Analysis

Spain’s vaccination recommendations for migrants and refugees arriving through irregular routes have generated a politicised backlash. Posts frame the strategy as proof that migrants are bringing diseases previously eliminated in Spain, including polio, and argue that taxpayers are being required to finance preferential healthcare for people who entered the country irregularly.

The strategy is intended to provide rapid access to selected vaccinations when immunisation records are missing or when previous access to healthcare may have been interrupted. Online commentary removes this operational context and presents the policy as evidence that migration itself constitutes a biological threat.

References to polio, measles and other vaccine-preventable diseases are combined with claims about border control, public expenditure and unequal access to services. Some posts do not oppose vaccination directly. Instead, they use vaccination policy to support broader anti-migrant narratives and distrust of health institutions.

The narrative could undermine immunisation in two directions. Host communities may interpret catch-up vaccination as evidence that authorities are concealing an uncontrolled disease threat or prioritising migrants over citizens. Migrants and refugees may fear that accessing vaccination will identify them to authorities or reinforce the perception that they are carriers of disease.

This framing is relevant beyond Spain. Similar narratives may emerge in countries managing refugees, displaced populations, nomadic groups or cross-border movement associated with polio outbreaks. Stigmatising mobile communities can reduce cooperation with vaccination teams, delay care-seeking and make surveillance more difficult.
