The global pandemic has highlighted fragility in international supply chains and the dependency of many African countries on imported personal protective equipment (PPE). Market pressures have also increased prices for imported supplies and put additional pressure on areas with limited resources for... procurement. There is an urgent operational need to develop the domestic capacity to supply PPE from within the African continent. There is huge variation in Member
States industrial manufacturing capacity and the regulatory and testing capacity of government agencies at present. Growing number of companies, including micro- and small-medium enterprises, have responded by repurposing, albeit temporarily, to manufacture an assortment of PPEs. This workshop aims to bring together government representatives, industry, and subject matter experts on material testing and standards to promote the development of domestic production of safe and effective PPE made in Africa.

Serum Institute of India Pvt. Ltd. [COVISHIELD™, ChAdOx1 nCoV-19 Corona Virus Vaccine (Recombinant)]
Efficacy shown in clinical trials in participants who received the full series of vaccine (2 doses) ir...respective of interval between the doses was 63.1%, based on a median follow-up of 80 days, but tended to be higher when this interval was longer. The data reviewed at this time support the conclusion that the known and potential benefits of ChAdOx1-S/nCoV-19 [recombinant] vaccine outweigh the known and potential risks.

Diphtheria is caused by Corynebacterium species, mostly by toxin-producing Corynebacterium diphtheriae and rarely by toxin-producing strains of C. ulcerans and C. pseudotuberculosis. The most common type of diphtheria is classic respiratory diphtheria, whereby the exotoxin produced characteristicall...y causes the formation of a pseudomembrane in the upper respiratory tract and damages other organs, usually the myocardium and peripheral nerves. Acute respiratory obstruction, acute systemic toxicity, myocarditis and neurologic complications are the usual causes of death. The infection can also affect the skin (cutaneous diphtheria). More rarely, it can affect mucous membranes at other non-respiratory sites, such as genitalia and conjunctiva.
C. diphtheriae is transmitted from person to person by intimate respiratory and direct contact; in contrast, C. ulcerans and C. pseudotuberculosis are zoonotic infections, not transmitted person-to-person. The incubation period of C. diphtheriae is two to five days (range 1– 10 days). A person is infectious as long as virulent bacteria are present in respiratory secretions, usually two weeks without antibiotics, and seldom more than six weeks. In rare cases, chronic carriers may shed organisms for six months or more. Skin lesions are often chronic and infectious for longer periods. Effective antibiotic therapy (penicillin or erythromycin) promptly terminates shedding in about one or two days.
