Home Health Wellness Wellness on January 18, 2022 An Israeli hospital said on January 17 that preliminary research indicates a fourth dose of the coronavirus vaccine provides only limited defense against the Omicron variant that is raging around the world. Sheba Hospital last month began administering a fourth vaccine to more than 270 medical workers — 154 who received a Pfizer-BioNtech vaccine and 120 others who received Moderna's. All had previously been vaccinated three times with the Pfizer-BioNtech vaccine. The clinical trial found that both groups showed an increase in antibodies “slightly higher” than following the third vaccine last year. But it said the increased antibodies did not prevent the spread of Omicron. “Despite increased antibody levels, the fourth vaccine only offers a partial defence against the virus,” said Dr Gili Regev-Yochay, director of the hospital's infection disease unit. “The vaccines, which were … [Read more...] about COVID Vaccine 4th Dose Shows Limited Results With Omicron, Says Study In Israel
When can my child stop using a booster seat
Home Health Health on January 18, 2022 With omicron having rapidly driven up COVID infections, attention is once again focusing on antibodies, and reasonably so. They play a critical role in fighting off viruses and are important for preventing the coronavirus from infecting our cells. This is why some countries have mounted booster campaigns in response to recent COVID surges - to top antibody levels up. But there's a problem. COVID antibodies don't persist that well - hence the desire for boosters. Indeed, while these extra jabs maintain good protection against severe COVID, it's estimated that people receiving a third dose of the Pfizer vaccine will see their protection against developing COVID symptoms (of any degree) drop from 75 per cent to 45 per cent over the ten weeks following their booster. Scientists have questioned whether topping up antibodies, only to see them soon fade away, is sustainable. If we want to … [Read more...] about COVID-19: Why T Cell Vaccines Could Be The Key To Long-Term Immunity
Home Pregnancy parenting Kids Kids on January 18, 2022 Lockdowns during the pandemic aimed to limit the spread of COVID-19 and related deaths. However, these lockdowns also affected how active people were. Children became significantly more sedentary. There is a risk that short term changes in children’s physical activity in reaction to COVID-19 may end up extending beyond the duration of the pandemic. It is very easy for habits to become established, and for a more sedentary and less physically active lifestyle to become normal and ingrained in young people. However, there are ways children can be encouraged to be more active. These include getting the whole family involved in physical activity and building exercise into a routine. Global Trend Research from around the world has examined the extent that COVID-19 restrictions have had on children and their levels of physical activity. Canadian researchers carried out an online … [Read more...] about Children Exercised Less During COVID Lockdown – 4 Tips To get Them Moving Again
Home Health Health on January 16, 2022 A 26-year-old BESCOM lineman, while working Devarabeesanahalli in Bengaluru was accidentally electrocuted and was brought to the Sakra World Hospital Emergency by his colleagues and the police on the morning of 2 December 2022. There was no heartbeat when he arrived at the emergency department. His heart was affected by an abnormal rhythm called Ventricular Fibrillation, where the electrical activity of the heart becomes erratic and uncontrolled, and the heart muscle fails to contract with its usual synchrony effectively stopping the heart. In victims of electrocution, this is could be one of the causes of instant death. When the heart stops the brain is starved of oxygen and there are only minutes left before it begins to undergo irreversible cell death. Survivors of cardiac arrests like this, often land in a vegetative state, especially if CPR was late and the brain was deprived of oxygen for too long. … [Read more...] about What Is Ventricular Fibrillation?

Home Health Health on January 18, 2022 Hydroxychloroquine, the anti-malaria drug controversially touted as a cure for COVID despite a lack of robust evidence, is creating renewed interest as a potential treatment for omicron. The discussion has been sparked by a new study from the University of Glasgow, which is yet to be published in a scientific journal, that looks at how antibodies from vaccines block omicron from entering cells. The researchers conclude, as many others have, that antibodies (the proteins that neutralise the virus) against previous variants or induced by vaccines are less effective against omicron. What's interesting, though, is that the study finds that omicron may have changed the way it enters cells. SARS-CoV-2, the virus that causes COVID, is coated in a lipid bilayer (a thin membrane made of two layers) just like our cells. When the virus enters our cells, the bilayers fuse like oil droplets on the … [Read more...] about Omicron: Is Anti-Malaria Drug Hydroxychloroquine Really Effective Against The COVID Variant?
