The vaccine that famously got covered by a plastic dome is the smallpox vaccine, specifically during the World Health Organization's (WHO) intensified global eradication campaign in the 1960s and 1970s. In 1977, the last known natural case of smallpox was recorded in Somalia, and to prevent the virus from spreading further, health workers implemented a strategy known as ring vaccination. This involved identifying and vaccinating everyone who had been in contact with an infected person, as well as their close contacts. In a notable instance, a plastic dome was used to isolate and protect a smallpox patient in a hospital in Pakistan, while health workers vaccinated the surrounding population to contain the outbreak. This innovative approach, combined with the plastic dome isolation, played a crucial role in the successful eradication of smallpox, which was officially declared eradicated by the WHO in 1980.
