COVID-19 vaccination intention among Venezuelan migrant populations in Colombia, 2021.

Dear Editor,

One key aspect for control of the Coronavirus Diseases 2019 (COVID-19) pandemic is vaccination. This is related to multiple factors (e.g. availability), but especially to vaccine hesitancy and intention. In the recent article from Urrunaga-Pastor et al. [1], they describe a COVID-19 vaccine intention of 80% in a large Latin American sample. Whilst we agree on its importance, we would like to discuss our assessment of a particularly complex and vulnerable subpopulation, Venezuelan migrants in Colombia.

We conducted three random sample-based community surveys among Venezuelans in Cucuta, Norte de Santander department (surveys in the El Talento and Comuneros barrios) and Pasto, Nariño department (one survey), Colombia, to gather relevant information to be used to target effective communications to this population about COVID-19 and COVID-19 vaccine. Norte de Santander department, on the northeast border with Venezuela, is the major point of entry into Colombia from Venezuela. Nariño department, located on the southwest border with Ecuador, is the major point of exit for Venezuelans across the international border. Surveys included 926 respondents (Table 1 ). Eleven focus groups were conducted concurrent with surveys. Fieldwork was conducted in late August and early September 2021. Vaccine availability for Venezuelan migrants in Colombia was very limited at that time, but has recently become broader.

Among survey respondents, more than 51% considered that COVID-19 vaccine is too new or that social media make them feel unsure about it (Table 1). Between 3.7% (Comuneros, Cucuta) and 26.4% (Pasto) of respondents do not trust the government about vaccine (Table 1). However, from 19.9% (Pasto) to 54.4% (El Talento, Cucuta), answered that someone in their households had already been vaccinated (Table 1). Of greater importance, from 74.7% (El Talento, Cucuta) to 91.6% (Comuneros, Cucuta), said that they would be vaccinated when the vaccine becomes available for them (Table 1). Moreover, large majorities, from 71.7% (El Talento, Cucuta) to 94.1% (Pasto), will follow the advice of doctors regarding COVID-19 vaccination (Table 1). During focus groups, a lack of legal documentation (i.e., not being “regular”) was cited as the biggest barrier to vaccination. Focus group participants were aware of a wide variety of false information concerning COVID-19 vaccine and treatment, though they tended not to accept it. Concern about vaccination during pregnancy was very common.

The survey data on vaccine plans, practices, and opinions are promising in this vulnerable Venezuelan migrant population (Table 1). Although negative opinions are common, the majority of households at all three assessed sites either had someone vaccinated already or have plans to when the vaccine is available. There appears to be little firm opposition to the vaccine, as seen in the United States and elsewhere [[1], [2], [3], [4]]. This is consistent with beliefs that COVID-19 is genuine and of concern. Nevertheless, the household prevalence of a lack of confidence that the vaccine is effective suggests that public education still has a substantial opportunity to raise the ultimate vaccination level [[1], [2], [3]].

The distribution of opinions about the vaccine (Table 1) shows the power and thought penetration of adverse social media posts, greater than 50% in all three sites [2,3]. The relatively recent development of vaccines is in these three communities a common concern, just as it is in the United States and elsewhere. Side effects, whether general or specific, also appear to be a highly prevalent concern [5]. These findings make the importance of an effective communications plan of obvious importance. Given these common opinions, it is perhaps remarkable that vaccine hesitancy appears to be as uncommon as it does (Table 1).

While there is substantial awareness of inaccurate information about the vaccine and less than effective, or even dangerous, preventive measures, doctors remain a generally trusted source of information, guidance, and treatment [3]. These data suggest that doctors should be utilized to educate the public about the benefits of vaccination and to convince their patients to be vaccinated. This is especially important among migrant populations. Migrants’ knowledge of vaccine benefits was deep and broad, including things like opening schools, reducing the severity of COVID-19 disease, and preventing spread through the community.

The most significant barrier to vaccination was the need for documentation to be “regular.” That came up in several places and contexts. However, the distribution of COVID-19 vaccines has changed substantially in the following months since fieldwork was performed. At that time, the vaccine had just been made available, at least officially, to Venezuelans who were documented or pregnant. In the recent weeks before this letter was prepared, eligibility was expanded to include undocumented migrants on a supply-available basis. In addition, in the past several days, the government announced that all Venezuelans would be vaccinated equally with Colombians as soon as Colombian children are vaccinated. However, as of the date this letter is submitted, planning for vaccination of undocumented persons is difficult because supply for them is uncertain until the very last moment. It appears that undocumented Venezuelans continue to be treated differently from other persons in Colombia. However, it is likely that this will change soon as the government has recognized that everyone must be protected to protect the country as a whole. Like other reports, this one highlights the importance of Venezuelan migrant populations in Colombia over the recent years [6].
