Introduced to the western world in the 18th century, the smallpox vaccine was the first of its kind. As an El Paso newspaper put it in 1910, travelers needed to show one of three things: “A vaccination certificate, a properly scarred arm, or a pitted face” indicating that they had survived smallpox. border with Canada or Mexico, officials expected border-crossers to prove their immunity. Whether at ports of entry including New York’s Ellis Island and San Francisco’s Angel Island, or along the U.S. border officials in the late 19th century did not expect travelers to carry the identification documents that international transit requires today-but they did often require passengers to provide evidence that they had been vaccinated from smallpox.

Hamilton, worked his way down the aisles, asking each passenger, “Been vaccinated?” Unless they had documentation proving that they had been, Hamilton asked them to display their arms, where he looked for a “fresh scar” indicating a recent inoculation. The June 15 VRBPAC is in follow-up to the January 26, 2023, VRBPAC at which FDA discussed the process for determining the need for recommending updates to the composition of COVID-19 vaccines, and the timing for implementation of such an update.įDA will continue to monitor the safety and effectiveness of the COVID-19 vaccines and the evolution of the SARS-CoV-2 virus.Īdditional information: Recommendation for the 2023-2024 Formula of COVID-19 vaccines in the U.S.A southbound passenger train halted in southern Quebec near the Vermont border, where an elderly, bespectacled man boarded the train. Following discussion of the evidence, the committee expressed a preference for XBB.1.5.ĭuring this meeting, the advisory committee was informed of the manufacturing timelines, they reviewed the available data on the circulation of SARS-CoV-2 virus variants, current vaccine effectiveness, human immunogenicity data of current vaccines against recently circulating virus variants, the antigenic characterization of circulating virus variants, animal immunogenicity data generated by new candidate vaccines expressing or containing updated spike components, and preliminary human immunogenicity data generated by one XBB.1.5 candidate vaccine.īased on the totality of the evidence, FDA has advised manufacturers who will be updating their COVID-19 vaccines, that they should develop vaccines with a monovalent XBB 1.5 composition. beginning in the fall of 2023, the committee unanimously voted that the vaccine composition be updated to a monovalent COVID-19 vaccine with an XBB-lineage of the Omicron variant. FDA's Vaccines and Related Biological Products Advisory Committee (VRBPAC) met on June 15, 2023, to discuss and make recommendations for SARS-CoV-2 strain(s) for updated COVID-19 vaccines for use in the United States beginning in the fall of 2023.įor the 2023-2024 formulation of the COVID-19 vaccines for use in the U.S.
