Pfizer coronavirus jab has stopped 50% of infections – NOT just symptoms – Israeli study finds

3

Israel is yet to see its infection and death numbers come tumbling down after four weeks of the world’s fastest coronavirus vaccination programme – but studies suggest the jab could eventually slow the rate of contagion by up to 50 per cent. 

While more than 20 per cent of Israel’s population has received an initial dose, infection rates are at their highest ever with more than 8,000 people testing positive per day and a record 1,102 people in hospital with Covid-19. 

But with scientists saying that the vaccine’s protection will typically take a week or two to kick in, Israel is expecting to see new hospitalisations start falling soon. 

Meanwhile, a top official at Israel’s health ministry offered a ray of hope to the rest of the world by announcing initial findings that the vaccine might not only stop symptoms but cut the risk of transmission as well. 

Trials of the Pfizer/BioNTech jab showed it was 95 per cent effective at stopping people becoming ill with Covid-19 if they are infected. But the new data suggests that the vaccine could also stop people becoming infected at all.  

Initial studies of data from Israel’s world-beating vaccine drive suggest that the first dose of the  can curb infections by up to 50 per cent after 14 days – raising hopes that vaccination efforts will have an even more dramatic effect.    

With Israel rolling out the world’s fastest vaccination programme, handing out 1.9million doses in less than four weeks, studies of hundreds of thousands of people offer perhaps the most extensive real-world data on the vaccine’s efficacy. 

Sharon Alroy-Preis, head of the Health Ministry’s public health department, announced the 50 per cent figure to Channel 12 news, though cautioned that results are preliminary and need to be treated with caution.

Separately, two pieces of research by healthcare providers Maccabi and Calit showed infections dropped by 60 per cent and 33 per cent, respectively, after a first dose of vaccine.

The preliminary studies, which examined hundreds of thousands of patients, were both reported in Israeli media, though the data behind them has not been released to the public meaning no explanation has been given about the discrepancy in their figures.

Health minister Yuli Edelstein has warned Israelis to remain cautious even after a first dose of vaccine, amid concerns they could still catch the disease. 

On Tuesday, Israel saw daily Covid-19 infections and active cases reach all time-highs. On Tuesday, Israel reported 9,997 new cases - its highest in a single 24 hours - and 46 deaths, after recording a record 67 deaths on Monday

Israel is well ahead of other countries in its vaccine drive, administering 23.66 doses per 100 people, as of January 14. The second highest rate has been achieved by the UAE, with 14.1 per 100 people. In comparison, the UK has administered 4.52 per 100 people

Dr. Sharon Alroy-Preis, head of the Health Ministry’s public health department, stressed to Israel’s Channel 12 that the research was preliminary, and highlighted the need for caution – even among those that have received the first dose of jab. 

Alroy-Preis noted that the data was not enough to conclude that the vaccine stops transmission of Covid-19, because it is believed that a person can still spread the virus to others for a limited time if it is still located in their nasal cavity. 

She added that nearly one-fifth of the more than 1,000 serious Covid-19 patients in the country had previously received the first does of the vaccine.

‘Seventeen percent of the new serious cases today, or 180 cases, are after the first dose,’ she told reporters.   

On Tuesday, Israel saw daily Covid-19 infections and active cases reach all time-highs, and despite the optimistic signs, the country’s health minister also stressed there was still the need for extreme caution. 

The vaccine is only expected to give a person 95 percent immunity against Covid-19 a week after receiving the second dose of the vaccine. Rollout of the second dose in Israel is set to begin this week, according to The Times of Israel

Speaking to The Telegraph, Yuli Edelstein, the country’s health minister, warned that there was still a risk of catching the virus within two weeks of being given the jab, saying that Israelis must stay vigilant.

‘Those who are getting the first shot should still be very, very cautious about their behaviour, due to the partial resistance to the disease,’ Mr Edelstein said.

‘In my imagination, it’s like the scene from the movie where you nearly escape the danger, and at the very last moment you catch a bullet.’ 

He added: ‘It shows what we have already known, which is that the full 95 per cent protection comes after two shots.’ 

The two studies carried out by health maintenance organisations (HMOs) compiled the data from some 400,000 patients they treated (800,000 in total), with the reason behind the discrepancy (60 percent and 33 percent) currently unclear.

The Clalit study compared test results of a group of 200,000 people who had been given the vaccine to a sample of 200,000 Israelis who had not received the jab.

The full results of the study are yet to be released or peer reviewed. 

Israel’s vaccination programme is so far the fastest in the world and has given the vaccine to more than two million people – around 20 percent of its population.

The programme runs 24/7, even on the Jewish holdy day of Shabbat, and is being boosted by hundreds of Israeli combat medics who have been culled in for duty.

Given that Pfizer’s phase 3 trials only checked 40,000 people, the data from Israel’s vaccination campaign could offer some of the best indicators for the vaccines effectiveness against the coronavirus.

The Times of Israel reports that the latest number given by officials was 1,910,330 – although Prime Minister Benjamin Netanyahu held a ceremonial event celebrating the 2 millionth vaccine on Tuesday.

Israel has reported a total of 520,060 confirmed cases of coronavirus since the start of the pandemic, with 3,817 related deaths.

On Tuesday, Israel reported 9,997 new cases – its highest in a single 24 hours – and 46 deaths, after recording a record 67 deaths on Monday.

Like many countries, Israel is facing a second wave of the virus in winter after the rate of new infections and related deaths dropped during November.

On January 5, the government announced a two-week national complete lockdown, effective from January 7. The lockdown is set to expire at the end of the month, but is almost sure to be extended as new cases and deaths continue to rise.
