Short-term side effects of COVID-19 vaccines: A cross-sectional study in Jordan

Impact of Comorbidities and Skin Diseases on Post-Vaccination Reactions: A Study on COVID-19 Vaccinations in Poland

Background: The COVID-19 pandemic necessitated rapid and widespread vaccination efforts, which proved critical in reducing the severity and mortality of the virus. However, the interplay between vaccinations, pre-existing skin conditions, and other comorbidities still needs to be explored. This study investigated the occurrence and severity of adverse events following immunization (AEFIs) with COVID-19 vaccines in individuals with chronic skin diseases and comorbidities within a Central European cohort. Methods: An anonymous online survey was conducted between May 2022 and February 2023, targeting students and employees of universities in Wrocław, Poland. A total of 513 respondents were analyzed, focusing on AEFIs following the first, second, and third doses of COVID-19 vaccines and the effects of COVID-19 on conditions such as atopic dermatitis, psoriasis, vitiligo, acne vulgaris, rosacea, and various comorbidities. Results: COVID-19 vaccination effectively protected against severe disease across all doses. The analysis revealed no significant impact of either COVID-19 infection or vaccination on the course of selected skin diseases and comorbidities. The reporting of AEFIs to the Sanitary Inspection was notably low. The Moderna and Pfizer mRNA-based vaccines were associated with a higher reported number of AEFIs, particularly after the second and third doses, compared to AstraZeneca, which exhibited fewer adverse events after subsequent doses. Conclusions: COVID-19 vaccination is both safe and effective, even in patients with pre-existing skin conditions and comorbidities. Vaccine selection may benefit from considering individual health profiles, and better reporting of AEFIs is needed to enhance vaccine safety monitoring.

Incidence of narcolepsy symptoms after taking COVID-19 vaccines: a Jordanian cross-sectional study

Purpose

Sleeping disorders were reported in many patients who took vaccines during previous pandemics. We aim to investigate the relationship between coronavirus disease 2019 (COVID-19) vaccines and the incidence of narcolepsy symptoms in the Jordanian population.

Materials and Methods

We used a descriptive, cross-sectional, online self-administered survey conducted between December 2022 and May 2023. The survey targeted males and females above the age of 18 years who took any type of COVID-19 vaccine, had no chronic diseases, and had no sleep disorders prior to taking the vaccine. The survey was distributed via social media platforms.

Results

A total of 873 participants were included in this study, consisting of 44.4% males and 55.6% females, with the majority being in the 18-29 age group. Most participants (79.8%) received two vaccine doses, with the Pfizer vaccine being the most common. Nearly half of the participants reported excessive daytime sleepiness. Sleep paralysis and hypnagogic hallucinations were reported by a notable proportion of participants, but no significant differences were found among the vaccine types. Sleep attacks and fragmented nighttime sleep were associated with the number of vaccine doses received, suggesting a possible influence of the dose count on these symptoms. The presence of excessive daytime sleepiness, sudden loss of muscle tone, sleep paralysis, and hypnagogic hallucinations showed no significant association with the number of doses taken.

Conclusion

We hypothesize a possible link between COVID-19 vaccination and the emergence of narcolepsy symptoms in Jordanian individuals. Additional investigations and continuous monitoring to determine the extent of the risk and uncover potential mechanisms behind this connection should be performed.

Undesirable effects of COVID-19 vaccination on Saudi population: A descriptive study, Winter 2022

Objective

The development of coronavirus disease 2019 (COVID-19) vaccines was a crucial preventative measure toward controlling the pandemic. Several side effects have been reported. This study investigated the long-term side effects reported by the Saudi population. post-COVID-19 vaccination.

Methods

The cross-sectional study involved Saudi participants of both genders, aged ≥16 years, and had received at least one dose of any of the available vaccines in Saudi Arabia. They were asked to fill out an online questionnaire divided into three sections: Demographics, medical history, and side effects that appeared post-COVID-19 vaccines.

Results

The findings indicated that the undesirable effects were reported by 82% of the participants. These side effects involve three categories: The most common, additional or reported, and persistent side effects. The most common side effects were pain at the site of injection (88.16%), bone pain/joint pain (68.7%), and fatigue (68.46%). Menstrual disorders (n = 46), hair loss (n = 34), and memory problems (n = 19) were reported by participants as additional side effects. Among all side effects, fatigue, joint pain, hair loss, and menstrual disorders were the most persistent side effects. Moreover, 190 participants reported that they were diagnosed with diseases soon after receiving the COVID-19 vaccine including COVID-19, thyroid gland disorder, and irritable bowel disease. The quality of life of some of the participants was affected by post-COVID-19 vaccines, as 25.28% had anxiety, 21.22% had depression, and 33.16% had discomfort.

Conclusion

These findings may contribute to understanding the effect of COVID-19 vaccines on the Saudi population's health and public opinion about these vaccines.

BACKGROUND

The safety of the COVID-19 vaccines has been a topic of concern globally. This issue of safety is associated with vaccine hesitancy due to concerns about the adverse effects of the vaccines. Consequently, this study determined the short-term safety profile of the Oxford/AstraZeneca COVID-19 vaccine in Ekiti State, Nigeria.

METHODS

Descriptive cross-sectional study conducted between May and July 2021 among individuals who had received the first dose of the first batch of the Oxford/AstraZeneca COVID-19 vaccine at Ekiti State University Teaching Hospital (EKSUTH), Ado-Ekiti, Nigeria. A Google form was used to collect data on the adverse effects of the vaccine.

RESULTS

Out of over 1,000 individuals who were approached, 758 respondents completed the study. A large percentage (57.4%) of those who received the vaccines were healthcare workers. Adverse effects were reported in 70.8% of the participants with most manifesting on the first day of the vaccination. The predominant adverse effects were injection site soreness (28.5%), followed by fatigue (18.7%) and muscle pain (8.6%). There was no report of severe adverse effects such as anaphylactic reactions, thrombosis, myocarditis, transient myelitis, or Guillen-Barre syndrome.

CONCLUSION

This study found that self-reported adverse effects of the Oxford/AstraZeneca COVID-19 vaccine were mild and short in duration. This outcome has promising implications for improving COVID-19 vaccine uptake in the immediate environment and Nigeria.

Association between COVID-19 vaccines and development of chronic morbidities: a cross-sectional study in the Jordanian population

BACKGROUND

In Jordan, individuals recently diagnosed with chronic illnesses have expressed concerns with regard to COVID-19 vaccines. This study aims to investigate potential associations between COVID-19 vaccination and the likelihood of recipients developing chronic conditions such as autoimmune diseases, rheumatoid arthritis, diabetes, asthma, and hypertension.

METHODOLOGY

Through a cross-sectional survey-based descriptive approach, this research was conducted to gather data within the Jordanian context. A web-based survey was utilized to collect demographic information, record vaccine-related side effects, and document the chronic disease status subsequent to COVID-19 vaccination. Statistical analysis was employed to reveal any potential associations between the vaccine, its side effects, and the emergence of chronic morbidities.

RESULTS

The study involved 414 participants, among whom 10.4% exhibited pre-existing chronic diseases before vaccination. Remarkably, post-vaccination, 23.7% of participants were newly diagnosed with chronic illnesses. Statistical analysis indicated a significant correlation between COVID-19 vaccination and the subsequent development of chronic diseases (p-value ˂.01). the investigation found no significant association between vaccination and the emergence of diabetes, hypertension, or asthma (p-value ≥.01) However, an association was found between COVID-19 vaccination and the development of autoimmune diseases and rheumatoid arthritis (p-value ˂.01).

CONCLUSIONS

This study highlights an association between the occurrence of autoimmune diseases and COVID-19 vaccination, while findings related to diabetes, asthma, and hypertension did not display significant associations. The results emphasize the necessity for further research to ascertain potential causal relationship.

Self-reported side effects of COVID-19 vaccines among the public

Background

The safety, side effects and efficacy profile of COVID-19 vaccines remain subjects of ongoing concern among the public in Malaysia. The aim of this study was to determine the types of adverse effects following immunisation with COVID-19 vaccines and the differences based on various types of COVID-19 vaccines to raise public awareness and reduce vaccine hesitancy among the public.

Methods

A total of 901 Malaysian adults (≥18 years) who received various COVID-19 vaccines were selected to participate in our cross-sectional study through an online survey between December 2021 and January 2022.

Results

A total of 814 (90.3%) of the participants reported ≥1 side effect following COVID-19 immunisation. Of these, the predominant symptoms were swelling at the injection site (n = 752, 83.5%), headache (n = 638, 70.8%), pain or soreness at the injection site (n = 628, 69.7%), fatigue or tiredness (n = 544, 60.4%), muscle weakness (n = 529, 58.7%) and diarrhea (n = 451, 50.1%). Recipients of the Pfizer-BioNTech (Comirnaty ®) vaccine reported the highest number of adverse effects (n = 355, 43.6%), followed by mixed COVID-19 vaccines (n = 254, 31.2%), the Oxford-AstraZeneca (ChAdOx1-®[recombinant]) vaccine (n = 113, 13.9%) and the Sinovac (CoronaVac®) vaccine (n = 90, 11.1%). The study showed that individuals who reported significantly more side effects were of elderly age, female gender and high educational level [P value < 0.05]. Mixed COVID-19 vaccine recipients also reported significantly more local and systemic symptoms after the first dose and third dose when compared with other single vaccine recipients.

Conclusion

This study demonstrated the types of self-reported adverse effects following immunisation with single and mixed COVID-19 vaccines. These findings may provide the side effects of different COVID-19 vaccines with the hope of educating the public on the safety profiles of these vaccines and reducing vaccine hesitancy among the public.

Assessing the prevalence and patterns of COVID-19 vaccine side effects among Syrian adults: A cross-sectional study

Aim

This study aimed to assess the prevalence and patterns of COVID-19 vaccine side effects among Syrian adults, with a focus on the AstraZeneca and Sputnik Light vaccines, in light of the low vaccination rate in Syria (below 18%) attributed to fear of side effects.

Method

A cross-sectional study was conducted between January and May 2022, using probability-based and convenient sampling strategies. Data was collected through online, paper, and face-to-face questionnaires that included demographic and vaccine-related questions.

Result

Out of 3,766 participants, the majority were female (56.7 %) and aged 18-24 years (53.3 %). Most participants had a university-level qualification (71.2 %) and were related to the medical sector (53.2 %). A significant proportion (47.0 %) received AstraZeneca, Sputnik Light (22.1 %) and Sinopharm (14.7 %). Common side effects included sleepiness and lethargy (50.0 %), fever and chills (45.0 %), and pain/swelling at the injection site (35.9 %). Multivariate logistic regression analysis revealed that male (OR: 0.57, CI: 0.48-0.68) and participants aged 45-65 years (OR: 0.53, CI: 0.40-0.70) were less likely to experience side effects. Participants who believed COVID-19 posed a high threat to their personal life had higher odds of side effects (OR: 1.74, CI: 1.22-2.46). Vaccine type was also associated with side effects, with Sputnik Light (OR: 2.52, CI: 1.85-3.46) and AstraZeneca (OR: 1.61, CI: 1.26-2.05) having increased odds.

Conclusion

Our study found that COVID-19 vaccines are well tolerated among the Syrian population, with short-term side effects that typically resolve within three days. These findings are expected to bolster vaccination rates through enhanced public confidence and acceptance.

Side effects of COVID-19 vaccines in the middle eastern population

The COVID-19 pandemic has caused severe worldwide health concerns since its first description as the SARS-COV-2 virus in December 2019. The wide dissemination of this virus, together with the lack of treatment, prompted vaccine development within a short period of time to elicit a protective immunity against COVID-19. Due to their rapid development, potential subsequent side effects of COVID-19 vaccines were overlooked, which might lead to many health concerns. This is especially true for patients at a greater risk of harm from COVID-19, such as pregnant women, children, and patients with pre-existing chronic diseases. In this review, we provide a summary of common to rare side effects of administrated COVID-19 vaccines in a Middle Eastern population. We have found that the distinction between side effects from COVID-19 vaccines in terms of frequency and severity is attributed to the differences in study populations, gender, and age. Pain at the injection site, fever, headache, fatigue, and muscle pain were the most common reported side effects. Vaccinated subjects with previous COVID-19 infection exhibited an equivalent neutralizing response after just one dose compared to two doses of vaccine. Consequently, individuals who experienced more side effects had significantly higher antibody levels. This indicates that having better immunity correlates with higher antibody levels, leading to a higher frequency of vaccine side effects. Individuals with underlying comorbidities, particularly having known allergies and with illnesses such as diabetes and cancer, might be more prone to post-vaccination side effects. Studies of a high-risk population in Middle Eastern countries are limited. Future studies should be considered to determine long-term side effects, side effects after booster doses, and side effect differences in cases of heterologous and homologous vaccination for better understanding and proper handling of high-risk populations and patients who experience these side effects.

A qualitative assessment of the adverse effects associated with COVID-19 vaccines: a study from Jordan

OBJECTIVES

The current study aimed to qualitatively explore the side effects reported by participants who received the COVID-19 vaccine among the Jordanian population.

METHODS

Between April 18th and May 12th, 2022, an in-depth interview was conducted with a purposive sample of vaccinated individuals to assess the side effects of the COVID-19 vaccine in this study. Thematic analysis was used to identify themes and sub-themes within the current qualitative data.

RESULTS

A total of 20 participants were interviewed. They had a mean age of 41.3 (SD = 14.3) years. Half of the participants were females (n = 10, 50.0%). The study revealed six main themes: first, most of the respondents believed that COVID-19 vaccines were safe. Second, the vaccines are not equivalent in their safety. The third there showed that participants follow preventive measures to decrease the possibility of experiencing side effects. The fourth theme showed that reporting of side effects by the participants is dependent on the experienced side effects. Moreover, the next theme revealed that participants showed hesitancy to take more than one type of vaccine. Finally, participants were willing to take the vaccine annually, because they believed that the vaccine is better than the disease itself and decreases the aggressive effects of the disease.

CONCLUSIONS

This study found that the majority of participants believed in the safety of the COVID-19 vaccines and emphasized the responsibility of the healthcare providers in increasing awareness among the population about the importance of the vaccines. Enhancing such awareness is essential to improve the acceptance of receiving different types of vaccines.

Effectiveness of Nutritional Supplements for Attenuating the Side Effects of SARS-CoV-2 Vaccines

Supplementation is known to enhance the immune response and reduce infection. Therefore, the association between immune nutrients and vaccine side effects needs to be investigated. Our aim was to analyze the relationship between vaccination side effects and supplement intake among the Italian population. The study included a questionnaire asking for personal data, anthropometric information, COVID-19 infection and immunity response, and COVID-19 vaccination and supplementation. The survey was conducted from 8 February to 15 June 2022. In the study, 776 respondents were included, aged between 18 and 86 (71.3% females). We observed a statistically significant correlation between supplement consumption and side effects at the end of the vaccination cycle (p = 0.000), which was also confirmed by logistic regression (p = 0.02). Significant associations were observed between supplement intake and side effects of diarrhea and nausea at the end of the vaccination cycle (p = 0.001; p = 0.04, respectively). Significant associations were observed between side effects and omega-3 and mineral supplementation at the start of the vaccination cycle (p = 0.02; p = 0.001, respectively), and between side effects and vitamin supplementation at the end of the vaccination cycle (p = 0.005). In conclusion, our study shows a positive impact of supplementation on vaccination response, increasing host immune defenses, and reducing side effects.

Short-term Side Effects of mRNA-based COVID-19 Vaccine Among Jordanian Population; a Cross-sectional Study

Introduction

One type of the developed COVID-19 vaccines that received emergency permission and was approved by the food and drug administration (FDA) is the mRNA-based vaccine. The aim of this study is to gather information on the Jordanian population's experience with the vaccine's side effects.

Methods

The study objectives were addressed through a cross-sectional study, which collected information regarding the short-term side effects experienced by the vaccinated individuals within one month following the injection of an mRNA-based COVID-19 vaccine. Data collection was carried out in August 2021. Participants were invited to take part in a self-administered web-based survey created using Google Forms.

Results

Among the study's participants (n= 533), about 56% experienced side effects after the first dose of the mRNA-based COVID-19 vaccine. The most commonly reported side effects after the first dose were sore arm at the injection site (91.6%), and fatigue (83.06%). The female gender was significantly associated with experiencing fatigue, discomfort, chills, and hair loss. Being over 30 years old was significantly associated with experiencing cough. Being a smoker was significantly associated with experiencing shortness of breath and gastrointestinal symptoms.

Conclusion

The mRNA-based COVID-19 vaccine side effects were common, yet, mild, local, and self-limited. The local pain at the injection site was the most commonly reported side effect. Hopefully, the study's findings will aid in lowering resistance to vaccination.

Web-Based Reporting of Post-Vaccination Symptoms for Inactivated COVID-19 Vaccines in Jordan: A Cross-Sectional Study

BACKGROUND

The perception of COVID-19 vaccines as being unsafe is a major barrier to receiving the vaccine. Providing the public with accurate data regarding the vaccines would reduce vaccine hesitancy.

METHODS

A cross-sectional study was conducted to collect data on the side effects experienced by the vaccinated population to assess the safety of the inactivated COVID-19 vaccine.

RESULTS

The majority of the study participants (n = 386) were female (71.9%), and 38.6% of them were under 30 years old. Around half of the participants (52.8%) reported side effects after receiving the inactivated COVID-19 vaccine. Fatigue (85.1%), a sore arm at the site of the injection (82.1%), and discomfort (67.2%) were the most commonly reported side effects after the first dose. Reporting side effects was significantly associated with the female sex (p-value = 0.027). Significant associations between being female and experiencing chills, muscle or joint pain, anorexia, drowsiness, and hair loss were also found, as well as being above the age of 30 and experiencing a cough. Being a smoker was significantly associated with experiencing a cough, and a headache. Furthermore, chills, and a sore throat were significantly associated with individuals who had not been infected before.

CONCLUSION

Mild side effects were reported after receiving the inactivated COVID-19 vaccine. Fatigue was the most commonly reported side effect. Females, older adults, smokers, and those who had never been infected with COVID-19 had a greater susceptibility to certain side effects.
