A jet airliner with 54 persons aboard was delayed on the ground for three hours because of engine failure during a takeoff attempt. Most passengers stayed on the airplane during the delay. Within 72 hours, 72 per cent of the passengers became ill with symptoms of cough, fever, fatigue, headache, sore throat and myalgia. One passenger, the apparent index(More)
In a study designed to determine whether cytotoxic T lymphocytes contribute to immunity against influenza virus infection, we inoculated 63 volunteers intranasally with live unattenuated influenza A/Munich/1/79 virus. Over the next seven days clinical observations were made, and the amount of virus shed was measured. The protective effects of preinfection(More)
At a time when outbreaks and sporadic cases of influenza caused a A/Victoria/3/75-like and A/Texas/1/77-like H3N2 strain of influenza were occurring in the Rocky Mountain region of the USA, about 60% of the students of a high school in Cheyenne, Wyoming, were involved in an outbreak of influenza-like illness. Six influenza A(H1N1) virus isolates were(More)
Vaccines prepared with influenza A/swine/1976/37-like virus contained neuraminidase activity comparable to that of H3N2 vaccines, whereas little neuraminidase activity could be detected in influenza A/New Jersey/76 vaccines. In single-dose vaccine studies, A/swine/1976/37-like split-virus vaccine induced antibody to neuraminidase (NAAb) in about 20% of(More)
Thirty-one unprimed children and young adults received an influenza A/USSR/77 vaccine containing 43 microgram of hemagglutinin. Their HAI antibody response was compared to that in 92 age-matched individuals from the 1978 national influenza immunization trial who received 10 and 4 microgram HA vaccines. A dose-related antibody response was observed after the(More)
This paper examines student experiences and perceptions of two models of team-teaching employed at a regional Australian university to teach a large undergraduate marketing subject. The two team-teaching models adopted for use in this subject can be characterised by the large number of team members (ten and six) and the relatively low level of team(More)
Titers of hemagglutination-inhibiting (HAI) antibody were determined for all sera obtained from participants in the 1976 Influenza Vaccine Test Program. At least eight control sera were included in each test during the vaccine trial period for the purpose of monitoring HAI test reproducibility. Estimates of day-to-day reproducibility were defined as the(More)
