COVID-19: Vaccine Hesitancy in Africa and the Way Forward

Omeiza Lukman Ahmed, Azad Abul Kalam, Kozak Kateryna, Mafo Abaniwo Rose, Mamudu Ukashat, Oseyemen Daniel Aikhonmu

Problemy Ekorozwoju

Vol. 17, nr 2

COVID-19 pandemic took the world by storm in late 2019, scientists and health authorities across the globe struggle to contain the deadly virus. Socio-economic activities across the globe were partly halted as countries around the world introduce various forms of restrictions to contain the spread of the COVID-19 virus. Most developing countries’ economies, especially in Africa, slid into recession, unemployment among Africa countries skyrocketed to an all-time high, and famine and starvation were beginning to knock harder on poorer nations around the world. The race to develop a vaccine was pressing harder; developed countries continue to pump more money to help develop a vaccine within the shortest period of time, as that seems the only viable solution to the economic downturn of the global world. Finally, vaccines were developed and proved to have high efficacy. This has helped reverse the negative trend of the global economy caused by the COVID-19 pandemic. This vaccine faced a lot of global scrutinies; people have refused to get vaccinated and have also rejected the idea of making COVID-19 vaccination compulsory for citizens worldwide. This study analyzes the challenges posed by this ugly trend of COVID-19 vaccine hesitancy in African countries, its socio-economic consequences and the way forward.

Prace Romana Nitscha z zakresu wścieklizny na tle rozwoju mikrobiologii jako dyscypliny medycznej na przełomie XIX i XX w.

Roman Franciszek Henryk Nitsch was born on September 5, 1873 in Podchybie. In 1899, he graduated from the Faculty of Medicine of the Jagiellonian University. Until 1915, he worked as an assistant in the Department of Hygiene of the Jagiellonian University in Krakow, cooperating with Prof. Odon Bujwid. In 1915 he was nominated as an associate professor of hygiene and bacteriology. In 1920, he was appointed full professor of bacteriology at the University of Warsaw. For the rest of his life, he was associated with the research center in Warsaw. He died on 29 March 1943. Roman Nitsch’s scientific activity, which mainly involved his research on vaccination against rabies, is a significant contribution to the development of Polish medical microbiology. The analysis of Roman Nitsch’s scientific achievements proves that he was a continuator of Ludwik Pasteur’s and Odon Bujwid’s - his predecessor and teacher - research thought, as well as the author of pioneering works that shed new light on the world of microbes, which was then only gradually being discovered.

Simultaneous determination of thimerosal and aluminum in vaccines and pharmaceuticals with the use of HPLC method

A simple and convenient chromatographic method of simultaneous separation, identification, and quantitative determination of thimerosal (TM) (preservative) and aluminum (adjuvant) in vaccines and pharmaceuticals by reversed phase highperformance liquid chromatography (RP-HPLC) with visible (VIS) detection was developed and validated. Due to postcolumn derivatization with dithizone, any interference from matrix was excluded. Similarly, a possibility of on-column decomposition of dithizonates was eliminated. Evaluated detection limits were 0.3 μg TM and 3.0 μg Al, which correspond to the smallest, but possible to recognize, visible peak.
