time to answer more of your questions now i have it to a science correspondent eric williams. the astra zeneca vaccine is around 70 percent effective is that really enough for it to be any good. i've received several different versions of this questions the issue is obviously one that's causing some confusion i think what's driving it is a similarity between 2 very different factors that are expressed as a similar percentage 70 percent and the 1st of those factors is an epidemiological prediction that comes up a lot it's what's now considered to be kind of low ball estimate of the number of people needed to achieve what we call herd immunity that very theoretical moment when enough people are immune to covert 19 through vaccination or having had the disease to allow us to get on top of transmission that 70 percent however is different from the 2nd factor the roughly 70 percent effectiveness claimed by the astra zeneca vaccine that 70 percent basically tells you that if a large number of people receive the vaccine and an equally large number don't and then you wait a few months

let me put you in the capable hands of my colleagues eric williams now to look at your questions on the corona virus. i've been vaccinated and feel some side effects and i contagious to others. pretty much all of the vaccines approved so far and various parts of the world are fairly reacted generally which means they often cause mild side effects like painting and swelling at the injection side as well as things like like fatigue or headache or fever or chills or aching joints by by some estimates about 2 thirds of all recipients reports those sorts of effects soon after having a shot they generally disappear within a day or 2 side effects appear to be more common in women than in men and also seem to happen more often in younger recipients then in the elderly but but side effects aren't caused by live virus replicating in your body because the vaccines in use don't actually contain any live virus instead they employ a number of different tricks to pull your immune system into believing you've copped a virus many vaccine platforms work by delivering genetic instructions into your cells

question today in the travel industry from one of our huge abuses saints and scholars a letter to eric williams take care that. is it ethical to insist that the vaccine is mandatory for travel. i'm no expert on ethics but i'd like to explore this anyway as it's rapidly turning into a very big issue decisions are already being made by governments and businesses and universities you name it about whether or not to grant privileges or impose restrictions on things like travel based on vaccination status the 1st point to make i think is that all major health authorities are advising people who can be vaccinated to get backs unaided as a way to protect yourself but also as a way to protect others and and that 2nd part is the real ethical crux by choosing not to get banks unaided you could potentially catch and pass on a deadly disease to other people so seriously simplified and boiled down this question becomes kind of a classic faceoff between an individual's right to choose what's best for them and what expert authorities say is best for all of us. currently complicating the picture is that both i

time to answer more of your questions now to our science correspondent eric williams. how with a pandemic and. only when the entire world is vaccinated. when it comes to predicting the future really your guess is as good as mine but if i did have to hazard one i'd say there are a couple of scenarios to choose from the 1st and least likely in my opinion is that will somehow manage to begin coordinating efforts on a hitherto unheard of scale to stymie new outbreaks before they can spend out of control like they have already in country after country any return to anything like a prepared demick normal at least on a global scale will require speeding up and extending vaccine drives in every corner of the planet now and not later and of course the virus would have to play along by not mutating too quickly or or dramatically so soon imaginable scenario one that a lot of epidemiologists think isn't going to happen. more likely they say is that vaccines won't stop at 19 transmission completely but they will slow it in many places anough to manage the virus like we manage other

time to as a more of your questions now over to our science correspondent eric williams. why aren't injected vaccines manufactured as a single unit instead of having the vaccine in the syringe separate this is a great question one that i've never really actually considered before right now most vaccine manufacturers are are filling and shipping multi-dose vials of vaccine that contain between $5.15 doses on site at the vaccination center or at the doctor's office staff then have to painstakingly draw them into syringes in a complex time consuming series of steps where we're a lot could actually go wrong due to human error and and there are a lot of other issues with the vial system not least that once the seal on one has been broken all of the doses in the bio have to be used quickly leftovers can't just be stuck back in the fridge for use later so so since everyone is getting their own syringe anyway why aren't machines just pretty filling them directly as a single unit instead of putting large batches of doses in vials 1st prefilled single shot syringes are already the

time to answer more of your questions now i have it to a science correspondent eric williams. the astra zeneca vaccine is around 70 percent effective is that really enough for it to be any good. i've received several different versions of this questions so the issue is obviously one that's causing some confusion i think what's driving it is a similarity between 2 very different factors that are expressed as a similar percentage of 70 percent and the 1st of those factors is an epidemiological prediction that comes up a lot it's what's now considered to be kind of low ball estimate of the number of people needed to achieve what we call herd immunity that very theoretical moment when enough people are immune to covert 19 through vaccination or having had the disease to allow us to get on top of transmission that 70 percent however is different from the 2nd factor the roughly 70 percent effectiveness claimed by the astra zeneca vaccine that 70 percent basically tells you that if a large number of people receive the vaccine and an equally large number don't and then you wait a few
