Both regimens combine already registered products with new chemical entities (NCEs). The first combines delamanid and bedaquiline with two NCEs, OPC-167832 and sutezolid, while the second includes pretomanid and bedaquiline with the two NCEs. The trials will test whether these regimens can substantially shorten treatment duration, with the goal of advancing a suitable regimen into phase 3 development. UNICEF has awarded GSK a contract valued at up to US$170 million to produce the first malaria vaccine. The award will pay for 18 million doses of GSK’s RTS,S vaccine over the next three years. UNICEF has stated their hopes that the award will encourage other malaria vaccine developers to continue to innovate new technologies in order to address the burden of malaria, especially to mitigate preventable deaths of children under five years old from the disease. The United Nations agency expects high demand for the vaccine and believes that costs per dose will decrease over time as supply and manufacturing capacity grow in turn.On Monday, August 15, the UK Medicines and Healthcare products Regulatory Agency (MHRA) gave conditional approval to Moderna’s Omicron variant-updated COVID-19 vaccine for use as a booster in adults. The approval is based on clinical data that demonstrated “strong immune response” against the original virus and B.A.1 subvariant and exploratory analysis showing a “good immune response” against the B.A.4 and B.A.5 subvariants as well as no serious safety concerns. The UK’s Joint Committee on Vaccination and Immunisation followed by supporting the use of the updated vaccine the national booster shot campaign starting next month.

Named the Langa henipavirus, it causes respiratory symptoms and is closely related to two other human henipaviruses, Hendra and Nipa. While scientists believe the virus is not fatal, nor does it seem to spread easily between humans, experts have urged ongoing surveillance and further research into the virus, especially as zoonotic disease outbreaks become more common worldwide. The virus is believed to be carried by wild shrews although it is unclear whether people are infected directly or indirectly by these animals.Last week, Pfizer and BioNTech announced new trials will start later this month of their updated mRNA vaccine aimed at protecting against the B.A.4 and B.A.5 Omicron subvariants, which have spread quickly and demonstrated heightened ability to evade existing vaccine protection. If the vaccines receive regulatory approval, the companies expect to roll out the updated vaccines by October. The approval process should be quicker than normal as the US Food and Drug Administration (FDA) is not requiring updated clinical data for the B.A.4- and B.A.5-updated shots, instead basing their approval on clinical data from the companies’ Omicron B.A.1-focused vaccine trials, which have already been submitted.The Biden administration is stretching out its limited supply of Jynneos monkeypox vaccine to address the growing public health issue and supply shortage in the face of high demand for the vaccine. On Tuesday, August 9, the FDA issued an emergency use authorization to allow the method of injecting one-fifth of the normal dose amount into the skin rather than a full dose into the fat. The guidance still urges health care providers to continue to follow the regimen of two shots 28 days apart with the lower dose amount. The administration is recommending this method to ensure more high-risk people can access at least some vaccine protection.
