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.
