A large French study involving 22 million people has shown that COVID vaccines dramatically reduce a person’s risk of being severely impacted by the disease. While being vaccinated doesn’t guarantee you won’t catch COVID or indeed become ill, it does, however, reduce your risk of being hospitalised or dying by as much as 90 per cent. The study, published Monday, also found two-dose vaccines, such as Pfizer-BioNTech, Moderna and Oxford-AstraZeneca, protect against the worst effects of the so-called Delta variant. For people aged 75 and older, such vaccines offered 84 per cent protection. This figure rose to 92 per cent for people 50 to 75. The results were the same for each vaccine manufacturer. “The vaccine was never really intended to stop the disease,” says Dr. Ulysses Wu, Hartford HealthCare’s System Director of Infection Disease and Chief Epidemiologist. “It was a very nice side effect that we were preventing disease, but it’s main purpose is to prevent the morbidity and mortality should we get the disease. It was really to take a deadly disease and turn it into the common cold.” The study was conducted by a scientific group set up by France’s health system (Epi-Share), its national insurance fund (l’Assurance Maladie) and its medicine agency (ANSM). N.B. The Johnson & Johnson vaccine (Janssen) was not included in the research due to an insufficient number of patients for comparison. * Image by Surprising_Shots from Pixabay
French Health Minister Olivier Véran has hailed the country’s Covid-19 health pass as a success, adding that similar initiatives are now being introduced in “dozens” of other countries around the world. Speaking to France 5, Mr Véran said other countries were now considering similar initiatives having seen the impact made in France. The health pass obliges people to show proof of full vaccination, a recent negative test or recent recovery from Covid-19 to be able to enter restaurants, bars and a range of other public spaces. Since the pass was announced by President Emmanuel Macron on July 12, some 12 million people (equivalent to 18% of France’s population) have been vaccinated, according to Prime Minister Jean Castex. Back in March, only 3% of the French population had been fully vaccinated against Covid-19, according to Le Monde. But this figure has now risen to 67%, highlighting how more and more people are receiving a Covid vaccine. Interestingly, take-up among the young has been particularly high considering vaccination was delayed for this group. Meanwhile, Covid health passes will no longer be required for entry into all but 64 French shopping centres this week. From Wednesday the health pass obligation will no longer apply to centres of more than 20,000 square metres in departments where the infection rate has dropped below 200 per 100,000 residents, and where cases have been falling for a week or more, Economy Minister Bruno Le Maire announced yesterday (September 6). *Image by Please Don't sell My Artwork AS IS from Pixabay
France extended its mandate to carry Covid-19 health passes to certain categories of workers as of yesterday. The move marks a new stage in the French government’s strategy to encourage members of the public to have Covid-19 vaccines. Under the new rules, staff who work face to face with the public – for example, at cafés, cinemas or on public transport – are now required to show proof that they are fully vaccinated or have tested negative for the coronavirus in the last 72 hours. Some 1.8 million workers across the country will be encompassed by the measures. Members of the public are already required to carry health passes in order to access eateries and cultural or leisure venues. While polls suggest a majority of the public supports Covid-19 health passes, their introduction has led to protests throughout the summer, with tens of thousands of protesters staging rallies across the country on consecutive weekends. The government insists the pass is necessary to encourage vaccination uptake and avoid a fourth national lockdown, with the unvaccinated accounting for most of the Covid-19 patients admitted to hospital.

New Covid-19 treatments should be widely available in France before the end of the year, the head of the country's Scientific Council has predicted. According to a report in Le Parisien newspaper, Jean-François Delfraissy, an immunologist and president of the Conseil scientifique, which advises the government on medical matters, said monoclonal and polyclonal antibody treatments would be made more widely available in the coming months. Monoclonal antibody treatments are made using Covid-19 survivors’ own antibodies and are designed to fight infection just as the natural immune system would. Former US President Donald Trump received monoclonal antibody drugs when he was hospitalised with Covid-19 in 2020. At the beginning of August, French health authorities authorised the use of monoclonal antibody treatments for immuno-compromised patients who cannot be vaccinated against the virus because of their conditions. The treatments are set to be rolled out for use as required by doctors among the wider population before the end of the year. A number of pharmaceutical companies are in the process of applying for medical authorisation. They would be “effective for high-risk patients, and should reduce the number of hospitalisations”, Le Parisien reported, but would only be available under medical supervision. The drugs are intended for use in patients who are already severely ill with Covid. They do not prevent people developing the illness in the first place. *Image by Klaus Hausmann from Pixabay
On Tuesday, France lowered the age of eligibility for COVID-19 vaccines to 12, opening the door for millions of French children to receive a boost to their resilience to the coronavirus pandemic. Perceval Gete, a 12-year-old French boy from the suburb of Vitry-sur-Seine, was one of the youngest people in Europe to receive a COVID-19 vaccination, according to reports. To accommodate his young age, the nurse administering the jab had to use a special child-size needle. “I wanted it to be done as soon as possible,” his mother, Melanie Gete, said at the vaccination center in the suburb of Vitry-sur-Seine after Perceval had the jab. Prior to the rule change, people in France had to be at least 18 years old, or 16 if they had underlying conditions, to be eligible to receive a COVID-19 vaccination. Now, providing they have parental consent, children as young as 12 can be vaccinated. In wealthy countries worldwide, governments have been expanding their vaccination programs to include younger people, who, it is worth noting, are less likely than older individuals to get seriously ill from COVID-19. However, France’s limit of 12 years is one of the lowest of any major European Union state. Nurse Aurelie Job, who administered the vaccine to Perceval Gete on Tuesday, used a needle that is around half the length of the standard size used for adults. “Children have smaller arms so we need smaller needles to vaccinate children,” she said. “It prevents us from touching the bone while vaccinating children, and it’s less upsetting for them.”
Germany, France, Italy and Spain have joined the list of countries to suspend use of AstraZeneca’s COVID-19 vaccine. The countries took the decision after reports have arisen of dangerous blood clots in some recipients. Meanwhile, AstraZeneca and European regulators have said there is no evidence the vaccine is to blame. The AstraZeneca shot is one of three vaccines currently in use in Europe. Nevertheless, the blood clot concerns and subsequent cessation of its use represents another setback for the EU’s vaccination drive – which has already been slow off the mark compared to similar campaigns in the United Kingdom and the United States. The EU’s drug regulatory agency has called a meeting for this week to review experts’ findings on the AstraZeneca vaccine and decide how to proceed. All this comes as much of Europe tightens restrictions on schools and businesses as Covid-19 cases surge. In Germany, the decision to halt the use of the Astrazeneca vaccine was taken following advice from the country’s vaccine regulator, the Paul Ehrlich Institute. It called for further investigation after blood clots were found in the brains of seven people who had been vaccinated. In response to the situation, Astrazeneca published a press release offering ‘reassurance on the safety of its COVID-19 vaccine based on clear scientific evidence’.
France is gearing up for a possible easing of COVID-19 lockdown restrictions from mid-April, as vaccines, to date, are proving effective at lowering infection rates. French government spokesman Gabriel Attal said on Wednesday that while the nation is still facing hard times, “For the first time in months, the return to more normal living conditions is in sight.” Attal said vaccinated groups (mainly the elderly) are witnessing falling infection rates, which, he said, is a sign that the country’s vaccination program is working and should be sped up. "It is neither a distant nor uncertain horizon - it is an horizon that is getting closer and closer. We hope maybe from mid-April, and we are preparing for it. "The president (Emmanuel Macron) asked us to submit proposals that could allow for a cautious re-opening of the country soon,” he said. Attal added that the goal of vaccinating the most fragile was to reduce hospitalizations and safeguard the nation’s health care system, which is key to easing restrictions. Earlier this week, Health Minister Olivier Veran said France will retain its current measures aimed at limiting the spread of COVID-19, including a nighttime curfew, as a bare minimum for the next four to six weeks. Other measures now in force include the closure of bars, restaurants, museums, sports and music venues. COVID-19 is the disease caused by the coronavirus.
People in France aged over 65 with existing health problems will be allowed to be given the AstraZeneca COVID-19 vaccine, after the French Government reversed its policy. When the AstraZeneca vaccine was approved for use by European Union regulators, the French Government said it should only be given to eligible people under 65 because data from trials in older age groups was limited. The AstraZeneca vaccine will now be offered to people up to the age of 74. However, the shot has been hit by a slow rollout and a lack of trust. French Health Minister Olivier Veran said Monday: "Anybody aged 50 or over who is affected by co-morbidities can get the AstraZeneca vaccine, including those between 65 and 74." The announcement has the potential to affect more than two million people. British health authorities released new data on Monday that showed the AstraZeneca vaccine reduced hospitalization from COVID-19 by more than 80%. The vaccine is widely used in the UK but has missed delivery targets in the EU. People aged 75 and over would continue to get the Pfizer and Moderna vaccines only, Veran said. Meanwhile, Germany still hasn’t cleared the AstraZeneca vaccine for over 65s. This has led to fewer people stepping up for the shot and several doses being wasted.

A single dose of Pfizer/BioNTech’s Covid-19 vaccine reduces a person’s risk of infection by 72%, a new study has revealed. According to Public Health England (PHE), the first dose of the Pfizer/BioNTech Covid-19 vaccine "provides high levels of protection against infection and symptomatic disease.” PHE's Siren Study, which involved healthcare workers aged under 65, found that one dose of the Pfizer/BioNTech Covid-19 vaccine reduced the risk of infection by 72% after three weeks. Two doses of the vaccine reduced the risk of infection by 85%. This high level of protection also includes the B.1.1.7 coronavirus variant first identified in the UK in December. For the study, health workers were tested for Covid-19 infection every two weeks using PCR tests and twice a week with lateral flow tests. As Dr. Susan Hopkins, strategic response director at PHE, explained, "there was a lot of asymptomatic testing.” "Overall we are seeing a really strong effect to reducing any infection: asymptomatic and symptomatic," Hopkins said during a press conference held by the UK's Science Media Centre on Monday. Promising early data has also shown that people who are vaccinated and subsequently catch Covid-19 are far less likely to die of, or be hospitalized with, the virus. For example, people over the age of 80 who were infected after being vaccinated were 41% less likely to be hospitalized with the virus and 57% less likely to die of it.
The World Health Organization (WHO) yesterday gave two versions of the AstraZeneca/Oxford COVID-19 vaccine the green light to be used for emergency use, listing them on its Emergency Use Listing (EUL), paving the way for them to be rolled out globally through COVAX. The vaccines are produced by AstraZeneca-SKBio (Republic of Korea) and the Serum Institute of India. WHO’s EUL assesses the quality, safety and efficacy of COVID-19 vaccines and is a prerequisite for COVAX Facility vaccine supply. It also allows countries to expedite their own regulatory approval to import and administer COVID-19 vaccines. “Countries with no access to vaccines to date will finally be able to start vaccinating their health workers and populations at risk, contributing to the COVAX Facility’s goal of equitable vaccine distribution,” said Dr Mariângela Simão, WHO Assistant-Director General for Access to Medicines and Health Products. ‘But we must keep up the pressure to meet the needs of priority populations everywhere and facilitate global access. To do that, we need two things – a scale-up of manufacturing capacity, and developers’ early submission of their vaccines for WHO review.” Pfizer/BioNTech’s vaccine was listed for emergency use by WHO on 31 December 2020.
Last Saturday, February 6, France reported both a fall in new COVID-19 infections and in the number of patients being treated in hospital. The country registered 20,586 new confirmed COVID-19 cases, down from 22,139 the previous day and marking the third straight daily fall. Meanwhile, hospitals across the country were treating 27,369 people for the disease, down 245 from the previous day, marking the fourth consecutive daily fall. The fall in numbers comes as France continues with its COVID-19 vaccination programme, with 1.86 million people now having received their first dose. Almost a quarter of a million people (247,260) have also received their second dose. At present, France has three vaccines approved for use: Pfizer/BioNTech, Moderna and AstraZeneca, the latest to be received. The country has taken delivery of 273,600 AstraZeneca, according to the health ministry, with a second batch of 304,800 doses scheduled to be delivered this week. The initial AstraZeneca shots were prioritized for health personnel under 65, with the first injections taking place over the weekend. While the arrival of the AstraZeneca shot will help France accelerate its vaccination programme, the quantities that are expected to be delivered are likely to be less than first thought. Nevertheless, with a third approved vaccine and COVID numbers falling, pressure on the French health system is easing day by day.
With reports emerging that several different COVID variants are now circulating around the world, Moderna has released a statement saying it believes its vaccine protects against at least two of the new strains. Moderna Inc said on Monday it believes its COVID-19 vaccine protects against both new variants found in Britain and South Africa. However, the American pharmaceutical and biotechnology company also said it will test a separate booster shot aimed at the South African variant after concluding the antibody response could be diminished. The company said in a press release that it found no reduction in the antibody response against the variant found in Britain. Against the South African variant, Moderna said it found a reduced response but still believed its two-dose regimen would provide protection. The emergence of new COVID variants in Britain, South Africa and Brazil has created some concern that mutations in the virus may make vaccines less effective. Moderna’s announcement will serve to alleviate some of that concern, but the proof will be in the infection numbers going forward. Moderna shares rose nearly 10% off the back of the news during Monday trading. Moderna said it plans to publish data from its tests against the variants on the website bioRxiv.
With Covid-19 vaccines now being rolled out in many countries across the world, a number of tech giants are teaming up to help facilitate the return to "normal". A coalition known as the Vaccine Credential Initiative — which boasts healthcare and tech leaders, including Microsoft, Salesforce, Oracle, Cerner, Cigna's Evernorth, and the Mayo Clinic (among others) in its ranks — wants to ensure that everyone has access to a secure, digital record of their Covid-19 vaccination. This kind of digital vaccine passport, which can be stored in people's smartphones, could be used for everything from airline travel to entering concert venues. The coalition has even considered those without smartphones. Such individuals will be given a printable QR code containing their record that can be scanned wherever they go. "Just as Covid-19 does not discriminate based on socio-economic status, we must ensure that convenient access to immunization records crosses the digital divide," Brian Anderson, chief digital health physician at non-profit research organization MITRE, a member of the coalition, said in a statement. With such vaccine passports in place, a healthy and safe return to work, school, travel and life in general can be accelerated.
The United States (US) and the United Kingdom (UK) have started national Covid-19 vaccine rollouts, as the pandemic situation in each country continues to worsen. In the United States, the first batches of Pfizer/BioNTech’s Covid-19 vaccine left a Michigan manufacturing plant on Sunday bound for 150 locations across the country. The vaccine will now be given to the most vulnerable Americans, including frontline health workers and long-term care home residents. The United States is slowly approaching the once unthinkable threshold of 300,000 Covid-related deaths. Meanwhile, the UK witnessed its first Covid vaccination last week. It was given to 90-year-old Margaret Keenan, with up to four million more expected to follow by the end of December. The UK made history earlier this month when it became the first country in the world to approve the Pfizer/BioNTech Covid-19 vaccine for use. The Covid-19 vaccine rollout in the UK comes as the capital, London, witnesses a surge in cases. As a result, London and several other areas in the south-east will this week enter the toughest coronavirus restrictions (tier 3) in an attempt to curb the spread of the virus and reduce infection numbers. The UK has ordered 40 million doses of the Pfizer/BioNTech vaccine — enough to vaccinate 20 million people — with the first 800,000 doses coming from Pfizer's facilities in Belgium to the UK this week.
Moderna Inc. says its experimental vaccine is 94.5% effective in protecting people from Covid-19. The claims are based on interim data from a late-stage clinical trial. Moderna is the second US company to announce a Covid-19 vaccine this week, following in the footsteps of Pfizer, whose own vaccine boasts a 90% efficacy rate. The Moderna announcement means that there could be at least two vaccines authorized for emergency use in the United States in December.As many as 60 million doses could be available by the end of 2020. Moderna and Pfizer’s vaccines are both built using new technology known as messenger RNA or mRNA. Both represent powerful new ways to combat the ongoing pandemic, which has to date infected 54 million people and killed 1.3 million. Both vaccines also come at a time when Covid-19 cases appear to be surging – especially in the US where new cases of the virus are now totaling more than one hundred thousand per day. Unlike Pfizer’s vaccine, Moderna’s does not need to be stored at ultra-cold temperatures, making it easier to distribute. This is particularly good news for countries like India with hot climates that would struggle to keep Pfizer’s vaccine at the required -70°C. Speaking about the firm's vaccine, Moderna President Stephen Hoge said: “Assuming we get an emergency use authorization, we'll be ready to ship through Warp Speed almost in hours. So it could start being distributed instantly.”
As the number of SARS-CoV-2 infections around the world passes eight million, hopes still remain on a vaccine being developed. But what does it mean for a potential vaccine if the new coronavirus mutates? Well, the bottom line is that all viruses mutate, it is part of their life cycle, so there’s a very good chance that SARS-CoV-2 will too. The good news though is that mutations can actually lead to weaker viruses, although the reality is that there’s usually no noticeable difference in the disease’s transmission and fatality rates. This seems to be the case with SARS-CoV-2. Mutations that are currently spreading around places like New York do not seem to be any more infectious or fatal than the original strain that came out of Wuhan, China, in late December. According to the Scripps Research Institute in Florida, any SARS-CoV-2 vaccine that is developed will also likely be effective against mutated forms of the virus. It’s the reason why our very effective vaccine for measles, mumps, and rubella (which are RNA viruses like SARS-CoV-2) still protects us, despite these viruses mutating over the years. So even if SARS-CoV-2 mutates further down the road, while we might see some breakthrough infections, it wouldn’t necessarily lead to a new pandemic.
