When will we have a Covid-19 vaccine?

By Unknown

When will an antidote against Covid-19 finally become widely available? The answer to this question may eventually be found this month as a handful of coronavirus vaccine candidates near the end of late stage clinical trials. At least two vaccine frontrunners — Pfizer and Moderna Inc — are set to release late-stage and Phase 2 results this month.

While experts have said vaccines were likely to reach the general public in the March-April 2021, drugmakers have been more ambitious with their calculations, with some firms like Moderna Inc eyeing the emergency-use authorisation route to launch their shots by year end. In fact, Pfizer may also file for US FDA approval of its vaccine this month itself, Bloomberg reported.


There are 182 vaccine candidates in pre-clinical or clinical trials across the world. Of these, 36 are in clinical trials and nine in final states of human trials. In India, where two vaccines are in phase II trials and the one by Oxford in phase III, the Union Health Ministry has said it was expecting supplies to be available from January next year.

US biotechnology company Moderna, whose mRNA-1273 vaccine is undergoing phase-3 clinical trials in the United States on 30,000 participants, has said it might seek emergency-use authorisation (EUA) after November 25 once it had enough safety data. During public health emergencies, drug regulators allow the emergency-use authorisation of unapproved medical products or treatments.


“November 25 is the time we will have enough safety data to be able to put into an emergency-use authorization file that we would send to the FDA,” Moderna CEO Stephane Bancel told Forbes. However, he said approval wouldn’t be expected until the late first quarter or early second quarter of 2021.

US biotechnology company Moderna, whose mRNA-1273 vaccine is undergoing phase-3 clinical trials in the United States on 30,000 participants, has said it might seek emergency-use authorisation (EUA) after November 25 once it had enough safety data.

Recent trial results: Recently, results of phase 1 trials of the mRNA-1273 vaccine showed that it was well-tolerated and generated a strong immune response in older adults (participants over 55 years of age).

The study, published in the New England Journal of Medicine, found that the immune response to the vaccine seen in older volunteers was comparable to that seen in younger age groups. Moreover, the blood of vaccinated volunteers contained robust binding and neutralising antibodies against SARS-CoV-2.

Increased risks of drop out for women and girls : CoronaVirus Updates

By Unknown
The total number of children not returning to their education after the school closures is likely to be significant. The pandemic also risks jeopardizing some of the gains made since 2001 in re-building women and girls’ education following the Taliban regime.  The COVID-19 pandemic is creating additional barriers due to risks—and students’ and parents’ anxiety about risks—associated with children returning to classrooms that are cramped, with no capacity for distancing, often cold, damp and poorly ventilated during the country’s severe winters, and have no or poor hygiene and clean water facilities. The COVID-19 pandemic is likely to drive many women and girls out of education permanently. School closures due to COVID-19, resulting increases in caregiving responsibilities for women and girls, and increases in poverty and unemployment will all make it harder for women and girls to study.  These factors combine in harmful ways with pre-existing discriminatory gender norms, o...

Australia's Victoria state to ease COVID-19 restrictions as cases slow

By Unknown
Victoria, Australia's second most populous state and the epicentre of the country's COVID-19 outbreak, will accelerate the easing of social distancing restrictions as infections slow to fewer than 20 cases a day, its premier said on Sunday. Victoria, which reported 16 COVID-19 cases in the past 24 hours, has placed nearly 5 million residents of its capital Melbourne under one of the world's most stringent lockdowns since early August. With cases well below the record one-day high of more than 700 cases reported in August, state Premier Daniel Andrews said some curbs, including a night curfew, will be removed almost immediately. The remaining curbs could be relaxed earlier, with restrictions eased when case numbers hit certain triggers. Victoria state previously said most restrictions would remain in place until the end of November. "We are ahead of schedule, we have made more progress than we hoped to make at this point in time," Andrews told reporters in Melbou...
