Pfizer announces that its COVID-19 vaccine is 90% effective, based on tests with 44,000 people. The vaccine may be available by the end of the year. Is this the end of covid-19? Thereby, Pfizer herself stresses that the results are based on the third stage of testing. And that testing stage hasn’t been completed yet. We have analyzed the reactions of experts on this news.

The good news: hope on a working vaccine

Obviously, a vaccine that works against corona is good news anyhow. How good, is another question. While most experts say that they can judge the vaccine really if tests are completed and the underlying data is available, most experts are possitive about the news

How good is the vaccine?

Analyzing the reactions of experts, some of important questions to judge the effectiveness of the new vaccine are:

  • what is the duration of protection?
  • is the vaccine protecting the elderly, since the immune system weakens with age?
  • Does the vaccine protect from spreading the virus?
  • ‘scientific questions’ and logistics

What is the duration of protection?

In this stage, it is unclear what the duration of the protection is. Of course, the vaccine is still in its testing stage. Besides, our knowledge of covid-19 has much improved since the outbreak. But due to the youth of this virus, we still know little about it. In the ideal world, we would have a vaccine which would protect a lifetime. If it doesn’t, how long will the protection last?

Is the vaccine protecting the elderly?

It remains unclear if the vaccine is protecting the elderly as well as youthful people. The elderly and weak persons would benefit the most of a working vaccine. They have the largest risk of getting seriously ill. Leading to hospital or even death. But: as age increases, the immune system weakens. The BBC explains this in this article…

Does the vaccine protect from spreading the virus?

The third point which is unclear, is if the vaccine only protects the injected person from getting ill. Or that it protects the vaccinated from spreading the virus as well.

‘Scientific’ questions and logistics

The fourth question are some ‘scientific’ questions and logistics. Many experts state that they need to see the data first before they can make a real judgement (and again: also, Pfizer emphasizes that their message is based on testing results). Besides there’s the point of logistics: when there will be final proof of the effectiveness, Pfizer won’t be able to produce the vaccine for the whole world immediately. So, countries who have bought already the vaccine will go first. Probably, the weak and caretakers will be vaccinated first.

Science Media Centre has collected “reactions to pfizer and biontech reporting interim results from phase 3 covid-19 vaccine trial in this article. We quote from this article the reaction of Prof Jonathan Ball, Professor of Molecular Virology, University of Nottingham: “It’s great news that the Pfizer vaccine is reported to be 90% effective, but it’s important to understand what that means.  For a vaccine to be truly effective it needs to protect those most vulnerable from suffering severe COVID-19 or prevent those less vulnerable from becoming infected and then transmitting the virus to others.  Simply reducing the appearance of symptoms in people who would otherwise have experienced mild infection, is unlikely to have a major benefit.  Indeed, in a worst-case scenario if vaccinated people become infected with the virus and assume they are protected it might mean they can still spread the virus asymptomatically.  Vaccines will be incredibly important in our battle against this virus, but we need to be assured that they will perform as we would hope.”

Following the Covid-19 measures remain important

We believe that, at least before there is a working vaccine largely available, following the Covid-19 measures remain important, such as: wash your hands regularly, wear a mouth mask and keep the social distance. Find out how a Covid buzzer can help you with keeping the social distance here.

Used sources

While in the Netherlands and some other countries Covid-19 is increasing because people don’t follow regulations like social distancing and wearing a mask properly, Covid-19 has set a worldwide ‘record’ today.

WHO reports 284,196 new Covid-19 infections in the last 24 hours (July 24). This is a record for the highest increase of corona infections in 1 day. The largest increases were in the US, Brazil, India and South Africa. The previous ‘record’ was one week ago, at July 18.

There were 9,753 deaths, the highest number since April 30. The average number of deaths per day is also increasing: in July 5,000 persons; in June 4,600.

Social distancing, wearing a mask properly and solutions like a covid buzzer help to fight Covid. Find out how we can help you: the Covid Buzzer

A few days ago, the New York Times headlined ” 239 Experts With One Big Claim: The Coronavirus Is Airborne”. At least in the Netherlands, some people are focusing on these aerosols as more are less the only source of infection. According to them, Social distancing would have no use. Should we stop with washing hands, route marking and solutions like the covid buzzer? What does Morawska really say in her article?

Now, Morawska c.s. have publiced their article. In this, she focusses on aerosols as a third way of possible/probable Covid 19 infections, besides direct contact and large droplets:

“Inhaling small airborne droplets is probable as a third route of infection, in addition to more widely recognized transmission via larger respiratory droplets and direct contact with infected people or contaminated surfaces.”

“Inhaling small airborne droplets is probable as a third route of infection, in addition to more widely recognized transmission via larger respiratory droplets and direct contact with infected people or contaminated surfaces. … We believe that the use of engineering controls in public buildings, including hospitals, shops, offices, schools, kindergartens, libraries, restaurants, cruise ships, elevators, conference rooms or public transport, in parallel with effective application of other controls (including isolation and quarantine, social distancing and hand hygiene), would be an additional important measure globally to reduce the likelihood of transmission and thereby protect healthcare workers, patients and the general public.”

In other words: they mention aerosols as a possible / likely distributor of Covid 19, so not as the only explanation. They also mention the widely accepted distributions due to the large droplets and direct contact.

Social distancing remains important, solutions such as washing hands, good marking and covid buzzer help.

The Dutch Newspaper De Gelderlander (June 16) headlines: “Where is the virus, am I safe, am I at risk?” The newspapers write this article in response to the major demonstrations in Amsterdam and Rotterdam two weeks ago. The social distancing measures were not adhered to, as if Covid-19 did not exist. They continue: “Half the country shuddered at the sight of a full Dam. Two weeks later, the coast seems clear. Where are we at risk? Time for a mid-term review. “

The newspaper concludes that there are relatively more infections in South Holland.

Then: “Can we have big events again?” The 2 large demonstrations did not cause a major virus outbreak. That is why many hope that large events can be organized again. “Don’t do it, experts warn … The virus is not yet gone, so such events are big risk moments. The more often you organize those, the more likely it will lead to infections”

Risk situations: frequent mutual contact

Based on various outbreaks, there appears to be 1 major risk situation: places where there is a lot of mutual contact. In addition, the newspaper mentions the outbreak in 2 mosques. Besides, they mention the outbreaks in meat processing and fruit growing. “It is clear that sectors with many migrant workers, who often live close together, are hit harder.” In addition to employees, people who regularly visit these companies were professionals who tested positive, such as drivers.

Finally, the newspaper concludes with the WHO’s warning that places where fruit and meat is traded have risks of major outbreaks. After no new Covid cases were found in China for 2 months, there is currently another outbreak in Beijing.

1.5 meters: Social Distancing remains important

Many companies such as offices and factories are currently investigating how they can safely reopen their company for their staff and visitors. Events, cultural institutions and the catering industry also want to offer the safest possible environment. It remains important to keep 1.5 meters away.

As of 1 June, many museums in the Netherlands have reopened to a limited extent: a maximum of 30 people can enter at the same time and they must be kept at least 1.5 meters apart. From July 1, this capacity will be increased to 100 people, if there are no problems. Under which conditions this will happen is not known. In any case, museums and events will have to ensure that the 1.5 meters is maintained.

Many museums are taking measures to provide visitors and employees with a safe environment. Find out how the Covid Buzzer can help.

Maximum capacity and time slots

The most obvious measure is to limit visitor numbers at the gate: visitors sign up for a time slot. A museum usually calculates the capacity per time slot on the basis of the available space. In any case, until 1 July, 10m2 must be available per visitor. The average duration of a museum visit is then also important: on the basis of its capacity and the average duration, the museum has an indication of the number of time slots required and the mutual overlap of these time slots.

Irregular spread

However, visitors will not be regularly scattered around the building. It is likely to be busy at some parts of the building: at entrances, wardrobes, toilets, museum shops, etc. And the same applies to the absolute top pieces: the pieces that all visitors want to see and want to view for quite some time. Museums have created walking routes and have made capacity planning that takes into account crowds at the ‘hot spots’ and where an extra security guard must be placed.

Self-regulating power and more capacity with the Covid Buzzer

Offering “experience” is an important condition for a successful museum visit. Visitors also want to feel welcome in Covid time. Many visitors will understand that for safety reasons they may be led through 1.5 rows along the top piece with a distance of 1.5 meters. For the rest, they will prefer to design their visit as much as possible themselves.

When visitors are enjoying themselves, they may forget to keep a distance. In addition, there will unfortunately always be visitors who do not want to take other visitors into account at all.

The Covid Buzzer helps visitors keep 1.5 meters social distance. By having every visitor wear a Covid Buzzer, these problems are solved. This goes off when visitors come within a radius of 1.5 meters. The Covid Buzzer can also offer a solution for the masterpieces, by letting visitors ensure that they keep a distance of 1.5 meters. And employees can address those who do not obey the rules several times.

Covid Buzzer: Simple, reliable and no privacy issues

 The simple solution to keep a safe distance between each other. Everyone in the office, factory or elsewhere where many people gather, wears a buzzer. As soon as the buzzer meets another buzzer within a radius of 1.5 meters, a warning signal follows. The buzzer is completely anonymous, so there are no privacy issues involved. Thanks to UWB technology, the Covid buzzer has 10 cm accuracy.

Government rules after July 1; proof for 1.5 meters

As mentioned, the regulations are still unclear after 1 July. Much will depend on the extent to which museums and other visitors attracting institutions appear to be able to comply with the 1.5-meter provisions.

With the Covid Buzzer, museums show that they are actually able to adhere to the 1.5-meter stipulation.
