Study: Chinese vaccine offers poor protection from Covid-19 among the elderly

BUDAPEST: A new study suggests that a Sinopharm vaccine offers poor protection from Covid-19 among the elderly, raising questions for dozens of countries that have given the Chinese company's shots to their most vulnerable populations. A survey of blood samples taken from 450 people in Hungary at least two weeks after their second Sinopharm dose found that 90% under 50 years old developed protective antibodies. But the percentage declined with age, and 50% of those over 80 had none. The study by two Hungarian researchers was posted online this week but not yet reviewed by other scientists. Three outside experts…

Covid Delta variant to dominate within months: WHO

Covid Delta variant to dominate within months: WHO

GENEVA: The highly contagious Delta variant of Covid-19 is expected to become the dominant strain of the virus over the coming months, the world health organization said on Wednesday. Delta, which was first detected in India, has now been recorded in 124 territories - 13 more than last week - and already accounts for more than three-quarters of sequenced specimens in many major countries, the WHO said. "It is expected that it will rapidly out-compete other variants and become the dominant circulating lineage over the coming months," the UN health agency said in its weekly epidemiological update. Of the three…

WHO warns of ‘early stages’ of Covid-19 third wave amid Delta variant surge

GENEVA: World Health Organisation (WHO) chief Tedros Adhanom Ghebreyesus on Thursday warned the world about the 'early stages' of Covid-19 third wave amid Delta surge. "Unfortunately...we are now in the early stages of a third wave", he said. On Wednesday, the head of WHO said that Delta variant's spread, along with increased social mobility and the inconsistent use of proven public health measures, is driving an increase in both case numbers and deaths. Recalling the sustained decline in Covid-19 cases and deaths that was being driven, in recent months, by increasing vaccination rates in Europe and North America, he sounded…

Need more data for decision on booster shots, US tells Pfizer

NEW YORK: US health officials, after meeting with vaccine maker Pfizer, reiterated on Monday that Americans who have been fully vaccinated do not need to get a booster shot, a spokesperson for the Health and Human Services Department said. Pfizer said last week it planned to ask US regulators to authorise a booster dose of its Covid vaccine, based on evidence of greater risk of infection six months after inoculation and the spread of the contagious Delta variant. HHS officials had a briefing from Pfizer on Monday regarding their latest, preliminary data on vaccinations and will continue to discuss when…

Spread of Covid-19’s Delta variant will substantially up cases, put pressure on healthcare: WHO

UNITED NATIONS/GENEVA: The increased transmissibility associated with the Covid-19's Delta variant is likely to substantially increase cases and put greater pressure on healthcare systems, particularly in the contexts of low vaccine coverage, WHO has warned. In its Covid-19 Weekly Epidemiological Update released on Tuesday, the World Health Organisation said that an overall rise in Covid-19 cases due to the Delta variant is reported across all WHO regions. As of July 13, at least 111 countries, territories and areas have reported detection of the Delta variant, and this is expected to continue to increase, becoming the dominant variant globally in the…

Thailand defends Covid vaccine ‘mix-and-match’ after WHO warning

Thailand defends Covid vaccine ‘mix-and-match’ after WHO warning

BANGKOK: Thailand on Tuesday defended mixing two different Covid-19 vaccines to battle a surge in infections, after the WHO's top scientist warned it was a "dangerous trend" not backed by evidence. The kingdom is struggling to contain its latest outbreak fuelled by the highly contagious Delta variant, with cases and deaths skyrocketing and the healthcare system stretched thin. Authorities said they will mix a first dose of the Chinese-made Sinovac jab with a second dose of AstraZeneca to try and achieve a "booster" effect in six weeks instead of 12. Thailand's chief virologist Yong Poovorawan said this would be possible…

Immunized but banned: EU says not all Covid vaccines equal

LONDON: After Dr. Ifeanyi Nsofor and his wife received two doses of AstraZeneca's coronavirus vaccine in Nigeria, they assumed they would be free to travel this summer to a European destination of their choice. They were wrong. The couple and millions of other people who have been vaccinated through a UN -backed effort - could find themselves barred from entering many European and other countries because those nations don't recognize the Indian-made version of the vaccine for travel. Although AstraZeneca vaccine produced in Europe has been authorized by the continent's drug regulatory agency, the same shot manufactured in India hasn't…

Delta variant ripping around the world at a scorching pace, driving new spike in cases, death: WHO

UNITED NATIONS/GENEVA: The Delta variant is ripping around the world at a scorching pace, driving a new spike in cases and deaths, WHO chief Tedros Adhanom Ghebreyesus has said, warning that the variant, now in over 104 countries, is expected to soon be the dominant Covid-19 strain circulating worldwide. Addressing a press briefing on Monday, he said that last week marked the fourth consecutive week of increasing cases of Covid-19 globally, with increases recorded in all but one of WHO's six regions, adding with concern that after 10 weeks of declines, deaths are increasing again. “The Delta variant is ripping…

WHO says countries should not order Covid-19 boosters while others still need vaccines

GENEVA: Rich countries should not be ordering booster shots for their vaccinated populations while other countries have yet to receive Covid-19 vaccines, the World Health Organization said on Monday. WHO Director-General Tedros Adhanom Ghebreyesus said deaths were again rising from the Covid-19 pandemic, the Delta variant was becoming dominant, and many countries had yet to receive enough vaccine doses to protect their health workers. "The Delta variant is ripping around the world at a scorching pace, driving a new spike in Covid-19 cases and death," Tedros told a briefing, noting that the highly contagious variant, first detected in India, had…
