How the exam will ask it
പ്രിലിംസ്
- Ervebo is a vaccine approved against the Zaire strain of Ebola virus.
- Cross-protection means a vaccine against one strain may also protect against a related strain; the DRC trial will test this for Bundibugyo ebolavirus.
- Ebola is a viral haemorrhagic fever caused by viruses of the genus Orthoebolavirus, with several distinct species including Zaire and Bundibugyo.
- The Democratic Republic of the Congo is the site of the planned WHO-announced human trial.
മെയിൻസ്
GS-III (Science and Technology, health) and GS-II (international organisations). Issue: vaccines exist for only one Ebola species, leaving outbreaks of other strains such as Bundibugyo without a licensed vaccine. Policy: WHO-coordinated trials in affected countries test whether an approved vaccine gives cross-protection. Implication and way forward: faster ring-vaccination readiness, stronger surveillance and equitable access to vaccines, with India building its own outbreak preparedness and research capacity.
