Covid: When will it be over and we can do this once again? By James Gallagher
Health and science correspondent Published period 31 October
It’s fair to state the entire world is sick to the back teeth of Covid.
A miserable year of not seeing friends and family, weddings cancelled, children missing school, freedoms curtailed, professions ended, a pervading sense of gloom and, regretfully, lots of lives lost.
So when can we expect to return to normal? Do we just have to stick out the winter, before Health Secretary Matt Hancock’s “cavalry” – a vaccine, mass screening, better treatments – arrives, and whatever is great?
Or will Covid be with us for years, even years, to come?
” We may be back to some semblance of normality by summertime time next year,” states Prof Julian Hiscox, from the University of Liverpool. “However we won’t be ‘back to 2019’ for 5 years,” he anticipates.
Some scientists think that to handle the virus, our way of living may need to change permanently.
Our last location
If we could avoid ahead a number of years, the mainly widely held view is the infection will still be around – as what’s called an endemic infection.
However that is not to state life will be the exact same as it is now. We ought to have reached a brand-new relationship with the virus where it is substantially less disruptive to our lives. This follows the pattern of previous pandemics.
A vaccine or multiple infections across a lifetime may offer adequate resistance to stop the infection being as lethal.
” This will calm down over years,” states Prof Mark Woolhouse, from the University of Edinburgh. “The problem is what takes place over those decades. I don’t see a route that isn’t agonizing in one way or another.”

The next couple of months
First, we have to make it through winter and the expectation is it will be rough.
Winter season is party time for respiratory infections anyway, as we spend more time indoors and the cool temperature levels help viruses make it through.
The government is firefighting a virus that will spread quickly if constraints are relieved too much. The UK has already gone from an extremely peaceful summer season to averaging more than 22,000 cases a day. The virus is currently spreading four times faster than the federal government’s worst-case situation which predicted a second wave could be more lethal than the very first.
Rather what Christmas is going to be like is still difficult to call.
Optimism for spring
Spring is most likely to bring three enhancements:
Better weather, allowing people to spend more time outdoors where it is harder for the infection to spread
Increased resistance levels, after more people have actually been infected over winter
Vaccination – we must have begun rolling this out
” I believe the summer season we have actually just had supplies hope that cases will lower, particularly as a lot more people will have had Covid,” says Prof Christina Pagel, from University College London. “We’re not even in this winter season yet, that’s what’s depressing.”
She is “pretty sure” we’re heading for another lockdown.
” If as much as 20% of people had Covid, it would slow things down and we ought to see a huge drop-off, even if there isn’t a vaccine.”
University of Edinburgh I don’t think it will settle at all in the next 18 months
However, there is uncertainty here. The virus had the ability to spread with ease last spring and cases, while staying low, did begin increasing again over the summertime.
” A third wave is certainly possible,” says Prof Woolhouse. “And if neither the 2nd nor the 3rd waves are anything like huge adequate to cause herd resistance, and we do not have a vaccine, then a 4th wave is possible.
” I don’t think it will settle at all in the next 18 months.”
The very first vaccines are not likely to be perfect
It is important to be realistic about what a vaccine could achieve next year. Vaccines paired with better treatments, as I wrote as we went into lockdown, stay the one real exit method.
There are 11 vaccines worldwide that remain in the final stages of screening. We are waiting for results to understand how effective they are, what type of security they provide and for how long that might last.
Vaccines for other illness vary. Some stop you catching the infection, others simply make the disease less extreme and not everyone responds in the same way. Members of the government’s clinical advisory group want to get data quickly on how a Covid vaccine carries out.
But we need to not anticipate a magic bullet.
Prof Hiscox is “reasonably positive” the first generation of vaccines will keep some people out of healthcare facility, but “will not always” stop people from capturing and spreading the infection. And he alerts that some of the people most susceptible to Covid, such as the elderly, may get the least security from a vaccine.
For Prof Woolhouse, a vaccine “would clearly be a game-changer”. But the history of medical research shows it is “unwise” to count on it arriving on time. Even then he is “anxious about the logistics” of vaccinating countless people. A vaccine will cause some “actually tough decisions”, he says, about raising constraints when people might not be completely secured.
Normality will still require time
We are currently closer to normal than we were in lockdown – schools are open and, with the exception of Wales, where there is a two-week “firebreak”, we are not being told to remain at home.
Some degree of social distancing is most likely to continue even with a vaccine next year, says Prof Hiscox, but it will be “less strict”. He also thinks at-risk groups might still require to “shelter” themselves, or take extra preventative measures, since of uncertainty about the amount of security.
” What you might not be able to do is be an 18-year-old back from university who goes and hugs granny who is 85,” he states.
However he cautions that going back to normality will require a vaccine that both stops individuals getting ill and avoids them spreading out the infection. That, he says, will take 5 years.
” For many people,” states Prof Woolhouse, “I suspect life has changed to some degree permanently, I do not believe there is a returning.
” There is a ‘new typical’.”.
In his positive view, that implies there’s sufficient immunity to make transmission rates low, so there is no “crisis”, however we would still require to keep using face coverings, be extra careful with hand health and socially distance.
” And we stay used to that for years or years until it actually does settle. The 2nd wave is absolutely not completion of it.”.
For Prof Pagel, it is “possible Covid might become like an annual influenza, more people will be fine than now”. But that would make winter tougher than we’re used to, she says, and would stack pressure on medical facilities which would be essentially facing a “double influenza season”.
