The Latest: Indian states warn of COVID-19 vaccine shortages

Health
NEW DELHI — Multiple Indian states are warning the federal government of COVID-19 vaccine shortages as another spike in cases threatens to overrun the country and its already-feeble medical infrastructure.Authorities in New Delhi and in Punjab and Rajasthan states said Saturday that they would not be able to continue vaccinations in the coming days unless stocks were replenished. Earlier this week, western Maharashtra state, the epicenter of the country’s outbreak, closed some vaccination centers and turned people away due to inadequate vaccine supplies.Indian Health Minister Harsh Vardhan has said the country has enough doses and urged state governments to put an end to “fearmongering.”India, a major vaccine manufacturer, has so far administered 97 million shots but is facing major supply

Covid: UK vaccine rollout ‘breaking link’ between infections and death

Health
Getty ImagesIncreasingly strong evidence shows that the UK's vaccination programme is breaking the link between Covid-19 cases and deaths, scientists tracking the epidemic have said. A study found infections had fallen by roughly two-thirds since February, before beginning to level off.This is probably because people are beginning to mix more - but deaths have not followed the same pattern.This was not the case before January, when the vaccine rollout began. The research, commissioned by the government and run by Imperial College London, is based on swabs taken from 140,000 people selected to represent England's population.Of that group, who were tested for the virus between 11 and 30 March, 227 had a positive result, giving a rate of 0.2%, or one in 500 people.But in people over the age o...

Greg Abbott used his executive power Tuesday to ban state government and some private entities from requiring COVID-19 “vaccine passports” to access services, in the latest move from a Republican governor pitting public health campaigns against personal freedom and private choices.According to Abbott's order, state agencies and political subdivisions, and public and private organizations that receive public funding in Texas cannot require people to prove that they have been inoculated against th

Covid-19: Seven UK blood clot deaths after AstraZeneca vaccine

Health
EPASeven people have died from unusual blood clots after getting the Oxford-AstraZeneca vaccine in the UK, the medicines regulator has confirmed to the BBC. In total, 30 people out of 18 million vaccinated by 24 March had these clots.It is still not clear if they are just a coincidence or a genuine side effect of the vaccine.The Medicines and Healthcare Products Regulatory Agency says the benefits continue to outweigh any risk. However, concern has led to other countries including Germany, France, the Netherlands and Canada to restrict the vaccine's use only to older people. The data released by the MHRA on Friday showed 22 cases of cerebral venous sinus thrombosis (CVST) which is a type of blood clot in the brain. These were accompanied by low levels of platelets, which help form blood cl...
New vulnerable sites identified on surface of COVID spike protein that ‘could help future vaccine development’

New vulnerable sites identified on surface of COVID spike protein that ‘could help future vaccine development’

Technology
Scientists have discovered new vulnerable sites on the surface of the COVID-19 spike protein for antibodies which could help in the development of vaccines.Coronavirus is surrounded by spike proteins that it uses to enter and infect human cells. COVID vaccines work by teaching the immune system to make antibodies to the spike protein. Researchers from the Max Planck Institute of Biophysics in Frankfurt, Germany, have developed a detailed model of the spike protein to identify potential target sites on its surface for the antibodies.They said previous models have not shown the flexibility of the spike protein or the movements of the protective glycans - which they describe as chains of sugar molecules - that coat it. ...
