Combination vaccines have been introduced in Mexico. The national immunization program has incorporated the measles-mumps-rubella (MMR) vaccines in 1998, and the pentavalent vaccine in 1999. The two categories of antigen composition in combination vaccines are: 1) multiple different antigenic types of a single pathogen, such as the 23 valent pneumococcal polysaccharide vaccine, and 2) antigens from different pathogens causing different diseases, such as the DPT and MMR vaccines. Pentavalent vaccines are included in the second category. The vaccine protects against diphtheria, tetanus, pertussis, hepatitis B, and other diseases produced by Haemophilus influenzae type b (Hib). Combined diphtheria, tetanus, pertussis, hepatitis B, and Haemophilus influenza type b (DTP-HB/Hib) vaccine has been distributed to 87% of Mexican children under 1 year of age. Over 800,000 doses of pentavalent vaccine have been administered.

The decreasing tendency in incidence of infectious diseases observed in Poland in previous years as compared with 2000 has weakened or stopped. Increase in the incidence of selected infectious diseases can be linked with the improvement of surveillance resulting from the better diagnostics and greater attention paid to these diseases (including borreliosis, salmonella, and Haemophilus influenzae meningitis). Between 1999 and 2000, the most intense decrease in the number of mumps, measles, and scarlet fever cases as an effect of the end of epidemics was observed. At the same time increase in the number of pertussis, rubella, chickenpox, and meningitis cases was noticed. In 2000, the first case of human rabies since 1986 has been reported. In 2000, compared with 1999, among all notified deaths percentage of deaths attributed to infectious diseases (0.83%) and infectious diseases death rate (0.79 per 10,000) were slightly higher and were the highest in the last decade. As in 1999 the observed increase was effect of the influenza deaths increase (358 deaths, mortality 0.022%). The main disease causing the largest number of deaths, as in previous years, was tuberculosis (36.5% of total infectious diseases deaths).

Until November 2001, eight vaccinations had been offered to Japanese children on a routine basis; namely, diphtheria-tetanus-pertussis, polio, measles, rubella, Japanese encephalitis, and BCG. The 2001 amendment of the Immunization Law introduced an influenza vaccine for the elderly population. This paper reviews the progress of the immunization program in the broader context of infectious disease control in Japan. There are two recent major policy changes in the field of infectious disease control in Japan. One is the strengthening and revitalization of the infectious disease control program, particularly surveillance, by the enactment of new 1999 legislation entitled "Law concerning the Prevention of Infectious Diseases and Patients with Infectious Diseases". The other major policy change is a review of existing immunization programs and the amendment of the Immunization Law in 2001. In this article, the present routine vaccination program, as well as the recent amendments to the law, are described. Current policy issues are then discussed, including polio vaccination after the WHO "Zero Polio" announcement in the Western Pacific Region in 2000; strategies for changes in measles, rubella, tuberculosis, and influenza control; as well as adverse reaction monitoring/surveillance and feedback for improving vaccine safety. Finally, the future prospects of intended/planned changes in the vaccination policy are considered.

The status and likely impact of existing and potential new combined hepatitis B vaccines were broadly considered at the Viral Hepatitis Prevention Board (VHPB) meeting in Malta, October 2001. The currently available and/or licensed combined hepatitis B vaccines in Europe and the prospects for further such vaccines were reviewed. Data on the safety, immunogenicity, and European licensing status and availability of haxavalent vaccines combining hepatitis B (HepB), Haemophilus influenza type b (Hib), diphtheria, tetanus, and pertussis (acellular) (DTPa), and inactivated poliovirus (IPV) antigens were presented. Finally, the impact of the availability of combined hepatitis B vaccines on hepatitis B immunisation programmes in Europe were examined and the added value of combined hepatitis B vaccines globally was estimated.

In 2001 there were 104,187 notifications of communicable diseases in Australia reported to the National Notifiable Diseases Surveillance System (NNDSS). The number of notifications in 2001 was an increase of 16 per cent of those reported in 2000 (89,740) and the largest annual total since the NNDSS commenced in 1991. In 2001, nine new diseases were added to the list of diseases reported to NNDSS and four diseases were removed. The new diseases were cryptosporidiosis, laboratory-confirmed influenza, invasive pneumococcal disease, Japanese encephalitis, Kunjin virus infection, Murray Valley encephalitis virus infection, anthrax, Australian bat lyssavirus, and other lyssaviruses (not elsewhere classified). Bloodborne virus infections remained the most frequently notified disease (29,057 reports, 27.9% of total), followed by sexually transmitted infections (27,647, 26.5%), gastrointestinal diseases (26,086, 25%), vaccine preventable diseases (13,030 (12.5%), vectorborne diseases (5,294, 5.1%), other bacterial infections (1,978, 1.9%), zoonotic infections (1,091, 1%) and four cases of quarantinable diseases. In 2001 there were increases in the number of notifications of incident hepatitis C, chlamydial infections, pertussis, Barmah Forest virus infection and ornithosis. There were decreases in the number of notifications of hepatitis A, Haemophilus influenzae type b infections, measles, rubella, Ross River virus infections and brucellosis. This report also summarises data on communicable diseases from other surveillance systems including the Laboratory Virology and Serology Reporting Scheme and sentinel general practitioner schemes. In addition, this report comments on other important developments in communicable disease control in Australia in 2001.

The increasing number of infant immunisations has spurred development of novel combination vaccines. This investigation assesses the immunogenicity of oral poliomyelitis vaccine (OPV) under current and possible new conditions, to help ensure vaccination regimes continue to provide optimal protection against polio in the final stages of polio eradication. Neutralising antibody titres were measured in approximately 200 infants immunised with OPV at 2, 4 and 6 months in tandem with either a combined pentavalent liquid Haemophilus influenza B (Hib), hepatitis B, diphtheria, tetanus and whole-cell pertussis vaccine or three separate but concurrently administered licensed vaccines (diphtheria, tetanus and whole-cell pertussis (DTP), lyophilised Hib, and hepatitis B). Following three doses of OPV, at least 98% of infants demonstrated neutralising antibodies at 1:8 to each poliovirus type under both vaccination regimes, and geometric mean titres (GMTs) well above the suggested protective titre were also observed for all poliovirus types. OPV appears to be effective not only in producing protective antibody titres in an extremely high proportion of infants when given in combination with currently licensed vaccines, but also when administered together with the combination pentavalent vaccine under study. This is encouraging for the continued role of OPV in infant immunisation.

Preterm (PT) infants are at increased risk of experiencing complications of vaccine-preventable diseases but are less likely to receive immunizations on time. Medically stable PT and low birth weight (LBW) infants should receive full doses of diphtheria, tetanus, acellular pertussis, Haemophilus influenzae type b, hepatitis B, poliovirus, and pneumococcal conjugate vaccines at a chronologic age consistent with the schedule recommended for full-term infants. Infants with birth weight less than 2000 g may require modification of the timing of hepatitis B immunoprophylaxis depending on maternal hepatitis B surface antigen status. All PT and LBW infants benefit from receiving influenza vaccine beginning at 6 months of age before the beginning of and during the influenza season. All vaccines routinely recommended during infancy are safe for use in PT and LBW infants. The occurrence of mild vaccine-attributable adverse events are similar in both full-term and PT vaccine recipients. Although the immunogenicity of some childhood vaccines may be decreased in the smallest PT infants, antibody concentrations achieved usually are protective.

The Epidemiological Surveillance System of Navarra includes the notification of 34 transmissible infectious diseases, to which epidemic outbreaks of any aetiology and cause are added. In 2000, under the heading of diseases of respiratory transmission, 31,106 cases of flu were reported; 80% of total annual cases were reported in the first 6 weeks of the year, with a maximum in week 1 when 7,949 cases were reported. Twelve cases of meningococcal disease were reported to the system. Eight cases were confirmed microbiologically and appeared in a sporadic way. With respect to the causative serogroup, Neisseria meningitidis serogroup B was isolated on 5 occasions. On 2 occasions serogroup C was isolated, and serogroup Y was isolated on 1 occasion. By age groups, 5 cases were declared in infants of 2 years of age (Rate: 57.6 per 100,000), two cases in children between 2 and 4 years of age (14.7 per 100,000), one case in children between 5 and 9 years of age (3.5 per 100,000), two cases between 10 and 19 years of age (2.5 per 100,000) and the remaining 2 cases in persons aged 20 years or over (0.50 per 100,000). Twenty three cases of legionellosis were declared in 2000, all under the clinical form of pneumonia. These were isolated cases in persons of middle or advanced age. No indication was found of prior tourist trips to areas of high prevalence. In the majority of cases the origin was considered to be in the community, while one outbreak was identified as nosocomial. Similarly, there was a notable increase in the declaration of cases of hepatitis A, with 24 cases (EI: 2.00), pertussis, with 23 cases (EI: 1.64) and varicella, with 4,232 reported cases (EI: 1.86).

Nasal vaccines consisting of nonliving particulate formulations can induce immune responses of importance for protection against infection. The most promising results have been obtained with vaccines against influenza, pertussis and group B meningococcal disease. So far, however, the results do not challenge the standing of corresponding injectable vaccines, although results of experiments in animals do indicate that effective nonliving nasal vaccines may soon be developed. This will depend on refined immunization schedules to benefit from immunological memory and on formulations to make the vaccines more accessible to the immune system by way of mucosal adjuvants or immune modulators.

In 2001 surveillance system of infectious diseases in Poland remained unchanged. New cases of infectious diseases were recorded in 103 positions including intoxications. Tuberculosis and sexually transmitted infections were registered in separate systems. Influenza was the most frequently reported infectious disease with 576,449 cases, 63.9% less then in the previous year. The next most numerous were foodborne infections, which were reported in 24,393 cases, including 19,788 cases of infections caused by Salmonella sp. An increase in incidence was observed in the following diseases: viral hepatitis type A, rubella, measles and pertussis. Also the number of recorded cases of Lyme boreliosis and tickborne encephalitis were higher then in 2000. Incidence of AIDS remained within the range recorded during the last few years. In 2001 further drop in incidence of viral hepatitis type B was observed reaching the level of 6.2 per 100,000. It was the result of implemented comprehensive program of prophylactic measures, which brought incidence of this disease from the highest in Europe down to the level close to European average. Infectious diseases contributed to 0.75% of deaths. The most frequent cause of death among infectious diseases was tuberculosis and its sequels (1,061 cases). 13 cases of death due to tuberculosis occurred in people below 30 years of age.
