Abstract
Background and Objectives: Vaccine acceptance could seriously affect global efforts to control the Covid-19 pandemic. The aim of this study was to estimate the Covid-19 vaccine acceptance and its related factors in Tehran and Kermanshah.
Methods: A population-based cross-sectional study was conducted on 850 participants in Tehran and Kermanshah using the random digit dialing method. Multiple logistic regression was used to estimate the adjusted odds ratio of factors related to vaccine acceptance.
Results: The frequency of the Covid-19 vaccine acceptance was 66.47% (95% confidence interval: 69.57%, 63.21%). Moreover, 86.02% of the participants stated that they would use any type of (Iranian / foreign) vaccine approved by the Iranian Ministry of Health. However, 13.98% of the participants stated that they only preferred foreign approved vaccines (if available). The variables of age, fatalism, and socioeconomic status had significant associations with the Covid-19 vaccine acceptance.
Conclusion: Based on the results of this study, the Covid-19 vaccine acceptance was moderate. In order to achieve herd immunity by vaccination faster in our society, the strategy of prioritizing vaccination can be planned based on the related variables such as religious beliefs and fatalism, younger age groups, and people with higher socio-economic status that are willing to receive the vaccine.

Abstract
Background and Objectives: Using a random sample of women aged 15 to 50 years in Tehran, this study sought to estimate the lifetime prevalence of abortion (intentional and unintentional) and to identify its associated factors.
Materials and Methods: The control data of a population-based case-control study conducted in 2014 in Tehran was used in the present study. Data from 544 randomly selected women aged 15-50 living in municipality areas of Tehran were included in this study. A multiple logistic regression model was used to investigate factors associated with abortion and to estimate the adjusted odds ratios (ORs) and 95% confidence intervals.
Results: Overall, 102 women (18.8%, 95% CI (22.4% -15.8%)) reported a lifetime history of abortion. In the logistics regression model, being single (OR =3.46, 95% CI: 1.42-8.47) older age (OR = 1.07, 95% CI: 1.04-1.11) increased the odds of a positive lifetime history of abortion. However, having a child (OR = 0.27, 95% CI: 0.11-0.65)), more education years (OR = 0.89, 95% CI: 0.82-0.96)) and higher religious beliefs (OR = 0.65, 95% CI: (0.45-0.93)) decreased the odds of a positive lifetime history of abortion..
Conclusion: High reported lifetime prevalence of abortion in the present study and its subsequent risks to maternal health highlight the need for educational interventional programs taking into account the level of education and knowledge of mothers along with their religious.

Abstract
Background and Objectives: Serological studies are based on the detection of antibodies. However, the produced antibodies decrease over time; therefore, such methods cannot provide a valid estimate of prevalence and incidence. The present study aimed to determine the serum prevalence and cumulative incidence in the Ravansar cohort population (Youth and RaNCD Cohort) in October 2020.
Methods: A random sample of 716 people aged > 18 years old were selected from the participants in the Ravansar cohort study in October 2020. Euroimmun anti-SARS COV-2 IgG ELISA kits (Lübeck, Germany) were used to measure antibody levels. Seroprevalence was estimated with considering of cut-off = 1, and cumulative incidence (modified and modified based on test specificity) was determined using modeling.
Results: In the present study, the serum prevalence of COVID-19 viral infection in the Ravansar cohort population from 22 October 2020 to 18 November 2020 was estimated to be %35.16 (95%CI: %31.64, %38.79). Modified Cumulative incidence and modified based on test characteristics from 20 February to 18 November 2020 were estimated to be %68.85 and %67.71, respectively.
Conclusion: Although very high cumulative incidence may be a sign of approaching herd immunity, adherence to health protocols is still recommended due to the potential role of asymptomatic cases in transmitting the disease to other members of the community; and the presence of new variants of the virus and reduced antibody levels should be considered.
