India's new Covid-19 rules aim to free up resources but carry risksNEW DELHI - India has eased its Covid-19 rules on testing, quarantine and hospital admissions in a bid to free up resources for its neediest people, a strategy hailed by experts even though it carries the risk of a heavy undercount of infections and deaths. The moves will offer a breathing space for healthcare facilities, often overstretched in a far-flung...

A late-stage human trial involving 13,000 participants was registered on Clinicaltrials.gov last month. People above 65 were already eligible to get their booster shot five months after the second. Reuters CanSino's inhaled Covid-19 vaccine booster induces a higher level of immune response for those vaccinated with two Sinovac shots than a third dose of the Sinovac vaccine, a team of Chinese researchers has found. But amid concerns about what it called the"rapid spread" of the Omicron coronavirus variant in many countries, the Government in December froze new sales of VTL bus and flight tickets until Jan 20 . Study participants who received the CanSino booster showed "much stronger neutralising antibody responses" - at nearly seven to 11 times higher than that of a three-dose regimen of the Sinovac shot - according to the study of 420 people. A number of other countries, including Britain, Denmark and France, have already reduced the interval between the second and third shots of the vaccine for at least some sections of their populations, sometimes to as little as three months. The study has not been peer-reviewed. "Contact-tracing has been the most resource-intensive activity since the pandemic began," said Sanjay K.

The results indicated "a potential boost strategy" for people primed with inactivated Covid-19 vaccines, said the team, which included scientists from the Jiangsu provincial centre for disease control and prevention, the Chinese military's top epidemiologist and virologist Chen Wei and CanSino Biologics employees. The regions should not have to stand idle with unused capacity," Health Agency Chief Epidemiologist Anders Tegnell said in a statement.

With SIA's latest announcement, elite miles earned by KrisFlyer Elite members in the year prior will be credited back to their accounts after the extension. They posted the results on the platform Preprints with The Lancet last week. Tianjin-based CanSino said the needle free, non-invasive treatment aimed to provide quick, regular and mass-scale protection with easy administration. Sweden stood out early in the pandemic by opting against lockdowns, instead focusing on a mostly voluntary strategy based on social distancing and good hygiene. [embed]https://www. Miles that expire this year will be automatically extended six months at a time.youtube.. Four Indian epidemiologists echoed Rai's view, saying it was better to monitor the numbers of those in hospital, rather than infections, while targeting crowded spaces such as workplaces, dormitories and barracks with rapid testing.

Beijing has yet to approve heterologous vaccination, or administering a different vaccine to the original regimen. Rewards earned from the PPS Rewards and KrisFlyer Milestone Rewards that are due to expire this year will be extended to Dec 31, it added. If approved, the CanSino Covid-19 vaccine is the most likely product to be used because it is the only non-inactivated Covid-19 vaccine approved for general launch in the country, a prerequisite for mixing and matching vaccines. But the product will need to go through clinical trials for approval. A late-stage human trial involving 13,000 participants was registered on the ClinicalTrials. "Extending the membership statuses, as well as continual enhancement of the KrisFlyer programme, provides our members with more recognition and programme benefits. It would also affect the tracking of Covid-19 deaths, an effort Mukherjee said was "already highly imperfect and under-reported".

gov database last month. The company has not estimated its annual product capacity, however it expects the smaller amount required for inhaled doses than the same dose via injection to allow its product to go further. The WHO has suggested that countries using inactivated shots approved by the agency for the first dose then use mRNA or vectored vaccines as part of a two-dose regimen or as a booster for better protection. Inactivated jabs use dead material from the virus to trigger the immune system, while CanSino’s vaccine uses an adenoviral vector to deliver a virus antigen and trigger an immune response.

There was no shortage of test kits, with thousands of people having bought home test kits in the past week, ICMR chief Balram Bhargava said on Wednesday, but did not say if rural areas were as well supplied as urban areas.

But inhaled vaccines imitate natural infection by the virus and target mucosal surfaces – the nose, throat and lungs, the point of entry for pathogens – to induce a localised immune response. The Chinese team found fewer cases of adverse reactions in the inhaled booster groups, which reported reactions such as fatigue, headache and fever. Some people said they had a dry mouth and their throat swelled. South Asian nations with less than half their people fully vaccinated, such as India, run a greater risk of severe illness that requires hospital stays, the International Federation of Red Cross and Red Crescent Societies said.

The study showed that the inhaled booster had a high neutralising capability against the Delta variant – about three times the WHO international standard – while a Sinovac booster was 20 per cent lower than the benchmark. When compared to a third dose of Sinovac, the CanSino booster showed 18-24 times higher cross-neutralising capability against Delta 28 days after the booster, according to the study.
