“…Then we tested the hypotheses that "There is a significant co-occurrence of symptoms in reporting side-effects, indicating that the tweets are more likely to contain multiple symptoms simultaneously". To test this hypothesis, we calculated the correlation between the symptoms using a Spearman's correlation coefficient, which is used to determine the relation between two sets of data [43], the formula is shown in (5). Where, p is the correlation coefficient, di is the difference between the ranks for each observation, and N is the sample size.…”

“…Including, BNT162 (Pfizer-BioNTech) developed by Pfizer and BioNTech, ChAdOx1 (AstraZeneca) developed by AstraZeneca and the Oxford Vaccine Group at the University of Oxford, mRNA 1273 (Moderna) by Moderna, and Ad26.COV2-S by Johnson & Johnson [4]. There are also other vaccines were authorized only in emergency cases namely, Sputnik V (Gamaleya) designed by Gamaleya in Russia, CoronaVac by Sinovac, BBIBP-CorV developed by Beijing Institute of Biological Products/Sinopharm, and COVAXIN (Bharat Biotech) developed by Indian pharmaceutical company Bharat Biotech in collaboration with Indian Council of Research (ICMR) and National Institute of Virology (NIV) [5].…”

Vaccines might potentially cause side effects as any other drugs, which need to be investigated and analyzed to identify the public safety concerns. The massive vaccination rollout against COVID-19 provoked discussion among people through social media platforms. Twitter (X), a popular social media platform, plays a significant role in disseminating information about COVID-19 vaccines and monitoring people's reports regarding vaccination side effects. The aim of this study is to mine Twitter (X) to identify self-reported side effects related to COVID-19 vaccines in Arabic language, compare their distribution among six vaccine types, and construct Arabic lexicon of symptoms. We collected the tweets posts in Arabic language after the distribution of COVID-19 vaccines, then we developed a workflow for identifying selfreport symptoms using biterm topic modeling (BTM) and support vector machine (SVM) to extract the symptoms then cluster them in groups based on their co-occurrence. A total of 51 symptoms were extracted from 65,387 tweets that were reported 148,324 times. We performed a more in-depth analysis to investigate the symptoms that tend to occur simultaneously. The results show that the symptoms that more likely to occur together may indicate to a particular connection. The findings suggested that the social media conversation can provide a comprehensive depiction of symptoms that may complement what identified in clinical studies.

Should We Recommend Routine Revaccination Against COVID-19 to Our Cardiac Patients?

A well-researched review on adult vaccinations by Dr Sudhir Sinha in this issue of IJCC prompted me to pen a few lines on the need for regular (? yearly) revaccinations against COVID-19, in view of the apparent fading away of the disease around us. The pandemic began in November 2019 and within 12 months, effective vaccines could be introduced which proved beneficial in reducing deaths and severity of disease significantly. Since their first use in mid-January, 2021, in India itself 94% population received 1 dose and 86% received a second dose due to a mega vaccination drive. 1 Due to the cumulative effect of vaccine-efficacy and immunity due to natural infection, the disease burden receded globally. Fortunately, the recent variants of COVID-19 are less virulent. People have thrown away the masks and forgotten social distancing; life is as usual like in prepandemic days everywhere. Now we are left with the dilemma of whether vaccines are still relevant in these changed conditions. If vaccines have to continue, whether the whole population has to receive booster doses on a regular basis like influenza vaccination, or should we protect the most vulnerable sub-sets.World Health Organization (WHO) has approved about 15 vaccines for emergency use like Pfizer/BioNTech, Oxford/ Astra Zeneca, Johnson and Johnson, Moderna, Covilo, Novavax, Covovax, Spikevax, Can Sino, Comirnaty, and CoronaVac in a short span. Their acceptance was fairly satisfactory for the first and second doses. After that, the vaccine hesitancy started with reports of a few adverse effects-some real and some unrelated. As cardiologists, we are keen to learn about the cardiac events following COVID vaccination. An elegant review of case reports by Paknahad et al. is worth reading. The most common cardiac event was myocarditis with an incidence of 1.62%. The majority of them had mRNA vaccines (Moderna & Pfizer). Men were more frequently affected especially after the second dose. Inactivated vaccines had the least incidence of cardiovascular events. A higher incidence of thrombotic thrombocytopenia and pulmonary emboli was noted after mRNA vaccines compared to other type of vaccines. These authors concluded that the public health and personal benefits of COVID-19 vaccinations outweigh the cardiac risk events. 2
