Five patients developed corneal allograft rejection after immunization. One patient, a 33-year-old woman, received a tetanus toxoid booster nine months after a corneal transplant for keratoconus. Within four days she developed a graft rejection that required a penetrating keratoplasty two years later. Six months later, after hepatitis B immunization, the patient reported decreased vision and the graft was cloudy, but visual acuity was 20/20. The other four patients developed graft rejection after influenza immunization. Two of these four graft rejection episodes were successfully treated with high-dose corticosteroid therapy; all episodes occurred within several weeks of influenza immunization. Patients should be prudently counseled regarding the possible risks of immunization to corneal allograft survival.

In the course of a prospective study of the prevalence and incidence of infection with the human immunodeficiency virus (HIV) and risk factors for the acquired immune deficiency syndrome among 961 homosexual men, 97 initially HIV antibody seronegative men reported a febrile period lasting at least three days. In 60 of these men serological evidence for an infection was found: influenza A or B virus (17 men), HIV (14), Epstein-Barr virus (seven), parainfluenza virus type I, 11 or Ill (five), hepatitis A virus (three), cytomegalovirus (three), adenovirus (two), respiratory syncytial virus (two), hepatitis B virus (one) and Toxoplasma gondii (one). Combined infections were found in five men. A total of 17 men seroconverted for HIV antibody. The clinical symptoms of acute HIV infection closely resembled those of influenza A or B infection. Skin rashes also occurred frequently in men with HIV infection. HIV antibody seroconversion gives rise to a number of different symptoms and primary HIV infection should be included in the differential diagnosis of prolonged febrile illness in those at risk of HIV infection.

The evolution of viral vaccines from the time of Jennerian prophylaxis to today's recombinant technology has been a continuing story of success. From the relatively crude or "first generation" vaccines for smallpox, rabies, and yellow fever followed a second and third generation of improved or new viral vaccines. The application of techniques for attenuating, inactivating, and partially purifying candidate viruses yielded safe, effective vaccines against influenza, poliomyelitis, measles, mumps, and rubella. With the advent of effective national immunization programs in the United States and other areas of the world to promote wide scale use of these vaccines, we have seen a dramatic decrease in incidence of the viral infections of childhood. The new biotechnology serves as the cornerstone for a fourth generation of vaccines and has already provided a licensed recombinant yeast human hepatitis B vaccine. The prospects for a wide spectrum of new or improved vaccines are highly encouraging, not only because of the recent technical advances but also because vaccine development has been recognized as a priority area of research. Under the National Institute of Allergy and Infectious Diseases' Program for Accelerated Development of New Vaccines, support is being provided for developmental vaccine studies with hepatitis A and B, influenza A and B, rabies, rotavirus, varicella, and respiratory syncytial virus (53). The outlook for antivirals is equally optimistic. The same technologies that have provided greater insight into the genetics and molecular biology of viruses and hence the means to fashion subunit or even synthetic vaccines have yielded data that can be applied to successful development of targeted antiviral compounds.

Thirty male patients (27 homosexual) with biopsy proven chronic active hepatitis B were randomised to receive lymphoblastoid interferon (Wellferon) or no treatment. All patients were HBeAg positive and had continuing viral replication. Patients receiving treatment were given a single daily intramuscular injection of interferon for 28 days at a starting dose of 2.5 MU/m2 increasing to a maximum of 7.5 MU/m2/day. Transient side effects of malaise and influenza like symptoms occurred in all patients and resolved rapidly after treatment. Hepatitis B viral replication was suppressed during interferon treatment in all patients but the effect was limited to the period of therapy. After one year there was no appreciable difference in viral markers between the two groups of patients and this treatment schedule appears less effective than the thrice weekly, three month regimes recently reported from other centres.

In 1984 a rare opportunity arose to document the effects of contact on a previously isolated population in Papua New Guinea. The Hagahai, a small group of hunter-horticulturalists, remained hidden from government and mission influence until the early 1980s. Prior to that time, indirect contact through trade with neighboring peoples facilitated the entry of introduced infectious diseases. In late 1983 the Hagahai sought medical aid at a mission station, an event which accelerated their contact with the common epidemic diseases of the highlands. A wide variety of genetic, linguistic, ethnographic and medical data have been collected which document the historical sequence of events contributing to the current rapid demographic decline among the Hagahai. Serological evidence demonstrates the endemicity of Bancroftian filariasis, malaria, C. diphtheriae, cytomegalovirus, HTLV-1, the Ross River arbovirus and several viruses associated with the common cold. Recent epidemics include mumps, influenza A, and hepatitis B. They have not yet been affected by TB or measles, among others. Infanticide contributes to an estimated infant mortality rate of 568/1000. With a crude birth rate of 38 and a crude mortality rate of 51, the Hagahai appear to be dying out. The provision of adequate health care to these people is extremely problematic and beyond the capacity of the existing system.

National immunization programs carried out in the CSR are here confronted with the EPI regional targets for Europe, a component of the WHO global program "Health for all by the year 2000". The EPI target diseases to be brought under control in Europe by 1990 include measles, poliomyelitis, diphtheria and neonatal tetanus; control of congenital rubella infection is to be achieved by the year 2000. The presented data show that Czechoslovakia has succeeded in implementing this program much ahead of the WHO time schedule. The elimination of measles infection was achieved in 1982, poliomyelitis was brought under control in 1961, and the effective diphtheria control has been in effect since the mid-1960s. Cases of neonatal tetanus are absent in the CSR since 1965, the annual incidence of postnatal tetanus is permanently 0.1-0.2 per 100,000 population. The goal of achieving the rubella-free status and thus the elimination of congenital rubella cases at country level is expected to be reached in the early 1990s. Implementation of the remaining WHO recommendations pertinent to infections other than EPI target diseases appears also satisfactory. Regular immunization against whooping cough, one of the oldest immunization programs in Czechoslovakia, succeeded in effectively eliminating this infection in the early 1970s. Selective immunization campaigns against influenza infection, introduced many years ago, help protect, together with a large-scale use of available chemoprophylactics, some 200,000 individuals every year in CSR. The hepatitis B immunization program was started in 1983 and is primarily limited to health service staff, which is in line with the existing WHO recommendations. Inception of the regular immunization program against mumps is planned for the beginning of 1987.

Humoral response to influenza vaccination being variable in uremic patients and being negatively correlated to red blood cell magnesium (RBC Mg) in non-uremic subjects, RBC Mg as well as plasma concentration of Mg were measured simultaneously with the antibodies titers after 1 and 2 injections of influenza vaccine in 21 non-uremic subjects and 47 patients on chronic hemodialysis. The RBC Mg and plasma Mg (MgP) were significantly higher in the dialysed patients (74 +/- 12 mg/l; 25 +/- 8 mg/l) than in the non-uremic subjects (54 +/- 5 mg/l; 19.4 +/- 1.5 mg/l). Furthermore, in the uremics RBC Mg was correlated to PMg whereas such a correlation was absent in the non-uremic patients. The humoral response of the uremic patients is depressed and becomes comparable to that of the non-uremic subjects after 1 injection only after 2 injections. In the uremic patients, the depressed humoral response is associated with higher RBC Mg (greater than 70 mg/l). The humoral response to influenza vaccine is depressed in uremic patients who have either the HBs antigen or no response to the hepatitis B vaccine but no link has been found between this immune status against the hepatitis B and RBC Mg. In conclusion, the humoral response of the uremic patients to influenza vaccine is depressed so that a second injection is necessary to give them sufficient protection.

To minimize the likelihood of transmission of certain infectious diseases within the hospital, the 5 million US health care personnel are becoming a special target group for immunization programs. A review of immunizations conducted by a hospital employee health service demonstrated that 80% of hospital employees are adequately protected against tetanus/diphtheria, and 97% are immune to rubella. In contrast, only 28% of at-risk employees are immunized against hepatitis B and only 2% are immunized against influenza. Vaccination programs for tetanus/diphtheria and rubella, which are supported by appropriate legislation, are more effective than vaccination programs for hepatitis B and influenza, which are not supported by appropriate legislation.

We describe three patients with chronic autoimmune thrombocytopenia who exhibited transient remission during viral infection (varicella, hepatitis B, and influenza virus pneumopathy). In two patients, a male homosexual and an hemophiliac, thrombocytopenia was associated with AIDS-related complex. The third patient had classic idiopathic thrombocytopenic purpura. The mechanism of these rare remissions is discussed.
