Africa could have a Covid-19 vaccine in the first quarter of 2021 if human trials underway in South Africa succeed, a university professor heading the trials said on Thursday.

The ChAdOx1 nCoV-19 experimental vaccine is one of 19 being tested on humans globally in a race to find vaccines to stop a pandemic that has killed more than half a million people so far.

It is also being tested in Brazil by Oxford University scientists who are working with British drugmaker AstraZeneca on development and production.

"A vaccine could be made commercial as early as the beginning of next year," said Shabir Madhi, professor of vaccinology at University of Witwatersrand who is leading the South African trial.

"But it is completely dependent on the results of clinical trials," he cautioned, adding that out of the 19 potential vaccines being tried out, the most positive outcome would be if even two succeed.

The Gauteng Department of Health (GDoH) has moved to explain Health MEC Dr Bandile Masuku's comments on over 1.5 million grave sites being prepared.

On Wednesday, Masuku said more than 1.5 million grave sites were being prepared.

His remarks were made as Covid-19 cases in Gauteng have been increasing sharply.

On Thursday, in a statement, the department said it wanted to clarify the confusion about the number of graves dug for expected Covid-19 deaths.

"The province does not have over a million already open dug graves, the over a million graves refers to the collective capacity municipalities can take," the statement read.

The Department of Health has placed on record that it values the contributions of traditional health practitioners (THP) in the fight against Covid-19, and have asked THP's to refer patients to the next level of care should they present with symptoms of the new coronavirus. 

"THPs play an important role in addressing the burden of diseases in South Africa within the primary healthcare system.

"The message to THPs is to refer patients presenting with symptoms of coronavirus infection to the next level of care," health department spokesperson Popo Maja told News24, adding that traditional medicines/indigenous plants are not excluded by the department from the search for treatments.

Lecturer and PhD candidate in Public Health Pharmacy at the Sefako Makgatho Health Sciences University, Mncengeli Sibanda, said that the World Health Organization (WHO), at an international level, and the government of South Africa, at a local level, are working with stakeholders and research institutions to select vaccines and medicines, and that these include traditional medicines products, which can be investigated for clinical efficacy and safety for Covid-19 treatment.

The High Court in Pretoria will next week hear an application by the Fair Trade Independent Tobacco Association for leave to appeal a ruling that kept cigarettes banned.

"We’ve just received confirmation from the Gauteng Division of the High Court in Pretoria that our application for leave to appeal the ruling of 26 June 2020 dismissing our cigarette ban challenge will be heard on the 15th of July 2020,"said Sinen Mguni, chairperson of FITA, in a WhatsApp message to Fin24 on Thursday.

Cigarettes have been banned since the start of the lockdown in late March. FITA's court challenge to have the ban overturned was dismissed with costs in late June.

FITA had in early July submitted an application for leave to appeal the initial ruling that kept tobacco products banned, arguing the court made a number of errors in its reading of the Disaster Management Act, among other points.

Latest news:

The World Health Organisation on Thursday released new guidelines on the transmission of the novel coronavirus that acknowledge some reports of airborne transmission of the virus that causes Covid-19, but stopped short of confirming that the virus spreads through the air.

In its latest transmission guidance, issued on Thursday, the WHO acknowledged that some outbreak reports related to indoor crowded spaces have suggested the possibility of aerosol transmission, such as during choir practice, in restaurants or in fitness classes.

How frequently the coronavirus can spread by the airborne or aerosol route - as opposed to by larger droplets in coughs and sneezes - is not clear.

But the WHO said more research is "urgently needed to investigate such instances and assess their significance for transmission of Covid-19."

In just over seven months, there have been more than 11 million cases of the novel coronavirus that causes Covid-19 globally.

As the pandemic progresses, scientists are investigating how new strains develop, as this will tell us more about how the virus is spreading, and how it could affect vaccine development.

Now, new research from Sheffield University, published in the journal Cell on 6 July 2020, has shown that a new mutation of the viral genome of Covid-19 has improved its ability to infect human cells, according to a news release.

This means that the virus spreads more easily without necessarily being deadlier.

As the Covid-19 pandemic progresses, we're getting to understand a bit more about the various factors that can increase your risk of severe Covid-19 infection. This includes comorbidities such as diabetes, hypertension and age.

Now, a new study published on 7 July in pre-print form in the American Journal of Gastroenterology, found in a survey of more than 86 000 people that a common heartburn drug, known as proton pump inhibitors (PPI), can increase the risk of Covid-19 infection.

From the survey, led by scientists from Cedars-Sinai Medical Centre, more than 53 000 of the 86 000 participants suffered from acid reflux, heartburn or regurgitation, and took medication for these conditions. Out of these people, more than 3 300 tested positive for Covid-19.

After analysing the data, the scientists found that those participants who used PPI to treat their conditions were two to four times more likely to test positive for Covid-19.

HEALTH TIPS (as recommended by the NICD and WHO)

• Maintain physical distancing – stay at least one metre away from somebody who is coughing or sneezing

• Practise frequent hand-washing, especially after direct contact with ill people or their environment

• Avoid touching your eyes, nose and mouth, as your hands touch many surfaces and could potentially transfer the virus

• Practise respiratory hygiene – cover your mouth with your bent elbow or tissue when you cough or sneeze. Remember to dispose the tissue immediately after use.
