Challenges of service coordination for evacuees of Hurricane Maria through the National Disaster Medical System.

OBJECTIVE: To describe the challenges of service coordination through the National Disaster Medical System (NDMS) for Hurricane Maria evacuees, particularly those on dialysis. DESIGN: Public health report. SETTING: Georgia. REPORT: On November 25, 2017, there were 208 patients evacuated to Georgia in response to Hurricane Maria receiving NDMS support. Most were evacuated from the US Virgin Islands (97 percent) and the remaining from Puerto Rico (3 percent); 73 percent of these patients were on dialysis, all from the US Virgin Islands. From the beginning of the evacuation response through November 25, 2017, there were 282 patients evacuated to Georgia via NDMS, with a median length of coverage through NDMS for those on and not on dialysis of 60 and 16 days, respectively. CONCLUSION: The limited capacity and capability of dialysis centers currently in the US Virgin Islands are delaying the return to home of many Hurricane Maria evacuees who are on dialysis.

A Plasmodium vivax Plasmid DNA- and Adenovirus-Vectored Malaria Vaccine Encoding Blood-Stage Antigens AMA1 and MSP142 in a Prime/Boost Heterologous Immunization Regimen Partially Protects Aotus Monkeys against Blood-Stage Challenge.

Malaria is caused by parasites of the genus Plasmodium, which are transmitted to humans by the bites of Anopheles mosquitoes. After the elimination of Plasmodium falciparum, it is predicted that Plasmodium vivax will remain an important cause of morbidity and mortality outside Africa, stressing the importance of developing a vaccine against P. vivax malaria. In this study, we assessed the immunogenicity and protective efficacy of two P. vivax antigens, apical membrane antigen 1 (AMA1) and the 42-kDa C-terminal fragment of merozoite surface protein 1 (MSP142) in a plasmid recombinant DNA prime/adenoviral (Ad) vector boost regimen in Aotus monkeys. Groups of 4 to 5 monkeys were immunized with plasmid DNA alone, Ad alone, prime/boost regimens with each antigen, prime/boost regimens with both antigens, and empty vector controls and then subjected to blood-stage challenge. The heterologous immunization regimen with the antigen pair was more protective than either antigen alone or both antigens delivered with a single vaccine platform, on the basis of their ability to induce the longest prepatent period and the longest time to the peak level of parasitemia, the lowest peak and mean levels of parasitemia, the smallest area under the parasitemia curve, and the highest self-cure rate. Overall, prechallenge MSP142 antibody titers strongly correlated with a decreased parasite burden. Nevertheless, a significant proportion of immunized animals developed anemia. In conclusion, the P. vivax plasmid DNA/Ad serotype 5 vaccine encoding blood-stage parasite antigens AMA1 and MSP142 in a heterologous prime/boost immunization regimen provided significant protection against blood-stage challenge in Aotus monkeys, indicating the suitability of these antigens and this regimen for further development.
