Summary

This summary is machine-generated.

COVID-19 vaccine adverse events (AEs) were common, particularly local reactions and pain, across six Arabic countries. Older age and male gender were associated with increased AEs after the first dose.

Area Of Science

  • Public Health
  • Epidemiology
  • Vaccinology

Background

  • The COVID-19 pandemic presented significant global health challenges, necessitating widespread vaccination efforts.
  • Concerns regarding the safety and adverse events (AEs) of COVID-19 vaccines have emerged.
  • Understanding vaccine AEs is crucial for maintaining public trust and vaccine uptake.

Purpose Of The Study

  • To investigate the incidence and types of adverse events following COVID-19 vaccination.
  • To identify factors associated with the occurrence of adverse events.
  • To assess the risk of post-vaccination COVID-19 disease with different vaccine types.

Main Methods

  • A cross-sectional study involving 1564 participants was conducted in six Arabic countries between January 1-22, 2022.
  • A validated, self-administered Arabic questionnaire collected sociodemographic data, vaccination history, and experienced AEs.
  • Multistage sampling was employed, including random selection of governorates and urban/rural areas within each country.

Main Results

  • Local AEs were most frequent after the first (67.9%), second (46.6%), and third (45.7%) doses. Bone pain, myalgia, and fever were also common.
  • Johnson and Johnson, Sputnik Light, and Moderna vaccines showed higher AE frequencies.
  • Increased age (61-75 years) and male gender were associated with higher odds of AEs after the first dose.
  • Sinovac, Sinopharm, and Johnson and Johnson vaccines were associated with higher rates of post-vaccination COVID-19.
  • Pre-vaccination SARS-CoV-2 infection significantly increased the risk of post-vaccination COVID-19 across all doses.

Conclusions

  • Adverse events following COVID-19 vaccination are common, with local reactions being the most prevalent.
  • Specific vaccines (Johnson and Johnson, Sputnik Light, Moderna) were associated with a higher frequency of AEs.
  • Factors like age, gender, and prior infection influence AE occurrence and post-vaccination disease risk.
  • Further research is needed to provide more generalizable data on the safety of various COVID-19 vaccines.

Surveys 02:16

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Surveys allow researchers to gather data from larger samples than may be afforded by...

Cross-reactivity 00:42

31.1K

Overview

The ability of a single antibody to recognize multiple structurally similar epitopes is an important immune defense strategy that enables the host to efficiently defend against many potentially threatening pathogens. However, cross-reactivity also elicits allergy symptoms against related allergens. It is increasingly important to understand the principles of cross-reactivity, as antibodies are actively being developed as therapeutic modalities for diverse diseases, including cancer.

Vaccinations 01:51

44.5K

Overview

Vaccination is the administration of antigenic material from pathogens to confer immunity against a specific microorganism. Vaccination primes the immune system to recognize and mount an immune response faster and more effectively if the real pathogen is encountered. Vaccinations are one of the most efficient ways to protect both individual humans and the general public from disease. A growing anti-vaccination skepticism risks the successes of vaccination programs that helped reduce...

Local Anesthetics: Adverse Effects 01:12

414

While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...
