Chile's world-leading vaccine rollout fails to halt spread of Covid
Chile’s fast vaccine rollout coincides with a spike in cases despite a quarter of the population having had one jab – but is China’s 50% effective CoronaVacvaccine to balme?
- Almost a third of Chile’s population has already been given at least one dose
- However, on Thursday the government put 80 percent of people into lockdown
- With new virus variants, believed to be more contagious, spreading across the continent, cases have been soaring in Chile despite its vaccination drive
- Thursday saw 7,000 new cases in 24 hours, the second highest daily record
- The bulk of doses given in Chile have been China’s CoronaVac vaccinations
- Two doses of CoronaVac only offers 50 percent protection against Covid-19
Chile’s world-leading coronavirus vaccination rollout is failing to halt the spread of Covid-19 as the majority of the country goes into lockdown, with many blaming the use of China’s CoronaVac jabs.
By Thursday the narrow South American nation, hemmed in by the Andes mountains and the Pacific ocean, had given more than six million people – almost a third of its population – a single dose and 3.1 million both doses, including most over-70s.
And yet that same day, the government put more than 80 percent of the country’s 19 million people into lockdown.
With new virus variants, believed to be more contagious, spreading across the continent, cases have been soaring in Chile despite its vaccination drive.
On Thursday it passed 7,000 new cases in the previous 24 hours: the second highest daily figure recorded.
By comparison, the UK – which has so far vaccinated a similar percentage of its population with a combination of the Pfizer/BioNTech and the Oxford/AstraZeneca vaccines – has seen infections drop to a rate not seen since September.

Chile has been using China’s CoronaVac vaccine and the Pfizer/BioNTech, and as of March 25, had administered 49.26 doses of the vaccine per 100 people, while the UK had administered 47.62 of its vaccine doses per 100 people.
But as of March 26 in Chile, there was a seven-day rolling average of 330.82 new coronavirus cases per million people. In the UK, the rate was just 84.08 per million.
‘They are phenomena that run on totally different tracks,’ Darwin Acuna, the president of Chile’s society of intensive medicine, told AFP about the seeming disconnect between high vaccination and contagion rates in the country.
President Sebastian Pinera has urged the country to make ‘a last effort’ and authorities expect the vaccination push to start bearing fruit next month.
Health Minister Enrique Paris said the lockdown ‘is tough but necessary,’ particularly in the Santiago metropolitan area – the most populous in Chile.
The country has recorded more than 950,000 infections and over 22,500 deaths from Covid-19.

Chile began vaccinating health care workers on December 24 and from February 3 it started with the general population, initially the over 90s.
This came after it signed an agreement to purchase 20 million doses of China’s CoronaVac vaccine, which was approved for emergency use on January 20.
So far, the bulk of doses administered have been CoronaVac, which only offers 50 percent protection against Covid-19, meaning for every 100 people vaccinated with two doses of CoronaVac, 50 remain at risk of infection.
While the vaccine will reduce the intensity of symptoms and therefore considerably reduce the risk of hospitalisation for the most series of cases, vaccinated individuals may still spread the virus.
The European Union and other countries, such as the UK and the US, have not approved CoronaVac as it has not been proven to be sufficiently effective.

The use of CoronaVac, combined with a general relaxation of attitudes in the country due to the vaccination campaign and summer holidays, as well as the arrival of new virus variants, has pushed a new wave of infections.
‘You cannot yet see the effect of the vaccine on the most at-risk people, because for the most at-risk people they have only just had the second dose,’ said Acuna.
He expects to see ‘a real effect on the requirement of ICU beds for the most at-risk people’ in mid April.
Health care authorities say they have noticed a difference in the identity of those occupying ICU beds since the first wave of the pandemic: patients are younger and sicker.
‘It seems to be more aggressive than last year. There are patients who go straight to ICU’ and on oxygen, Hector Ugarte, chief doctor at the adult critical patient unit in a hospital in the coastal city Coquimbo, told AFP.
The ages of those needing hospital treatment has fallen ‘enormously,’ said the ministry of health – because the young ‘haven’t been careful.’
On Thursday, Chile’s government put more than 80 percent of the country’s 19 million people into lockdown. This comes despite having given more than six million people a single dose and 3.1 million both doses, including most over-70s. That’s around a third of its population
On Thursday, authorities said they had discovered 45 cases of the Brazilian variant of the novel coronavirus, having already detected the British variant in February.
ICU beds are running at 95 percent occupancy, even in places like Coquimbo, 460 kilometers to the north of Santiago.
Before March 2020 it had eight ICU beds, but there are now 38 and this week 46 people required hospital treatment for Covid-19.
The government’s goal is to immunize 15 million people by June 30, achieving coveted ‘herd immunity,’ when a sufficiently large proportion of the population is resistant to a pathogen that it has nowhere to spread.
By Thursday, authorities had given almost 6.1 million people a first dose of either the Chinese CoronaVac or Pfizer shots.
Teachers, firefighters, the chronically ill, journalists, public sector workers, pharmacy staff and telecommunications employees have already been given a first dose. Most health care workers and old people have had two.
With new virus variants, believed to be more contagious, spreading across the continent, cases have been soaring in Chile despite its vaccination drive.

Despite the high infection rates, there is much optimism.
At a retirement home in the south of Chile where residents and personnel received a first vaccine dose in the opening week of February, a subsequent outbreak of coronavirus in the facility infected 70 people. The only death was a resident who hadn’t been vaccinated.
There is much hope, too, in hospitals.
Ugarte said that during the worst stages of the pandemic last year, the Coquimbo hospital was seeing between 150 and 170 of its 1,700-strong workforce infected with Covid-19.
‘Now, with 80 percent of the staff having been fully vaccinated for a few weeks, there is one!’ he added, calling it ‘the first great demonstration’ of the vaccine’s impact.
