Vaccination currently appears to be the only strategy to contain the spread of COVID-19. At the same time, vaccine hesitancy (VH) could limit its efficacy and has, therefore, attracted the attention of Public Health Systems. This systematic review aimed at assessing anti-COVID-19 vaccine acceptance rates worldwide and at identifying populations more prone to vaccine hesitancy, for which specific interventions should be planned. PubMed database was searched using a purposely formulated string. One hundred out of the 9243 studies retrieved were considered pertinent and thus included in the analyses. VH rate was analyzed according to patient geographical origin, ethnicity, age, study setting, and method used for data collection; data from specific populations were separately analyzed. Overall, this study demonstrated significant differences in terms of VH in the general population and in the specific subgroups examined according to geographical, demographic factors, as well as associated comorbidities, underlining the need for purposely designed studies in specific populations from the different countries, to design targeted programs aimed at increasing awareness for confidence and complacency toward COVID-19 vaccines.

“…The acceptance rate of the Covid-19 vaccine in this study (62%) was lower compared to the average acceptance rate in Mexico reported in a global survey conducted in 19 countries in June 2020 (76.2%) and lower than the global average (71.5%). 14 However, as the global survey was not nationally representative, we cannot rule out the possibility of selection bias. Another nationally representative survey among Mexican adults conducted in November 2020 reported an acceptance of 82%; how-ever, this figure included both answers, "definitely will get vaccinated" and "unsure, but probably will get vaccinated", which in our case were considered hesitant.…”

“…This is different to other countries where the elders are more likely to accept the Covid-19 vaccines. 14,16,17 This finding is particularly worrisome, considering the burden of morbidity and mortality experienced by older adults, particularly men, in Mexico. 1 A previous study reported that the main determinant for refusal in the elderly is the perception of Covid-19 severity, 18 which suggests that Mexican elders could be having a lower perception of disease severity, although the true underlying cause cannot be explored with our data.…”

Acceptance, refusal and hesitancy of Covid-19 vaccination in Mexico: Ensanut 2020 Covid-19

Objective. To estimate the willingness to vaccinate against Covid-19 (acceptance) in the Mexican population and to identify socioeconomic factors associated with vaccine hesitancy and refusal. Materials and methods. We estimated the acceptance, refusal and hesitancy proportions using data from the Covid-19 National Health and Nutrition Survey conducted from August to November 2020. Factors associated with refusal and hesitancy were explored using multinomial logistic regression. Results. Covid-19 vaccination acceptance was 62.3%, refusal 28.2% and hesitancy 9.5%. Refusal and hesitancy were associated with being female, having older age, lower educational level, lower socioeconomic status and working in the informal sector. Conclusion. National campaigns to incentivize vaccine acceptance need to consider specific subgroups were the likelihood of hesitancy and refusal is high. In Mexico, refusal and hesitancy were higher in vulnerable groups, and people at a higher risk of Covid-19 complications and death.

“…Identifying factors associated with COVID-19 vaccine refusal may assist in developing strategies to reduce vaccine hesitancy. To identify demographic factors associated with COVID-19 vaccine acceptance, Lazarus et al [ 7 ] surveyed individuals in 19 countries and reported that individuals who reported a high degree of trust in the government were more likely to report vaccine acceptance than those with low trust. In the United States, a survey study by the US Census Bureau showed that 49% of respondents were reluctant to receive a COVID-19 vaccine.…”

“…The increasingly common practice of using the internet to obtain health care information makes it possible to study commonly held medical concerns by examining searching patterns and behaviors. Previous studies have documented the prevalence of COVID-19 vaccine hesitancy in the United States [ 8 , 15 ] and globally [ 7 ], but none of these studies explored the content of COVID-19 vaccine concerns evidenced by internet searching. Moreover, the quality of COVID-19 vaccine information resulting from internet searching has yet to be investigated.…”

Background The emergency authorization of COVID-19 vaccines has offered the first means of long-term protection against COVID-19–related illness since the pandemic began. It is important for health care professionals to understand commonly held COVID-19 vaccine concerns and to be equipped with quality information that can be used to assist in medical decision-making. Objective Using Google’s RankBrain machine learning algorithm, we sought to characterize the content of the most frequently asked questions (FAQs) about COVID-19 vaccines evidenced by internet searches. Secondarily, we sought to examine the information transparency and quality of sources used by Google to answer FAQs on COVID-19 vaccines. Methods We searched COVID-19 vaccine terms on Google and used the “People also ask” box to obtain FAQs generated by Google’s machine learning algorithms. FAQs are assigned an “answer” source by Google. We extracted FAQs and answer sources related to COVID-19 vaccines. We used the Rothwell Classification of Questions to categorize questions on the basis of content. We classified answer sources as either academic, commercial, government, media outlet, or medical practice. We used the Journal of the American Medical Association’s (JAMA’s) benchmark criteria to assess information transparency and Brief DISCERN to assess information quality for answer sources. FAQ and answer source type frequencies were calculated. Chi-square tests were used to determine associations between information transparency by source type. One-way analysis of variance was used to assess differences in mean Brief DISCERN scores by source type. Results Our search yielded 28 unique FAQs about COVID-19 vaccines. Most COVID-19 vaccine–related FAQs were seeking factual information (22/28, 78.6%), specifically about safety and efficacy (9/22, 40.9%). The most common source type was media outlets (12/28, 42.9%), followed by government sources (11/28, 39.3%). Nineteen sources met 3 or more JAMA benchmark criteria with government sources as the majority (10/19, 52.6%). JAMA benchmark criteria performance did not significantly differ among source types (χ24=7.40; P=.12). One-way analysis of variance revealed a significant difference in mean Brief DISCERN scores by source type (F4,23=10.27; P<.001). Conclusions The most frequently asked COVID-19 vaccine–related questions pertained to vaccine safety and efficacy. We found that government sources provided the most transparent and highest-quality web-based COVID-19 vaccine–related information. Recognizing common questions and concerns about COVID-19 vaccines may assist in improving vaccination efforts.
