Healthcare workers were prioritized in vaccination campaigns globally because they are exposed to the highest risk of contamination by SARS-CoV-2. This study evaluated the self-reported post-vaccination side effects of inactivated (BBIBP-CorV and CoronaVac) and adenoviral vector-based (AZD1222, Gam-COVID-Vac and Ad26.COV2.S) vaccines among Algerian healthcare workers using a validated questionnaire. The final analysis included 721 healthcare workers, with a predominance of females (59.1%) and younger individuals 20–30 years old (39.4%). Less than half (49.1%) of the respondents reported at least one local side effect, while 53.8% reported at least one systemic side effect. These side effects were more prevalent among viral vector vaccinees than inactivated virus vaccinees. The most common local side effects were injection site pain (39%) and arm pain (25.4%), while fatigue (34.4%), fever (28.4%), headache (24.8%) and myalgia (22.7%) were the most prevalent systemic side effects. The side effects appeared earlier among inactivated virus vaccines recipients and generally lasted for 2 to 3 days for the two vaccinated groups. The risk factors associated with a higher prevalence of side effects included female gender, allergic individuals, individuals with regular medication, those who contracted the COVID-19 disease and those who received two doses for both inactivated and viral-based vaccines groups. Despite the higher prevalence of post-vaccination side effects among adenoviral vector vaccines recipients, both vaccines groups were equally effective in preventing symptomatic infections, and no life-threatening side effects were reported in either vaccine group.

Background and Study Aim. There is no doubt that the Coronavirus disease (COVID-19) pandemic, and its related containment measures such as lockdown and social distancing, is affecting physical activity and sleep quality  of the general population worldwide. Algeria, one of the most affected countries in Africa, entered the lockdown on March 9, 2020. Numerous studies have explored the interaction between physical activity and sleep quality showing the effect of physical activity levels on sleep, yet previous researches have not investigated the relationship between physical activity and sleep quality during lockdown. The main purpose of the present study was to investigate the association between physical activity and sleep quality in quarantined individuals. Material and Methods.  A national Google online survey was conducted between 16th April and 25th May 2020. 1002 Participants responded to the Pittsburgh Sleep Quality Index (PSQI) questionnaire and the short form of the International Physical Activity Questionnaire (IPAQ). Of the 1002 participants who completed the survey, 358 were students. The final data were collected from the respondents. Results. The COVID-19 home confinement led to a decrease in physical activity levels. However, the majority of the study population had good sleep quality (61.9%), while only (38.1%) had poor sleep quality. In addition, women are less physically active than men (p < 0.01). Moreover, there was a significant difference in sleep quality between sufficient and insufficient physical activity groups (p < 0.05). Conclusions. Our results show that Algerian adults have low levels of physical activity, good sleep quality, and poor sleep quality is associated with insufficient physical activity in adults during lockdown.
