The race to find effective vaccines that oppose the Covid-19 is ahead of the race to gain some access.And with headlines like “The Covid-19 vaccine can arrive at the end of October; The White House says there’s no tension in the calendar.”, “the prospect of a vaccine” soon “is strangely close.
But “soon” means other things, depending on where you are in the world.
With the advance purchase of about two billion doses of Covid-19 vaccines that are still under development in the US, the US has been able to make the most of its allies.United States, the United Kingdom and the European Union, the impending consultation, especially for countries such as South Africa.South and nearly a hundred emerging countries with even less economic strength and limited vaccine production capacity: the question is whether, despite many high-level discussions on global solidarity, we will have vaccines in our hands as soon as they are effective.. Globally limited vaccine production capacities, mainly located in rich countries, mean that some form of “rationing” will be required, even with increases in production capacity underway around the world.
On 4 September 2020, the Director-General of the World Health Organization, Dr. Tedros Adhanom Ghebreyesus, said, “We need everyone else in the world to have access to vaccines,” recognizing that materials will be limited in the first place.”The first priority deserves to be to vaccinate some other people in all countries, than everyone else in some countries,” he said.
Not all WHO Member States feel the same way.So how does the ideal of global solidarity oppose countries’ brazen “vaccine nationalism”?
COVAX, which is the “arm” of vaccines from the WHO-led ACT accelerator, aims to ensure that the next countries gain equivalent, or at least simultaneous, access to Covid-19 vaccines.This is the practical mechanism that translates the often expressed ideal of ‘global solidarity’ into concrete actions; however, its effectiveness will count on the generosity of the richest countries in the world to ensure investment in vaccines for countries that do not.you can’t.
Three other organizations co-led COVAX: the Coalition for Epidemic Preparedness (CEPI), the World Health Organization (WHO) and Gavi, the vaccine alliance.CEPI’s role is to monitor vaccine progression and production so that COVAX has the “largest and maximum diversified portfolio of Covid-19 vaccines.
Gavi leads the “group procurement” mechanism through which COVAX aims to ensure “fair and equitable” access.COVAX will do so using an allocation framework that is being developed through WHO, which is also responsible for defining the policy, such as Tedros in four September that “initially, where the source is limited, priority will have to be given to the vaccination of essential and timely staff, adding the elderly and those with underlying diseases”.
“In vaccine fever, countries can act on their own, creating a few winners and many losers, or they can join,” says CEPI Ceo Richard Hatchett, describing COVAX as “an initiative based on enlightened self-interest but also justice.Gavi CEO Seth Berkley said: “For high-income countries, this is beneficial for everyone: not only will you have guaranteed access to the world’s largest vaccine portfolio, but you’ll also negotiate across a consortium, reducing costs and securing a global access point.»
Meanwhile, money-rich countries are covering their bets by spending billions on “pre-buy” on the diversity of other types of vaccines in development, knowing that some of them may not work (vaccine applicants have traditionally failed at about 90% rate), but depending on the likelihood that at least one of them will.
The UK has signed agreements to download more than 340 million doses of six other vaccines (including the University of Oxford / AstraZeneca vaccine, which is lately in phase III in South Africa, Brazil and the UK). The United States, as a component of its “Warp Speed Operation,” had previously purchased 800 million combined doses (with an option for another $ 1 billion), investing $ 11 billion in the advancement efforts of other seven companies. These also come with vaccine applicants from Oxford / AstraZeneca, Moderna, Pfizer, Johnson
The European Union, whose countries buy in bulk, and Japan has also purchased millions of doses for their entire population (their bet is on doses for each person), the EU pre-buying 400 million doses of the Oxford vaccine.and looking to invest in several others.
Professor Helen Rees, a global and regional vaccine expert chaired by CEPI’s clinical advisory committee and (among other things) the head of the regulator who will eventually certify a vaccine for use in South Africa, said there was highly unlikely that there would be enough vaccines.for everyone in the world until 2022.” It is very likely to have a gradual approach,” he said, “and will be country-specific.”
In an interview with Daily Maverick, Rees explained what it might look like, in the sense of WHO’s recent recommendation: “If you have limited amounts of vaccine and are aware of the efficacy [only] of adult and good-shaped human subjects., We would most likely prioritize frontline fitness staff; however, it is only to talk about how South Africa will do so (this would be a resolution of the Department of National Health, which has not yet explained its long-term policy).for vaccine deployment.)
South Africa’s role in clinical trials
There are approximately two hundred “candidates” for the Covid-19 vaccine in development, 37 are in human clinical trials and nine are in phase III (final phase) in humans.Two of the last nine – Novavax University’s “ChAdOx1 nCoV-19” and Novavax’s “NVX-CoV2373” are currently being tested in South Africa, at various sites in other provinces, in addition to their “domestic” markets (UK and US).And in a small number of other countries, adding Brazil with the highest prevalence (the higher the rate of Covid-19 transmission in a country, faster vaccine trials can show whether a vaccine is working or not).
The South African branches of the trials are led by vacunologist Wits, Professor Shabir Madhi, executive director of the Vaccine and Infectious Diseases Research Unit (VIDA) of the South African Medical Research Council, and who, along with Rees, is co-founder of the African Leadership in Vaccinology Expertise Consortium (ALIVE).
Access to vaccines, as well as others to be prioritized in the event of scarcity, is one of Rees’s biggest considerations, similar to Covid-19 for South Africa, he said.South Africa’s role in overseas trials does not necessarily mean that South Africa will have preferential access to these vaccines, if successful.But, madhi says, South Africa is at least ahead of the curve in generating knowledge about vaccine functionality at the local level, which will speed up our own regulatory process.”advance the advent of a vaccine in low- and middle-income countries (PRFI) until it can demonstrate in this context that a vaccine is working.”(Vaccines would possibly work differently in other contexts, and the arrival of many vaccines in PRFI has been delayed due to lack of data on their effectiveness.)
If the candidate vaccines tested here are effective, the South African Health Products Regulatory Authority (SAHPRA) will act temporarily to certify vaccines for local use.
How COVAX will work
Under COVAX, vaccines will be distributed in a similar manner to all participating countries (WHO allocations will be proportional to the population of countries), starting with fitness staff and expanding to cover the next maximum of vulnerable groups.In total, 78 potentially self-funded countries submitted “expressions of interest” for COVAX, as well as for 92 low- and middle-income countries that WHO defines as eligible for the monetary commitments of self-funded countries (South Africa is not one of them; at the time of publication, the Ministry of Health had not demonstrated that we would “self-finance”).
In addition, COVAX will remain a dose “buffer” for humanitarian and emergency use, adding up to deal with serious outbreaks before they are uncontrollable.
… and will COVAX work?
If COVAX works, it will acquire and deploy vaccines in “sufficient volumes to complete the acute phase of the pandemic until 2021”.
But countries’ participation in COVAX is voluntary, which means that this ideal style of how equitable vaccine distribution can simply paint is based on the resolution of richer countries to vaccinate the poorest through “pre-marketing commitment” (AMC).inspire vaccine brands to produce enough volumes for all countries, sharing the monetary threat to the richest (it is not worth assuming that the United States refused to sign this foreign initiative and will maintain its politicized Operation Warp Speed for itself).
Vaccine production is an expensive activity. COVAX’s good fortune is based on the guarantee across rich countries that poorer countries will access the global “public good” of a vaccine opposed to a global pandemic, so it will only work if self-funded countries and other donors invest.
“Many pharmaceutical corporations invest a lot and do so at risk, because if this product doesn’t work, billions of dollars of investment are lost,” says Rees.
The deadline for countries to deposit their cash where they are, turning “expressions of interest” into binding commitments, is 18 September, and their first initial bills expire by Nine October 2020.
If the initial COVAX target of $2.4 billion is met for studies and progression and the $2 billion “early market share” (AMC) target is met, COVAX will distribute the first 2 billion successful mid-to-past long-term vaccine doses due in 2021 Basically, this will cover vaccines for 20% of the population in all participating countries.
If contributions to either are insufficient, there does not appear to be a contingency plan, or at least no plan that is still in the public domain.Together, the 172 COVAX countries make up 70% of the world’s population, which is at stake.
“Vaccine brands are coming to the party, but the vital thing is that they want money.So it will depend a lot on the countries that invest money,” says Rees.
What does this mean for South Africa?
“If the Oxford vaccine is successful, and since we have contributed to science, if we don’t get it [soon], it will be a big concern,” says Rees.”When it comes to the principles of equity and global reciprocity, those who have been compromised deserve to be identified for it, but there is no guarantee, that is why COVAX is so important.”
But, Rees says there is already a global debate on “vaccine nationalism,” which is critical.”This would possibly not be all for some and none for many others; there will have to be a fair distribution of vaccines.”is that the debate was not left for the end …we have this debate now. DM/MC

Why is the manufacturer’s responsibility factor never addressed?It is not imaginable to ensure the protection of those who take it in the long term …because the long term means it takes a lot of time to assess protection.I suspect Americans will keep their own devices in this case.So why not focus on treating patients instead of injecting other healthy people with ingredients whose protection is unknown?
