Due to the limited supply of vaccinations, achieving herd immunity through efficient use of the vaccines will be a crucial instrument in the fight against COVID-19's widespread prevalence. Here, we examine a variety of vaccination tactics, including a cutting-edge targeted vaccination strategy (EHR), which offers a noticeably greater impact of vaccination on disease transmission than age-prioritized and random vaccination plans. Using high-fidelity individual-based computer simulations with Oslo, Norway as an example, we find that the EHR method achieves herd immunity at 48 percent of the population vaccinated with 90 percent efficiency, whereas the common age-prioritized approach needs 89 percent, and a community reproductive number in a setting where the base pre-vaccination reproduction number R = 2.1 without population immunity.

The typical age-prioritized technique requires 89 percent of the population to achieve herd immunity, while a population-wide random selection approach needs 61 percent. The EHR method achieves herd immunity at 48 percent of the people vaccinated with 90 percent efficiency. We find that age-based techniques struggle to generate herd immunity under most circumstances and have a far smaller effect on epidemic spread. Furthermore, even with perfect vaccinations offering 100% protection, immunizing children is crucial for developing herd immunity.

Explain the role of gelada baboons, walia ibex, and Ethiopian wolves in the Ethiopian Highland ecosystem.
NISA [10]

The role of ice baboons and walia ibex is primary consumer, and ethiopian wolves are secondary consumers in the Ethiopian Highland ecosystem, to understand more about this ecosystem of this beautiful country and its nature.....

<h3>Ethiopian Highland ecosystem</h3>

Situated a few kilometers northeast of the city of Gondar, the park covers 179 square kilometers of mountainous area, with an average elevation of 3,300 meters. Mount Ras Dashan, which is the fourth highest on the mainland and the highest in Ethiopia at 4,550 meters, is located adjacent to the park, they are mountains with grassy fields and forests, although many of these have disappeared.

<h3>Animals</h3>

The Ethiopian wolf is the rarest canid in the world, and Africa’s most threatened carnivore. The gelada is an Old World monkey, not a baboon despite previous naming conventions, the gelada feeds predominantly on fresh shoots of grass, and to a lesser extent on grassroots and seeds.

The walia ibex is found nowhere else in the world except in the Simien Mountains National Park. Walia ibex live on the steep slopes and escarpments of the Simien Mountains, Walias live in groups and forage in open areas. Males and females usually graze separately unless they mate.

With this information, we can say that iced baboons and walia ibex are primary consumer animals, as they feed on producers, and Ethiopian wolves are secondary consumers because they feed on primary consumers.
