Delaying second covid vaccine dose may prevent deaths under certain conditions
Delay strategy, at least for people under 65, could reduce deaths by up to 20%, say researchers
Delaying the second dose of covid-19 vaccines, at least for people aged under 65, could result in up to 20% lower mortality, but only under certain conditions, finds a US study published by The BMJ today.
These conditions include a one dose vaccine effectiveness (efficacy) of 80% or higher and vaccination rates of 0.1% to 0.3% of the population per day. If these conditions apply, the researchers say the strategy could prevent between 47 and 26 deaths per 100,000 people, respectively.

Covid-19 travel plan will let new variants into UK
Reduce air travel not only because of covid-19, but also because of the detrimental impact that this has on our climate, say researchers
The government’s covid-19 travel plan will let new variants into the UK, warn experts in The BMJ today.
Virologists Jangu Banatvala and Deenan Pillay urge caution over plans to implement a traffic light system, permitting international travel to resume dependent upon the covid-19 status of destination countries.
And they warn that the aviation industry’s current enthusiasm to resume international air travel and overseas holidays, and to expand airports needs to be checked, saying “it flies in the face of the twin needs to control international virus transmission, and tackle the climate emergency and environmental degradation.”
No difference between those who did and didn’t take these drugs for 1-2 years
Long term use of prescription meds for insomnia doesn’t seem to improve disturbed sleep in middle-aged women, suggests research published in the online journal BMJ Open.
There was no difference in sleep quality or duration between those who did and didn’t take these meds for 1 to 2 years, the findings show.
Disturbed sleep–difficulty falling and/or staying asleep and waking early–is common. An estimated 9 million adults in the US alone say they take prescription meds to try and get a good night’s sleep.
