Pfizer now claims its coronavirus jab is 95% effective.. days after Moderna’s breakthrough
Pfizer now says its Covid-19 jab is safe, 95% effective and will be ready for approval by the end of the week… days after Moderna’s breakthrough
- Pfizer and BioNTech say they have now completed a final stage clinical trial of their Covid-19 vaccine
- Final results show it has 95% efficacy, with over 94% even in at-risk elderly people – up from 90% early result
- A second vaccine by Moderna bettered Pfizer’s 90% trial result last week, claiming 94.5% in release this week
- Pfizer says it now has enough safety data to apply for a licence in the US and other countries ‘within days’
- UK has bought 40million doses of Pfizer’s vaccine and could get 10m this year, distributing from December 1
Pfizer and BioNTech today revealed they have finished the final trial of their coronavirus vaccine and can prove it is safe and up to 95 per cent effective at preventing Covid-19.
Their announcement comes just days after rival firm Moderna claimed its own jab was 94.5 per cent effective, and is an improvement on Pfizer’s early estimate that the vaccine was 90 per cent effective.
Pfizer made the newest claim about its vaccine in a statement confirming the third stage of the trial has now been running for long enough that it can submit the required two months’ worth of safety data to regulators, and that it would do so in the US and UK ‘within days’.
Britain has already pre-ordered 40million doses of the vaccine and could be set to get 10m of those next month, with the NHS gearing up to start a major Army-backed operation to get the public protected against the disease from as soon as December 1.
UK drug regulator the MHRA, has been doing a ‘rolling review’ of the vaccine and could, as a result, complete the approval process within days of receiving the company’s application.
Final trial results showed that only eight people out more than 20,000 who got the vaccine caught coronavirus in the study, compared to 162 who were given a fake jab. A total of 10 people got severe Covid-19, one of whom had been given the real vaccine.
An independent safety committee ‘has not reported any serious safety concerns related to the vaccine’ since the final stage trial began in July, Pfizer said. Side effects were limited – the most common was fatigue, which 3.8 per cent of people got, and headaches (2 per cent). The company said side effects were less common in older people and insisted that it did work for over-65s, who are known to be most vulnerable to the disease.
Questions were raised when Moderna announced its results on Monday about whether the UK had hitched its wagon to the wrong project, ordering 40m of Pfizer’s jab – then thought to be 90 per cent effective – but none of Moderna’s.
The updated data from Pfizer and BioNTech should reassure critics but the Government still faces the mammoth task of transporting and storing the jab, which may need expensive specialist freezers and huge supplies of dry ice to keep it at the required -70°C (-94°F). Moderna’s, meanwhile could be kept in normal fridges and freezers at between -20°C (-4°F) and 8°C (46°F).

Pfizer and BioNTech’s vaccine works by using genetic material called RNA from the coronavirus to trick the body into making the ‘spike’ proteins that the virus uses to latch onto cells inside the body, and then training the immune systems to attack the spikes

In other coronavirus developments:
- Christmas get-togethers look set to be given the green light but it will mean living with bolstered lockdown measures before and after the festive period that could jeopardise New Year, officials warned;
- Boris Johnson refused to apologise after a devastating report laid bare the Government’s £18billion rush to source PPE during the coronavirus crisis and claims Conservative cronies were given VIP access to lucrative contracts;
- Testing tsar Baroness Dido Harding revealed that she has been ordered to self-isolate by her own coronavirus contact tracing app;
- One in eight coronavirus cases were placed in the wrong areas between September and November because students’ test results were pinned to their home addresses, it was revealed;
- Immunity to coronavirus lasts at least eight months, according to data that suggests survivors could be protected for years;
- Britons could be required to show QR codes on their phones to prove they have been vaccinated against Covid-19 in order to attend football matches, the theatre and other events, it was suggested.
Pfizer said it had now got the two months of safety data it needed to apply for a vaccine licence from the US’s Food and Drug Administration (FDA).
The drugmaker said the vaccine seemed to work ‘consistently’ well on people across all age groups and ethnicities, which is crucial for protecting elderly and non-white communities, who are most at risk from severe Covid-19. This also means that the vaccine will be useful for countries all over the world and not just Western Europe and the US.
Efficacy in adults over 65 years, who are at particular risk from the virus, was over 94 per cent.
The vaccine, named BNT162, is split into two doses given three weeks apart, with the study measuring results starting 28 days after the first dose of the jab, when immunity is thought to be established.
It is not yet clear how long protection against coronavirus will last for in people who get the vaccine – only the coming months, years and potentially decades of follow-up will confirm this. The study will continue for at least another two years.
BioNTech CEO Ugur Sahin said: ‘We are grateful that the first global trial to reach the final efficacy analysis mark indicates that a high rate of protection against Covid-19 can be achieved very fast after the first dose, underscoring the power of BNT162 in providing early protection.’
The final analysis comes just one week after initial results from the trial showed the vaccine was more than 90 per cent effective.
Moderna on Monday released preliminary data for its vaccine, showing similar effectiveness.
The better-than-expected data from the two vaccines have raised hopes for an end to the pandemic, which has killed more than 1.3million people globally and at least 52,000 in the UK.
However, while some groups such as healthcare workers will be prioritized in the United States for vaccinations this year, it will be months before large-scale rollouts begin.
Pfizer said on Wednesday there had been 170 cases of the disease in its trial of more 43,000 volunteers, of which 162 were observed in the placebo arm and 8 were in the vaccine group.
Ten people developed severe COVID-19, one of whom received the vaccine.
It also said the vaccine was well-tolerated and that side effects were mostly mild to moderate and cleared up quickly.
The only severe adverse event that affected more than 2 per cent of those vaccinated was fatigue, which affected 3.7 per cent of recipients after the second dose. Older adults tended to report fewer and milder solicited adverse events following vaccination.
The results come as the virus is running rampant in the United States, Europe and elsewhere, placing an enormous strain on healthcare systems with record numbers of new cases and hospitalizations.
The approach of winter in the northern hemisphere in tandem with the holiday season is expected to worsen case numbers as people spend more time indoors and get together for family gatherings.
‘With hundreds of thousands of people around the globe infected every day, we urgently need to get a safe and effective vaccine to the world,’ Pfizer CEO Albert Bourla said in a statement.
Pfizer and BioNTech also said they plan to submit the data to other regulatory agencies around the world as well as the United States. They also plan to submit data from the study to a peer-reviewed scientific journal.
Pfizer reiterated it expects to make as many as 50 million vaccine doses this year, enough to protect 25 million people, and then produce up to 1.3 billion doses in 2021.
Of the dozens of drugmakers and research groups racing to develop vaccines against COVID-19, the next data release will likely be from AstraZeneca Plc with the University of Oxford in November or December. Johnson & Johnson says it is on track to deliver data this year.
It comes after Pfizer’s chief executive officer yesterday claimed the company ‘didn’t conspire with anyone’ to delay releasing efficacy results for its Covid-19 vaccine until after the US presidential election.
‘We didn’t conspire with anyone, of course. The election was an artificial line. It may have been important to the president, but it wasn’t for us,’ Albert Bourla said.
Pfizer drew scrutiny after announcing early trial results on November 9, two days after Joe Biden was declared winner of the election — despite previously insisting the results would be known by the end of October.
President Donald Trump raged at the discrepancy, accusing the Food and Drug Administration (FDA) of imposing restrictions to delay the results of the trial.
‘As I have long said, @Pfizer and the others would only announce a Vaccine after the Election, because they didn’t have the courage to do it before,’ he tweeted after the results were published.
‘Likewise, the @US_FDA should have announced it earlier, not for political purposes, but for saving lives!
‘The @US_FDA and the Democrats didn’t want to have me get a Vaccine WIN, prior to the election, so instead it came out five days later – As I’ve said all along!’
Bourla also came under scrutiny after it was revealed that he sold 60 percent of his Pfizer shares on the same day that the trial results were announced.
It was part of a pre-arranged trade that he set up in August, but the timing of the vaccine trial announcement allowed him to cash in on the surge in Pfizer’s share price.
