Machine learning for optimizing daily COVID-19 vaccine dissemination to combat the pandemic

The World Health Organization (WHO) declared the coronavirus outbreak in Wuhan, China, in December 2019 as COVID-19, designating 2020 as the year of global disaster [1]. Since the first fatality from the disease was recorded in January 2020, before vaccination began in the United Kingdom on December 8th, the number of confirmed and death cases has progressively increased (UK). The virus spreads from person to person, resulting in a worldwide epidemic. COVID-19 is a virus that causes mild symptoms in persons of various ages [2, 3].

While data indicates that two categories of persons are much more likely to be infected by this serious virus than some others: the aged (over 60 years old) and those who are habitually sick as a result of congestive heart failure, diabetes, acute pulmonary, and cancer problems. The number of confirmed cases is dropping fast in nations where vaccines have started, such as the United States and the United Kingdom, whereas it is still rising or constantly changing in places where immunizations have begun late or not at all. Because the death toll from COVID-19 has been steadily rising over the world [4], many countries have been compelled to take more drastic measures, such as masking, social distancing, isolation, and restriction. The creation of the COVID-19 vaccines as soon as possible has become a worldwide concern. In 2022, sufficient COVID-19 vaccines are expected to be manufactured to immunize a minimum of 70 percent [5]. Based on the most recent research, there is a quantity that might halt the global epidemic years earlier than projected if the vaccines are well circulated.

Due to their great efficiency, machine learning (ML) techniques are now widely employed in a wide range of computer applications [6, 7]. Empirical methods such as data mining and machine learning, for example, might help. Machine learning classification algorithms are data processing methods that make it easier to create closed-form mathematical models [8, 9]. Machine learning classification algorithms are data processing techniques that make the building of analytical models easier. Data mining is used to create rules from massive amounts of data. Machine learning is crucial in today’s environment, especially in healthcare. Machine learning techniques are being used to help with hospital system restructuring, infectious disease detection and treatment, and medical treatment [10‐13]. In addition, machine learning models may be used to give intelligent solutions for analyzing vast amounts of data.

By building rapid and effective algorithms and models based on actual observations of the process for real-time data processing, machine learning approaches are able to give outstanding outputs and analysis. As a result, more information must be provided to medical workers so that they may make educated judgments regarding medical diagnosis and treatment approaches while also being aware of the potential consequences and costs for everyone [14]. The ability of machine learning to generate massive datasets beyond human competence is critical in healthcare. Following that, machine learning reliably transforms data analysis into the knowledge of the disease and its symptoms, as well as the necessity for therapy. This will help healthcare workers plan and deliver treatment, resulting in improved results, fewer healthcare costs, and more patient satisfaction [15, 16].

The importance of ML in healthcare is its proficiency in generating large datasets over and above human capacity. Afterward, ML dependably transforms the analysis of that data into awareness of the disease and its symptoms, and the need for treatment. This will aid healthcare providers in planning and delivering care, resulting in improved results, lower healthcare costs, and more patient satisfaction [15, 16].

To optimize the daily COVID-19 vaccine so as to fight against the pandemic, we obtained data from Kaggle and analyzed it using machine learning algorithms [17]. ML algorithms are used for extracting useful information from data and building a reliable predictive model from it. Machine learning algorithms [18‐21] are used in this study to improve vaccination and determine which is the most successful in terms of consistency and accuracy. The objective of this paper is to apply predict about the acceptability of COVID-19 vaccines and study their predictors.

This research contribution is summarized as follows:

The remainder of this work is structured as follows: Section two discusses relevant work, section three discusses methodology, part four discusses findings and discussion, and the conclusion is presented in section five.

Kim [22] used two statistical models and a deep learning (DL) model and (LSTM-DNN) to model and forecast daily verified coronavirus cases (COVID-19). The stacked long short-term memory deep neural network was employed in conjunction with the autoregressive integrated moving average (ARIMA), the generalized autoregressive conditional heteroscedasticity (GARCH), and the autoregressive integrated moving average (ARIMA). The experiment uses ten datasets provided by the WHO. Simulation results reveal that performance is based on the dates and vaccinations utilized in the data. It also reveals that the proposed LSTM-DNN prediction is superior to the two statistical models. According to the experimental data, LSTM-DNN significantly improves mean absolute error when compared to ARIMA and GARCH. ARIMA and GARCH yield different outcomes based on the dataset. The achieved results could serve as a benchmark for the COVID-19 daily confirmed cases' performance limits and prediction accuracy. The shortcoming of the work is that data collected after February 2021 was not included in the analysis. Furthermore, the accuracy of the proposed model is quite poor.

Cheong et al. [23] used machine learning techniques to examine socioeconomic data from a range of online sources, including the US CDC and the US Census Bureau COVID-19 Site. Using XGBoost and socioeconomic data, a machine learning study was done. With a 62 percent accuracy rate, the suggested model accurately predicted COVID-19 vaccination uptake in US countries. It was also observed that the most important socioeconomic determinants determining vaccine uptake in the United States include region, education, ethnicity, income, and home internet access. Finally, the algorithm generated a themed map depicting low and high vaccination rates, which health care officials might utilize in future pandemics to visualize and prioritize low vaccination zones as well as organize specific vaccine programs. The experiment had a flaw in that the dataset only included data from the United States, resulting in poor prediction accuracy.

Machine learning techniques were used by Abdulkareem et al. [24] to assess the progress of COVID-19 immunization throughout the world. The findings of the article indicated which method is superior for which dataset. To assess and generate findings, four output classification strategies were used: Decision Tree (DT), K-nearest neighbors (KNN), Random Tree (RT), and Naive Bayes (NB), with ML models on Weka. According to the research, DT outperforms other algorithms in terms of speed and precision. The experiment performance was not compared with other machine learning algorithms utilizing the same dataset, which is a flaw in the work. Moreover, the performance of many of the ML models used except for the decision tree is poor.

Fernandes et al. [25] used machine learning approaches to predict COVID-19 vaccination and the factors that influence vaccines. The study’s major purpose was to look at people’s intentions to be vaccinated and to vaccinate their children. They also wanted to know how their decision was impacted by personal qualities, emotional concerns, and the lockdown scenario. As a result, during the Portugal shutdown, the authors conducted an online survey (15 January 2021 until 14 March 2021). According to the data, 63% of the 649 participants said they were highly likely to obtain the vaccination and 60% said they would vaccinate their children. The trials employed linear regression models, which explained 65 percent of the variation in individual immunization and 56 percent of the variance in group immunization. The overall ideas and attitudes about the COVID-19 vaccine were revealed to be the most important drivers of vaccination intention. Furthermore, the recommended artificial neural network (ANN) model achieved a vaccination intention prediction accuracy of 85%. The drawback of the work is the prediction accuracy is low. Also, the work did not cover data obtained after 14 March 2021.

To evaluate the general predilection to the COVID-19 vaccination, Zaidi et al. [26] used five models. A voting classifier was used to determine the accuracy of all the classifiers at the completion of their research. According to the data, a Support Vector Machine (SVM) generates the best predictions, whereas an Artificial Neural Network (ANN) produces the worst predictions for individual capacity to be vaccinated with the COVID-19 vaccine. The proposed technique has an overall accuracy of 89.9% for the random dataset and 45.7 percent for the date-wise dataset when employing the voting classifier. As a result, the results reveal that the proposed prediction technique is a valid and promising method for predicting future COVID-19 vaccination trends. The suggested work has a flaw in that the total forecast accuracy is low.

Using previously available data, Davahli et al. [27] created sequence-learning models to estimate the behavior of the COVID-19 pandemic across the United States (US). They classified US states based on their resemblance to previously reported COVID-19 behavior to avoid training the models for all states. The researchers employed an unsupervised self-organizing map to divide all states in the United States into four groups based on the similarity of their effective reproduction numbers. They developed deterministic and stochastic long short-term memory (LSTM) and mixed density network (MDN) models after selecting a leading state (the state with the earliest recorded occurrences) in each group. Data was added into the model from each leading state, which was then compared to a baseline linear regression model to predict future outcomes. They investigated the effects of removing periodicity and patterns from a dataset of non-stationary COVID-19 events on prediction. Alternative prediction strategies beat the deterministic LSTM model trained on the COVID-19 ideal reproduction numbers, according to their findings. The work shortcoming is that the data used is exclusively from the United States. Furthermore, the authors did not take into account the interaction of states. Finally, the study data set is limited to only three months from August 26, 2020, to November 26, 2020. Table 1 summarized the list of all related works.

Motivated by gaps and the benefit mentioned above, Elastic Net (ENET), CUBIST, Gaussian Process (GAUSS), and Spikes and Slab (SPIKES) methods are developed for the prediction of COVID-19 vaccination in Africa, Asia, Europe, South America, North America, and Oceania. To the best of our knowledge, this is the first-time prediction of the COVID-19 vaccine in combating COVID-19 diseases in the continents of the world is explored.

Vaccines are the most important instrument for bringing the pandemic to an end and saving lives and livelihoods. It is critical that everyone has equal access to immunizations that are both safe and effective. There is no one who is safe until everyone gets vaccinated. In the fight against COVID-19, safe and effective COVID-19 vaccinations are a game-changer. Figures 2–12 is the roll-out of COVID-19 vaccines for each country of the World. Figure 2 consist of twenty countries in Africa that have commences vaccine of its citizen. Egypt and Algeria commenced vaccination of its citizen earlier than other country while Chad and Burkina Faso commenced late in the vaccination chart. The country that first commenced COVID-19 vaccination among them are Seychelles and Mauritius while three countries commenced late and these are Madagascar, Liberia and Guinea Bissau as shown in Fig. 3. Out of the twelve countries in Fig. 4, South Africa and Zimbabwe commenced vaccination earlier than others while Zambia, Tanzania and Somalia commenced vaccination of their citizen late. Out of twenty countries in Asia, China, Kuwait and Bahrain commenced vaccination earlier while Kyryzstan, Brunei and Armenia commenced late in the vaccination of their citizen (as shown in Fig. 5). Out of twenty-one countries in Fig. 6, Qatar and Oman commenced vaccination earlier than others while Yemen and Tajikistan commenced late in the vaccination of its citizen. Almost all the countries in Fig. 7 commenced vaccination of its citizen earlier except Georgia, Faeroe Islands and Bosnia and Herzegovia that commenced vaccination late. Out of twenty-one of this countries Moldova, Kosovo and Jersey commenced vaccination of its citizen late than other countries (as shown in Fig. 8. Figure 9 consists of eight countries in Oceania which include Vanuatu, Papua New Guinea, New Zealand, New Caledonia, French Polynesia, Fiji and Australia. Out of the eight countries in Oceania, two countries commenced vaccination earlier and these are New Caledonia, French Polynesia. Figures 10, 11, 12 consists of countries in South America that commences vaccination. It was observed Canada, USA, Mexico, Chile and Argentina commenced vaccination earlier.

In this research, the outcomes of machine learning approaches such as CUBIST, Spikes and Slab (SPIKES), Gaussian Process (GAUSS), and Elastic Net (ENET) were studied. The four machine learning algorithms used in this study were compared to determine which was more accurate in predicting daily COVID-19 immunization. The Kaggle database was used to get the COVID-19 dataset. We demonstrate the accuracy of these methods in predicting daily COVID-19 vaccination using Mean Absolute Scaled Error (MASE), Relative Absolute Error (RAE), and Mean Squared Log Error (MSLE). Figures 13, 14, 15, 16 is the result of both real and predicted COVID-19 vaccination of all the four machine learning considered in this paper.

MASE, RAE, and MSLE are among the performance measures shown in Table 4. CUBIST surpasses the other three algorithms by attaining lower error rates, implying that the methods are more precise than any other forecast. According to the data, CUBIST can predict daily COVID-19 immunization.

A study was carried out for the prediction of daily COVID-19 to reduce disease propagation. The study presented and used four well-known machine learning models for daily COVID-19 prediction: CUBIST, Gaussian Process (GAUSS), Elastic Net (ENET), and Spikes and Slab (SPIKES). According to the findings of the study, CUBIST have the ability to predict daily COVID-19 immunization. As the findings demonstrate, selecting the best successful model for this prediction requires a combination of performance indicators such as Relative Absolute Error (RAE), Mean Squared Log Error (MSLE), and Mean Absolute Scaled Error (MASE). CUBIST can predict daily COVID-19 immunization in Asia with 9.7368 (MASE), North America with 2.8901 (MASE), Oceania with 13.2169 (MASE) and South America with 3.9510, respectively. Furthermore, findings showed that different nations in Europe begin immunizing their citizens earlier than other continents.

However, the limitation of this research is that obtaining COVID-19 datasets of those who are fully vaccinated is extremely difficult due to the fact that social media is awash with posts denigrating the vaccine hesitant. This has resulted in many people being unwilling to receive COVID-19 vaccination. The consequence is something of a social media cultural war, with many online commentators suggesting that vaccine skeptics are altering their minds, yet even a delay is considered a hazard to health because viral diseases spread swiftly. In the future, we will examine various machine learning techniques to assess daily COVID-19 vaccination.
