Here are the most promising coronavirus vaccine candidates out there

  Here are the most promising coronavirus vaccine candidates out there Scientists around the world are creating dozens of unique vaccine candidates to fight the novel coronavirus — and they're doing it at unprecedented speeds. require(["medianetNativeAdOnArticle"], function (medianetNativeAdOnArticle) { medianetNativeAdOnArticle.getMedianetNativeAds(true); }); Over seven months after the World Health Organization (WHO) first alerted the world to a mysterious cluster of pneumonia cases in Wuhan, China, 167 candidate vaccines are in development to prevent the coronavirus that caused the disease (called COVID-19), according to WHO.

Governments must start preparing in advance for transporting billions of Covid-19 vaccine doses around the world, a massive and complex logistics task, or risk severe capacity constraints, the International Air Transport Association (Iata) warned. Providing just a single dose of the vaccine to

Frankfurt Airport is Europe's largest pharmaceutical transshipment point. Lufthansa is also hoping for a lucrative business with the distribution of corona vaccines. Ultra-low temperature containers must be used.

The preparations for supplying the world with long-awaited vaccines against Corona have been in full swing in aviation for months. Frankfurt Airport, the largest transshipment point for air freight of sensitive pharmaceutical products that need to be refrigerated, plays a central role in this. A total of 13,500 square meters of precisely temperature-controlled space is available, 8800 of which Lufthansa uses.

Why it’s still unlikely we’ll have a Covid-19 vaccine before Election Day

  Why it’s still unlikely we’ll have a Covid-19 vaccine before Election Day Trump wants a vaccine before November, but his top advisors say that’s near impossible.“The week before last, the head of the Centers for Disease Control Dr. Redfield said it would be summer before the vaccine would become generally available to the public. You said that he was confused and mistaken,” Wallace said.

Vaccines save millions of lives each year. Vaccines work by training and preparing the body’s natural defences --- the immune system--- to recognize and fight off the viruses and bacteria they target. If the body is exposed to those disease-causing germs later, the body is immediately ready to destroy them

airline boss Carsten Spohr relies on a "large, highly profitable business" for the freight subsidiary Lufthansa Cargo. "As sad as it is, this crisis and the need for vaccination, this is going to be bigger business," he said recently. Lufthansa and its subsidiary Swiss Worldcargo were among the few airlines in the world that offered seamless refrigerated transport. Your competitors are, for example, the cargo airline Cargolux or the golf airline Emirates.

Securing supply chains

At Frankfurt Airport, the threads of all those involved in air freight - freight forwarders, freight handlers, airlines and the airport operator Fraport - come together at the Air Cargo Community Frankfurt. Your pharma working group has been dealing with various scenarios since March to prepare the supply chain, said Joachim von Winning, chief executive of the Air Cargo Community, the Reuters news agency.

How many coronavirus vaccine doses each US state will get to start

  How many coronavirus vaccine doses each US state will get to start The federal government is allocating COVID-19 vaccine doses to states according to their populations.Most states have announced how many doses they expect to receive in the first batch once a vaccine is approved.

Coronavirus, Covid-19, Corona Vaccine Covaxin India Update: In general, a vaccine is developed and tested over a number of stages. For Covid-19, this has been fast-tracked in various ways.

Is there a vaccination ? No vaccine is available at this time. However, you can still get vaccinated for the seasonal flu, which physicians recommend. What do I have to consider at the aviation security checkpoint? Keep a distance of two arm lengths from other persons. Prepare for control!

Within Europe, most vaccine contingents are not delivered by plane, but by truck, as production takes place on the continent. "For our planning we assume that we mainly have to process exports from Europe, for example to Africa. Or that vaccines from India and China are handled in Frankfurt." The concept for the processes envisages that up to five aircraft can be loaded and unloaded at the same time. "Temperature damage is avoided by short transport routes."

It becomes a particular challenge when vaccines such as those of the Mainz biotech company Biontech and the US pharmaceutical giant Pfizer are used, which are currently used only need to be transported ultra-frozen at temperatures as low as minus 80 degrees Celsius.

FDA advisory committee to consider second COVID-19 vaccine, this one from Moderna, during all-day meeting

  FDA advisory committee to consider second COVID-19 vaccine, this one from Moderna, during all-day meeting An FDA advisory panel is expected Thursday to recommend authorization of the COVID-19 vaccine developed by Moderna. It could be in states by Monday.This time, the committee is reviewing a vaccine made by Cambridge, Massachusetts, biotech Moderna, with similar technology and results as the one it supported last week by Pfizer and its German collaborator, BioNTech.

Human trials will begin imminently – but even if they go well and a cure is found, there are many barriers before global immunisation is feasible.

Vaccine development usually takes years and unfolds step by step. Experimental vaccine candidates are created in the laboratory and tested in animals before moving These steps are now overlapping in the race to find a vaccine for a global disease that has killed hundreds of thousands of people.

"For air freight, there are special, so-called active, electronically controllable and controllable containers that are very expensive - they cost about as much as a small car", explained von Winning. The manufacturers - such as Envirotainer from Sweden, Dokasch from Germany or C-Safe from the USA - rented the transport containers to airlines and forwarding agents. It is possible that large numbers of them would only be needed for a few months if the vaccine, which needs to be kept cold, was further developed to tolerate higher levels.

Dry ice for extreme cooling

In order to achieve extreme cold, dry ice is used - but this limits the amount of freight allowed for safety reasons. Because dry ice releases CO2, which takes the air away from the people on board to breathe. According to DHL, long-haul aircraft such as the Boeing 777 are allowed to take a maximum of 1088 kilograms of dry ice. "Depending on the type of aircraft, there are usually not more than a few containers on board at the same time," said von Winning.

Coronavirus outbreak: Live Updates

  Coronavirus outbreak: Live Updates Among the top news today: COVID-19 cases continue to surge across the U.S., FDA expected to authorize Moderna's vaccine today.A 90-year-old woman (who will turn 91 next week) became the first in the world to be given Pfizer's coronavirus vaccine outside of clinical trials, according to the BBC. Margaret Keenan, who is originally from Northern Ireland, was given the vaccine at the University Hospital in Coventry, England. She received the first of 800,000 doses expected to be administered in the U.K. in the coming weeks, according to the BBC. "I feel so privileged to be the first person vaccinated against Covid-19," Keenan said, according to the BBC.

estimates of how many flights have to take off for a global supply of Covid vaccines range from 8,000 by the international aviation association IATA to around 15,000 by DHL. In order to get a piece of this cake, a task force at Lufthansa Cargo has been working on the organization since June, considering all possible scenarios. "Today we can say that all logistical processes are in place, they are largely standardized," said company spokesman Andreas Pauker.

The containers roll between the truck and the cold store through a "cooled finger" that protects against temperature fluctuations. Ultra-deep freeze transports are also feasible, but the exact requirements for packaging, transport and storage are not yet clear.

Freight capacity decreased due to Corona

Cargo capacity fell by a third due to the large number of passenger planes on the ground during the Corona crisis at Lufthansa Cargo. "That is a critical point," said Pauker. "Hopefully the passenger air traffic will start again." Because then there would be more cargo capacity again due to loading on the lower deck.
