疫苗接种对COVID-19疾病进展的影响

Effect of Vaccination to COVID-19 Disease Progression

Randy L. Caga-anan, Michelle N. Raza, Grace Shelda G. Labrador, Ephrime B. Metillo

摘要:

开发了具有最小隔室的COVID-19数学模型。该模型非常简单,可以拟合确诊病例的数据,估计隐藏的感染数字,并考虑疫苗接种的影响。考虑到新变异的影响,该模型与菲律宾确诊病例数据拟合良好。用拟合的参数,结果表明,如果电流传输率增加约5%,预计将出现第二个峰值,其幅度与第一个峰值惊人地相似,如果它将增加到20%,则已经是一个完全的灾难。然后,该模型被用来估计时间,以实现群体免疫考虑自然免疫力被感染和疫苗接种计划的国家。结果表明,如果实现每天20万人接种疫苗的计划,那么到2022年3月可以实现群体免疫。但如果只实现一半,时间可能会延长到2023年2月。

英文摘要:

A mathematical model of COVID-19 with minimal compartments is developed. The model is simple enough to fit data on confirmed cases, estimate the hidden infection figure and incorporate the effect of vaccination. With the effect of the new variant being considered, the model fits well with Philippine data of confirmed cases. With the fitted parameters, results show that a second peak, strikingly similar in magnitude to the first, is to be expected if the current transmission rate is increased by about 5\% and already a complete disaster if it will go up to 20\%. The model is then used to estimate time to achieve herd immunity considering natural immunity from being infected and vaccination plan of the country. Results show that if the plan of 200,000 vaccinated people per day is achieved then herd immunity can be attained by March 2022. But if only half of that is achieved the time could go up to February 2023.
