Vaccine manufacturers are in a race to develop or tweak COVID-19 vaccines to address the Omicron variants that are sweeping through the globe – and get them ready for use as boosters when the weather cools in the northern hemisphere. More infectious Omicron strains BA.4 and BA.5 have become dominant in many parts of the […] Continue reading ->
Two leading researchers who have raised questions about the reliability of Sputnik V’s vaccine efficacy ratings across age groups shared their concerns with Health Policy Watch. One called the results “impossible” and “very concerning”. More than 70 countries have approved the use of Sputnik V, Russia’s COVID-19 vaccine, based on the reported 91.6% efficacy across […] Continue reading ->
The wider use of pooled procurement in national health systems can help low- and middle-income countries get a better deal on pharmaceuticals – here’s how and why. Low- and middle-income countries are making strides in bolstering their domestic pharmaceutical sectors—evidenced by the recent deal between South Africa’s Afrigen Biologics and Belgium’s Univercells, to develop the […] Continue reading ->
WHO and Africa CDC are trying to close a huge testing gap for monkeypox that has left some health workers reliant on symptomatic diagnosis. The World Health Organization (WHO) and African Centres for Disease Control and Prevention (Africa CDC) acknowledge they will not be able to gain a clear understanding of the monkeypox outbreak in […] Continue reading ->
Pfizer and BioNTech have announced positive safety, tolerability and immunogenicity data for two Omicron-adapted COVID-19 mRNA candidate vaccines – but for an earlier strain of Omicron than those that are currently globally dominant. The two Omicron-adapted vaccine candidates were given to 1,234 participants aged 56 years and older as boosters, and “elicited substantially higher neutralizing […] Continue reading ->
Children infected with COVID-19 maintained strong immunity against the virus for at least 18 months, according to a preprint study that was released on Wednesday.

It was 11 November 2022 when Dr Sikhulile Moyo and his team of scientists in Botswana discovered Omicron in a sample of SARS-CoV2 that looked different from the rest. “We sent it back to the lab to have it re-sequenced,” Moyo recalled. But by 19 November, […] Continue reading ->
One year since the establishment of the mRNA Vaccine Technology Transfer Hub, a collaboration between two leading biotech companies – Afrigen Biologics and the Univercells group – was announced on Tuesday, paving the way for the development of the first-ever African-owned COVID-19 vaccine through open-access intellectual property. Using intellectual property from partners, the collaboration between […] Continue reading ->
The first report by the new WHO-convened expert group, Scientific Advisory Group for the Origins of Novel Pathogens (SAGO) has fanned the flames of controversy over evidence about whether a lab leak or a natural “spillover” of the virus from animals to humans was the most likely source from which the COVID pandemic emerged – […] Continue reading ->
Scientists and doctors are beginning to eye Paxlovid, the antiviral medicine developed by Pfizer to protect vulnerable people from severe disease, as a potential treatment for lingering COVID-19 symptoms after single patients report that the medicine has helped to reduce their symptoms. Long COVID affects as many as one in five people infected by the […] Continue reading ->
