BREAKING NEWS | ‘Great Day For Humanity’: Pfizer Says COVID-19 Vaccine Over 90% Effective

MILAN  – – Pfizer said on Monday its experimental COVID-19 vaccine was more than 90% effective,  a major victory in the fight against a pandemic that has killed more than a million people, battered the world’s economy and upended daily life.

Pfizer and German partner BioTech  are the first drugmakers to release successful data from a large – scale clinical trial of a coronavirus vaccine. The companies said they have so far found no serious safety concerns and expect to seek U.S. authorization this month for emergency use of the vaccine.

Health experts said Pfizer’s results were positive for all COVID-19 vaccines currently in development since they show the shots are going after the right target and are a proof of concept that the disease can be halted with vaccination.

‘Today is a great day for science and humanity’, Albert Bourla, Pfizer’s chairman and chief executive, said.

We are reaching this critical milestone in our vaccine development program at a time when the world needs it most with infection rates setting new records, hospitals nearing over-capacity and economics struggling to reopen’.

If Pfizer’s vaccine is authorized, the number of doses will initially be limited and many questions remain, including how long the vaccine will provide protection.

BioNTech Chief Ugur Sahin told Reuters he was optimistic the immunization effect of the vaccine would last for a year although that was not certain yet.

‘This news made me smile from ear to ear. It is a relief to see such positive results on this vaccine and bodes will for COVID-19 vaccines in general’, said Peter Horby, professor of emerging infectious diseases at the University of Oxford.

MARKETS SURGE

The prospect of a vaccine electrified world markets with S&P 500 future hitting a record high and tourism and travel shares surging. Shares of companies that have benefited from pandemic – related lockdown dropped including conferencing platform Zoom Vide Communication which was down 12% in premarket trading.

Pfizer shares were indicated 14.2 higher in pre-market trading in New York, while BioNTech’s stock was up nearly 23% in Frankfurt.

‘Light at the end of the tunnel. Let’s just hope the vaccine deniers won’t get in the way, but 2021 just got a lot brighter’, said Neil Wilson, chief market analyst at Markets.com.

Shares of other vaccine developers in the final stage of testing also rose with Johnson & Johnson up 4% in pre-market trading and Moderna 7.4% stronger. Britain’s AstraZeneca was down 0.5%.

‘The efficacy data are really impressive. This is better than most of us anticipated’, said William Schaffner, infectious disease expert at Vanderbilt University School of Medicine, Nashville, Tennessee. ‘The study isn’t completed yet, but nonetheless the daya look very solid’.

U.S. President Donald Trump welcomed the test results, and the market boost: ‘STOCK MARKET UP BID, VACCINE COMING SOON. REPORT 90% EFFECTIVE. SUCH GREAT NEWS!’ he said on Twitter.

President – elected Joe Biden said the news was excellent but did not change the fact that face masks, social distancing and other health measures would be needed well into next year.

1.3 BILLION DOSES

Pfizer expects to seek broad U.S. authorization for emergency use of the vaccine for people aged 16 to 85. To do so, it will need two months of safety data from about half the study’s 44,000 participants, which is expected late this month.

Pfizer and BioNTech have a $1.95 billion contract with the U.S. government to deliver 100 million vaccine does beginning this year. They have also reached supply agreements with the European Union, the United Kingdom, Canada and Japan.

To save time, the companies begun manufacturing the vaccine before they knew whether it would be effective. They now expect to produce up to 50 million doses, or enough to protect 25 million people this year.

Pfizer said it expects to produce up to 1.3 billion doses of the vaccine in 2021.

The U.S. pharmaceutical giant said the interim analysis was conducted after 94 participants in the trial development COVID-19, examining how many of them had received the vaccine versus a placebo.

The company did not break down exactly how many of those who fell ill received the vaccine. Still, over 90% effectiveness implies that no more than 8 of the 94 people who caught COVID-19 had been given the vaccine, which was administered in two shots about three weeks apart.

The efficacy rate is well above the 50% effectiveness required by the U.S. Food and Drug Administration for a coronavirus vaccine.

MORE DATA NEEDED

To confirm the efficacy rate, Pfizer said it would continue the trial until there are 164 COVID-19 cases among participants. Bourla told CNBC on Monday that based on rising infection rates, the trial could be completed before the end of November.

The data gave yet to be peer-reviewed or published in a medical journal. Pfizer said it would do so once it has results from the entire trial.

‘These are interesting first signals, but again they are only communicated in press release’, said Marylyn Addo, head of tropical medicine at the University Medical Center Hamburg – Eppendorf in Germany.

‘Primary data are not yet available and a peer – reviewed publication is still pending. We still have to wait for the exact data before we can make a final assessment’.

The global race for  a vaccine has seen wealthier countries forge multibillion dollar supply deals with drugmakers like Pfizer, AstraZeneca Plc and John & Johnson, raising questions over when middle income and poorer nations will get access to inoculations.
