SUMMARYNormal ferrets did not produce serum antibody following immunization with 200 i.u. of inactivated A/Hong Kong/68 influenza virus vaccine and were found to be susceptible to subsequent challenge infection with A/Hong Kong/68 virus. High titres of virus were recovered from nasal washings collected 3 days after infection, serum antibody was produced, increased nasal protein was detected and HI antibody was detected in nasal washings. Ferrets infected with influenza virus A/PR/8/34 7 weeks before immunization with inactivated A/HK/68 virus did, however, produce serum HI antibody to A/HK/68 virus. This antibody conferred partial immunity to challenge infection with A/HK/68 virus, as shown by decreased titres of virus in nasal washings and reduced levels of nasal protein. Previous infection of ferrets with influenza virus B/Ann Arbor/66 did not result in the production of serum antibody to A/HK/68 virus following immunization with A/HK/68 vaccine and the animals were completely susceptible to subsequent challenge infection with A/HK/68 virus. Differences in the amount of nasal protein and nasal antibody produced after A/HK/68 infection were also found in ferrets previously infected with either A/PR/8/34 or B/AA/66 virus, compared with normal ferrets.

SummaryIn a group of 32 adult volunteers given subunit influenza virus vaccine containing 250 international units (i.u.) of A/Victoria/3/75, 250 i.u. of A/Scotland/ 840/74 and 300 i.u. of B/Hong Kong/8/73, there were substantial increases in the geometric mean homologous haemagglutination-inhibiting (HI) antibody titres. There was also substantial boosting of the antibodies to the earlier variants of the Hong Kong (H3N2) series and to a later variant of the Asian (H2N2) series. There was no boosting of antibodies to the A/FM/1/47 strain, a representative member of the H1N1 series, but two individuals showed substantial rises to A/PR/8/34 (H0N1).There were increases in the HI titre of antibodies cross reactive with two recent isolations, A/Texas/1/77, and A/Victoria/35/77, but the majority of vaccinees failed to reach antibody titres likely to be protective against such strains.
