Post-vaccination symptoms following DTP and DT vaccination.

Post-vaccination symptoms in 6,004 infants given adsorbed Diphtheria Tetanus and Pertussis (DTP) vaccine and 4,024 infants given adsorbed Diphtheria and Tetanus (DT) vaccine have been compared. Although crying, screaming and fever were slightly more frequent after adsorbed DTP than adsorbed DT, attacks of high-pitched screaming, episodes of pallor and hypotonia, convulsions, other neurological disorders and sudden infant death occurred with similar frequency in the two groups. No specific neurological effect attributable to the pertussis component was found.

Effect of rubella vaccination programme on serological status of young adults in United Kingdom.

Antibody to rubella virus was measured in over 10,000 serum samples collected in 1976, 1977, and 1978 from young adult blood donors and university students. The incidence of seronegatives was lower (4--7%) among females born in 1956 and subsequently--i.e., among the age groups offered rubella vaccine at school--than among females born before 1654 (11--20%). The incidence of seronegatives among males in the 1977 and 1978 surveys had the opposite trend, with a higher proportion of seronegatives in younger males, born in 1956 and subsequently, than in older males. The findings provide evidence that the rubella vaccination programme in the U.K. is having a significant impact on the immunological status of young females of childbearing age. Nevertheless too high a proportion of young females remains potentially susceptible to rubella.

Paralytic poliomyelitis in England and Wales 1976-7.

In 1976-7 26 cases of paralytic poliomyelitis were notified, of which 6 were vaccine-associated. 16 of the 20 non-vaccine-associated cases were due to type-u poliovirus, the type usually associated with outbreaks. The most important factor in the increase was the occurrence of poliomyelitis in unvaccinated persons.

Influenza at Christ's Hospital: March, 1974.

Boys in a boarding-school given inactivated influenza-A or influenza-B vaccine have been observed during a simultaneous outbreak of influenza due to A/Port Chalmers, B/Hong Kong, and B/Intermediate strains. Influenza-B vaccine conferred substantial protection, the attack-rates in boys given B vaccine being 24% compared with 45% in a control group. A/Hong Kong vaccine, by preventing infection during the previous influenza A/England outbreak, left the boys vulnerable to influenza A/Port Chalmers. Influenza-A haemagglutination-inhibiting (H.I.) antibody acquired by natural infection was associated with more protection than H.I. antibody induced by vaccination. This difference was not seen with influenza-B H.I. antibody.
