Decreased measles antibody response after measles-mumps-rubella vaccine in infants with colds

We examined the possibility that the common cold or afebrile upper respiratory tract infection might interfere with successful immunization in children who receive standard measles-mumps-rubella vaccine. Infants 15 to 18 months of age presenting at our well-child clinics for routine examination and immunizations were divided into two groups. Those infants with a history and physical findings of upper respiratory tract infection were compared with healthy control group infants who did not have upper respiratory tract infections, and who did not have a history of upper respiratory tract infection symptoms within the previous month. Both groups were studied for their serologic response to measles-mumps-rubella vaccination. Prevaccination serum samples were obtained prior to vaccine administration and postvaccination serum samples were obtained 6 to 8 weeks later. Measles antibody was measured in these serum samples by an indirect fluorescein-tagged antibody test. Ten (21%) of 47 infants with colds failed to develop measles antibody, while only one (2%) of 51 well infants failed to develop antibody. We conclude that infants with colds have a significant seroconversion failure rate associated with measles vaccine administration and that this may be the cause of some primary measles vaccine failures.     

Antibody response and clinical reactions in children given measles vaccine with immunoglobulin

Antibody responses and clinical reactions to three measles vaccines (Attenuvax, Mevilin, and Rimevax) injected into the opposite arm to immunoglobulin were assessed in 45 children with brain disorders making them susceptible to fits if given measles vaccine alone. In this small study no unacceptable reactions occurred and in only three cases was the antibody response minimal or absent. More children in this special category should be considered for vaccination against measles in this way.     

Antibody response to one and two doses of influenza virus subunit vaccine.

Antibody studies were undertaken to evaluate the responses after one and two-dose schedules of influenza immunization with subunit influenza vaccine. The responses were studied in two adult population groups after the administration of a vaccine containing the most recent epidemic strains A/Pt Chalmers/73 and B/Hong Kong/8/73. Responses to the A component of the vaccine were greater than those to the B strain. Patients with initially low antibody levels responded better than those with higher levels. There was little additional benefit from the second dose of vaccine.     

Antibody response in school children to live rubella vaccine (Cendehill strain)

The efficacy of an attenuated rubella virus vaccine, Cendevax, was tested on 65 school children. Forty-nine of them (75%) had pre-existing antibodies and in these there was no increase in the HAI antibody titres after administration of the vaccine. Sixteen children (25%) had no demonstrable rubella HAI antibody prior to vaccination. From the latter group, postvaccination serum samples were available from only 11, and 10 of these seronegative children showed seroconversion after vaccination. The geometric mean HAI titre was 1:180. Seven of the 10 postvaccination serum samples had complement-fixing antibodies and specific IgM antibodies were detected by the immunofluorescence test in 8. No correlation was observed between the CF and the IgM antibodies.

Antibody response in calves following administration of attenuated infectious bovine rhinotracheitis (IBR) vaccines

The serum antibody response of calves vaccinated against infectious bovine rhinotracheitis by the intramuscular route was compared to calves vaccinated subcutaneously. Immunological response in the calves as determined by serum neutralization tests was highly variable; however, a significantly greater percentage (87.5%) of the calves inoculated subcutaneously responded to vaccination by producing a four-week post-vaccinal serum titer of two or higher as compared to only 47.8% of the calves that were vaccinated intramuscularly. Of those calves that were vaccinated a second time, all maintained or had produced titers of two or higher within four weeks after the second immunization. However, the existing circulating serum antibody titers resulting from the first vaccination of nine of 22 calves were lowered by repeat vaccination.     

Acute polyarthritis following the use of Corynebacterium parvum vaccine (Coparvax) for malignant pleural effusion

A 77-year-old man with a malignant pleural effusion was treated by aspiration of fluid and injection of Corynebacterium parvum vaccine for pleurodesis. Within 24 hr he had developed a temperature and a neutropenia followed by an acute crippling polyarthritis of his hands and wrists which subsequently responded to oral steroids and non-steroidal antiinflammatory drugs.
