots from the United States, a source familiar with the matter told Reuters.

The vaccine shipment, produced at Pfizer's Kalamazoo, Michigan plant, marks the first time the drugmaker has delivered abroad from US facilities after a Trump-era restriction on dose exports expired at the end of March, the source said.

Canada's largest provinces to soon offer Covid vaccines to all adults

The two Canadian provinces hardest-hit by the coronavirus pandemic, Ontario and Quebec, will make Covid vaccines available to all adults starting in May, officials said.

The health ministers for the provinces, which account for almost two-thirds of the country's population, said age eligibility for jabs would be lowered incrementally.

In Quebec that means eligibility for those 18 years and older by mid-May, with Ontario following a week later.

A ramp up of shipments to the provinces would allow authorities to "accelerate our vaccine rollout and get more shots into arms," Ontario Health Minister Christine Elliott said.
