As part of measures to keep the population safe, countries have begun rolling out vaccination requirements for international travel. Emerging out of those requirements, however, are concerns that some people, vaccinated with some vaccines, may be prevented from travelling. In Guyana, there have been concerns that the Russian-made Sputnik V vaccine, touted as the backbone of Guyana’s COVID-19 immunisation plan, might prevent people from freely travelling. Some look towards revaccination as a possible solution but health professionals do not agree with this.
